Yes, so climate change is going to cause migration. Let me tell you what else climate chane is oin to cause. I haven't covered that here either.
1. Fascism. When people get desperate and when governments don't stop the flooding, the fires, the food shortages, etc. people will believe the promises of a strongman. They will vote him in. That's how fascism has arrived in every single county.
2. The breakdown of law and order. People will begin to rob, to murder, etc. for food. As more and more cities are wiped out through massive rain fall and ice melt, hundreds of thousands and millions will begin to migrate. Riht now, one third of Pakistand is under water. It will take 3 to 6 months for it to go down. Entire towns are under water. The area that is under water is where all the crops are grown in Pakistan. People are stranded in the area that is underwater. They have no food. There are 30 million people that are affected. Of course, there are goin to be migrants. What is your point?
