Narrow corridors of air loaded with moisture straight from the tropics may be driving a series of ice shelf collapses in the fastest-warming part of Antarctica, scientists have found.
Why it matters: Ice shelves act like doorstops, holding back the land-based ice behind them. When they are lost or weakened, inland ice can melt faster, raising sea levels worldwide.
After years of bleak projections, countries now have better than even odds of limiting global warming to at or below the Paris Agreement's 2°C temperature target, a new study finds.
Yes, but: This requires all national emissions reduction pledges to be fully met, which countries are not currently on course to do.
