Have you ever looked at a globe or map – Greenland is enormous, and it only has about 56,000 people. Right after WWII the U.S. offered to buy Greenland from Denmark for $100 million, but no deal. We could have had 51 states!

Between 1989 and 1993, U.S. and European climate researchers drilled into the summit of Greenland's ice sheet, obtaining a pair of 3 km (1.9 mi) long ice cores. Analysis of the layering and chemical composition of the cores has provided a revolutionary new record of climate change in the Northern Hemisphere going back about 100,000 years, and illustrated that the world's weather and temperature have often shifted rapidly from one seemingly stable state to another, with worldwide consequences.[46] The glaciers of Greenland are also contributing to a rise in the global sea level at a faster rate than was previously believed.[47] Between 1991 and 2004, monitoring of the weather at one location (Swiss Camp) showed that the average winter temperature had risen almost 6 °C (11 °F).[48] Other research has shown that higher snowfalls from the North Atlantic oscillation caused the interior of the ice cap to thicken by an average of 6 cm or 2.36 in/yr between 1994 and 2005.[49]
