Climate science marks a troubling anniversary this week: in June of 1988, NASA scientist James Hansen told Congress that global warming had already begun to affect the world and would only get worse. A sweeping AP analysis finds that in the decades since Hansen’s testimony, global temperatures have risen nearly 1 degree F, while the […]
By Olga Naidenko Mixtures of chemicals commonly found in consumer products are more likely to increase breast cancer risk than the same chemicals individually, according to a new analysis. But safety tests by government regulators don’t routinely evaluate the combined effects of multiple chemical exposures. For a study published in the peer-reviewed journal Toxicological Sciences, […]
By Jan Minx, Dr. Sabine Fuss and Gregory Nemet Despite the ambitious long-term climate goals of the Paris agreement, there remains a distinct lack of success at ushering in immediate and sustained reductions in global CO2 emissions. This cognitive dissonance has seen the topic of “negative emissions“—also known as “carbon dioxide removal”—move into the limelight […]
By Marlene Cimons This is one flying insect you don’t want to swat. It doesn’t bite, sting or spread disease. In fact, someday it could be a life- and climate-saver. In time, it could even be used to survey crops, detect wildfires, poke around in disaster rubble searching for survivors and sniff out gas leaks, […]
Maybe you can’t teach an old dog new tricks, but two recent studies revealed that old forests around the world are full of surprises. In Europe, scientists working to complete the first ever map of the continent’s old growth forests discovered there were more of them than previously believed. And in South America, a study […]
Newly released emails show that the U.S. Environmental Protection Agency (EPA) under Scott Pruitt has routinely been in contact with one of the most prominent climate denier groups, the AP reported this weekend. The emails, obtained under a Freedom of Information Act request by the Environmental Defense Fund and the Southern Environmental Law Center, show […]
A study published Monday in Nature Geoscience discovered a new factor that is lowering the rate at which oceans absorb carbon dioxide, a finding that could have a major impact on future climate change predictions. Currently, around one-fourth of human generated carbon dioxide emissions are absorbed by oceans, making them the world’s largest carbon sink. […]
By Tim Radford Movements of the earth’s crust may mean that global warming driven by greenhouse gases from power stations and vehicle exhausts isn’t the only threat to life the world faces. About 700 million years ago, global temperatures fell so low that glaciers may have reached the equator. Snowball Earth may have all but […]
April 2018 was the 400th consecutive month of global temperatures above the 20th century average, the National Oceanic and Atmospheric Administration ( NOAA) announced Thursday. That means the last time Earth was cooler than that average was December 1984—the same month Band Aid released “Do They Know It’s Christmas.” This three-decade streak is not some […]
