Trump's effect in the future will be:

Causing an incredible amount of deaths in the poor and middle Class worldwide.

As government (all governments on earth) are demolished by Trump and his cabinet ALL protections of the Middle Class and poor not only in the U.S. but also worldwide are being destroyed.

The end result of all this is: babies not conceived, conceived babies not being born alive, people dying that otherwise wouldn't have died if they had health care, people not being allowed in the U.S. that would have been allowed, people dying overseas because of a lack of protection from the U.S. government or the U.N.

So, I would say that by 2080 or 2090 there will be about half the people alive on earth that would have been alive had Clinton been president.

The bad thing about this is the 1/2 of world population dead or never born.

The good thing about this is the human race likely won't go extinct from overpopulation.

At least we won't go extinct between now and 2100.

After that it's anyone's guess.

The other effect of Trump is people will generally have to move towards Canada, Siberia, Antarctica more and more the rest of this century (unless the Maunder Minimum kicks in for about 30 to 40 years and then during the Maunder minimum of the Sun they will have to move more towards the equator for about 30 to 40 years and then they will have to move towards Canada, Siberia and Antarctica once again.

So, if we don't have a temporary ice age for the next 30 to 40 years we likely we will be moving towards Canada, Siberia and Antarctica by the end of this century once again.
