Confidence in climate models projections relies on historical accuracy, robustness, and support by background knowledge. In the first part of the talk, I will show that model projections of transient global warming, land-sea warming contrast, Arctic amplification, and arctic sea ice melt have indeed largely come to pass since the predictions were first made in the 1960s and 1970s. In the second part of the talk, I will express disappointment in the fact that policymakers allowed the projected changes to emerge before even beginning to take appropriate action. I will conclude with the hope that diverse, youth-led, and science-based social movements can yet bring about emissions mitigation consistent with global climate goals. I will illustrate this optimistic scenario by implementing a crude policy feedback into a simple climate-economic model.
