Probably. By the time legislators get on board, it'll be way too late. It's already too late, but it'll be too late to avoid even the most disastrous consequences.
Let's not forget all the paid politicians, shills, current deniers, and every single company that chooses profit over doing what's right (so, all of them). We're all culpable to varying extents. But people in power had a responsibility to the rest of us, and they chose greed and power when given the opportunity.
