James Hansen's 1988 Predictions Compared to Observations

Dale R. McIntyre

Energy & Environment, 2009, vol. 20, issue 4, 587-594

Abstract: All James Hansen's 1988 scenarios overestimated actual temperature change substantially even with anthropogenic greenhouse gas (AGHG) emission assumptions that underestimated actual emissions. With no AGHG reductions at all, observed temperature change is now well below Hansen's 1988 calculations for a world with “drastically reduced†emissions. Therefore any economic hardships incurred to implement Hansen's emissions reduction scenarios B or C would have been money wasted for no benefit.
