Sunday set: Meltdown

Global sea ice at record low

It’s hard to really get your head around what it means that the Arctic ice cap is literally melting away, and perhaps even harder to imagine that massive tracts of Antarctic ice are also giving way to global warming. But the science is pretty clear: During other epochs of Earth’s geological history, at times when there were similar global temperatures and about the same amount of CO2 in the atmosphere, so much ice melted that sea level was at least 20 feet higher than today. Today’s Earth — our Earth — seems to be responding the same way. For all of December, the extent of global sea ice has set record lows every single day.  The Arctic meltdown is well documented by more than 100 years of data. Around the South Pole, more and more studies are showing warm layers of water melting large coastal slabs of ice that hold back the almost unimaginable masses of ice on the Antarctic continent. The images in this set are just snapshots, but what’s happening out there is very real. Take #climateaction now.
