IT isn't the heat that will damage the human race the most. It is the wind.

As a precognitive psychic and profiler because of my extremely logical mind from being a computer programmer I often am aware of things that others are not. This is one of many reasons I'm still alive at 75 years of age because I am extremely adaptable unlike many people. I also come from Pioneer stock in which good instincts and intuition were a matter of life and death ever since my forebears on my Dad's side came here to Philadelphia from Switzerland around 1725.

So, what I can see clearly is that the winds are what damages human survival the most ongoing all over the earth. Hurricanes will get worse and worse and places like the Caribbean and the South East of the U.S. will more and more become uninhabitable simply because of winds over 200 to 300 miles per hour periodically from Hurricanes. However,  I suppose if people built underground shelters that they moved into (as long as they weren't being flooded out by the storms accompanying the winds might survive all this. If you have ever been to tropical places like Hawaii, Florida or the Caribbean you do know that foliage even if blown completely away (every single leaf on everything) will soon come back within a few months but trees take much longer to recover usually unless they are completely blown down then they are over permanently.

So, being mobile like with a motor home or camper or a good tent that you can leave in your car for escaping winds and storms is going to become more and more necessary in tropical areas over time to run away from storms. Because you either need to hide from storms or you need to run away from them one of the two to survive them more and more over time.

So, whether in Hurricanes or Tornadoes or just wind storms carrying rain or snow or nothing but dry winds are what prevent people from farming when the winds are over 100 mph because no leaves on ANYTHING living will be left behind and most plants will die unless they are in a protected Greenhouse or Shelter of some kind.

So, well built greenhouses will be absolutely necessary to keep leaves on things during these times which could hit literally any time of year around the world depending upon it.

Once again winds will increase exponentially as the oceans heat up and as the ice caps melt and as the seas rise more each year now. Many cities on the coast of oceans will be slowly eroded away now sort of like Venice to the point where first floors of many building will be underwater. this is why building out of cement reinforced internally with rebar and metals will be necessary because eventually wood rots when it is in the ocean even if it is treated with various things to preserve it. I suppose you could use plastic wood but i haven't seen this in pier pylons for example, probably because casting plastic wood this big isn't possible yet. It likely would be cost prohibitive.
