By Mariana Fuentes Have you ever considered that small pieces of plastic less than 5 millimeters long, or smaller than a pencil eraser head, called microplastics, can affect large marine vertebrates like sea turtles? My research team first discovered this disturbing fact when we started to quantify the amount and type of microplastic at loggerhead […]
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 […]
By Tim Radford Hurricanes are becoming more violent, more rapidly, than they did 30 years ago. The cause may be entirely natural, scientists say. But Hurricane Harvey, which in 2017 assaulted the Gulf of Mexico and dumped unprecedented quantities of rain to cause devastating floods in Texas, happened because the waters of the Gulf were […]
A new study from the National Oceanic and Atmospheric Administration (NOAA) shows an “unexpected and persistent increase” in global emissions of an ozone-depleting chemical even though an international treaty forced production to completely halt by 2010. NOAA scientists suggest that emissions are most likely from new, unreported production from an unidentified source in eastern Asia. […]
By Julia Conley With a first-of-its-kind satellite study, NASA scientists have identified more than 30 parts of the globe where the depletion of freshwater has been most dramatic, largely due to human activity and the climate crisis. Parts of India, the Middle East, Australia, the Arctic, Antarctica, and California were among the places pointed out […]
Climate change puts forests at risk. A recent study found that a third of the conifers in the unique Klamath region in California and Oregon could disappear by the end of this century. California has lost 130 million trees since 2010 due to the combined impacts of drought, warming temperatures and the insects and diseases […]
