A new supercomputer named after a winner of the Nobel Prize in chemistry will help power artificial intelligence technology and scientific discoveries from a perch in the hills above the University of California, Berkeley, federal officials said Thursday.

The federal government is investing in machines that suck giant amounts of carbon dioxide out of the air in the hopes of reducing damage from climate change.

Scientists say they have been able to spark a fusion reaction that briefly sustained itself, a significant milestone on the long path to fusion power.

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.
