Humans live from -50C to +40C, but two more degrees will kill us. Panic now.

Humans can adapt to live in locations where the monthly average is over 40°C, and as low as -50°C. That’s a 90°C range. The world has warmed by 0.9°C in 100 years (or less, depending on adjustments). This warming was so dangerous that global population only expanded from 1.7 to 7 billion.

Now, if the IPCC are right, we might heat up by another half a degree by 2100 — shifting those extremes from -49°C up to 41°C.

Prof. Andy Pitman, one of Australia’s leading climate scientists, responds to this risk with all the usual careful analysis we’ve come to expect from mainstream climate experts. Here’s another “children won’t know what snow is” type of Global Panic quote:

“I expect by 2050 … people just don’t go outside,”

– Professor Andy Pitman, director of the ARC Centre of Excellence for Climate System Science at UNSW.

So that’s the end of golf, surfing, and picnics then. Somewhat confusingly, he also said (in the same interview) that we won’t necessarily notice that extra warmth: “… because humans acclimatise to heat quite quickly”. This is what 95% certainty looks like in 2015, ladies and gentlemen — abject panic and nothing to see here, both at the same time… journalist Lucy Cormack swallows it all, trained by the Sydney Morning Herald to ignore wild claims and bizarre contradictions.

The hottest inhabited places on Earth

There is a lot of competition for the “hottest” town on Earth.

Marble Bar, Western Australia

Marble Bar, Western Australia

Dallol, Ethiopia has an average July monthly high of 45.6°C (114F), so it is usually top of the “hottest inhabited location lists”. But  is practically a ghost town so it doesn’t quite count, though miners lived there from 1960-1966 and the 45°C record heat was recorded during these years. The annual average year-long maximum temperature is 41 °C (105 °F). Summer nights in Dallol get down to 32°C (90F).
Marble Bar, West Australia, has an average of 41°C in January for the last 100 years. It holds a world record for having 160 days above 100F from 31 October 1923 to 7 April 1924. About 200 people live there. (See more Marble Bar photos.)
In Kebili, Tunisia, the average July max is 41.7°C and sixty thousand people still live there, so I think it gets the medal for “hottest inhabited town”. Curiously in this warming world, Wikimedia notes that the hottest temperatures (all 50°+C) were recorded from 1888 – 1930, and not since. Presumably those old thermometers needed adjustment.

Humans, apparently, have lived in area’s around Kebili for at least 2,000 years, and maybe, possibly, 200,000 years. (I expect they are probably used to it by now.)

The coldest inhabited places

Coldest Inhabited Place on Earth, Oymyakon

Oymykon, Russia

Five hundred people live in Oymyakon, Siberia, Russia, almost in the Arctic circle at 63N.  The average temperature for January is -50°C. The village is called the coldest permanently inhabited settlement in the world, and there doesn’t seem to be anyone arguing about it. (Though technically, the research station at Vostok, Antarctica has a monthly average of – 68°C, and about a dozen people manage to live there.)  In winter in Oymakon, there are only three hours of sun a day, and people have to heat their garages, or run their cars 24/7 to keep them usable.

The coldest ever temperature recorded in Oymyakon was -71.2°C. Read more at Dailymail, and Wired.

PS: Great minds think alike:  I did the first draft of this January 17th, but spookily ROM in comments had the exact same thought 2015/06/05 and 2015/04/17.

PPS: There must be someone out there with a really good shot of Marble Bar heat. Please send in that better photo…
