It is unlikely that most humans will be able to change fast enough to be able to survive what is now coming weather wise this century

If you are reading "The writing on the Wall" so to speak you can see how most people likely won't survive the extreme weather changes that we are beginning to experience in the U.S. and around the world.

For example, right now most people in Oregon, Washington (and even in Mt. Shasta, California) don't have air conditioners at all. (simply because they didn't need them until now). For example, my friend now he is semi-retired will go in the afternoons either to lakes or streams to stay cool and come back when it is starting to cool down and is getting dark. This is a method of "Mountain People" that is somewhat normal for people used to skiing in the winter and hiking in the summer and swimming in mountain lakes and streams (which usually can be quite cool from snow melt) (the streams might be 36 to 50 degrees for example. And the lakes depending upon the altitude might be 60 degrees to 70 degrees in the summers. So, instead of buying an air conditioner people semi-retired or retired often just go to the lakes and streams and the shade of trees to "cool down".

But, when temperatures rise above 100 degrees consistently every day unless you string up a hammock outside between trees your house won't cool down below 80 to 90 degrees even in the cool of night these days.

So, this can be problematic too for people who are older and maybe not aware that they are getting heat prostration just sitting inside their homes without air conditioners. So, by the time you sense something is wrong it might be too late to even call for help to save your life.

Now just multiply these kinds of problems by 8 billion people on planet earth and you get what I'm talking about.
