A team of 60 international scientists report that by early 2028 society will have emitted enough greenhouse gases that the Earth will be pretty much locked into hitting the internationally agreed upon preferred limit for global warming.

The weeklong heat wave that baked most of the U.S. Southwest in temperatures well into triple digits is on its last legs, but forecasters are still urging people to be cautious.

Las Vegas has set a new record high for the second day in a row and Albuquerque tied its high mark.

National Oceanic and Atmospheric Administration data shows that average temperatures in 2023 were 3.5 degrees above the 20th century average.

A heat wave that's already lasted more than a week keeps on baking the US, Asia and even the Arctic.

For decades, scientists have talked about so-called “committed warming” or the increase in future temperature based on past carbon dioxide emissions that stay in the atmosphere for well over a century. International climate agreements set goals of limiting warming to 2 degrees Celsius (3.6 degrees Fahrenheit) since pre-industrial times, with the more ambitious goal of limiting it to 1.5 degrees Celsius (2.7 degrees Fahrenheit) added in Paris in 2015. The world has already warmed about 1.1 degrees Celsius (2 degrees Fahrenheit). “You’ve got some ... global warming inertia that’s going to cause the climate system to keep warming, and that’s essentially what we’re calculating,” said study co-author Andrew Dessler, a climate scientist at Texas A&M University.
