“Global warming may or may not make life shitty in some future scenario.”

I think you’re trying to rationalize the position of the protesters, but this is a dangerous rationalization.

Arguing that it “may or may not” lead to catastrophic consequences leaves the door open for doubt.

I understand if poor people or nations are frustrated, and I agree that the rich have a responsibility to show leadership, but there should be no doubt that climate change will most negatively affect the poor.
