Ever since the Intergovernmental Panel on Climate Change (IPCC) was created more than three decades ago, it has faced challenges to its legitimacy. Over that time, these threats came almost exclusively from those opposed to action on climate change. Now that seems to be changing. Today, there is a new effort underway to delegitimize mainstream climate science, and it’s being waged by climate activists.
A common tactic of delegitimization is to characterize an entire group or organization to be in error simply by virtue of who they are or what they believe. An example of this tactic is the argument that the reports of the Intergovernmental Panel on Climate Change (IPCC) are biased because it is affiliated…
However, this only tells part of the story. Carbon dioxide is not alone in its role as a greenhouse gas, with many others contributing significantly to global temperature rises. As humanity struggles to keep warming below 2 degrees C over the century, strategies will be needed to tackle the problem on all fronts.
THERE’S A BAD SMELL AROUND METHANE
Ruminant animals are a major source of greenhouse gas emissions, which is probably no surprise to some.

In a bizarre twist of fate, an Arkansas hunter was killed after a deer that he had just shot attacked him, according to reports. Wildlife officials said that Thomas Alexander, 66, had shot the buck using a muzzleloader while hunting near Yellville, Marion County.
According to Keith Stephens, Chief of Communications at the Arkansas Game and Fish Commission (AGFC)—which investigated the death—Alexander then approached the deer to check if he had killed it.
“I’ve worked for the Game and Fish Commission for 20 years, and it’s one of the stranger things that’s happened,” Stephens told KY3.
“I don’t know how long he left it there, but he went up to check it to make sure it was dead. And evidently it wasn’t,” he said.
Allowing hunters to shoot Yellowstone bison in a narrow gulch just over the national park’s boundaries has put people in the area at risk, according to an Oct. 21 lawsuit filed in the District of Columbia.
The bison, because of the park’s high altitudes, must descend to lower winter feeding grounds, crossing park boundaries and losing hunting protections in the process.
Beattie Gulch is a bottleneck for the herds following the “easiest route” to those winter pastures, according to the complaint filed in the U.S. District Court for the District of Columbia by a group called the Neighbors against Bison Slaughter. And the National Park Service’s approval of hunting bison in the tight confines of the gulch…
WEBSTER, S.D. (AP) — A duck hunter from Minnesota has drowned in a South Dakota lake.
Day County Sheriff Ryan Rucktaeschel says three Minneapolis area men were duck hunting on Bitter Lake near Waubay late Saturday morning when their boat began taking on water.
Two Watertown men also on the lake heard cries for help. KWAT reports the men were able to rescue two of the hunters, who were taken to a hospital to be treated for hypothermia.
Conservation officers recovered the body of the 38-year-old man who drowned in 14 feet of water.
The sheriff says life jackets were on the boat. Authorities are investigating why the boat sank, but the sheriff says it may have been due to “overloading” of people and hunting gear.
Researchers take inspiration from cotton candy to make a gelatin scaffolding, which could help realize the dream of more sustainable steaks and chicken breasts.

When Cypher is selling out his compatriots over dinner with Agent Smith in The Matrix, he muses: “I know this steak doesn’t exist. I know that when I put it in my mouth, the Matrix is telling my brain that it is juicy and delicious. After nine years, you know what I realize? Ignorance is bliss.”
In a simulation like the Matrix, ones and zeroes represent every nuance of that steak—the texture, the smell, the flavor. Here in 2019, scientists are still stuck in the lab, racing to reverse-engineer animal flesh component by component, with the goal of one day feeding the carnivores among us in a (theoretically) more sustainable way. To that end, Harvard researchers have taken inspiration from a cotton candy machine to develop a kind of meat scaffold made of thin strands of gelatin that mimic muscle fibers, on which animals cells grow. It’s a step toward steaks, chicken breasts, and pulled pork grown in a factory instead of a field—but before you get too hungry, understand that it’ll be quite some time before slabs of lab-grown meat land on your plate.

So, about that cotton candy machine: The carnival version works by heating sugar in a container and spinning it at high speed, flinging the sugar out and crystalizing it into strands, which form into a cloud, usually colored pink. Same principle behind the machine these researchers pieced together—though theirs spins much faster, at 30,000 rpm. And pardon this next metaphor, but the next component is a sort of toilet bowl. “If you put that cotton candy machine upside down in a toilet bowl full of solvent, you could spin a whole lot of fibers,” says Harvard bioengineer Kit Parker, a coauthor on a new paper describing the work.

The solvent, a mixture of ethanol and water, keeps the fibers from falling apart as they fling out of the supercharged cotton candy machine. The fibers themselves are made of pig-derived gelatin, which is a product of broken-down collagen. In a regular steak, collagen forms what’s known as the extracellular matrix, or the scaffolding that holds the meat together. How it’s cooked, then, defines its structure and flavor. For instance, you’ve probably had at least one terribly cooked steak that curls up at the edges. “It’s not very tasty, it’s pretty dry,” says Parker. “The collagen curled up instead of transitioning into gelatin.” By contrast, in slow-cooked pulled pork, the low temperatures give collagen the chance to turn into flavor-packed gelatin. And by using gelatin to make these fibers, the researchers can create a tender meat analog.
Speaking of pulled pork, you know how it comes apart into that mass of fibers? That’s because skeletal muscle cells fuse together into long strands. With these lab-spun gelatin fibers, the researchers provided a similar kind of scaffolding, to which they added either cow or rabbit cells. “You don’t want the cells to be like bricks in a brick building,” says Parker. “You want them to be nice and long, like that pulled pork. So having these long fibers, the cells attach to the fibers and they form protein junctions, and then they grow along the length of the fiber.”

The end product is a meat analog whose consistency rivals the real thing. Parker and his colleagues ran a “texture profile analysis”—more or less a little metal hammer that presses down on the material to test its consistency. “Lo and behold, the chewability, or the toughness of this meat, is pretty similar to the other kinds of meat that you might see in the store,” adds Parker.
Now, some big caveats here: The researchers didn’t do a taste test because for one, this isn’t a food-safe lab. Also, this lab-grown meat isn’t cooked, which will transform it in complex, yet to be studied ways. And growing the animal cells—whether in a petri dish, as other lab-grown meat companies are tinkering with, or on these gelatin fibers—is still a tricky process that requires the right temperature, moisture, and nutrient content.

It’s all very expensive, in large part because the process requires pricey animal-derived serums to nourish the growing cells. But the focus on the cost of lab-grown meat has overshadowed some of the industry’s challenges with nailing the chewiness. “Up until this point, a lot of the talk has been about reducing costs and scaling up,” says Elliot Swartz, senior scientist the Good Food Institute, which promotes the lab-grown meat industry. “All those things are extremely important, but there’s also a lot of work to be done on this replication of texture to make these products that consumers are going to want to buy.”
At the moment, companies can grow animal cells to make unstructured products like ground beef or chorizo just fine, because it’s a mush of meat. But to actually replicate a steak in the lab—hoo boy, that’s going to take some work. Not only does the meat have to grow in nice fibers, you have to incorporate connective tissues and fat—that critical component that makes a rib eye so good and lean chicken kinda meh. If it all comes together and lab-grown steaks eventually are what’s for dinner, they’ll be meticulously engineered foods that somehow look and smell like meat before and after cooking, and then somehow taste and feel like meat in your mouth.

Wildlife in western Montana has taken a beating in recent weeks, with two grizzly bear cubs killed on railroad tracks recently southeast of Trego and a bull moose poached southwest of Clinton.
The death of the two cubs brings the total to 44 known or probable grizzly bear mortalities in the Northern Continental Divide Ecosystem (NCDE) across northwest Montana, challenging the troubling record of 46 deaths last year.
Grizzly bears are listed as threatened in the lower 48 states under the Endangered Species Act.
Of the 2019 mortalities, eight involved train collisions, which is…
A Sanders County woman earlier this month accidentally shot and wounded her 10-year-old daughter in a grouse hunting accident, according to Montana Fish, Wildlife and Parks. It was believed to be the first hunting-related shooting incident of the year.
Wayde Cooperider, FWP outdoor skills and safety supervisor, told Lee Newspapers on Tuesday the woman was unloading her .22 magnum on Oct. 11 when the firearm inadvertently discharged a round through the vehicle door, striking her daughter. The girl was transported to the hospital, Cooperider said.
The Sanders County Sheriff’s Office is conducting the investigation. Sanders County Sheriff Tom Rummel did not return a call from the Missoulian seeking further information on the girl’s condition and the investigation.
General rifle season begins in Montana on Oct. 26 for deer and elk. On Tuesday, Cooperider warned residents to be rigorous about their firearm safety measures.
“Be extra cautious,” he said. “Please unload your firearms away from your vehicle.”
Do not transport loaded firearms, and if hunting with another party, check each other’s firearms to make sure they are unloaded, Cooperider added.
The woman was with her children hunting forest grouse, he said. Her children were in the backseat while the vehicle was parked. When she got out to harvest a bird, she was unloading the firearm and it went off, Cooperider said. Another vehicle was approaching during the time of the accident, he said.

While Cooperider believes this is the first hunting-related shooting incident in 2019, he said its possible others have gone unreported.
“Montana is not a mandatory reporting state, which means I find out about this stuff either through our wardens or the news media,” he said.
Just last week, a Helena man was sentenced to nearly 3 1/2 years in state prison for an accidental fatal shooting after a hunting trip in 2018. Gregg Trude pleaded guilty to the charge in September, admitting he had placed a loaded firearm on the backseat of his truck before it discharged and killed Helena Dr. Eugene “Buzz” Walton.
Last hunting season, Montana experienced more hunting-related injuries and deaths than the past several combined, FWP said in an Oct. 18 release.
In the release, Cooperider reminded hunters of the four firearm rules taught at every Hunter Education course: “Always point your muzzle in a safe direction. Always treat every gun as if it were loaded. Always keep your finger off the trigger until ready to fire. Always be sure of your target and beyond.”
“The merits or practice of walking around with a chambered round when big game hunting can be debated extensively,” Cooperider said in the release. “However, I believe it should always come down to ‘best safety practice.'”
HARRISON COUNTY, Iowa (KTIV) – Divers have recovered the body of a Nebraska kayaker and hunter who went missing Friday night.
The body has been identified as 33-year-old Cody Bengford, of Bellevue, Nebraska.
Investigators believe Bengford left the boat ramp at the Nobles Lake Wildlife Management Area on Friday afternoon to head out for a bow hunt in the Desoto National Wildlife Refuge. Bengford was reported missing that evening after he didn’t return. Two DNR Conservation Officers responded and began search and rescue efforts. Bengford’s overturned kayak was recovered a short time later along the north shoreline of the lake, however his body was not found. Search and rescue operations were suspended at 1:46am and resumed around 7:00am Saturday morning.
DNR Conservation Officers were assisted by the US Fish and Wildlife Service, Council Bluffs Fire Department, Harrison and Shelby County sheriff’s offices, Harrison and…
This Monday, Queen Elizabeth II took a stand against trophy hunting in her
speech <https://www.youtube.com/watch?v=KA2SJoOgRSQ> before the British
