Here is his *entire* reasoning for why we should commit trillions every year: The high-pitched argument for a parallel to WWII rests entirely on the following arguments (which are not good)pic.twitter.com/XGsEFNe1Le

Here is Stiglitz' *only* concrete number. There is no reference, but many other ill-informed commentators have used this $350bn estimate from GAO for the cost of extreme weather to US government over past decade, meaning 1.8% of GDP https://www.gao.gov/assets/690/687466.pdf …pic.twitter.com/sbAR3asvw4

This is ridiculous. Not only is $350bn a cost over ten years (so 0.18% GDP per year, and not 2%, as Stiglitz tries to claim), but it is also the costs of *all* extreme weather. Does Stiglitz believe there is no bad weather without climate change? No bad weather in past?pic.twitter.com/opDe0QycKs

Even if Stiglitz had used the more appropriate measure (e.g. Aon) of $88bn/yr in weather-related damages over past decade, that is 0.48% GDP/yr, and still it is *all* weather damage, most of which obviously would remain without climate change http://thoughtleadership.aonbenfield.com/Documents/20190122-ab-if-annual-weather-climate-report-2018.pdf …pic.twitter.com/VuXtDu2rFa

Indeed, we know that most damage comes from hurricanes, and although cost have dramatically increased, this is because of more people (Florida coastal population increased 67x since 1900, US 4.3x) that are richer When correcting for that, no increase https://journals.ametsoc.org/doi/full/10.1175/BAMS-D-17-0184.1 …pic.twitter.com/jQzqvgcb2C

Indeed, this is also true globally, where weather disaster costs are *not* increasing (seemingly slightly decreasing) in share of GDP update of https://www.tandfonline.com/doi/full/10.1080/17477891.2018.1540343 …pic.twitter.com/rIHwFkLASK

Stiglitz other argument is health costs, but unfortunately, he couldn't really be bothered to find any arguments. They are apparently still "being tabulated", but 'trust me, they will run into tens of billions of dollars.'pic.twitter.com/4MlsILXC3p

Well, if it is okay with Stiglitz, I think data is better Here deaths from cold and heat in the US — similar to most other countries. Heat deaths are small and declining (because richer people can afford aircon) whereas cold deaths are big and increasing https://www.sciencedirect.com/science/article/pii/S0160412017310346 …pic.twitter.com/p47WxeVTlc
