In widely reported findings, UGA climatologists and NASA independently confirm that during several days this month, nearly the entire ice sheet of Greenland experienced some degree of melting on its surface.
On average, about half of the surface of Greenland's ice sheet naturally melts in the summer. The new data—from three different satellites—show that an estimated 97 percent of the ice sheet surface thawed at some point in mid-July.
"This is the first time we have witnessed almost all of the ice sheet melt in the three decades of satellite data," said Thomas Mote,...
And speaking of Dr. Shepherd, he was quoted on the New York Times Green blog this weekend, per how he answers questions related to the changing global climate:
Climate scientists, like the rest of us, have friends and relatives who wonder what is happening. So I asked the scientists: When you see your extended family over Thanksgiving or Christmas and they ask about the weather, what do you tell them?
“My answer on that has evolved,” replied one, J. Marshall Shepherd. He’s the head of atmospheric sciences at the University of Georgia and the president-elect of the American...
Lee Shearer of the Athens Banner Herald reports on research by Franklin faculty on the recent drought:
But measured by its impact on people in the four counties served by the Bear Creek Reservoir, and how much it depleted water in area rivers, it was the worst on record, they say in an article published this month in the Journal of the American Water Resources Association.
“The smoking gun is pointing at population increases,” said one of the paper’s authors, UGA geography professor John Knox.
The paper’s authors also include former UGA geography graduate...
I watched this NOVA presentation over the holidays, and while you might think that nothing could move as slow as a glacier, they are unfortunately not shifting all that slowly. The scientists on the program were able to measure movement that, while imperceptible to the naked eye, equaled about 130 feet per day. That is amazing. And alarming.
Researchers at the American Geophysical Union annual meeting in San Francisco reported last month that rising sea levels over the next century may be much greater than even they had anticipated:
