It has been estimated that about 5.1 million excess deaths per year are associated with non-optimal temperatures. Of those, 4.6 million are associated with colder than optimum temperatures, and 0.5 million are associated with hotter than optimum temperatures.
Hilariously typical for someone who espouses knowing the facts and science to have not read any, or in this case, probably more typical of someone who doesn't really know how cold our planet really is. We're nearly six months into the year and my major city is just now leaving risk-to-human-life cold temperatures.
Also, if you care even a little about the science, check out the ClimateGPT program released recently - it can highlight where you're wrong about our environment. Yes, AGW is real and we're coming to understand it, but in terms of global impact, we are undergoing a massive greening event and global biome ranges are increasing. In other words, the slightly warmer weather and increased CO2 has been a boon to plants and animals. Of course, the people (poor and rich) who've gathered in our warmest climates already (also on coastlines), are the ones really damaged by AGW. Seems to rarely be the underprivileged we hear from there though, moreso wealthy people from California crying about needing to crank up their AC.
