I think the horrendous weather in Texas is a pretty convincing sign. As usual, it will take us going to the brink with it before we face up to the brutal reality. People can be very arrogant and not want to be seen to change their stance on something...even when it's pretty obvious. 
Yes i heard that there is a big hurricane problem in the south USA. And this is only going to get worse. Wait until India , Bangladesh or Netherland gets under water due to the sea rising. If you think the current immigrant problem in Europe is bad, wait until 1 billion people will start migrating all over the place.
