- tomjen3 5y agoBased on that, it would be a good thing and we should work to increase global warming so that our safety margin gets bigger.
- ceejayoz 5y agoIf "ice" and "no ice" were the only two possible scenarios, sure. Unfortunately, it's entirely possible to go too far in the other direction. https://en.wikipedia.org/wiki/Wet-bulb_temperature https://en.wikipedia.org/wiki/Wet-bulb_temperature > Even heat-adapted people cannot carry out normal outdoor activities past a wet-bulb temperature of 32 °C (90 °F), equivalent to a heat index of 55 °C (130 °F). The theoretical limit to human survival for more than a few hours in the shade, even with unlimited water, is 35 °C (95 °F) – theoretically equivalent to a heat index of 70 °C (160 °F), though the heat index does not go that high. > A heat wave in August 2015 saw temperatures of 48.6 °C (119.5 °F) and a dew point of 29.5 °C (85.1 °F) at Samawah, Iraq, and 114.8 °F (46.0 °C) with a dew point of 89.6 °F (32.0 °C) in Bandar-e Mahshahr, Iran. This implied wet-bulb temperatures of about 33.5 °C (92.3 °F) and 34.7 °C (94.5 °F) respectively. The government urged residents to stay out of the sun and drink plenty of water. Hit 35 °C wet bulb somewhere heavily populated like Bangladesh for a day and you're looking at significant casualties.

- scarmig 5y agoThe appropriate comparison: imagine you had NYC in Doggerland in 10000 BCE, and the ice age ended in ~100 years.
- Tepix 5y agoI don't think New York was there at the time.
