Robinson Meyer at The Atlantic writes—Are We as Doomed as That New York Magazine Article Says?
[...] In a widely shared article, David Wallace-Wells sketches the bleakest possible scenario for global warming. He warns of a planet so awash in greenhouse gas that Brooklyn’s heat waves will rival Bahrain’s. The breadbaskets of China and the United States will enter a debilitating and everlasting drought, he says. And millions of brains will so lack oxygen that they’ll slip into a carbon-induced confusion.
Unless we take aggressive action, “parts of the Earth will likely become close to uninhabitable, and other parts horrifically inhospitable, as soon as the end of this century,” he writes. “No matter how well-informed you are, you are surely not alarmed enough.”
It’s a scary vision—which is okay, because climate change is scary. It is also an unusually specific and severe depiction of what global warming will do to the planet. And though Wallace-Wells makes it clear that he’s not predicting the future, only trying to spin out the consequences of the best available science today, it’s fair to ask: Is it realistic? Will this heat-wracked doomsday come to pass?
Many climate scientists and professional science communicators say no. Wallace-Wells’s article, they say, often flies beyond the realm of what researchers think is likely. I have to agree with them.
At key points in his piece, Wallace-Wells posits facts that mainstream climate science cannot support. In the introduction, he suggests that the world’s permafrost will belch all of its methane into the atmosphere as it melts, accelerating the planet’s warming in the decades to come. We don’t know everything about methane yet, but the picture does not seem this bleak. Melting permafrost will emit methane, and methane is an ultra-potent greenhouse gas, but scientists do not think so much it will escape in the coming century.
“The science on this is much more nuanced and doesn’t support the notion of a game-changing, planet-melting methane bomb,” writes Michael Mann, a climate scientist at Penn State, in a Facebook post. “It is unclear that much of this frozen methane can be readily mobilized by projected warming.” [...]

“The only ethical principle which has made science possible is that the truth shall be told all the time. If we do not penalize false statements made in error, we open up the way for false statements by intention. And a false statement of fact, made deliberately, is the most serious crime a scientist can commit.”

At Daily Kos on this date in 2012—House Republicans plan to throw as many as three million people off food assistance:
Poverty is never a life status to aspire to, but it seems to be getting harder and harder to avoid, and increasingly punishing if you're there. With austerity so in vogue these days, it's getting even worse. Last month, the Senate passed a Farm Bill that slashes food assistance through the Supplemental Assistance Nutrition Program (SNAP, formerly known as the Food Stamp Program) by $4.5 billion over the next decade.
"Oh, yeah?" said the House Agriculture Committee. "We'll just up that by about
"Oh, yeah?" said the House Agriculture Committee. "We'll just up that by about about $12 billion more." In that post, Laura Clawson explained who exactly this would hit. If you're a family of three, and have total income of more than $24,100 annually, you'd be out of luck. And food.
