DNA reveals Greenland's lush past
Armies of insects once crawled through lush forests in a region of Greenland now covered by more than 2,000m of ice.
DNA extracted from ice cores shows that moths and butterflies were living in forests of spruce and pine in the area between 450,000 and 800,000 years ago.
Researchers writing in Science magazine say the specimens could represent the oldest pure DNA samples ever obtained.
The ice cores also suggest that the ice sheet is more resistant to warming than previously thought, the scientists say.

Slowly and with time the truth about global warming will come out.
