Levels of the three “most important” greenhouse gases — methane, carbon dioxide and nitrous oxide — in the atmosphere reached record highs again in 2023, according to research conducted by scientists with the National Oceanic and Atmospheric Administration (NOAA)’s Global Monitoring Laboratory (GML). Air samples taken by GML indicated that levels of the heat-trapping gases […]
Scientists have found a way to fight the climate crisis with plastic waste. A University of Rice research team discovered that heating plastic waste in the presence of a certain chemical created particles that had the ability to absorb carbon dioxide.
By Joe Lo The burning Amazon rainforests, with their jaguars, monkeys and colorful birds, have grabbed global attention in a way the destruction of the world’s mossy peatlands never has. Yet protecting the world’s peatlands, which store at least twice as much carbon as forests, is critical in the fight against climate change. Peatlands, also […]
By Tim Radford For the entire 2.5 million years of the Ice Age epoch called the Pleistocene, it was a low-carbon world. Atmospheric carbon dioxide hovered around 230 parts per million. Not only did Homo sapiens evolve on a low-carbon planet, so did Homo erectus and most other human species now known only from fossil […]
By Daniel Ross Ten years ago, two climate scientists, Mark Jacobson and Mark Delucchi, published a groundbreaking article in Scientific American outlining a road map for becoming 100 percent reliant on energy generated by water, wind and sun by 2030. This was something that needed to be done “if the world has any hope of […]
The atmospheric concentrations of the three gases most responsible for climate change reached record highs in 2017, the most recent annual Greenhouse Gas Bulletin released Thursday from the UN’s World Meteorological Organization (WMO) found. The concentration of carbon dioxide in the atmosphere is now at 405.5 parts per million (ppm), or 146 percent of pre-1750 […]
Today is election day in the U.S., which means that if you are a U.S. voter whose state doesn’t have early voting, today is the day to head to the polls and make your voice heard. A lot of the races in this year’s midterm election have big consequences for the environment. The Sierra Club […]
When new technologies like electricity or the dishwasher took off in the 20th century, most of the people racing to adapt them had no idea what trading candles for light bulbs would do to the Earth’s climate. Researchers at the University of Hawaii have set out to make sure that doesn’t happen again when it […]
Total U.S. greenhouse gas emissions decreased by 2.7 percent between 2016 and 2017, according to a report released by the U.S. Environmental Protection Agency (EPA) released on Wednesday. Andrew Wheeler, the acting administrator of the EPA, touted that the report shows that regulations are unnecessary to slash carbon emissions. “Thanks to President Trump’s regulatory reform […]
