Research Highlight: Loss of Arctic's Reflective Sea Ice Will Advance Global Warming by 25 Years
Fast mitigation may still avoid complete loss of sea ice
Losing the remaining Arctic sea ice and its ability to reflect incoming solar energy back to space would be equivalent to adding one trillion tons of CO2 to the atmosphere, on top of the 2.4 trillion tons emitted since the Industrial Age, according to current and former researchers from Scripps Institution of Oceanography at the University of California San Diego.
Half of Antarctic ice shelves could collapse in a flash, thanks to warming
Antarctic ice shelves can disappear astonishingly fast — sometimes in minutes or hours — as meltwater surges through cracks in their surface. And as the atmosphere warms, this phenomenon may become more commonplace; at least half of the ice shelves on the continent are vulnerable to this process, a new study suggests.
The new study, published today (Aug. 26) in the journal Nature, suggests that about 50% to 70% of ice shelves that hold Antarctic glaciers in place could become weak and potentially collapse with surges of meltwater.

Though the researchers don't have a time frame yet, some scientists predict that climate change may drive massive hydrofracturing events within a matter of decades, according to a 2015 report in the journal Earth and Planetary Science Letters.
