Why will increasing heat on earth make lt more difficult to physically survive?

Heat causes two things:

1. It causes stronger and stronger winds
2. It causes extreme evaporation off the oceans, lakes and river and the ground itself all over earth.

Then, where does this heat and moisture go?

It goes different places usually than normally before.

Why?

The increased heat in causing more extreme winds causes new weather patterns worldwide mostly not seen before.

Why will their be more flooding some places?

Because increased evaporation results in more rain clouds off of oceans especially. Then combined with the heat of the water of the oceans and the heat of the air, evaporation increases exponentially. As winds and heat increase all the ice begins to melt on earth. Ice is white but oceans tend to be blue. When Ice melts the blue oceans absorb much more heat than Ice does so this increases exponentially the melting of more ice in the ocean.

However, ice in the ocean displaces about the same amount of water whether it is ice or water.

But, over land when the ice melts like on Antarctica and Greenland it is not displacing ocean water until it reaches the ocean. Therefore, water in all the oceans is expected now to raise by 5 feet worldwide by 2100. This will put underwater places like Bangladesh for the most part, a lot of Florida and other low lying places like Venice, Italy and parts of most coastal cities on earth. This will cause during storms people moving inland to survive these storms in coastal cities around the globe more every year during hurricanes and Cyclones and other weather events.

As the incresed heat results in more and more winds above 100 mph worldwide and more precipitation it also raises the possibility of Ice ages.

How would this possibly occur?

PHDs in Climate Science know how this happens. It happens at first sort of like a fluke.

For example, imagine much more evaporation off the Pacific ocean than now coming off the ocean onto land into California, Oregon and Washington. Imagine a cold Polar Vortex dropping from the arctic one winter timed perfectly into Nevada, Eastern WAshington and into Utah, Colorado and most of the eastern United States East of the Mississippi River. If we had say 5 to 10 inches of rain during this Cold Polar Vortex it is theoretically possible to get 5 to 10 feet of snow from the Sierras and from the Cascades east all the way to the Appalachian mountains. So, it would begin in the Sierras and Cascades and go all the way to the Appalachians. Then imagine the snow starts to melt off and then another polar vortex hits the same areas and drops another 5 to 10 feet of snow (which is only 5 to 10 inches of rain). So, we see theoretically how extreme heat could create an ice age with a little help from a cold polar vortex.

Then, if you know anything about mountains with snow they tend to create their own weather. In other words when snow falls in mountain ranges it tends to snow more there just because of the refrigeration effect of the first snows that fell often. Only now you have 5 to 10 feet then 3 to 4 feet melt off then another 5 to 10 feet come down in the second Polar cold vortex from the north pole regions.

Then because of all the evaporation it is so cloudy the snow never really melts off that summer and more snow falls the next year and the next and the next and so on.

This is how an ice age from the Sierras to the Appalachians could theoretically begin and Phds in Climate science actually predict this given the right conditions.

Will it actually happen?

I don't know. I just know that with increased evaporation never ending now and increased heat in the atmosphere in combination that forces are unleashed in more and more extreme ways that we have never seen before on earth. So, we don't really know anymore what might happen from now on worldwide. To not see how unpredictable everything now is is to be pretty ignorant of what is actually coming.
