It's like you're on a boat that sprung a leak and everyone grabs a bucket. But a few people choose to not help because it's not fair for whatever reason.
I'm not an expert, but from what I have read I believe humans do have an effect on climate. However this doesn't mean that any draconian measure that would essentially impose one world government and population control (which is the inevitable outcome of all of this) is preferable. But more importantly I'm anti stupid measures like restricting air-conditioning because they make a negligible impact and literally kill 100k+ people a year.
