Underwater Robot Reveals Hidden Base of Antarctica’s ‘Doomsday’ Glacier

sciencehabit shares a report from Science Magazine: Using a robot dropped through a 700-meter hole in the ice, scientists stationed on Antarctica’s Thwaites Glacier have captured the first video of the glacier’s grounding line, the mysterious boundary where ice meets land and where warm ocean water could be slowly melting the glacier’s base — putting it at risk of collapse (above)….

Air-Traffic Control Is in the Midst of a Major Change

Shift from radar to GPS should make tracking faster and more accurate, allowing more planes in the air. From a report: Since World War II, air-traffic controllers have used radar to keep track of aircraft. But as of Jan. 1, most planes and helicopters flying in the U.S. must be equipped with transponders that allow their movements to be traced with…

World’s Highest and India’s Largest Gamma-Ray Telescope To Go Live in Ladakh this Year

India’s largest and the world’s highest gamma-ray telescope is set to go live later this year, aiming to provide a new window into distant stars and galaxies in the universe. From a report: The Major Atmospheric Cherenkov Experiment Telescope (MACE) in Hanle, Ladakh, is placed at an altitude of 4,300 metres above sea level. It is the world’s second-largest, ground-based gamma-ray…

Antarctica’s doomsday glacier is melting. Can we save it in time?

A massive research effort is under way to understand Antarctica’s Thwaites glacier before it is too late. If it collapses, it could trigger catastrophic sea level rise, putting London and New York at risk Source: https://www.newscientist.com/article/mg24532650-900-antarcticas-doomsday-glacier-is-melting-can-we-save-it-in-time/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

Sea levels in Bangladesh could rise twice as much as predicted

Even if the world takes ambitious action on climate change, Bangladesh faces twice as much sea level rise as previously thought because of land subsidence Source: https://www.newscientist.com/article/2229118-sea-levels-in-bangladesh-could-rise-twice-as-much-as-predicted/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
