Hansen blows hot air up Parliament’s skirt.
From the transcript of Hansen’s testimony before the House of Commons:
Q3 Chair: To what extent is there consensus in the scientific community as to what constitutes dangerous climate change?
Professor Hansen: If you ask an authoritative scientific body-like our National Academy of Sciences or your Royal Society, or any of the geophysical unions or meteorological unions-there is a consensus that warming of 2°C or more would certainly be dangerous. There is not disagreement among the relevant scientific community. You can always find a few people who disagree, but in general there is consensus on that.
