BOULDER, Colo., Oct. 24 (UPI) -- Geologists say a study of temperatures in the Canadian arctic shows the last 100 years were warmer than any other century in at least the past 44,000 years.
The study, led by University of Colorado-Boulder geological sciences Professor Gifford Miller, used dead moss clumps emerging from receding ice caps on Canada's Baffin Island as tiny clocks, with radiocarbon dating showing they had not been exposed to the elements by ice melt since at least 44,000 to 51,000 years ago.
