The amount of snowfall is an important parameter used in modeling how the Antarctic continent’s mass of ice will change in the coming decades. As the planet warms, the margins of the continent are melting three times faster than just one decade ago.
The Green New Deal is often linked to Alexandria Ocasio-Cortez, the freshman congresswoman who is the idea’s most visible champion. But in its current form, it’s the brainchild of a bunch of 20-somethings sick of older generations’ inaction on climate change.
Dire warnings about climate change made headlines this fall, but it wasn’t all bad news: Cape Town avoided Day Zero, kids led grown-ups in action on global warming, and scientists launched Antarctic research to better predict rising seas.
The current crisis is only the beginning for residents displaced by devastating explosions at the Chinese port of Tianjin. Traces of cyanide and other toxic chemicals have been reported in the air, which have prompted further questions and concerns.
Trees are nature's tool for pulling carbon dioxide out of the air, but there aren't enough trees in the world to suck up all the CO2 humans are putting there. That's why researchers are pushing to create artificial leaves to help fight climate change. The World's Ari Daniel visits with two teams of researchers pursuing different approaches to the formidable challenge.
Researchers believe that artificial photosynthesis that sucks excess CO2 out of the air could one day help fight climate change. But capturing the gas is only half the challenge. The other half is what to do with it once you've got it. Lauren Sommer reports on a potentially breakthrough technology that uses artificial photsynthesis to turn CO2 from the air into industrial chemicals and natural gas.
The illegal charcoal trade is a big contributor to deforestation in countries like Tanzania. After trying and failing once to curb the business, the country is now trying a new approach. The World's Sam Eaton has the story.
It's always been hot in the Persian Gulf region. But a new report finds that without action to limit climate change, the combination of rising temperatures and humidity will often push much of the region beyond the limits of human adaptability.
On Thursday, word came that ExxonMobil is being investigated for possibly misleading shareholders on the risks climate change poses to its business. On Friday, President Obama killed the Keystone XL oil pipeline to the US from Canada, citing the threat of climate change from burning fossil fuels. The oil business has seen worse weeks, but perhaps not many.
