President Biden has promised to spend $500 billion each year on climate — about 13 percent of the entire federal revenue. The European Union will spend 25 percent of its budget on climate. Most rich countries now promise to go carbon-neutral by mid-century. Shockingly, only one country has made a serious, independent estimate of the cost: New Zealand found it would optimistically cost 16 percent of its GDP by then, equivalent …

But the mechanisms are different. A greenhouse stays warm by preventing warm air from escaping. In other words, it blocks convection. The atmosphere keeps the planet warm by preventing (some wavelengths of) infra-red radiation from escaping. The “greenhouse effect” is really the result of many layers of air, each absorbing infra-red from the …

I’ve purchased some very strong hip waders to prepare for the events. For those who don’t already know, sturdy hip waders are required when wading into sewage. I’ve also taken a quick look at the CMIP6 model output that has been posted to the KNMI Climate Explorer to date. I thought I’d share some of what I found. Figure 1. The CMIP6 13-member model ensemble from the KNMI Climate …
