Hansen just released this graph
Compare that to his 1988 forecast
The image below overlays Hansen’s current temperature graph on his 1988 forecast, normalized to the 1960s and 1970s. Note that temperatures are running well below Scenario C. Scenario C assumed that no more CO2 is added to the atmosphere after the year 2000.
scenario C assumes a rapid curtailment of trace gas emissions such that the net climate forcing ceases to increase after the year 2000.
Hansen has thus proven that man-made CO2 has little or no impact on the climate. Why is this scam continuing?
