I disagree with your last sentence. The only reason climate change reaches this point is because humanity doesn't fear climate change enough because we couldn't comprehend the impact, until recently of course. I'm pretty sure scientists had warned us since the 19s when humanity started to capitalize fuel but no action was taken. What else can they do except to spread fear? And scientists already provide solutions for climate change long ago, but people can only see short term profit, and ignore the damage that can be caused by the profit in the long term, since humans don't live long enough to care for the long term except for the younger generation which will face the consequences i guess.
