An unusual threat is looming off the Atlantic coast of Africa. Now roughly 2000 kilometres wide the mass that scientists are calling “the blob” has lingered off the coast for a year and a half and has set size records.

Fresh research published in Geophysical Research Letters has examined the causes and impacts of this anomaly, which has grown more recently.

The blob has changed water-circulation patterns, affected inland weather and reshuffled ecosystems at sea. Although scientists say the planet’s warming oceans may not be responsible for the mysterious and long-lived anomaly, some see it as an early warning of changes that might be coming to Africa in the next few decades.

Satellite imagery first alerted scientists to the strange formation in August 2013, when the roundish blob was seen over the Atlantic. Researchers don’t know what to think…

Don’t be fooled by Jeb Bush’s new rhetoric on climate change

http://grist.org/climate-energy/dont-be-fooled-by-jeb-bushs-new-rhetoric-on-climate-change/?utm_source=newsletter&utm_medium=email&utm_term=EDIT%20Weekly&utm_campaign=weekly

Jeb Bush said some stuff about climate change on Friday that sounded “moderate.” That is a shift from past statements that put him pretty squarely in the denier camp. But resist the urge to be impressed. He still doesn’t actually want to do anything about the problem.

Speaking at an event in New Hampshire, Bush said:

The climate is changing and I’m concerned about that. But to be honest with you, I’m more concerned about the hollowing out of our country, the hollowing out of our industrial core, the hollowing out of our ability to compete in an increasingly competitive world.

With that, he promotes the stale old idea that climate action will inevitably hurt the U.S. economy. But of course, ignoring climate change comes with its own huge costs. And aggressively shifting to clean energy and efficiency would offer huge economic benefits.

Bush went on:

Right now we are one of the countries that has reduced carbon emissions because of the natural gas revolution, converting from coal, and conservation — the two things that have driven a reduction in CO2 emissions. We can continue to reduce carbon emissions by taking advantage of the abundance of natural gas.

Translation: Keep on fracking!

And more from Bush:

We need to restore our competitive posture, which I think our energy revolution will allow us to do, and then simultaneously with that, be cognizant of the fact that we have this climate change issue and we need to work with the rest of the world to negotiate a way to reduce carbon emissions. We are reducing it. The rest of the world is the place where, certainly in the emerging world, where you have greatest challenges.

So in there he talks about negotiating with the rest of the world, which might sound nice. You can almost imagine Jeb pushing for a strong U.N. climate deal in Paris later this year! Except not. Because almost in the same breath he criticizes “the emerging world” — read: China, India, et al. — for really being the source of the problem. This is another stale old idea Republicans like to push — that China and India are slacking so there’s no point in the U.S. doing more. Republicans keep pushing this line even though China is taking pretty dramatic action these days.

And Republicans like Bush, of course, don’t acknowledge that the U.S. has spewed far more carbon dioxide into the atmosphere since 1850 than any other nation, making us the single biggest cause of global warming. Nor do they acknowledge that the U.S., as a wealthy nation with some of the highest per capita emissions, has more of a moral responsibility to act than countries like India, where 400 million people still don’t even have electricity.

NextGen Climate, Tom Steyer’s political group, chose to see Bush’s comments in a positive light: “Jeb Bush demonstrated leadership today on the issue of climate change—distancing himself from the other Republican presidential hopefuls and demonstrating why climate change doesn’t have to be a partisan issue.” If all you have to do to be a Republican climate “leader” is not be a denier, then I guess Bush qualifies.

I take a more skeptical view. Jeb is just adopting the new strategy preferred by the GOP establishment (as explained last week by David Roberts): stop denying the science, because that makes Republicans look stupid, and instead criticize all proposed solutions for costing too much or being ineffective or unfair. You get the same gridlock, the same lack of action, but you’re less of a target for mockery. We can already see other Republican presidential wannabes, like Carly Fiorina and Lindsey Graham, adopting the same approach.

This might look like progress, but it’s not.

NOAA proposes de-listing Humpback Whales

Agency proposes taking humpbacks whales off endangered list

The federal government on Monday proposed removing most of the world’s
humpback whale population from the endangered species list, saying they
have rebounded after 45 years of protections.

National Oceanic and Atmospheric Administration Fisheries wants to
reclassify humpbacks into 14 distinct populations, and remove 10 of those
from the list.

“As we learn more about the species — and realize the populations are
largely independent of each other — managing them separately allows us to
focus protection on the animals that need it the most,” Eileen Sobeck,
assistant NOAA administrator for fisheries, said in a statement.

Humpbacks were listed as endangered in 1970, four years after the
International Whaling Commission banned commercial whaling.

The whales have rebounded in the North Pacific since the listing, which
requires federal approval for federally funded or authorized activities
that could harm whales or their habitat.

Last year, the state of Alaska filed a petition to remove some North
Pacific humpback whales from protection under the Endangered Species Act.
That population, estimated at more than 5,800, feeds in Alaska in the
summer and breeds in Hawaii in winter.

Environmental groups have said North Pacific whales continue to be
vulnerable to factors including increased shipping, climate change and
ocean acidification, which affects the prey stock.

The NOAA said in a release announcing its proposal that protection and
restoration efforts have led to an increase in humpbacks in many areas.

Under the plan, two of the populations would be listed as threatened, in
Central America and the Western North Pacific. The agency said these whales
at times enter U.S. waters.

The other two populations — in the Arabian Sea and off Cape Verde and
northwest Africa — would remain listed as endangered.

Humpbacks are found around the world. They weigh 25 to 40 tons and can grow
up to 60 feet long, according to NOAA’s website. The whales are primarily
dark gray with some white spots, and their pectoral fins can get as long as
15 feet.

If the proposal passes, the humpback populations that are removed from the
endangered list would still be protected under the Marine Mammal Protection
Act.

The public has 90 days to comment on the recommended changes.

Graphic Video Of Annual Canadian Seal Hunt Released By Animal Rights Group

I can’t watch, it just makes me want to club someone…
http://www.huffingtonpost.com/2015/04/20/canada-baby-seals-killed_n_7087092.html

WARNING: This post contains graphic content that may upset some readers.10264634_10152337495904586_9174164310757903244_n

The Canadian government in early March announced this year’s quota for its annual, and highly controversial, seal hunt. The allocation for 2015? 468,000 harp, hooded and grey seals.

In an effort to minimize inhumane treatment, the Canadian government mandates that seals can only be killed using a high-powered rifle or shotgun, a club or a hunting tool called a hakapik. Yet with the hunt in full swing, last week Humane Society International released shocking footage of baby seals being shot, clubbed and dragged aboard hunting vessels — footage that, the group alleges, shows the hunt is anything but humane

Rebecca Aldworth, executive director of HSI’s Canada chapter, told The Huffington Post that despite the legal protections, “what happens to these baby seals is some of the worst suffering I’ve ever witnessed.” She spent last week in a helicopter off the northeast coast of Newfoundland getting a firsthand look at the seal hunt — her 17th year doing so.

“Ever year we go out there, we see the same kind of cruelty,” Aldworth said. “The seal is moving on the ice, the ice is moving on the ocean and the boat is rocking on the waves, so you often see a seal that’s just wounded because it’s incredibly difficult to make that shot.”

The hunt takes place in northeastern Canada between November and June, with the majority of the seal hunting happening in March and April. The animals are killed mainly for their furs, and young harp seals tend to be in the highest demand because they have the most valuable pelts.

The Canadian government maintains that safeguards are in place to ensure animals are killed quickly and humanely. When asked about the scientific rationale for the hunt, a spokesperson for the country’s Fisheries and Oceans Portfolio directed HuffPost to an online FAQ page about the seal hunt.

The huge annual quota is all the more surprising given that the number of seals harvested each year has fallen dramatically over the past decade, thanks to a shrinking market. Around 94,000 animals were hunted in 2013, down from about 366,000 in 2004. Harp seal populations in Canada are nearly three times what they were in the 1970s, currently numbering close to 7.3 million animals.

The Canadian Sealers Association recently announced that it will scale back operations in light of the difficult financial situation caused by a constricted commercial market. Carino, the top buyer of sealskins in Canada, said it wouldn’t be purchasing any pelts this year because it already has a stockpile that didn’t sell in 2014.

The lower demand is partially a result of growing international concern for animal welfare. The entirety of the European Union banned the trade in 2009 due to worries about the inhumane nature of seal hunts in Canada, Greenland, Namibia and other countries. Canada appealed the decision to the World Trade Organization, but the agency upheld the EU ban in 2014, noting it was “necessary to protect public morals” related to animal rights.

In the U.S., trade in seal products is banned and all species of seal are protected under the Marine Mammal Protection Act of 1972.

Captain Paul Watson, founder of the marine wildlife conservation group Sea Shepherd, told HuffPost that while his organization supports the work of HSI, it no longer actively opposes to the hunt due to the “collapse” of the market.

“There simply is no market today,” he said. “Sea Shepherd’s role has been to oppose the sealing ships, and there are no more ships on the water and in the ice killing seals.”

Watson noted that despite the large number of seals designated for hunting through the government’s quota, it’s likely that fewer than 60,000 will be killed this year because of the lack of demand.

Aldworth told HuffPost that HSI is hoping to help broker a deal between the sealers and the Canadian government that would bring about an end to the hunt through a federal buyout of sealing contracts. She said the plan would be similar to the shift that took place when whaling was ended in the country in the 1970s. Parts of Canada now have a burgeoning whale-watching industry.

But for now, her group believes a single seal killed is one too many.

“HSI’s concern is that the seal hunt is inherently inhumane. Because it’s inhumane, it must be shut down,” Aldworth said. “The only progressive thing to do, the only acceptable solution is to shut down the slaughter forever.”

250 Native Elk Die Inside Fenced-in Area at Point Reyes National Seashore

250 Native Elk Die Inside Fenced-in Area at Point Reyes National Seashore

Despite High Mortality, Park Service Considering Plan to Remove or
Fence Free-roaming Elk at Behest of Ranchers

POINT REYES, Calif.— The National Park Service has acknowledged that that more than 250 tule elk died inside the fenced Pierce Point Elk Preserve at California’s Point Reyes National Seashore from 2012 to 2014, likely due to lack of access to year-round water. While nearly half the elk inside the fenced area died, free-roaming Point Reyes elk herds with access to water increased by nearly a third during the same period.

The news comes as the Park Service considers a ranch management plan to either remove or fence in some of the free-roaming elk herds, while extending park cattle grazing leases for up to 20 years.

“Tule elk need room to roam, and native wildlife in our national park should not be fenced in or prevented from finding water and food,” said Jeff Miller with the Center for Biological Diversity. “The loss of nearly half the Pierce Point elk herd highlights how important it is that the Park Service not cave to commercial ranchers who want free-roaming Point Reyes elk fenced in.”

Tule elk are native and endemic to California. There were once 500,000 tule elk in the state but by the late 1800s impacts from cattle ranching and hunting had reduced them to only 28 elk. From one surviving herd, tule elk were reintroduced throughout the state and there are now 4,300 elk in 25 herds. Tule elk were returned to Pierce Point at Point Reyes in 1978, and a free-ranging herd was established in the park in 1998. Point Reyes Seashore is the only national park with tule elk.

The Pierce Point herd declined from 540 elk in fall of 2012 to 286 elk by 2014, a drop of 47 percent. There are no natural year-round fresh water sources on Pierce Point and the elk in the preserve are prevented from migrating by a large, elk-proof fence. During the same drought period, the free-roaming Point Reyes elk herds — which had access to water — increased by 32 percent. The Limantour herd grew from 94 to 120 elk and the Drakes Beach herd increased from 66 to 92 elk.

Cattle ranchers who enjoy heavily subsidized cattle grazing leases on public lands within the national seashore are lobbying the Park Service toremove or fence out the free-roaming elk from ranching areas, because elk are eating grass they believe should be reserved solely for their cattle. The Park Service is considering evicting the free-roaming elk under a planning process initiated for 28,000 acres of leased dairy and beef cattle ranches within the park and Golden Gate National Recreation Area lands in Marin County administered by the national seashore. The Park Service is also proposing extending ranching leases for up to 20 years, and may allow ranchers to expand their operations to animals other than cattle, which would create more conflicts between livestock and native wildlife.

“The reintroduction of elk to the Point Reyes peninsula is a success story for conservation of native species, but the elk are in jeopardy of eviction to benefit a few lease holders,” said Miller. “The Park Service already prioritizes commercial cattle grazing in Point Reyes. Now these subsidized ranchers want to dictate park policies that could eliminate native elk and harm predators and other wildlife.”

Background
There are 13 cows for every elk in the national seashore, with nearly 6,500 dairy and beef cattle and only 498 elk. One-quarter of the national seashore is devoted to commercial cattle operations, with grazing on nearly 18,000 acres under 39 leases. Ten ranching families were paid $19.6 million by the public from 1963 to 1978 for the purchase of ranch lands added to Point Reyes National Seashore. Many of those same families still enjoy heavily subsidized grazing lease rates within the park, paying one-half to one-third the cost they would pay for non-federal grazing land in Marin.

The Park Service is required under its enabling legislation to manage the seashore “without impairment of its natural values” and for “maximum protection, restoration, and preservation of the natural environment.” Restoring native wildlife and ecosystem processes is supposed to be one of the primary missions of the Park Service.

Elk graze on grasses and flowering plants and also browse shrubs and trees. Unlike cattle, elk move around to take advantage of seasonal food sources. Elk can reduce fire danger by browsing brush that is unpalatable to cattle, without impacts to water quality. Extensive studies have documented the negative environmental impacts of overgrazing cattle, including erosion and soil loss, water pollution, degradation of wetland and stream habitats and spread of invasive plants.

Cattle-ranching requires excessive amounts of water — each beef and dairy cow drinks 12 and 35 gallons of water per day, respectively. Accounting for all water use, a typical dairy farm with around 700 cows can use over 3 million gallons of water every day; and every pound of California beef requires about 2,464 gallons of water to produce.

Point Reyes ranchers raise the specter of Johne’s disease as a reason for evicting the Point Reyes elk.Johne’s is a wasting disease of domestic livestock that is spread from confined cattle to wild ruminants such as elk and deer. It is documented that Point Reyes cattle infected the Pierce Point elk herd with the disease. The disease takes 3 to 4 years to produce symptoms. By that time, milk production of most dairy cows peaks and they are removed for slaughter, but infected elk begin to waste away. The Park Service reports that more than 200 recent testing samples show no evidence of the disease in the free-roaming elk. Despite previous high rates of cattle infection in Point Reyes dairies, the Park Service does not require testing or reporting of the disease.

The Center for Biological Diversity is a national, nonprofit conservation organization with more than 825,000 members and online activists dedicated to the protection of endangered species and wild places.

“You know that feeling of joy someone gets when they put an arrow through a giraffe’s eye…..No, me neither”*

*Recent Tweet by Ricky Gervis

Rebecca Francis has been famous in hunting circles since 2010, when the photogenic Utah native won the obscure reality show “Extreme Huntress.”

But now she’s famous in the wider world as well, thanks to comedian Ricky Gervais.

Last week, Gervais, a dedicated animal-rights activist with more than 7 million Twitter followers, came upon a photo of Francis posing next to a giraffe she had just killed, a big smile spread across her face. The result: a tweet heard ’round the world.

CCdg2FaWgAAHhrY

“What must’ve happened to you in your life to make you want to kill a beautiful animal & then lie next to it smiling?”

Ricky Gervais         @rickygervais

People outraged by Francis’ apparently cavalier attitude toward killing wildlife expressed their disgust on social media and beyond.

Stunned by the criticism, Francis struck back, accusing Gervais of sexism. “Ricky Gervais has used his power and influence to specifically target women in the hunting industry and has sparked thousands of people to call for my death, the death of my family and many other women who hunt,” she said in a statement. She added: “I repeat I will never apologize for being a woman who hunts as I know that my passion for hunting and conservation is making a direct difference on the ground for wildlife.”

In the wake of Gervais’ giraffe tweet, a few people on Twitter did call for violence toward Francis. Some of Francis’ supporters have also suggested violence is the answer. One hunting enthusiast tweeted: “@rickygervais a real hunter would shoot idiots like you for the greater good of society.” Gervais retweeted it.

On her website, Francis boasts of having “taken” bears, moose, sheep, zebra and many other animals with both bows and rifles, and of mentoring other women who are interested in hunting. “For me, there is nothing more empowering than sharing that special moment of success with another female who is chasing her dreams,” she writes.

Gervais responded to Francis’ sexism claim by tweeting as if he were Francis: “I kill lions, giraffes & bears with guns and bows and arrows then pose grinning. Why don’t people like me? Must be because they’re sexist.” He then highlighted male hunters too, employing his usual un-PC humor.

Such as Tweeting, “Maybe he was hungry,” under this photo:

Francis has gone quiet in recent days, but Gervais, whose Twitter feed often features his house cat Ollie, gives no indication that he’s done.

Public Overwhelmingly Supports Free-ranging Tule Elk Herd

Public Overwhelmingly Supports Free-ranging Tule Elk Herd at Point Reyes National Seashore

Ranchers Lobbying Park Service to Remove or Fence Out Native Elk

POINT REYES, Calif.— The vast majority of 3,000 public comments on a ranch-management plan for Point Reyes National Seashore support allowing a free-roaming tule elk herd to stay at Outer Point Reyes rather than being fenced in or removed. The comments were released today by the National Park Service as part of a planning process initiated for 28,000 acres of dairy and beef cattle ranches within the national park.

“Point Reyes tule elk are highly beloved by visitors, photographers, naturalists and locals alike. The public doesn’t want these elk relocated, fenced into an exhibit, shot, sterilized or any of the other absurd proposals from ranchers who enjoy subsidized grazing privileges in our national seashore,” said Jeff Miller with the Center for Biological Diversity. “This is the only national park with native tule elk — it’s not a ‘national ranch’ or a zoo exhibit, and it shouldn’t be managed that way. If the park takes any steps toward fencing or relocating elk, it will create a legal and public-relations fight that it will lose.”

The Park Service is considering extending existing ranching leases for up to 20 years. The management plan will address concerns about alleged conflicts between tule elk and ranch operations. The Point Reyes Seashore Ranchers Association, Marin Supervisor Steve Kinsey and Congressman Jared Huffman are demanding that the Park Service remove free-ranging tule elk from the “pastoral zone” or build an extraordinarily large, environmentally damaging elk-proof fence to keep elk out of ranching areas. Many ranchers claim that elk cause economic impacts by eating grass they believe belongs solely to their cattle.

“Tule elk are an ecologically important part of the landscape of Point Reyes National Seashore, while cattle grazing permits are a privilege and certainly not a free pass to try to dictate Park Service policy that harms park wildlife,” said Todd Steiner, biologist and executive director of Turtle Island Restoration Network. “Ranching and wild elk herds can coexist at the seashore, but if ranchers want to manufacture a fight over cattle versus elk, they are likely to quickly learn that the vast majority of Americans rightly choose wildlife over cows in our parks.”

The ranchers in the national seashore enjoy heavily subsidized cattle grazing lease rates on public lands within the park. They bizarrely characterize native tule elk as “invasive” because they were extirpated in the 1800s when ranchers and market hunters eliminated them from the Point Reyes peninsula and most of California. Tule elk were reintroduced to Point Reyes in 1978, and a free-ranging elk herd was established in the park in 1998.

Background
Tule elk have been grazing the Point Reyes peninsula for about 10,000 years, except during from the late 1800s, when they were eliminated from most of California. They returned in 1978 when the National Park Service reintroduced elk to Tomales Point. Tule elk have taken well to reintroduction, and the Tomales Point herd is one of the largest of the 22 herds in California, with a stable population of 450 elk, which are fenced in on the remote point.

The Park Service last prepared an elk management plan in 1998, with an environmental assessment considering alternatives for managing elk on Tomales Point, and decided on a plan to establish a free-ranging herd within the park. The Park Service reintroduced 28 tule elk to the Limantour wilderness area in 1998. The Limantour herd has grown to 65 elk, and a sub-herd established itself near Drakes Beach, now numbering 55 elk, nowhere near the park’s stated management limit of 250-350 elk. The 1998 reintroduction plan allowed capture and relocation of wayward elk, contraception of elk in the event of the herd surpassing 250-350 elk, and even killing aggressive elk that had conflicts with cattle ranches, which has only happened once.

The Park Service is required to manage Point Reyes National Seashore “without impairment of its natural values” and for “maximum protection, restoration, and preservation of the natural environment.” The reintroduction of elk to the Point Reyes peninsula is a success story for conservation of native species and restoring ecosystem processes, one of the primary missions of the National Park Service. Free‐ranging elk, as browsers, play an important role in reducing fire danger by reducing brush that is unpalatable to cattle, and without negative impacts to water quality.

Some of the ranchers at the national seashore routinely violate their lease conditions by stocking excess cattle, allowing cattle to trespass out of the pastoral zone (where they are eating forage needed by wildlife) and raising animals not allowed in their leases — with no consequences. Public-lands ranchers at the seashore pay less than half of the grazing rent they would pay outside the park on private lands ($7 to $9 per animal unit month inside the park compared with $15 to $20 outside), which already more than compensates these livestock operators for any wildlife impacts.

I Was an Animal Experimenter

By

How did it happen? How did I go from being a high school student who played in a rock band to a mad scientist conducting cruel animal experiments?

To this day, I’m not sure. As a child, I liked animals. Growing up, I loved playing with our family dog. I wasn’t particularly interested in science and didn’t even want to go to college. I was planning on making it big as a rock musician, but in 1966, when my band broke up and a college offered me a generous financial aid package, I found myself a depressed, bewildered freshman at a university. I wanted to study music, but without classical training, that door was closed.

561599_4740870687337_1697822471_n

At the end of freshman year, my roommate told me about a great psychology course he was taking where he studied B. F. Skinner’s experiments with rats and pigeons. I was amazed that someone was actually able to predict and control behavior. Why people behaved as they did had always been a mystery to me. So I decided to take the course.

I was fascinated by one class lab where we taught pigeons to peck at a colored disc for food. In my junior year, I attended a class in which the professor made a compelling argument for conducting animal research related to punishment. He promoted it as having the noble goal of finding ways to minimize the use of punishment in humans while maximizing its effect. When he announced he was looking for a student to work in his lab for class credit, I took the job.

First, I had to learn how to shock a pigeon. A graduate student demonstrated how one person held the pigeon upside down while the other plucked out the feathers in back of its legs, cut two lengths of stiff stainless steel wire from a spool and pushed them through the skin and under the pelvic bones. The wires were then soldered to a harness placed on the pigeon’s back. The harness contained a plug that would be connected to a source of electric shock during experiments. No anesthetic or sedative was used.

One day, while programming an experiment, I accidentally touched the electrodes and got a jolting shock that numbed my entire arm. I was amazed that, according to my professor, the shock level was the correct one to use for pigeons. I told myself that pigeons must not feel pain as much as I did.

The pigeons lived in individual wire cages about a cubic foot in volume, in a bleak, windowless cinder-block room. I was told that everyone had to take a turn killing the pigeons after the experiments were finished. A graduate student showed me how to dump a couple of dozen birds into a clear plastic garbage bag, then pour a splash of chloroform on them and tie the bag shut. I remember the first and only time I did the killing; I thought the birds on the bottom were already suffocating because they were completely buried in other birds.

In graduate school, and later as a research technician, I also conducted punishment experiments on rats. The rats were deprived of food or water for 23 hours each day so they would be motivated to press a lever or lick a tube to receive a small reward of food or water. After learning that behavior, they would be shocked through metal rods on the floor for pressing the lever or licking the tube. We were recording how much the pressing or licking was suppressed by the shock.

Each year dozens of animals would be brought into the lab to live their brief lives suffering deprivation and shocks before being killed. At least in graduate school and as a research technician I did not have to kill the animals. There was a full-time lab custodian who took care of that.

As I look back on this nearly 50 years later,…
