A climate bomb is ticking, and the latest report from the world’s leading climate science body is a how-to guide for defusing it, says United Nations Secretary General António Guterres.

Scientists have long warned that climate change and other threats will require relocating some endangered species outside their historic ranges. Now, U.S. officials are proposing rules that would enable them to use this new — and potentially controversial — conservation tool.

António Guterres is at COP27 in Egypt for what is likely to be another blistering attack on complacency and foot-dragging by world leaders.

As carbon dioxide levels rise and the Earth’s poles warm, researchers are predicting a decline in the planet’s wind speeds. This "stilling" could impact wind energy production and plant growth and might even affect the Gulf Stream, which drives much of the world’s climate.
