Melting Arctic ice is now pouring 14,000 tons of water per second into the ocean, scientists find

A new survey finds that the region has contributed almost an inch to rising seas since 1971.

A new scientific survey (1) has found that the glaciers of the Arctic are the world's biggest contributors to rising seas, shedding ice at an accelerating rate that now adds well over a millimeter to the level of the ocean every year.

That is considerably more ice melt than Antarctica is contributing, even though the Antarctic contains far more ice. Still, driven by glacier clusters in Alaska, Canada and Russia and the vast ice sheet of Greenland, the fast-warming Arctic is outstripping the entire ice continent to the south -- for now.

However, the biggest problem is that both ice regions appear to be accelerating their losses simultaneously -- suggesting that we could be in for an even faster rate of sea-level rise in future decades. Seas are rising by about three millimeters each year, according to NASA. That's mainly driven by the Arctic contribution, the Antarctic and a third major factor -- that ocean water naturally expands as it warms.

For Arctic ice loss, "the rate has tripled since 1986," said Jason Box, first author of the new study and a scientist at the Geological Survey of Denmark and Greenland. "So it clearly shows an acceleration of the sea-level contribution."

Came here to say that. These kinds of stats need to be in relatable terms so a layperson can easily grasp, particularly when you're trying to tell the story in 140 characters.

3. When the crops eventualy fail, eat the deniers first

They have blood on their hands. Like the tobacco companies, they knew about the problem long before the public did.

5. And that fresh water....

pooling in the ocean....

is changing the gulf stream current...

is changing high and low pressure systems that develop over the ocean

which is changing the jet stream

which is causing global changes in climate.

8. Count down to the Atlantic Conveyor shutting down

We will not be able to deal with climate change until we deal with capitalism first.

13. In that case you can save a few words

"We will not be able to deal with climate change."

As I've been saying for over a decade. But hey, what does a fatalistic defeatist like me know?

10. Relatable terms help people understand.

Except perhaps for the hardcore deniers who will still chant Oh yeah prove it, its a left wing hoax.

12. Going to be really interesting to see the effect of the weight change...

on the movement of the tectonic plates.

I would not want to live near any major faults or subduction zones over the next 100 years.
