Ever dipped your foot in a glacial stream? Pretty darn cold it is.
Now, imagine massive quantities of cold, fresh water pouring off the Greenland ice sheet as the sheet collapses. Must be a lot of cold water around Greenland. Not!
SST anomalies around Greenland are currently the highest in the world.
Freshwater is lower density than sea water and floats on top. If there was a lot of fresh meltwater coming off Greenland, SST anomalies would be far below normal – the opposite of what we are seeing.
Just a few years ago people were forecasting a European ice age due to this idea. But the Greenland meltdown just isn’t happening.
Richard Kerr of Science magazine reports on a presentation at the recent fall meeting of the American Geophysical Union in a News Focus article entitled: ‘Galloping Glaciers of Greenland Have Reined Themselves In’
Ice loss in Greenland has had some climatologists speculating that global warming might have brought on a scary new regime of wildly heightened ice loss and an ever-faster rise in sea level. But glaciologists reported at the American Geophysical Union meeting that Greenland ice’s Armageddon has come to an end.
