Rapid Destabilization Of Totten Glacier Adds Another 10 Feet Of Sea Level To WAIS Meltdown

#t=0

The latest “This is Not Cool” video is the third in a trilogy of very important, and sobering, pieces I’ve posted over the last year. I didn’t start with a trilogy in mind, but the developments of the last few months have been jarring and momentous.

Chris Mooney wrote recently in the Washington Post, “A hundred years from now, humans may remember 2014 as the year that we first learned that we may have irreversibly destabilized the great ice sheet of West Antarctica, and thus set in motion more than 10 feet of sea level rise.”. He added, “Meanwhile, 2015 could be the year of the double whammy — when we learned the same about one gigantic glacier of East Antarctica, which could set in motion roughly the same amount all over again.”

The decades-long unfolding of this story – that vast areas of ice once thought to be invulnerable on time scales meaningful to humans, may in fact already be in the process of disintegration – is one that that the vast majority of humanity still does not understand, and that the media has been unwilling to track. It’s a realization that, one top expert told us, even seasoned ice sheet veterans find “shattering”.

For this video I used in-person interviews from December’s AGU conference, as well as a skype chat with Jamin Greenbaum of the University of Texas, whose recent research on East Antarctic vulnerability has been widely reported. Jamin pointed me to some Australian research from the same area. There was a huge volume of material, not all of which made it into this video, but which I’ll be posting in coming weeks to flesh out the picture.
