Exposing the Big Game

What If We Stopped Pretending?

The climate apocalypse is coming. To prepare for it, we need to admit that we can’t prevent it.

“There is infinite hope,” Kafka tells us, “only not for us.” This is a fittingly mystical epigram from a writer whose characters strive for ostensibly reachable goals and, tragically or amusingly, never manage to get any closer to them. But it seems to me, in our rapidly darkening world, that the converse of Kafka’s quip is equally true: There is no hope, except for us.

I’m talking, of course, about climate change. The struggle to rein in global carbon emissions and keep the planet from melting down has the feel of Kafka’s fiction. The goal has been clear for thirty years, and despite earnest efforts we’ve made essentially no progress toward reaching it. Today, the scientific evidence verges on irrefutable. If you’re younger than sixty, you have a good chance of witnessing the radical destabilization of life on earth—massive crop failures, apocalyptic fires, imploding economies, epic flooding, hundreds of millions of refugees fleeing regions made uninhabitable by extreme heat or permanent drought. If you’re under thirty, you’re all but guaranteed to witness it.

If you care about the planet, and about the people and animals who live on it, there are two ways to think about this. You can keep on hoping that catastrophe is preventable, and feel ever more frustrated or enraged by the world’s inaction. Or you can accept that disaster is coming, and begin to rethink what it means to have hope.

Even at this late date, expressions of unrealistic hope continue to abound. Hardly a day seems to pass without my reading that it’s time to “roll up our sleeves” and “save the planet”; that the problem of climate change can be “solved” if we summon the collective will. Although this message was probably still true in 1988, when the science became fully clear, we’ve emitted as much atmospheric carbon in the past thirty years as we did in the previous two centuries of industrialization. The facts have changed, but somehow the message stays the same.

Psychologically, this denial makes sense. Despite the outrageous fact that I’ll soon be dead forever, I live in the present, not the future. Given a choice between an alarming abstraction (death) and the reassuring evidence of my senses (breakfast!), my mind prefers to focus on the latter. The planet, too, is still marvelously intact, still basically normal—seasons changing, another election year coming, new comedies on Netflix—and its impending collapse is even harder to wrap my mind around than death. Other kinds of apocalypse, whether religious or thermonuclear or asteroidal, at least have the binary neatness of dying: one moment the world is there, the next moment it’s gone forever. Climate apocalypse, by contrast, is messy. It will take the form of increasingly severe crises compounding chaotically until civilization begins to fray. Things will get very bad, but maybe not too soon, and maybe not for everyone. Maybe not for me.

ome of the denial, however, is more willful. The evil of the Republican Party’s position on climate science is well known, but denial is entrenched in progressive politics, too, or at least in its rhetoric. The Green New Deal, the blueprint for some of the most substantial proposals put forth on the issue, is still framed as our last chance to avert catastrophe and save the planet, by way of gargantuan renewable-energy projects. Many of the groups that support those proposals deploy the language of “stopping” climate change, or imply that there’s still time to prevent it. Unlike the political right, the left prides itself on listening to climate scientists, who do indeed allow that catastrophe is theoretically avertable. But not everyone seems to be listening carefully. The stress falls on the word theoretically.

Our atmosphere and oceans can absorb only so much heat before climate change, intensified by various feedback loops, spins completely out of control. The consensus among scientists and policy-makers is that we’ll pass this point of no return if the global mean temperature rises by more than two degrees Celsius (maybe a little more, but also maybe a little less). The I.P.C.C.—the Intergovernmental Panel on Climate Change—tells us that, to limit the rise to less than two degrees, we not only need to reverse the trend of the past three decades. We need to approach zero net emissions, globally, in the next three decades.

This is, to say the least, a tall order. It also assumes that you trust the I.P.C.C.’s calculations. New research, described last month in Scientific American, demonstrates that climate scientists, far from exaggerating the threat of climate change, have underestimated its pace and severity. To project the rise in the global mean temperature, scientists rely on complicated atmospheric modelling. They take a host of variables and run them through supercomputers to generate, say, ten thousand different simulations for the coming century, in order to make a “best” prediction of the rise in temperature. When a scientist predicts a rise of two degrees Celsius, she’s merely naming a number about which she’s very confident: the rise will be at least two degrees. The rise might, in fact, be far higher.

As a non-scientist, I do my own kind of modelling. I run various future scenarios through my brain, apply the constraints of human psychology and political reality, take note of the relentless rise in global energy consumption (thus far, the carbon savings provided by renewable energy have been more than offset by consumer demand), and count the scenarios in which collective action averts catastrophe. The scenarios, which I draw from the prescriptions of policy-makers and activists, share certain necessary conditions.

The first condition is that every one of the world’s major polluting countries institute draconian conservation measures, shut down much of its energy and transportation infrastructure, and completely retool its economy. According to a recent paper in Nature, the carbon emissions from existing global infrastructure, if operated through its normal lifetime, will exceed our entire emissions “allowance”—the further gigatons of carbon that can be released without crossing the threshold of catastrophe. (This estimate does not include the thousands of new energy and transportation projects already planned or under construction.) To stay within that allowance, a top-down intervention needs to happen not only in every country but throughout every country. Making New York City a green utopia will not avail if Texans keep pumping oil and driving pickup trucks.

The actions taken by these countries must also be the right ones. Vast sums of government money must be spent without wasting it and without lining the wrong pockets. Here it’s useful to recall the Kafkaesque joke of the European Union’s biofuel mandate, which served to accelerate the deforestation of Indonesia for palm-oil plantations, and the American subsidy of ethanol fuel, which turned out to benefit no one but corn farmers.

Finally, overwhelming numbers of human beings, including millions of government-hating Americans, need to accept high taxes and severe curtailment of their familiar lifestyles without revolting. They must accept the reality of climate change and have faith in the extreme measures taken to combat it. They can’t dismiss news they dislike as fake. They have to set aside nationalism and class and racial resentments. They have to make sacrifices for distant threatened nations and distant future generations. They have to be permanently terrified by hotter summers and more frequent natural disasters, rather than just getting used to them. Every day, instead of thinking about breakfast, they have to think about death.

Call me a pessimist or call me a humanist, but I don’t see human nature fundamentally changing anytime soon. I can run ten thousand scenarios through my model, and in not one of them do I see the two-degree target being met.

To judge from recent opinion polls, which show that a majority of Americans (many of them Republican) are pessimistic about the planet’s future, and from the success of a book like David Wallace-Wells’s harrowing “The Uninhabitable Earth,” which was released this year, I’m not alone in having reached this conclusion. But there continues to be a reluctance to broadcast it. Some climate activists argue that if we publicly admit that the problem can’t be solved, it will discourage people from taking any ameliorative action at all. This seems to me not only a patronizing calculation but an ineffectual one, given how little progress we have to show for it to date. The activists who make it remind me of the religious leaders who fear that, without the promise of eternal salvation, people won’t bother to behave well. In my experience, nonbelievers are no less loving of their neighbors than believers. And so I wonder what might happen if, instead of denying reality, we told ourselves the truth.

First of all, even if we can no longer hope to be saved from two degrees of warming, there’s still a strong practical and ethical case for reducing carbon emissions. In the long run, it probably makes no difference how badly we overshoot two degrees; once the point of no return is passed, the world will become self-transforming. In the shorter term, however, half measures are better than no measures. Halfway cutting our emissions would make the immediate effects of warming somewhat less severe, and it would somewhat postpone the point of no return. The most terrifying thing about climate change is the speed at which it’s advancing, the almost monthly shattering of temperature records. If collective action resulted in just one fewer devastating hurricane, just a few extra years of relative stability, it would be a goal worth pursuing.

In fact, it would be worth pursuing even if it had no effect at all. To fail to conserve a finite resource when conservation measures are available, to needlessly add carbon to the atmosphere when we know very well what carbon is doing to it, is simply wrong. Although the actions of one individual have zero effect on the climate, this doesn’t mean that they’re meaningless. Each of us has an ethical choice to make. During the Protestant Reformation, when “end times” was merely an idea, not the horribly concrete thing it is today, a key doctrinal question was whether you should perform good works because it will get you into Heaven, or whether you should perform them simply because they’re good—because, while Heaven is a question mark, you know that this world would be better if everyone performed them. I can respect the planet, and care about the people with whom I share it, without believing that it will save me.

More than that, a false hope of salvation can be actively harmful. If you persist in believing that catastrophe can be averted, you commit yourself to tackling a problem so immense that it needs to be everyone’s overriding priority forever. One result, weirdly, is a kind of complacency: by voting for green candidates, riding a bicycle to work, avoiding air travel, you might feel that you’ve done everything you can for the only thing worth doing. Whereas, if you accept the reality that the planet will soon overheat to the point of threatening civilization, there’s a whole lot more you should be doing.

Our resources aren’t infinite. Even if we invest much of them in a longest-shot gamble, reducing carbon emissions in the hope that it will save us, it’s unwise to invest all of them. Every billion dollars spent on high-speed trains, which may or may not be suitable for North America, is a billion not banked for disaster preparedness, reparations to inundated countries, or future humanitarian relief. Every renewable-energy mega-project that destroys a living ecosystem—the “green” energy development now occurring in Kenya’s national parks, the giant hydroelectric projects in Brazil, the construction of solar farms in open spaces, rather than in settled areas—erodes the resilience of a natural world already fighting for its life. Soil and water depletion, overuse of pesticides, the devastation of world fisheries—collective will is needed for these problems, too, and, unlike the problem of carbon, they’re within our power to solve. As a bonus, many low-tech conservation actions (restoring forests, preserving grasslands, eating less meat) can reduce our carbon footprint as effectively as massive industrial changes.

All-out war on climate change made sense only as long as it was winnable. Once you accept that we’ve lost it, other kinds of action take on greater meaning. Preparing for fires and floods and refugees is a directly pertinent example. But the impending catastrophe heightens the urgency of almost any world-improving action. In times of increasing chaos, people seek protection in tribalism and armed force, rather than in the rule of law, and our best defense against this kind of dystopia is to maintain functioning democracies, functioning legal systems, functioning communities. In this respect, any movement toward a more just and civil society can now be considered a meaningful climate action. Securing fair elections is a climate action. Combatting extreme wealth inequality is a climate action. Shutting down the hate machines on social media is a climate action. Instituting humane immigration policy, advocating for racial and gender equality, promoting respect for laws and their enforcement, supporting a free and independent press, ridding the country of assault weapons—these are all meaningful climate actions. To survive rising temperatures, every system, whether of the natural world or of the human world, will need to be as strong and healthy as we can make it.

And then there’s the matter of hope. If your hope for the future depends on a wildly optimistic scenario, what will you do ten years from now, when the scenario becomes unworkable even in theory? Give up on the planet entirely? To borrow from the advice of financial planners, I might suggest a more balanced portfolio of hopes, some of them longer-term, most of them shorter. It’s fine to struggle against the constraints of human nature, hoping to mitigate the worst of what’s to come, but it’s just as important to fight smaller, more local battles that you have some realistic hope of winning. Keep doing the right thing for the planet, yes, but also keep trying to save what you love specifically—a community, an institution, a wild place, a species that’s in trouble—and take heart in your small successes. Any good thing you do now is arguably a hedge against the hotter future, but the really meaningful thing is that it’s good today. As long as you have something to love, you have something to hope for.

In Santa Cruz, where I live, there’s an organization called the Homeless Garden Project. On a small working farm at the west end of town, it offers employment, training, support, and a sense of community to members of the city’s homeless population. It can’t “solve” the problem of homelessness, but it’s been changing lives, one at a time, for nearly thirty years. Supporting itself in part by selling organic produce, it contributes more broadly to a revolution in how we think about people in need, the land we depend on, and the natural world around us. In the summer, as a member of its C.S.A. program, I enjoy its kale and strawberries, and in the fall, because the soil is alive and uncontaminated, small migratory birds find sustenance in its furrows.

There may come a time, sooner than any of us likes to think, when the systems of industrial agriculture and global trade break down and homeless people outnumber people with homes. At that point, traditional local farming and strong communities will no longer just be liberal buzzwords. Kindness to neighbors and respect for the land—nurturing healthy soil, wisely managing water, caring for pollinators—will be essential in a crisis and in whatever society survives it. A project like the Homeless Garden offers me the hope that the future, while undoubtedly worse than the present, might also, in some ways, be better. Most of all, though, it gives me hope for today.

It’s Not Just Fires. Your Phone Is Also Destroying The Amazon.

“You could drop a nuclear bomb on the forest, and it would be better than mining it.”

Last updated on August 31, 2019, at 12:00 p.m. ET

An aerial view over a chemically deforested area of the Amazon jungle caused by illegal mining activities in the river basin of the Madre de Dios region in southeast Peru, on May 17, 2019, during the ‘Mercury’ joint operation by Peruvian military and police ongoing since February 2019.

The wildfires ripping through the Amazon have drawn the world’s attention to the destruction of the “lungs of the planet.” Many scientists believe cattle ranchers clearing land caused the flames, spurring groups around the world — including the government of Finland — to call for a boycott of Brazilian beef. But to boycott all of the products damaging the Amazon, you’d have to do much more than give up steak. You’d have to toss out your phone, laptop, wedding band, and anything else with gold in it.

“There’s no way to get the gold out without destroying the forest. The more acres you cut down, the more gold you get. It’s directly proportional,” Miles Silman, the cofounder of Wake Forest University’s Center for Amazonian Scientific Innovation (CINCIA), told

“There’s no way to get the gold out without destroying the forest.”

Fueling that demand is not just the world’s appetite for gold bars and jewelry — the largest categories for which gold is used — but also high tech. Tiny electrical currents are constantly running through your iPhone, Alexa speaker, and laptop — and carrying those currents is gold, a fantastic conductor of electricity that’s also resistant to corrosion. While there isn’t much gold inside a single device — an iPhone 6, for example, contains 0.014 grams, or around 50 cents’ worth — in the aggregate, the amount is staggering. According to market researcher Gartner, over 1.5 billion smartphones were sold last year, with 1.3 billion of them being Android devices. It was followed by 215 million iOS devices.

So the tech industry, which consumes nearly 335 tons of gold yearly, will only need more and more of the metal. “There’s a gold rush in the Amazon right now that’s just like the gold rush that happened in California in the 1850s,” said Silman.

According to a 2018 CINCIA study, artisanal mining, or small-scale mining conducted by independent miners, have uprooted nearly 250,000 acres of rainforest in the Madre de Dios region of Peru, where Silman focuses his work. Another study, by researchers at the University of Puerto Rico in 2015, found that approximately 415,000 acres of tropical forest across South America has been lost to gold mining. A map compiled by environmental group Amazon Geo-Referenced Socio-Environmental Information Network shows 2,312 illegal mining sites in 245 areas across six countries, which the group called an “epidemic.”

And just as the California gold rush gave rise to a lawlessness that took generations to tame, the tech industry’s suppliers can’t always meet demand and sometimes turn to the Amazon’s illegal mining economy.

An artisan miner shows a piece of gold after extraction and processing on May 6, 2008 in El Ingenio, Peru, 420 kms south of Lima. Artisan mining accounts for the livelihood of more than 40 thousand Peruvian families, though almost 15% of the nation’s gold production comes from this activity. Since the 1980s many extracting camps have been converted into small mining towns lacking basic services and containing high levels of pollution.

Miami Herald investigation in 2018 detailed how a handful of traders from Southern Florida–based precious metals company NTR Metals bought $3.6 billion of gold from outlaw mines across South America. NTR Metals has since been shut down and the traders arrested. The company was a subsidiary of Elemetal, a major US gold refinery that supplied Tiffany & Co. and other consumer brands, like Apple, which said it stopped working with the supplier, in corporate disclosures for the year 2017 and 2018.

Apple is far from the only tech giant that sources gold from the Amazon region. A review of corporate disclosures by BuzzFeed News found that Amazon (the company), AppleSamsungSony, and Google list refiners Asahi and Metalor as suppliers. In turn, these firms, based respectively in Switzerland and Japan, buy some of their gold from South American mines. According to the Herald, those companies buy from brokers, who source their gold from a range of legal and illegal mines in the region.

Companies like Alphabet, the parent company of Google, are aware of the impacts of gold mining in the Amazon, and have taken steps to address it. A Google company spokesperson pointed to its conflict minerals policy, and says it relies on third party audits to ensure that smelters are in compliance. Samsung, Sony, and Amazon did not return a request for comment. Apple told BuzzFeed News all its gold refiners participate in third party audits. “If a refiner is unable or unwilling to meet our standards, they will be removed from our supply chain,” an Apple spokesperson said it a statement. “Since 2015, we’ve stopped working with 60 refiners of gold for this reason.”

Dirty gold doesn’t just end up in electronics. A 2015 report by Ojo Publico reported that companies with ties to the London Bullion Market Association — an organization that determines the international price of gold — acquired precious metal from illegal mining camps in Peru, Bolivia, and Brazil.

“A part of the problem with gold is that it all goes into one melting pot. So you can have a bar of gold where some of it comes from responsible sources, some of it comes from illegal sources, but it looks like one bar of gold,” said Sarah duPont, president of the Amazon Aid Foundation.

That illegal and dirty gold extraction takes a toll on the environment and the humans who mine it. Compared to soybean farming or cattle ranching, the mining industry clears fewer acres of forest from the Amazon.

However, according to Silman, the carbon emissions of mining can make the industry’s environmental footprint between three to eight times as big as the surface acres lost to mining might suggest. In addition to uprooting trees and other plants, miners dig two to four meters deep into the ground, where soil is rich in carbon. That soil can be thousands of years old, and gold mining liberates that carbon back into the atmosphere, killing nutrients in the dirt that are vital to plants in the rainforest.

“If you think about an Amazonian forest, there’s nothing you do that’s worse to it than alluvial mining.”

“The growth rates around the mines are so slow because you’ve washed everything that’s good out of the soil,” Silman explained.

Gold mining also transforms the landscape in another way: “1 out of every 5 acres converted by mining can’t be reforested because it’s converted into a body of water. So it ends up looking like Minnesota, with thousands of lakes all across the landscape,” said Silman. “If you think about an Amazonian forest, there’s nothing you do that’s worse to it than alluvial mining. You could drop a nuclear bomb on the forest, and it would be better than mining it.”

On top of the environmental devastation, mercury, used as an amalgam to retrieve gold from the dirt, contaminates the region’s water and food supply. According to the US National Institute of Health, artisanal and small-scale gold mining is the leading source of mercury released into the environment. Researchers have found high levels of mercury, which has serious health effects on the nervous, digestive, and immune systems, in people living along the Brazil–Venezuela border, the Madre de Dios area of Peru, and in Suriname.

Despite the dangers, gold mining in the Amazon region is unlikely to slow down. Brazilian president Jair Bolsonaro has loosened the country’s environmental laws and is working to open up more of the Amazon to mining. Bolsonaro fired the head of the country’s agency that tracks deforestation, after a report that some 1,330 square milesof Amazonian forest in Brazil had been lost since the president took office in January — a 39% increase over last year.

What can be done? According to Kevin Telmer, executive director of the Artisanal Gold Council, an organization working to professionalize and train the sector, the environmental problem is linked to that of extreme poverty.

Banning small-scale mining would not be effective, according to Telmer: “People have asked the miners to leave for 40 years and they haven’t. What [bans] do is drive the economy into the black market.”

“What’s needed really is sustainable economic pathways for those individuals who are currently pursuing illegal mining,” said Payal Sampat, the mining program director at Earthworks, a nonprofit that started a campaign called No Dirty Gold in 2008. Sampat added that buying vintage jewelry and holding on to electronics for longer is a good way for consumers to cut down on their gold consumption.

Silman, the CINCIA researcher, agrees. Legally placed mines, he said, are at least confined to a small area, instead of thousands of mines sprawled across a landscape. Taxing mining operations could also help money flow back into job placement and other programs: “There was $3 billion made out of Madre de Dios, and a lot of it flowed through mafias. There’s a little over 100,000 people living in that land, and they would have had $300 million of tax revenue,” he said.

The formalization and professionalization of the sector can help miners be more productive, and be less impactful on the environment, too, Silman said: “Once you do all these things, at least you can get some good from mining, and you still don’t destroy all the opportunities for the future that rely on biodiversity.”

Beyond Brazil, Unprecedented Fires Are Engulfing Bolivian Forests

Up to 800,000 hectares of the unique Chiquitano forest were burned to the ground in Bolivia between August 18 and August 23. That’s more forest than is usually destroyed across the country in two years. Experts say that it will take at least two centuries to repair the ecological damage done by the fires, while at least 500 species are said to be at risk from the flames.

The Chiquitano dry forest in Bolivia was the largest healthy tropical dry forest in the world. It’s now unclear whether it will retain that status. The forest is home to Indigenous peoples as well as iconic wildlife such as jaguars, giant armadillos, and tapirs. Some species in the Chiquitano are found nowhere else on Earth. Distressing photographs and videos from the area show many animals have burned to death in the recent fires.

The burnt region also encompasses farmland and towns, with thousands of people evacuated and many more affected by the smoke. Food and water are being sent to the region, while children are being kept home from school in many districts where the air pollution is double what is considered extreme. Many families are still without drinking water. While the media has focused on Brazil, Bolivians are asking the world to notice their unfolding tragedy — and to send help in combating the flames.

It’s thought that the fires were started deliberately to clear the land for farming, but quickly got out of control. The perpetrators aren’t known, but Bolivian President Evo Morales has justified people starting fires,saying: “If small families don’t set fires, what are they going to live on?”

The disaster comes just a month after Morales announced a new “supreme decree” aimed at increasing beef production for export.Twenty-one civil society organisations are calling for the repeal of this decree, arguing that it has helped cause the fires and violates Bolivia’s environmental laws. Government officials say that fire setting is a normal activity at this time of year and isn’t linked to the decree.

Morales has repeatedly said that international help isn’t needed, despite having sent just three helicopters to tackle the raging fires. He argued that the fires are dying out in some areas — although they continue to burn in others and have now reached Bolivia’s largest city, Santa Cruz de la Sierra. Many say that the fires could have been contained far sooner with international help, as videos show volunteers trying to beat back the fires with branches.

As the fires worsened, people gathered to protest in Santa Cruz state. Chanting “we want your help”, they complained that the smoke was so bad they were struggling to breathe. They want Morales to request international aid to fight the fires. While firefighters and volunteers struggle to tackle the blaze in 55℃ heat, Bolivians have set up a fundraiserto tackle the fires themselves.

A fortnight after the fires began, a supertanker aeroplane of water arrived, hired from the US. But if the reactions to the president’s announcementon Twitter are anything to go by, many Bolivians think this is too little, too late. Morales is fighting a general election and has faced criticism for staying on the campaign trail while the fires spread.

Some Indigenous leaders are asking for a trial to determine responsibility for the fires, and the response to them. Alex Villca, an Indigenous leader and spokesperson, said:

It is President Evo Morales who should be held accountable. What are these accountabilities going to be? A trial of responsibilities for this number of events that are occurring in the country, this number of violations of Indigenous peoples and also the rights of Mother Nature.

President Morales came to power in Bolivia in 2006, on a platform of socialism, Indigenous rights, and environmental protection. He passed the famous “Law of the Rights of Mother Earth” in 2010, which placed the intrinsic value of nature alongside that of humans. His environmental rhetoric has been strong but his policies have been contradictory. Morales has approved widespread deforestation, as well as roads and gas exploration in national parks.

While the fires in the Chiquitano have dominated the media within the country, hundreds more rage across Bolivia, assisted by the recent drought. It’s unclear whether the response to these fires will affect the October election outcome, but sentiments are running high in the country, where more than 70% of people prioritise environmental protection over economic growth.

Bolsonaro and Brazil might grab the headlines, but Bolivia too is now host to a desperately serious humanitarian and environmental situation.

Trump Reportedly Suggests Using Nukes to Stop Hurricanes

As he refuses to take action to combat the climate crisis, which scientists say is making extreme weather events more intense and devastating, President Donald Trump reportedly suggested deploying America’s vast nuclear arsenal to stop hurricanes from reaching the United States.

Axios reported Sunday that Trump asked, “Why don’t we nuke them?” during a hurricane briefing in the White House.

“They start forming off the coast of Africa, as they’re moving across the Atlantic, we drop a bomb inside the eye of the hurricane and it disrupts it. Why can’t we do that?” Trump said, according to Axios, which cited sources who heard the president’s remarks.

“Trump also raised the idea in another conversation with a senior administration official,” Axios reported. “A 2017 NSC memo describes that second conversation, in which Trump asked whether the administration should bomb hurricanes to stop them from hitting the homeland. A source briefed on the NSC memo said it does not contain the word ‘nuclear’; it just says the president talked about bombing hurricanes.”

In a tweet Monday morning, Trump called Axios‘s story “fake news” and said he never raised the idea of bombing hurricanes, which commentators described as “dangerously moronic” and “absolutely nuts.”

The story by Axios that President Trump wanted to blow up large hurricanes with nuclear weapons prior to reaching shore is ridiculous. I never said this. Just more FAKE NEWS!

The National Oceanic and Atmospheric Administration (NOAA) has a page on its website dedicated to addressing the question, “Why don’t we try to destroy tropical cyclones by nuking them?”

“During each hurricane season, there always appear suggestions that one should simply use nuclear weapons to try and destroy the storms,” the page reads. “Apart from the fact that this might not even alter the storm, this approach neglects the problem that the released radioactive fallout would fairly quickly move with the tradewinds to affect land areas and cause devastating environmental problems.”

“Needless to say,” NOAA concludes, “this is not a good idea.”

Environmentalists were quick to ridicule the president’s reported suggestion and demand action to confront the climate crisis and protect vulnerable communities from extreme weather events.

“We cannot believe we have to say this but elected officials should get their climate policy recommendations from frontline communities and science, not the movie Sharknado,” tweeted 350.org. “What if instead of dropping nuclear bombs on hurricanes we just passed a Green New Deal and made fossil fuel billionaires pay for the devastation of climate disasters?”

Trump only world leader not seen at G-7 meeting on climate

.USA TODAY, Just the FAQs

BIARRITZ, France – President Donald Trump skipped a G-7 session focused on climate and biodiversity that was attended by other world leaders Monday.

When U.S. reporters were ushered into the working session on climate, biodiversity and oceans taking place at the G-7 they saw an empty chair where Trump usually sits. The rest of the G-7 leaders were present.

White House press secretary Stephanie Grisham said the president had other scheduled meetings “so a senior member of the administration attended in his stead.”

Trump has reportedly told aides that the meeting of world leaders has focused too intensely on climate and other environmental issues. White House officials have said the president wants the meeting to deal more with economic issues, and Trump pushed for and secured a session on Saturday focused on the global economy.

Trump has been at odds with other members of the G-7 specifically on climate after he announced in 2017 that the U.S. would formally withdraw from the Paris climate agreement. Then candidate Trump promised to withdraw the U.S. from the accord.

Climate change: Should you fly, drive or take the train?

The climate campaigner Greta Thunberg chose to sail to a UN climate conference in New York in a zero-emissions yacht rather than fly – to highlight the impact of aviation on the environment. The 16-year-old Swede has previously travelled to London and other European cities by train.

Meanwhile the Duke and Duchess of Sussex have faced criticism over opting to fly to Sir Elton John’s villa in Nice in a private jet.

So what is the environmental impact of flying and how do trips by train, car or boat compare?

What are aviation emissions?

Flights produce greenhouse gases – mainly carbon dioxide (CO2) – from burning fuel. These contribute to global warming when released into the atmosphere.

An economy-class return flight from London to New York emits an estimated 0.67 tonnes of CO2 per passenger, according to the calculator from the UN’s civil aviation body, the International Civil Aviation Organization (ICAO).

That’s equivalent to 11% of the average annual emissions for someone in the UK or about the same as those caused by someone living in Ghana over a year.

Aviation contributes about 2% of the world’s global carbon emissions, according to the International Air Transport Association (IATA). It predicts passenger numbers will double to 8.2 billion in 2037..

And as other sectors of the economy become greener – with more wind turbines, for example – aviation’s proportion of total emissions is set to rise.

How do emissions vary?

It depends where passengers sit and whether they are taking a long-haul flight or a shorter one.

The flight figures in the table are for economy class. For long haul flights, carbon emissions per passenger per kilometre travelled are about three times higher for business class and four times higher for first class, according to the Department for Business, Energy and Industrial Strategy (BEIS).

This is because there’s more space per seat, so each person accounts for a larger amount of the whole plane’s pollution.

Taking off uses more fuel than cruising. For shorter flights, this accounts for a larger proportion of the journey. And it means lower emissions for direct flights than multi-leg trips.

Also, newer planes can be more efficient and some airlines and routes are better at filling seats than others. One analysis found wide variation between per passenger emissions for different airlines.

For private jets, although the planes are smaller, the emissions are split between a much smaller number of people.

For example, Prince Harry and Meghan’s recent return flight to Nice would have emitted about four times as much CO2 per person as an equivalent economy flight.

The increased warming effect other, non-CO2, emissions, such as nitrogen oxides, have when they are released at high altitudes can also make a significant difference to emissions calculations.

“The climate effect of non-CO2 emissions from aviation is much greater than the equivalent from other modes of transport, as these non-CO2 greenhouse gases formed at higher altitudes persist for longer than at the surface and also have a stronger warming potential,” Eloise Marais, from the Atmospheric Composition Group, at the University of Leicester, told BBC News.

But there is scientific uncertainty about how this effect should be represented in calculators.

The ICAO excludes it, while the BEIS includes it as an option – using a 90% increase to reflect it.

The EcoPassenger calculator – launched by the International Railways Union in cooperation with the European Environment Agency – says it depends on the height the plane reaches.

Longer flights are at higher altitude, so the calculator multiplies by numbers ranging from 1.27 for flights of 500km (300 miles) to 2.5 for those of more than 1,000km.

In the chart above, the high-altitude, non-CO2 emissions are in a different colour.

How does travelling by train compare?

Train virtually always comes out better than plane, often by a lot. A journey from London to Madrid would emit 43kg (95lb) of CO2 per passenger by train, but 118kg by plane (or 265kg if the non-CO2 emissions are included), according to EcoPassenger.

Chart showing emissions for different journ

However, the margin between train and plane emissions varies, depending on several factors, including the type of train. For electric trains, the way the electricity they use is generated is used to calculate carbon emissions.

Diesel trains’ carbon emissions can be twice those of electric ones. Figures from the UK Rail Safety and Standards board show some diesel locomotives emit more than 90g of C02 per passenger per kilometre, compared with about 45g for an electric Intercity 225, for example.

The source of the electricity can make a big difference if you compare a country such as France, where about 75% of electricity comes from nuclear power, with Poland, where about 80% of grid power is generated from coal.

According to EcoPassenger, for example, a train trip from Paris to Bordeaux (about 500km) emits just 4.4kg of carbon dioxide per passenger, while a journey between the Polish cities of Gdansk and Katowice (about 465km) emits 61.8kg.

As with plane journeys, another factor is how full the train is – a peak-time commuter train will have much lower emissions per person than a late-night rural one, for example.

Can driving be better than flying?

Yes, if the car’s electric – but diesel and petrol cars are also in many cases better options than flying, though it depends on various factors, particularly how many people they’re carrying.

According to EcoPassenger, a journey from London to Madrid can be done with lower emissions per passenger by plane, even accounting for the effect of high altitude non-CO2 emissions, if the car is carrying just one person and the plane is full. If you add just one more person into the vehicle, the car wins out.

Coaches also score well. BEIS says travelling by coach emits 27g of CO2 per person per kilometre, compared with 41g on UK rail (but only 6g on Eurostar) – though again this will vary depending on how full they are and the engine type.

What about travelling by boat?

The BEIS has also put a figure on ferry transport – 18g of CO2 per passenger kilometre for a foot passenger, which is less than a coach, or 128g for a driver and car, which is more like a long-haul flight.

But ferries’ ages and efficiency will vary around the world – and a ferry won’t get you to America, although a cruise ship or ocean liner would.

The cruise industry has long been under pressure to reduce environmental impacts ranging from waste disposal to air pollution, as well as high emissions – not only from travel but also from powering all the on-board facilities.

Carnival Corporation and plc, which owns nine cruise lines, says its 104 ships emit an average of 251g of carbon dioxide equivalent per “available lower berth” per kilometre.

And, while the figures are not directly comparable, they suggest cruising falls in similar territory to flying in terms of emissions.

Humanity Sleep-Walking Toward ‘Mass Extinction’

Politicians ignore the daily alarm bells in the science, whether it is melting Antarctica ice caps or the growing temperatures in the ocean

Next year, the British Government will host the UN Climate talks in London, known as COP26, which are the most important climate talks since Paris in 2015.

So for the next year, the UK will be a critical leader in the global fight against climate change.

For the UK to ask other nations to act, it also has to step up to the plate. And yet it is failing. Badly.

Today, the UK Government’s own experts, the Climate Change Committee (CCC) outlined in its annual report to Parliament, how “Our credibility in the COP26 Presidency rests on real action at home.”

But then they brutally concluded that the “UK action to curb greenhouse gas emissions is lagging behind what is needed to meet legally-binding emissions targets.”

The CCC noted that since June 2018, the British “Government has delivered only 1 of 25 critical policies needed to get emissions reductions back on track.”

Chris Stark, the CCC Chief Executive, said it would be prudent to not only prepare for a 1.5 degree rise in temperature, but also a 2 degree rise, and even a 4 degree rise.

Four degrees is widely seen as completely catastrophic by climate scientists.

So even a country like the UK, which has touted itself as a climate leader, is failing miserably. There is just no political will for any meaningful action.

The politicians ignore the daily alarm bells in the science, whether it is melting Antarctica ice caps or the growing temperatures in the ocean.

For example, earlier this week Daniel Rothman, professor of geophysics and co-director of the Lorenz Center in MIT’s Department of Earth, Atmospheric and Planetary Sciences, released a study in the Proceedings of the National Academy of Sciences examining how the rate at which carbon dioxide is currently entering the oceans could push us past a catastrophic threshold.

This threshold could happen slowly, or even suddenly, but when it does “the Earth may respond with a runaway cascade of chemical feedbacks, leading to extreme ocean acidification that dramatically amplifies the effects of the original trigger.”

As the press release from MIT regarding the study outlined: “Today’s oceans are absorbing carbon about an order of magnitude faster than the worst case in the geologic record.”

We are pumping so much carbon dioxide into the oceans that according to Rothman, today we are “at the precipice” of a threshold of “excitation.” If it occurs, “the resulting spike — as evidenced through ocean acidification, species die-offs, and more — is likely to be similar to past global catastrophes.”

If and when we cross this threshold, the carbon cycle is predicted to react “with a cascade of positive feedbacks that magnified the original trigger, causing the entire system to spike, in the form of severe ocean acidification.”

In other words, “if today’s human-induced emissions cross the threshold and continue beyond it, as Rothman predicts they soon will, the consequences may be just as severe as what the Earth experienced during its previous mass extinctions.”

Rothman’s new research comes two years after he predicted that a mass extinction event could take place as early as the end of this century.

Timothy Lenton, a Professor of Climate Change and Earth Systems Science at the University of Exeter, responded to the study by telling CommonDreams. “If we push the Earth system too far, then it takes over and determines its own response—past that point there will be little we can do about it.” Then we face runaway climate change leading into catastrophic mass extinction.

As with much of the news about climate change, this new research hardly got any press mention. The politicians sleep-walk on.

The magazine Mother Jones recently explored the issue of climate scientists who know “of a looming catastrophe but must struggle to function in a world that does not comprehend what is coming and, worse, largely ignores the warnings of those who do.”

The acutely powerful article details the daily distress of climate scientists, whose warnings are being ignored.

One scientist, Sarah Myhre, a former senior research associate at the University of Washington’s School of Oceanography, experiences “a profound level of grief on a daily basis because of the scale of the crisis that is coming”.

It is not that we didn’t know. It is not that the scientists didn’t warn us. We knew. But Exxonknew too. And it never wanted us to know the truth. And their decades-long denial campaign still has ramifactions today, as politicians refuse to act to the climate emergency that we are in.

One simple reason we aren’t acting faster on climate change?

Images like that of a polar bear on a melting ice field are iconic. But in terms of getting people to act on climate change, they may be ineffective. Here’s why.

 

We’ve all seen how powerful images can make abstract crises feel concrete. Think of the photographs of a Chinese man blocking a column of tanks a day after the Tiananmen Square massacre, a naked Vietnamese girl fleeing from napalm in 1972 or of 7-year-old Amal Hussain wasting away from hunger in Yemen. When done well, photographs help people around the world make sense of unseen disasters.

Now close your eyes and try to picture climate change – one of our generation’s most pressing crises. What comes to mind? Is it smoke coming out of power plants? Solar panels? A skinny polar bear?

That’s problematic, says psychologist Adam Corner, director of Climate Visuals, a project that aims to revitalise climate imagery. “Images without people on them are unable to tell a human story,” says Corner.

And that kind of imagery might be a big part of why so few of us are prioritising climate action.

Climate change has an inherent image problem. While you can clearly visualise plastic pollution or deforestation, climate change has a less obvious mugshot: the gases that cause global warming, such as carbon dioxide and methane, are colourless, while impacts are slow-paced and not always visually striking.

So in the 1990s, reporters, politicians and others began using the sort of imagery that would help us begin to grasp the situation. That idea helped us understand the subject then. But it now needs revamping. For one thing, climate impacts are more evident now: take the frequency of wildfires, coastal flooding, droughts and heat waves.

But another reason to update climate change’s visuals is that, for the general public, ‘traditional’ climate images aren’t that compelling.

Wondering if there was a better way to tell climate change stories, Climate Visuals tested what effect iconic climate images – like that lonely polar bear – really had.

After asking people at panel groups in London and Berlin and through an online survey with over 3,000 people, the team concluded that people were more likely to empathise with images that showed real faces – such as workers installing solar panels, emergency respondents helping victims of a typhoon or farmers building more efficient irrigation systems to combat drought.

It also helped when photographs depicted settings that were local or familiar to the viewer, and when they showed emotionally powerful impacts of climate change.

Respondents in their study were also cynical of ‘staged’ pictures… and of images with politicians.

Climate Visuals’ quest is not entirely new. For over a decade, scholars have analysed the way NGOs and governments represent climate change visually, examined how the public reacts to different types of images and come up with new approaches. What it’s done differently, though, is to create the world’s largest climate image library based on those lessons.

And for better or for worse, it’s no longer that difficult to find human-led photographs of the consequences of climate change.

“The stories we need to tell are all around us in a way they were not 20 years ago when the polar bear became an icon,” says Corner.

WE’RE EATING THIS PLANET TO DEATH

DANIEL ACKER/GETTY IMAGES

THE UN’S INTERGOVERNMENTAL Panel on Climate Change released a dire report today arguing that humanity can’t truly fight climate change without addressing the land problem—habitat degradation, deforestation, and soils beat to hell by agriculture. We now use nearly three-quarters of the world’s ice-free surface and waste a quarter of the food we produce, all while the global food system contributes up to 37 percent of our greenhouse gas emissions.

In short, we have to fundamentally rethink how we grow crops and raise livestock. There’s no cure-all, and every potential fix is fraught with maddening complications. But if we can’t figure out how to feed our species in a more sustainable way, climate change will continue to accelerate, making it all the more difficult to grow enough food. Food systems will collapse, and people will die.

The fundamental problem is that we have finite arable land and an exploding population. And trends that are positive from a social perspective, such as the ascent of the poor into the middle class in booming economies like China’s, end up ratcheting up the demand for meat even more.

So let’s start with meat. Raising livestock for slaughter is, of course, not particularly good for the planet. Animals demand lots of food and water: A single cow might consume 11,000 gallons of water a year. And that cow burps up methane, an extremely potent greenhouse gas.

MATT SIMON COVERS CANNABIS, ROBOTS, AND CLIMATE SCIENCE FOR WIRED.

In labs around the world, researchers are working on an alternative, by trying to get meat cells to grow in petri dishes. Using vats controlled for temperature, oxygen content, and more, they are replicating the conditions inside a cow without the methane side effects. And that, they promise, will be far better for the planet than growing beef out in a field.

But the promise of a lab-grown meat that replaces livestock in a significant manner is still far off. No one has a fully operational facility churning out the stuff. That means there also isn’t much data to show how, exactly, it stacks up against factory farming. “If you’re growing cells, you have to provide them with oxygen and heat and food and clean their waste and all the rest of it,” says Alison Van Eenennaam, an animal geneticist at the UC Davis. “That won’t come free. A cow is keeping its body temperature and doing its own waste removal.”

Labs and cows also release different greenhouse gases. To grow meat in the lab, you need electricity, which means CO2emissions. That CO2 lingers in the atmosphere for thousands of years, whereas the methane released by cows lasts more like 12 years. Powering future lab-grown meat facilities with renewables will be essential to improving the climate-wrecking profile of meat.

But cows are not just raised for their meat. India, for example, has 300 million cattle, three times as many as the US, but most Indians don’t eat beef. What they do use is the dairy; in fact, they are the biggest producers of dairy on the planet. “I don’t have a simple solution for what you do with a country that has the most cattle on Earth and has the lowest beef consumption,” says Van Eenennaam. “Just saying eat less beef doesn’t take care of that problem.”

THE WIRED GUIDE TO CLIMATE CHANGE

There are also regional differences. A cow in one country is not fungible with a cow in another. Raising cows in Latin America or sub-Saharan Africa produces twice the emissions of cattle kept in Europe or the US, because animals in the latter countries are fed more nutritious food and are more likely to be vaccinated and medicated when they get sick. So they reach slaughtering age quicker, which means they have less time to belch methane.

Switching humans to an entirely plant-based diet would solve some of these problems, but not all of them. For one, clearing forests and peatlands—essentially sparser forests laid on a bed of slowing rotting organic matter—to make way for agricultural land destroys essential carbon sinks. Healthy forests sequester CO2 during photosynthesis and store it. In the case of mucky peatlands, they can sequester carbon for perhaps thousands of years.

Also, prior research has shown that increased CO2concentrations in the atmosphere can actually help crops grow. “But now we know that high levels of CO2 in the atmosphere decrease protein values in grain crops, and also some micronutrients like zinc and iron,” says Cynthia Rosenzweig, a coordinating lead author on the report. Lower protein in crops might then make it even harder to wean ourselves off the easy protein of meat.

So we’re caught in a brutal tension here: We need to protect and plant more trees to sequester more carbon, but we also need more land to feed a booming human population. “We can reduce our demand, or we can increase the amount of land we grow stuff on and the number of animals that produce food,” says Van Eenennaam.

Tackling this problem will require looking at every piece of the land-use problem individually, and thinking hard about how we solve each one. For example, one way to lower the demand for food might be to eliminate the massive amount of food that gets wasted every day. But the reasons why food gets wasted vary from place to place. In the US, consumers are responsible for a great deal of it, whereas in the developing world the supply chain is the bigger culprit. There, insufficient refrigeration can cause foods to spoil before they even get to the market. The solution? More refrigeration—which means more emissions and more warming.

“Raising cows in Latin America or sub-Saharan Africa produces twice the emissions of cattle kept in Europe or the US.” —Alison Van Eenennaam, UC Davis

Researchers are racing to develop solutions to the preservation problem—a clever spray, for instance, can double the ripeness window of avocados. Robots, if deployed widely, could help fill in labor gaps and grow fruits and vegetables more efficiently, for example using machine vision to determine optimal ripeness. All great ideas that are still very young.

“The products are coming out faster than the science,” says Gabe Youtsey, chief innovation officer of the University of California’s Agriculture and Natural Resources division. “But there’s definitely a lot of promise there.”

But to make a meaningful impact on climate change, he notes, those new ideas need to be deployed not in isolation, but as part of a larger technological system. A robot that picks apples may help fill a labor gap and get more fruit to market, but that’s just one crop. Our whole food system needs to change, a sort of biotech awakening. So optimizing the supply chain to cut down on food waste, while boosting yields with optimal varietals could allow more food to grow on the same amount of land, preserving more habitats for reforestation.

The vast scale of this crisis can only be tackled through massive, perhaps unparalleled cooperation—everyone needs to find the solutions that work for their corner of the world. But by tailoring solutions to a community, researchers can capitalize on particular customs. In Madagascar, for instance, scientists have launched a program to get folks to ditch bushmeat and eat sustainably farmed crickets, which was already the tradition, but had been forgotten in the country of late. That would be a tougher sell in the US, where lab-grown meat might have a better chance of taking hold.

Changing our ways will be a massive political, cultural, and technological undertaking. But change we must, because we’re eating this planet to death.

Cows, carbon and climate change

With record heat waves, costly fire seasons, rising sea levels, and superstorms wracking our planet, it is clear that human-caused climate disruption is causing major problems for all of Earth’s inhabitants. Fossil fuels have long (and correctly) been identified as the biggest culprits, with the majority of humanity’s atmospheric carbon contribution coming from burning fossil fuels — oil, coal, and natural gas — and reversing hundreds of millions of years of natural carbon sequestration on the part of swamps and forests. However, there is an increasing global awareness that animal agriculture also plays a major role in accelerating climate change.

Cattle and other domestic ruminants have a four-chambered stomach, including a fermentation vat (called a rumen) that enables the animal to use microbes to break down cellulose — the main component of wood, paper and cardboard — into sugar. This fermentation process creates methane, which increases atmospheric temperatures  25 to 84 times as much as carbon dioxide. Thus, cattle, sheep and other livestock boost the carbon dioxide absorbed by plants into a far more climate-potent gas.

Livestock belching, farting and manure emissions of this and other gases has been estimated to account for 14 to 18 percent of the total human-induced greenhouse gases that are responsible for climate change. The remaining 82 to 86 percent of carbon emissions into the atmosphere comes from taking carbon out of the ground and pumping it into the atmosphere, whether through equally-potent methane leaks from natural gas wellfields and pipelines or through burning fuels to produce carbon dioxide. Thanks to the combined effect of greenhouse gases from livestock production and fossil fuel combustion on the world’s climate, the survival of the planet’s life forms, humanity included, is now at risk.

But the livestock also convert and degrade lands, radically reducing carbon sequestration — the natural ability of the biosphere to soak up atmospheric carbon — creating an even greater climate problem than methane emissions themselves. This effect is most obvious in tropical rainforest areas, which are being deforested at an accelerating pace to create pasture lands for livestock. This upsets natural nutrient cycling, as soil nutrients present in rainforest settings quickly leach out of the soil. Following deforestation, the massive carbon banks tied up in rainforest trees, vines and shrubs are gone for the long term. This bankrupting of carbon reserves in the tropics is paired with a catastrophic loss of biodiversity, an environmental crisis co-equal to climate disruption in its severity and significance.

Less visibly but perhaps more importantly, livestock grazing on the world’s grasslands, shrubsteppes and deserts can cause even greater withdrawals from a carbon banking standpoint than cutting down the forests. Livestock grazing eliminates deep-rooted native grasses and wildflowers, replacing them with shallow-rooted annual weeds that thrive in disturbed environments and die every year, releasing their carbon back to the atmosphere. Annual weeds therefore have little ability to store carbon in the soil.

In addition, once rangelands become degraded through overgrazing, shrubs sometimes increase, but clearing these shrubs to stimulate forage production for livestock further cripples the land’s ability to store carbon.

Throughout the Intermountain West, heavy grazing by livestock flips the ecological switch that converts healthy native habitats to an annual weed called cheatgrass, by suppressing the native perennial grasses and destroying the soil crusts that otherwise prevent cheatgrass invasion. Cheatgrass is highly flammable, and the resulting high-frequency range fires can eliminate deep-rooted shrubs, accelerating carbon loss from the soil.

Restoring the 25 million acres of livestock-degraded and cheatgrass-infested rangelands in the western United States back to native shrubs and grasses could offset some 23 percent of all U.S. carbon emissions. Stopping the livestock-induced damage would allow the land to heal over time and regain its carbon-storing capacity.

Natural areas are the lungs of the planet, breathing in carbon dioxide and exhaling oxygen. Personal choices by consumers (adding rooftop solar panels, eating less meat) can help, but they’re not enough to stem the tide. Returning half the Earth to nature would restore carbon reserves while also addressing the biodiversity crisis.

We need major policy initiatives like the Green New Deal to force decisive action, stabilize and slash carbon emissions, and restore healthy levels of carbon sequestration through the natural processes of photosynthesis. Major livestock reforms on America’s western public lands would be a key step forward in this effort.
