As a result of "climate changes" it has been proposed a lot of things that can go bad:
- Flooding will get worse
- Storms will increase
- More areas will turn into dessert
- Polar ice will melt
- The poor people and third world will get hit the worst
I'm sure that we will see a lot more climate changes in the future. Of course that many get scared about this fact. Me too. What if my hometown would no longer be a place where it's possible to live? We actually had such occasions in Sweden's history not too long ago. In the 19th century there were several years with bad harvests and many people emigrated to north America.
My conclusions is: There will be changes in the world due to climate changes, regardless if AGW is true or not, let's make our best to cope with the situation!
