Scientists warn that greenhouse gas accumulation is accelerating and more extreme weather will come

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. That is less than three years away and a year sooner than what the same team calculated in 2024. The threshold is when the world will be committed to 1.5 degrees Celsius of long-term warming since preindustrial times. One scientist and co-author of the report says things aren't just getting worse, they are getting worse faster. The Thursday report's lead author calls it a depressing picture.
