Oceans Break Heat Record for Third Year in a Row

The world’s oceans reached their hottest levels on record in 2021. It’s the third year in a row it’s happened, and it’s driven almost entirely by human-caused climate change, scientists announced yesterday. The findings are presented in a paper published in the journal Advances in Atmospheric Sciences. As excess heat accumulates in the atmosphere, caused by continued greenhouse … Read more

Fires Doubled Australia’s Carbon Emissions–Ecosystems May Never Soak It Back Up

Bush fire season is underway again in Australia, where summer has just kicked off. Yet the country is still recovering from record-breaking wildfires two years ago that killed at least 33 people, destroyed thousands of homes and burned more than 65,000 square miles of land.

Triggered by weeks of unusually heavy rain, it was one of the worst environmental disasters the region had experienced in years. More than four years later, scientists are concerned that it could happen again. … Read more

Wildfires Broke Records around the World in 2021

Carbon emissions from wildfires broke records around the world this summer, according to the European Union’s Copernicus Atmosphere Monitoring Service. Parts of Siberia produced their highest fire-related emissions since the agency first began keeping tabs in 2003. Ditto for the western United States. Altogether, wildfires worldwide spewed about 1.76 billion metric tons of carbon into the atmosphere. … Read more

The Five Biggest Climate Stories of 2021

It feels like we are lurching from one disaster to another: as wildfires blaze across part of the country, a hurricane swamps a different area—and all this happens as a pandemic continues to rage.

Moving CO2 from Air to Oceans May Be Necessary to Slow Warming

Climbing concentrations of carbon dioxide make it likely that humans will have to move some gases from the atmosphere into the oceans to prevent crippling effects of climate change, the National Academies said in a major report released yesterday. It came after months of deliberation among top U.S. scientists who concluded that global efforts to … Read more
