I think you are saying that climate change can be dealt with. That may actually be true. However, its not gonna happen. The first problem is politics and the second are national boundaries, worldwide. Between the two what we are going to get are floods of refugees (already started on our southern border), and entire nations getting desertified whilst actually invading neighbors. There are records of ice age changes and its gonna happen again.
There are, we are told, actually solutions to mitigate. That too isn't going to help. Eventually the more adventurous are going to try and fix it by 'helping' the atmosphere with chemicals, etc. One mistake and EVERYBODY dies!
Sorry - not a big believer in humanity's ability to actually act in its own best interest.
