A 91爆料 scientist has proposed an experiment to test cloud brightening, a geoengineering concept that alters clouds in an effort to counter global warming.

Changes in the speed that ice travels in more than 200 outlet glaciers indicates that Greenland’s contribution to rising sea level in the 21st century might be significantly less than the upper limits some scientists thought possible, a new study shows.

A grant to the 91爆料 from the Gordon and Betty Moore Foundation could pave the way for a system to provide a warning seconds to minutes in advance of a major offshore earthquake in the Northwest.

Relatively accurate predictions for summer sea ice extent in the Arctic can be made the previous autumn, but forecasting more than five years into the future requires understanding of the impact of climate trends on the ice pack.
When Steve Malone retired earlier this month, he could take satisfaction in the great strides that have been made in forecasting volcanic eruptions, particularly in the Pacific Northwest.
Steve Malone began studying Mount St. Helens in 1973. He didn’t know that just seven years later he would be tracking swarms of earthquakes signaling that the mountain was about to blow its top.
