In the latest paleoclimate research published this week, climate scientists have been able to use a new source of proxy data to lengthen the known length of the Atlantic sea surface temperature from 100 years to 2,900 years using lake sediments from Sawtooth Lake in the Canadian High Arctic. The research shows that the last ten years have been the warmest in their entire record.
