Our new @NatureClimate paper just out! State-of-the-art estimates of economic impacts of climate change show that benefits of #ClimateAction outweigh the mitigation costs by a factor of 1.5 to 3.9 ➡️strong economic validation of #ParisAgreement 🔗 rdcu.be/c8jSK 1/7 
We combined climate impacts of
🔴agriculture,
🟠sea-level rise,
🟡river floods,
🟢labour productivity,
🔵energy supply/demand,
🟣fishery,
🟤forestry and
⚫️road transportation
and transform this in financial costs. But not: ❌biodiversity loss❌health❌tipping points 2/7

For a 3°C scenario (RCP6.0, roughly current trend/baseline), economic impacts are 10-12% of GDP, with high regional differences. Even higher if sea-level rise adaptation is not optimal. 3/7
For <2°C (RCP2.6), impacts much lower, but still about 2% of GDP. 4/7
Combined with mitigation costs: #costbenefit analysis: optimal temperature around 1.8°C across the three IAMs combined➡️uncertainty of damage function also important (middle column = medium). AND: underestimate of damages, so optimal target likely even lower (towards 1.5°C) 5/7
For this optimal scenario, the benefits of reduced damages are much larger than the corresponding mitigation costs: 1.5 to 3.9 times larger. And since no #biodiversity etc, benefits in reality even larger. 6/7
With @DetlefvanVuuren @JohannesEmm @lolow225 and more. @UniUtrecht @UUCopernicus @nlenvironagency @EIEEorg PIK, especially Francesco, thanks for the great collaboration in the @COACCH_EU project! And thanks @JKikstra and others for useful review comments. 7/7
Very important in combination with latest #IPCC findings saying that immediate #climateaction is needed.
