Apparently that's how much of the world's fresh water is tied up in the Greenland ice sheets. And current measurements are putting them in the ocean a lot faster than they used to be travelling. According to an article in the Guardian, "Helheim, an enormous tower of ice that calves into Sermilik Fjord, used to move at 7km (4.4 miles) a year. In 2005, in less than a year, it speeded up to nearly 12km a year." Kangerdlugssuaq, another glacier, is now moving at an inch (24 mm) every minute, making its motion visible to the naked eye.
The rate of calving off the Greenland glaciers has risen so dramatically that it seems that the calves are now big enough to generate seismic events transmitted through the earth, and these events actually help speed up the glaciers.
The world response to global warming has, so far, been (to quote the Guardian) "all mouth and no trousers." Which is why they've launched the 10:10 campaign--a campaign to have people pledge to reduce their carbon footprint by 10% in 2010.This would seem to be a no-brainer, as it is only a matter of picking the low hanging fruit in our lives. Some of us have already taken this step, and from here on out the choices become more difficult and require more governmental involvement, but still, we can and should be out in front of our elected officials on this one.
Not everyone is happy, of course. There is a certain amount of anger over the EU-mandated phase out of the incandescent light bulb. But most people are on-side, and really just need a gentle pointing in the right direction to get going. So lets get on board, even those of us well into the change. Let's drop our CO² emissions by another 10% in 2010.
