Health officials issue warnings as UK bakes in first heat wave of 2025

British health officials are warning people across the country to take precautions when out in the sun as the U.K. bakes under its first heat wave of the year.

Temperatures are expected to peak at 34 degrees Celsius (93 degrees Fahrenheit) in some parts of eastern England on Saturday following a week of unusually warm weather, according to the national weather agency the Met Office. That's about 12 C (22 F) higher than normal for this time of year.

Greenhouse gas accumulation accelerating, more extreme weather will come

Humans are on track to release so much greenhouse gas in less than three years that a key threshold for limiting global warming will be nearly unavoidable, according to a study to be released Thursday.

The report predicts that society will have emitted enough carbon dioxide by early 2028 that crossing an important long-term temperature boundary will be more likely than not. The scientists calculate that by that point there will be enough of the heat-trapping gas in the atmosphere to create a 50-50 chance or greater that the world will be locked in to 1.5 degrees Celsius (2.7 degrees Fahrenheit) of long-term warming since preindustrial times. That level of gas accumulation, which comes from the burning of fuels like gasoline, oil and coal, is sooner than the same group of 60 international scientists calculated in a study last year.

U.S. officials proposed Monday to protect the pangolin, a small, nocturnal mammal covered in scales, under the Endangered Species Act.

The pangolin is "the most trafficked mammal in the world" in large part for its scales, used in traditional Chinese medicine, and meat, according to the World Wildlife Fund.

Planetary waves linked to wild summer weather have tripled since 1950

Climate change has tripled the frequency of atmospheric wave events linked to extreme summer weather in the last 75 years and that may explain why long-range computer forecasts keep underestimating the surge in killer heat waves, droughts and floods, a new study says.

In the 1950s, Earth averaged about one extreme weather-inducing planetary wave event a summer, but now it is getting about three per summer, according to a study in Monday's Proceedings of the National Academy of Sciences. Planetary waves are connected to 2021's deadly and unprecedented Pacific Northwest heat wave, the 2010 Russian heatwave and Pakistan flooding and the 2003 killer European heatwave, the study said.
