Summer Arctic sea ice is going extinct 50% faster than predicted
By Philip Bump
In 2010, the European Union launched a satellite called CryoSat-2, with data analysis to be done by scientists at University College London (UCL). It had one task: determine the extent and thickness of sea ice. Previous satellites either couldnt gauge ice thickness or had trouble penetrating cloud cover. CryoSat-2 can do both.
It just got in under the wire.

Combining data from a predecessor to CryoSat (named, lamely, ICESat) with on-the-ground measurements, scientists calculated the amount of Arctic sea ice in winter 2004 at 17,000 cubic kilometers, and in summer, at 14,000. .....................(more)

I don't want to think we're toast, but...

I would like to be an optimist but I don't see any other negative feedback loop after we cross the Rubicon.

It would be nice if people with the money to blow through resources at will would stop doing so.

Having said that the melting of all the glaciers may alter plate tectonics enough to increase volcanic activity.

Obviously world leaders couldn't give a rip... and individuals intent on consuming as much as possible in their all-important (and tragically misguided) pursuit of happiness are too busy think of anything but themselves.

(58,403 posts)Now we got country and western on the bus
R and B, we got disco in eight tracks and cassettes in stereo
We've got rural scenes & magazines
We've got truckers on the CB
We've got Richard Pryor on the video
We got time to think of the ones we love
While the miles roll away
But the only time that seems too short
Is the time that we get to play
People you've got the power over what we do
You can sit there and wait
Or you can pull us through
