Why the Arctic is Melting
Instead of cooling down – New research indicates that Arctic temperatures in the 1990s reached their warmest level of any decade in at least 2,000 years. In fact, the Arctic would be COOLING right now if it wasn’t for the greenhouse gas emissions that are overpowering natural climate patterns, such as reduction in sunspots.
When scientists used their computers to reconstruct summer temperatures across the Arctic over the last 2,000 years, decade by decade, they found that thousands of years of gradual Arctic cooling, related to natural changes in earth’s orbit, would continue today if not for emissions of carbon dioxide and other greenhouse gases.
