Doom is not imminent. We will see 1-2 C global warming and species die off. Also flooding in low lying areas. Also movement of disease-vectors into areas previously too cold for them. This isn't even a prediction, it's already happening. But it's not doom, it is a degradation of the world we live in although the hundreds of thousands or maybe millions of people directly affected might say otherwise. The rate at which fossil fuels are being dumped into the atmosphere will take this degradation to higher levels and it's not too late to stop it.
Right now, we deal with a government administration that denies science. Until they are dealt with, we can't make progress on this issue. So, that's the objective for now.
