The worst problem mankind faces is not Flooding or droughts or fires or earthquakes:

 The worst problem we face this century is the ever increasing winds which will affect everyone everywhere to a greater or lesser degree.

Who will be affected the most by these winds?

People who live on flat plains or where the oceans meet the lands and prevailing winds are coming off the ocean or off the deserts onto the ocean like California. But, mostly it's the Great Plains in the U.S. that will be the worst place to be with 300 mph or greater winds inside of Tornadoes tearing down everything in their path.

It's basically the same all over the world where the winds are going to get stronger and stronger.

Why will they get stronger and stronger?

Because as the seas get hotter they are like Heat Batteries. Heat Batteries make the winds stronger and stronger around the world because most of the world is oceans not land.

So, as the ice melts in the north pole and south pole regions and Antarctica (which is a land mass under the ice) melts off many people might start moving to Antarctica more in the future just because it might be cooler there.

Then you have 60% or more more rain possible every 10 degrees you go higher. So, summer monsoon rains around the world will flood more and more around the world.

Then as the winds increase across the oceans ships will flounder more and more to where ships might have to become more like submarines that can go deeper where the winds shouldn't affect them as much.

Also, jet passenger planes will be more and more affected by the winds too to where it will be advantageous to go straight up out of the atmosphere more and more and then come straight down like on a parachute or something to avoid some of the more serious wind shear.

And we will develop all sorts of water and air and space technology to deal with all these things too.

So, it's a slow progression to where people will know not to go above ground in these really high winds that will eventually blow down all wooden structures not reinforced by cement and steel. Also, tall buildings will start to blow down more and more around the world too.

You will know when they are going to blow down when all the windows on one side of the building are blown out in the winds and the curtains are blowing outside of the windows. When you see this you realize it is no longer safe to be in that building because it's going to blow down within 10 years of this.

This is all a natural progression of Global Climate changes which should increase exponentially for the next at least 300 years. It's possible that the earth's population of humans might be reduced by as many as 50% by 2050 at the present rate of wind increase and flooding and drought increases.

And what Trump is doing is only increasing the deaths worldwide exponentially of people as well which is why all the best and brightest young scientists who understand this like I do are leaving the U.S. by the millions now to find jobs overseas in a friendlier Science Environment where people might better survive than they presently will in the U.S. under Trump.
