Enormous Aquifer Discovered Under Greenland Ice Sheet

From NASA, I had to laugh at this statement: The water in the aquifer has the potential to raise global sea level by 0.016 inches (0.4 mm). That’s assuming it can get out sometime in the distant future. Greenland’s topography … Continue reading

Climate Craziness of the week – with the physical signature of UHI staring them right in the face, Mann & Borenstein go with their ‘gut’ instincts

Some people wonder if Michael Mann is simply an activist masquerading as a scientist, this lends credence to that idea. I wonder if Dr. Mann has ever visited weather stations in China to understand what is going on there? I … Continue reading
