Do nothing costs $134tr
Do smart tax: costs $20tr, reduce climate damages $50tr = $30tr benefit
Do more (most campaigners): climate costs decline, policy costs increase much more, net loss $40tr+ pic.twitter.com/CbgZTeWLRj— Bjorn Lomborg (@BjornLomborg) January 27, 2019

And policies trying to reach 2.5°C (or even lower) will have *much* higher costs than benefitshttps://t.co/IvDSlz7dDk pic.twitter.com/V354uofxmF— Bjorn Lomborg (@BjornLomborg) January 27, 2019
