The UN Climate Panel tells us that climate impacts by 2070s are equal to average reduction in income of 0.2-2% Equivalent to one recession in the next half-century https://archive.ipcc.ch/pdf/assessment-report/ar5/wg2/ar5_wgII_spm_en.pdf …pic.twitter.com/4gKoUNaZo9

UN Climate Panel's estimate of damage across temperatures (updated by Climate Nobel Laureate Nordhaus) shows moderate costs — likely about 2-4% of GDP by 2100, even if we do nothing https://www.nber.org/reporter/2017number3/nordhaus.html …pic.twitter.com/bon0GmHr02

Even the new 1.5°C UN Climate Panel report pointed out that if we do nothing, a 3.66°C temperature increase will cost 2.6% of global GDP https://www.ipcc.ch/sr15/ , page 256pic.twitter.com/i6Q2C1gsmS

And by 2100, the average person in the world will make 450% of what (s)he does in 2020. The average person in the non-OECD will make 600% of today (middle-of-road SSP2) Compare this to climate impacts of 2.6% or 4% even without policies https://www.sciencedirect.com/science/article/pii/S0959378016300681?via%3Dihub …pic.twitter.com/Kt1ICvF0I4

Compare this to the cost of going carbon neutral in the cheapest way by 2050 (so effectively, and rather late, given current breathless promises) New Zealand gov't requested official cost estimate: 16% of GDP (https://www.mfe.govt.nz/sites/default/files/media/Climate%20Change/NZIER%20report%20-%20Economic%20impact%20analysis%20of%202050%20emissions%20targets%20-%20FINAL.pdf … (p16, avg of ZNE targets)pic.twitter.com/WzHko0PbOc
