"However, as we will see in this post, despite these doubts, the global warming projections in Hansen et al. (1981), based on the human-caused global warming theory, were uncannily accurate."



Figure 5: Hansen et al. (1981) global warming projections under a scenario of high energy growth (4% per year from 1980 to 2020) (red) and slow energy growth (2% per year from 1980 to 2020) (blue) vs. observations from GISTEMP with a 2nd-order polynomial fit (black). Actual energy growth has been between the two Hansen scenarios at approximately 3% per year. Baseline is 1971-1991.

Figure 1: Various best estimate global temperature predictions evaluated in the 'Lessons from Past Climate Predictions' series vs. GISTEMP (red). The warmer colors are generally mainstream climate science predictions, while the cooler colors are generally "skeptic" predictions.
