Hansen vs Lindzen

Comparison of the observed GISTEMP temperature record (black) with temperature predictions from Dr. James Hansen's 1988 modeling study (red), and with our reconstructed temperature prediction by "skeptic" climate scientist Dr. Richard Lindzen based on statements from his talk at MIT in 1989 (blue). Hansen's Scenario B has been adjusted to reflect the actual observed greenhouse gas concentrations since 1988. Lindzen's statements of low climate sensitivity were used to reconstruct what his temperature prediction might have looked like as described here. Dr. Hansen's global temperature changes predicted in 1988 have proven quite accurate.
