Large potential reduction in economic damages under UN mitigation targets: Nature IJS

"International climate change agreements typically specify global warming thresholds as policy targets¹, but the relative economic benefits of achieving these temperature targets remain poorly understood^2,3. 

Uncertainties include the spatial pattern of temperature change, how global and regional economic output will respond to these changes in temperature, and the willingness of societies to trade present for future consumption. 

Here we combine historical evidence⁴ with national-level climate⁵ and socioeconomic⁶ projections to quantify the economic damages associated with the United Nations (UN) targets of 1.5 °C and 2 °C global warming, and those associated with current UN national-level mitigation commitments (which together approach 3 °C warming⁷)."
