You called it a tantrum. Which means you think that someone can overreact to the problem.

If someone can overreact to climate change, that means you think theres something not that serious about the problem.

If you were serious about climate change, you would understand that making a few people mad doesnt matter as much as getting as many people as possible talking about it as possible, because of how pressing and serious of a threat it is.

But you think doing anything that risks making others mad is too far, a tantrum. Which means you dont think its that pressing, because if you did you would be more concerned about stopping it.

So. What is it that you dont actually take seriously?
