Thwaites Glacier Is Melting Faster Than Scientists Thought


Listen
/
One of the largest glaciers in Antarctica is melting faster than previously known, according to new research published this month.
For the first time ever, scientists sent an unmanned submarine underneath the Thwaites Glacier, a massive ice sheet that flows out over West Antarctica’s Pine Island Bay. The team found warm currents of ocean water are lapping away at the glacier’s tongue.
That’s concerning news because the glacier contains enough freshwater to significantly raise global sea levels if it collapses. The research was published this month in the journal “Science Advances.”

Examining the impact of climate change on Siberia's stores of permafrost


Credit: Sebastian Breitenbach
Northumbria University is to play a leading role in a major study to assess the long-term impact of global warming on Siberia s thawing permafrost.
Permafrost is frozen ground that stores vast amounts of fossil carbon. Given that permafrost holds twice as much carbon as the atmosphere, and that almost a quarter of the Northern Hemisphere is covered in permafrost, this frozen land plays an essential role in stabilizing climate change.
Thawing permafrost is considered one of the key climate tipping elements that would lead to long-term irreversible changes to global climate. However, today s warming global temperatures mean permafrost is beginning to thaw and release greenhouse gases into the atmosphere. ....
