IPCC 1.5°C Report: Economic Damages
from Climate Change

Global economic damages of climate change are projected to be smaller under warming of 1.5°C than 2°C in 2100 (Warren et al., 2018c).

The mean net present value of the costs of damages from warming in 2100 for 1.5°C and. 2°C (including costs associated with climate change-induced market and non-market impacts, impacts due to sea level rise, and impacts associated with large-scale discontinuities) are $54 and $69 trillion, respectively, relative to 1961–1990.

Values of the social cost of carbon vary when tipping points are included. The social cost of carbon in the default setting of the Dynamic Integrated Climate-Economy (DICE) model increases from $15 tCO2 to $116 when large-scale singularities or ‘tipping elements’ are incorporated . These calculations excluded the large health co-benefits that accrue when greenhouse gas emissions are reduced

The economic damages of climate change in the USA are projected to be large , the USA stands to lose -0.1 to 1.7% of the Gross Domestic Product (GDP) at 1.5°C warming.

The report shows with certainty that 1.5C is globally disastrous but 2C is total planetary catastrophe ​

MITIGATION (best-case P1)
  • ​Immediate (2020) rapid decline in global emissions
  • By 2030 a 50% drop emissions  
  • By 2050 near zero Fossil fuel energy
