Antarctica ice melt has accelerated by 280% in the last 4 decades

According to a study led by Eric Rignot from the University of California at Irvine, which looked at details of ice and snow from the entire continent of Antarctica since 1979, Antarctica's crucial ice sheet has been melting for the entire 39 year period, but that is just the tip of the iceberg, so to speak.

"Antarctica is melting away," Rignot told CNN, "not just in a couple of places."

The research, published in the Proceedings of the National Academy of Sciences, found that the rate of that ice loss has not been consistent, with ice disappearing faster in each successive decade. Ice loss in Antarctica has increased from 40 gigatons (a gigaton is one billion tons) per year from 1979-90 all the way up to 252 gigatons per year from 2009-17, a 6-fold increase.

And that melt-rate has been accelerating in the most recent decades, up 280% in the second half of the nearly 40 years compared to the first half, Rignot and his colleagues calculated.

Sometimes it melts and sometimes it freezes.  It's all up to the Sun.

So what?

[wvit1001]

what's up that the sun's melting the ice faster now then wavy?   is the sun getting hotter or are we closer to it or what?

[dont-blameme]

It's been going on since time began, so do you think man has something to do with it wvit?

[wvit1001]

so why's it happening now blammey? 

[dont-blameme]

It's been happening since time began warm periods and cool periods so has man caused that wvit?

There should be copy and paste out there explaining all that wvit

[wvit1001]

so you can't say why you think it's getting warmer now?   

[dont-blameme]

It's your story wvit you tell it like you always do spiked with bullshit and man caused it all!

Good.  More land for people.

[wvit1001]

well except that it's mostly rock and extremely cold and dry dan.
