Some of the places on earth people might survive better this century are Canada, Alaska and Siberia. Why?

 Because of global climate changes.

As the world heats up the most extreme changes likely will be around the equator or at the poles. So, finding a "Sweet spot" that doesn't get too cold or too hot year around to grow food or flood out or drought out is going to be everyone's quest who survives on earth this century.

To simply stay somewhere because you like to be there will be ONLY a choice the rich make and survive it.

This is what this century looks like now.

It's true that the wealthiest can survive almost anywhere on earth and be okay simply because they can drive a car or truck or fly a plane or take a yacht to anywhere they need to be within minutes or hours of a hurricane or a drought or a flood. 

But, most people simply are not going to survive what is going to happen this century when it hits because they just don't have enough wealth to survive what is coming worldwide.

Only the richest and most survival oriented among mankind are going to survive what is coming for us all this century.

Just remember the average temperature at the north pole about 1 million years ago was 76 degrees Fahrenheit at the North Pole. We might be heading back to this slowly or quickly once again.

When you have an average temperature like this usually you have a range mostly of between 60 and 90 degrees Fahrenheit in a range like this year around.

It took almost 1 million years of ferns then to suck up enough CO2 around the world to make it like it was during the 20th century. Ancient prehistoric ferns are one of the best plants to suck up CO2 around that there are on planet earth.
