Lying with Statistics: The National Climate Assessment Falsely Hypes Ice Loss in Greenland and Antarctica

by E. Calvin Beisner and J.C. Keister How fast are Greenland and Antarctica losing ice? If you trust the National Climate Assessment (NCA), you’ll think, “Very fast!” And that’s intentional. The aim is to provoke fear so the American public … Continue reading

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
