“We see a tipping point occurring right before our eyes,” Hansen told the AP before the luncheon. “The Arctic is the first tipping point and it’s occurring exactly the way we said it would.”
Hansen, echoing work by other scientists, said that in five to 10 years, the Arctic will be free of sea ice in the summer.
Ed Markey, D-Mass., committee chairman, said, “Dr. Hansen was right. Twenty years later, we recognize him as a climate prophet.”
