Sea Levels May Rise More Rapidly Due To Greenland Ice Melt
An anonymous reader quotes a report from The Guardian: Rising sea levels could become overwhelming sooner than previously believed, according to the authors of the most comprehensive study yet of the accelerating ice melt in Greenland. Run-off from this vast northern ice sheet -- currently the biggest single source of meltwater adding to the volume of the world's oceans -- is 50% higher than pre-industrial levels and increasing exponentially as a result of manmade global warming, says the paper, published in Nature on Wednesday. Almost all of the increase has occurred in the past two decades -- a jolt upwards after several centuries of relative stability. This suggests the ice sheet becomes more sensitive as temperatures go up.
The researchers used ice core data from three locations to build the first multi-century record of temperature, surface melt and run-off in Greenland. Going back 339 years, they found the first sign of meltwater increase began along with the industrial revolution in the mid-1800s. The trend remained within the natural variation until the 1990s, since when it has spiked far outside of the usual nine- to 13-year cycles.

May rise? Let me know when we ACTUALLY see some sea rise. Then we can talk about 75% taxers and regulations that basically make everyone a slave to the government, you know like in Europe.
Once upon I time, I thought it was a legitimate concern. But they've Chicken Littled it way beyond anything I have patience for at this point.
You should improve your critical thinking skills. Whether it is a "legitimate concern" or not, is completely unrelated to whether "they" are Chicken Littling it.
Doesn't matter.
If you want to convince people of things (which some of us call "democracy", and think it's the least worst form of government), then chicken littling for 30 or 40 years (oh, and calling them "stupid", "deniers", etc.) is not the way to do it.
You will numb people to what you are saying.
As a person of a somewhat older generation I have seen the earth a lot longer than you. And I can tell you, nothing has changed much. Nothing out of the ordinary anyway. Ice has always melded. Storms were always there. Bush fires happened long before you were born. Earthquakes happened long before you were born. Hot and cold winters have been there since forever.
Climate doesn't give a damn about us humans, it changes as it pleases. No taxes or windmills are going to change a damn bit about that. Climate doesn't care if 97% of scientists tell us it's a disaster, as science isn't democratic. It's facts. And the facts are that nothing has changed much.
