In 1988, NASA’s James Hansen published these three forecasts of global warming doom :
At his Congressional testimony that year he said that the uppermost curve, Scenario A, is “Business As Usual.” Scenario C assumed that no new CO2 was added to the atmosphere after the year 2000
So far, temperatures (normalized to 1980) are below Hansen’s zero CO2 growth Scenario C.
Government experts are now saying that the global warming hiatus may continue for another decade. I plotted that below.
That would put temperatures almost 1C below Hansen’s BAU Scenario A. The data indicates that climate sensitivity to CO2 is essentially zero, meaning that James Hansen’s global warming crisis is non-existent. It’s dead, Jim.
