The impacts of human-caused climate change are so overwhelming they’re actually messing with time, according to new research. Polar ice melt caused by global warming is changing the speed of Earth’s rotation and increasing the length of each day, in a trend set to accelerate over this century as humans continue to pump out planet-heating pollution, according to the study published Monday in the Proceedings of the National Academy of Sciences. The changes are small — a matter of milliseconds a day — but in our high-tech, hyperconnected world have an important impact on computing systems we have come to...

Scientists in South Korea have announced a new world record for the length of time they sustained temperatures of 100 million degrees Celsius — seven times hotter than the sun’s core — during a nuclear fusion experiment, in what they say is an important step forward for this futuristic energy technology.

After a summer of record-breaking heat, vast swaths of the United States are now grappling with extreme cold as a brutal Arctic blast brings snow squalls, deadly ice and life-threatening wind chills. As unprecedented heat makes way for cold, it can provide fuel for climate-change deniers who point to freezing temperatures as evidence that global warming is overstated. But scientists are clear: cold extremes will still occur even as winters warm overall. Global heat records outpace cold records — 2023 was the hottest year on record by a huge margin. And even as the US struggles to cope with intense...
