How Fast Can Ice Melt? Understanding New Sea Level Estimates
April 11, 2016
Decided to put together a video intro to the advancing science of ice sheet dynamics, which has been in the news recently.
New paper by Deconto et al has added more realistic simulations of “cliff failure” to models of Antarctic ice loss, and come up with more rapid sea level scenarios.
Above, Jason Box’s very valuable discussion about accelerators of Greenland ice melt, which is an analogue for what we could see, starting on the Antarctic Peninsula, in the south.
Here, James Hansen clearly summarizes the findings of his most recent, widely publicized paper.
Leading up to these, a large body of research had made this clear – Sea level was much higher in recent epochs when greenhouse gases were at current levels.
How fast do those sea levels respond to a changing atmosphere?
And finally, John Cook and I were left with jaws on the floor after the stunning interview with Eric Rignot in 2014.
Compare the sense of urgency above, with the calmer demeanor of just 2 years before.
