The West Antarctic Ice Sheet will continue to increase its rate of melting over the rest of the century, no matter how much we reduce fossil fuel use, according to new research.
A substantial acceleration in ice melting likely cannot now be avoided, which implies that Antarctica's contribution to sea level rise could increase rapidly over the coming decades.Scientists ran simulations on the UK's national supercomputer to investigate ocean-driven melting of the West Antarctic Ice Sheet: how much is unavoidable and must be adapted to, and how much melting the international community still has control over through reduction of greenhouse gas emissions.
Around the world millions of people live near the coast and these communities will be greatly impacted by sea level rise. A better understanding of the future changes will allow policymakers to plan ahead and adapt more readily."It looks like we've lost control of melting of the West Antarctic Ice Sheet. If we wanted to preserve it in its historical state, we would have needed action on climate change decades ago.
This study presents sobering future projections of Amundsen Sea ice-shelf melting but does not undermine the importance of mitigation in limiting the impacts of climate change. Greenland may be best known for its enormous continental scale ice sheet that soars up to 3,000 meters above sea level, whose rapid melting is a leading contributor to global sea level rise. But ...

The West Antarctic ice sheet faces ‘unavoidable’ melting, a warning for sea level riseRegardless of how aggressively humans act to reduce fossil fuel emissions, waters around some of Antarctica’s glaciers are forecast to warm at a pace three times faster than they have in the past, a new study says.

What will happen to the Greenland ice sheet if we miss our global warming targetsIt's hard to overstate how crucial Greenland, and its kilometers-thick ice layer, is to climate change. If all that ice melted, the sea would rise by about seven meters—the height of a house.
