The U.S. plans to reduce greenhouse gas emissions dramatically in the next decade. Scientists say it's crucial that the U.S. succeed. Still, many of the positive effects won't arrive for decades.

According to the report, atmospheric concentrations of carbon dioxide, methane and nitrous oxide, not emissions of those gases, surged to new highs last year. A correction was made on May 8, 2024 ...

Forest-based carbon-offset projects need a buffer to guarantee their climate benefits will last – but they may not have ...

A case in point: Turning methane (a powerful greenhouse gas) into carbon dioxide (also a planet-warming pollutant) could help fight climate change, researchers say. It’s not that CO2 isn’t a ...
