The Arctic’s ‘Carbon Bomb’ Could Screw the Climate Even More

The Arctic's ‘Carbon Bomb’ Could Screw the Climate Even More

This story was originally published by Grist and is reproduced here as part of the Climate Desk collaboration. Even in a dream-come-true scenario where we manage to stop all the world’s carbon emissions overnight, the Arctic would inevitably get hotter and hotter. That’s according to a new report by UN Environment, which says the the region is already “locked in” to wintertime warming of 4 to 5 degrees C (7.2 to 9 degrees F) over temperatures of the late 1900s.

This App Lets Kenya’s Farmers Access Satellite Data to Monitor Crops

Climate change is the most horrific threat our species has ever known: No matter how powerful you are or how much money you have, our transforming planet is a reckoning for every one of us. But there are degrees to this misery. If you’re perched in a Manhattan penthouse, the effects might not be immediately apparent (because you don’t care or aren’t paying attention, or both). If you’re a subsistence farmer in Kenya, the situation is already much more dire.

How Google Keeps Its Power-Hungry Operations Carbon Neutral

How Google Keeps Its Power-Hungry Operations Carbon Neutral

Kate Brandt has a radical idea for how we’ll have to live in the future, if we’re going to be in balance with nature. She envisions a world without landfills, where ownership is obsolete, and everything down to the socks on our feet is rented and shared. Brandt is Google’s sustainability officer. And she’s obsessed with one idea: the “circular economy,” which aims to eliminate waste. This would require products and materials to be kept in use, rather than thrown

Bitcoin Will Burn the Planet Down. The Question: How Fast?

Bitcoin Will Burn the Planet Down. The Question: How Fast?

Max Krause was thinking of buying some bitcoin, as one does. But Krause is an engineer—mostly he works on modeling greenhouse gas emissions from landfills—so his first step was to run the numbers. He looked at price, of course, but also how fast the world’s bitcoin miners create new bitcoins and the ledger that accounts for them. And he looked at how much electricity that would seem to require. “I thought, man, this is a lot of energy,” Krause says.

This scientist keeps winning bets against climate deniers

James Annan keeps winning.  Annan, a climate scientist and director of the Blue Skies Research Organization, has won numerous bets over the last decade against scientists from a variety of academic backgrounds.  In short, people keep betting him that the world will cool or warm slightly, rather than continue on its accelerating warming trend. Annan hasn’t lost. Most recently, Annan won $10,000 from two solar physicists at the Institute of Solar-Terrestrial Physics in Russia — Galina Mashnich and Vladimir Bashkirtsev

Massive walls might halt the collapse of thawing Antarctic ice sheets

A NASA plane captured this picture while flying over the Thwaites Ice Shelf.

It would be best for humanity if the colossal ice sheets that blanket Antarctica stayed put. But, there’s growing evidence that as the planet heats up, these sprawling glaciers could begin flowing into the ocean at an accelerated pace, boosting sea levels not in feet — but yards. To halt the melting ice, some scientists have now proposed an ambitious geoengineering plan: constructing massive undersea walls to keep Antarctica’s ice in place.  As Earth’s temperature continues to rise due to
