Survival of the fittest on the 'Red" Planet

It's a cloudless day but the sky is dark with smoke

There have been about 500 forest fires so far this summer in Northern Ontario and a similar number are burning in British Columbia. That's about twice as many as normal. Today's temperature in much of Northwestern Ontario was 32 C or 90 F. The atmosphere is so full of smoke you can look directly at the sun. It just looks red. In June, 50 people died from the heat in Quebec which just happens to be the only province that keeps a close watch on that statistic. People are dying from the heat in Canada! What does that tell us about the state of the world?
It makes me wonder what is going to survive as we turn the planet into a barbecue. The cold climate species are toast, that's for sure.
Insects are supposed to be the big winners, especially mosquitoes.
When it comes to mammals, I would bet the whitetail deer will find a way to survive. Right now they have found a way to adapt to just about every climate. I have seen them on some of Canada's tallest mountains, in the arid Prairies and of course, here in the Boreal Forest.
A maxim that humans get wrong every day is "survival of the fittest." People immediately interpret that to mean "survival of the strongest" and that is definitely not the case. Whitetails are tough animals, that's for sure, but they certainly aren't stronger than moose which are disappearing, seemingly from the heat.
