Climate researchers have disproved the theory that roving Vikings including Erik the Red were able to settle on Greenland around AD 985 because the island was warmer at that time.
Climate change critics have long pointed to this as evidence that the current period of global warming is due to the natural climate patterns of the earth over millennia, and not because of human activity.

The new evidence comes as world leaders gather in Paris to discuss ways to tackle climate change. Read more: buffalonews.com
