LiveScience: In the last 10,000 years, the Greenland Ice Sheet shrank to its smallest size around 3,000 to 5,000 years ago, when ocean temperatures were also quite high, a new study suggests.
The finding, published Nov. 22 in the journal Geology, suggests that ocean temperatures, not atmospheric temperatures, could be a critical factor in melting ice sheets in current global warming scenarios. Understanding the reaction ice sheets like the ones covering Greenland and Antarctica will have to climate change...
