The final EPA rule explicitly omitted the report commissioned last year to justify revoking the endangerment finding, citing “concerns raised by some commenters.” By Dennis Pillion When the U.S. Environmental Protection Agency rescinded its bedrock endangerment finding Thursday, it explicitly excluded a controversial report issued last year by the U.S.Continue Reading
The latest United Nations Climate Change Conference (COP30) concluded in November without a roadmap to phase out fossil fuels and without significant progress in strengthening national pledges to reduce climate-altering greenhouse gas emissions. In aggregate, today’s climate policies remain far too unambitious to meet the Paris Agreement’s goal of capping global warming atContinue Reading
Our climate reporter Raymond Zhong has spent more than a month on a South Korean ship in Antarctica with nearly 40 scientists from around the world. Here’s everything he eats in a day.Continue Reading
Sixty thousand years ago, humans in southern Africa were already mastering nature’s chemistry. Scientists have discovered chemical traces of poison from the deadly gifbol plant on ancient quartz arrowheads found in South Africa — the oldest direct evidence of arrow poison ever identified. The find reveals that these early huntersContinue Reading
