IPCC scenarios are projections, not predictions. "The future has not been written. There is no fate but what we make for ourselves." We get to decide what the world will look like in 2100. gmd.copernicus.org/articles/13/...

As climate scientists, it sucks to be defunded. But it adds insult to injury to be defunded by this moron who has access to the best climate science and data in the world and still says asinine things like this.

Things you learn in an elevator: In Switzerland, it is illegal to own a single guinea pig because these animals need social interaction.
An elevator screen with a black frame displays trivia in French about guinea pig ownership. The blue screen shows a clock in the top-left corner set to 13:52 and a date of 03/10/2026. Next to this is French text that reads "En Suisse, il est illégal de posséder un seul cochon d'Inde car ces animaux ont besoin d'interaction sociale." (which translates to: "In Switzerland, it is illegal to own a single guinea pig because these animals need social interaction."). Below the time is a large blue panel with white text, "RC," which means "Rez-de-Chaussée" or ground floor, with a downward-pointing arrow and a small circle with a line through it. An illustration below the French text depicts three reddish-brown, white, and black guinea pigs grouped together over a bowl against an orange background, with a dark branch with leaves on the right.

I don’t think everyone realizes how bad things are for US science: For the fiscal year that just ended, the Trump regime withheld $1.4 billion from the National Science Foundation’s research budget, which is about 1/5 of its primary research budget.

"Police said the bicyclist was not wearing a helmet." Who cares? A bicycle helmet isn't designed to protect cyclists against cars. "At this time, speed, drugs or alcohol do not appear to be contributing factors in the collision, police said." Speed is absolutely a factor, to the 2nd power.
