If global warming was a real crisis, they'd be proposing a real solution. Like this:
If Greenland melted down completely, 88% of the excess water produced could be contained by flooding the uninhabited Qatarra Depression in northwest Egypt, producing thousands of miles of valuable lakefront property, generating electrical power as water flowed from the Medditerranean to the depression and potentially turning much of the surrounding Sahara Desert into arable land.
It took Greenland 18,000 years to accumulate as much ice as it has now. How long do you think it will take it to melt?
Salt water (which Greenland ice will be by the time it gets to the eastern Mediterranean) isn't much good for irrigating crops.
According to the GW kooks, a few months.
