Biden Administration to Repeal Trump Rule Aimed at Curbing E.P.A.’s Power
The cost-benefit rule limited the way the E.P.A. could justify clean air regulations. Its repeal will take effect in 30 days.

The Biden administration moved to repeal a Trump rule that weakened the government’s ability to curb air pollution and combat climate change.

The regulation curbed the power of the E.P.A. by distorting the cost of reducing air pollution. Its repeal will take effect within 30 days.

Environmental activists praised the move. “Americans can now expect stronger clean air and climate safeguards without unnecessary bureaucratic delays,” said the clean air director of an environmental group.

Antarctic ice sheet retreat could trigger chain reaction
The Antarctic ice sheet was even more unstable in the past than previously thought, and at times possibly came close to collapse, new research suggests.

The findings raise concerns that, in a warmer climate, exposing the land underneath the ice sheet as it retreats will increase rainfall on Antarctica, and this could trigger processes that accelerate further ice loss.

The research is based on climate modelling and data comparisons for the Middle Miocene (13-17 million years ago) when atmospheric carbon dioxide and global temperatures reached levels similar to those expected by the end of this century.

Climate Change is the defining issue of our time and we are at a defining moment. From shifting weather patterns that threaten food production, to rising sea levels that increase the risk of catastrophic flooding, the impacts of climate change are global in scope and unprecedented in scale. Without drastic action today, adapting to these impacts in the future will be more difficult and costly.
