Can't say anything about weather, but climate change is real. There is no prediction needed. I'm not a militant, but we are going to see huge self inflicted damage in the very near future.
Vak is right that fossil fuels need to go away and it is impractical to do so right now. It takes a long time to change something so deeply entrenched. We are going to be poorly prepared for this change because our society is very conservative, openly hostile to change and is corrupted by a powerful, unimaginably wealthy industry.
