Under current guidelines, the planet is on target to warm by 2 degrees Celsius in 2050 and by 4 degrees in 2100, triggering serious large-scale problems by the end of the century. “Drought, heat waves, forest fires — we are already seeing this,” says … Read more The Climate Change Facts You Need to Know

Small volcanic eruptions explain warming hiatus

Scientists have long known that volcanoes cool the atmosphere because of the sulfur dioxide that is expelled during eruptions. Droplets of sulfuric acid that form when the gas combines with oxygen in the upper atmosphere can persist for many months, reflecting sunlight away from Earth and lowering temperatures at the surface and in the lower … Read more Small volcanic eruptions explain warming hiatus

West Antarctic glacier loss appears unstoppable

A rapidly melting section of the West Antarctic Ice Sheet appears to be in irreversible decline, with nothing to stop the entire glacial basin from disappearing into the sea, according to researchers at UC Irvine and NASA. The new study presents multiple lines of evidence — incorporating 40 years of observations that six massive glaciers … Read more West Antarctic glacier loss appears unstoppable

Into the Wildfire

Researchers at Los Alamos National Laboratories and elsewhere are investigating other aspects of fire propagation, like how big fires create their own weather — a process that has contributed to some of the most devastating fires in recent years. The setup in the photo above is known as a “fire-whirl generator” and is used to … Read more Into the Wildfire
