James Hansen - Two views

The BBC describe NASA's Professor James Hansen thus:

'Prof James Hansen, the Nasa scientist who has done perhaps more than any other academic down the years to raise the spectre of catastrophic climate change. '

Scott Pelley on 60 Minutes introduced Hansen as “NASA’s top climate scientist, credited with the earliest and most accurate projections on climate change.”

Peter F at Watts Up With That recalls something interesting:
'I recall Hansen’s 1988 testimony before Congress in which he predicted a warmer climate by 1.2°C in twenty years. Here in 2009, the global average is only 0.17 to 0.22°C warmer than the 20th Century benchmark. He then had the audacity to publish a paper with himself as the lead author extolling the virtues of the accuracy of his 1988 projections. Looking back, none of his three scenarios came even within 50% of being accurate, yet the ya-hoos over at RealClimate.org insist Hansen was and is spot on.'

The truth is out there...
