Climate 101 is a Mashable series that answers provoking and salient questions about Earth’s warming climate.
It's speeding up.
Antarctica's Pine Island Glacier, already the biggest source of sea level rise from the ice-clad continent, has started purging more ice than ever observed (from it) into the ocean.
In research recently published in the journal Science Advances, glacier experts found Pine Island — which holds some 180 trillion tons of ice — lost big chunks of ice into the sea over the past few years (2017-2020), and the glacier picked up its pace. This means Pine Island continues to recede, weaken, and expel more ice into the ocean, with the potential to add much more sea level rise to the planet's already problematic sea level woes. (Earth's sea levels have already risen by some eight to nine inches since 1880, and they're now accelerating.) Read more...
