What do you mean by massive disaster ahead? Are you stating there is a massive disaster ahead, or COVID has steered us into a direction that adverts that?

Think he/she is referring to climate change. COVID is a good way to gain a mental understanding of what to expect when climate change finally hits as it will be much worse. I do think the odds of "billions" of dead is one of the less likely outcomes but maybe millions yes.

How do you exactly compare extremely slow, glacial environmental changes on geological timescales to a pathogen that engulfed the entire world in weeks?

What can anyone gain from such a comparison except baseless soundbites intended for fear mongering?

The difference between natural and human-triggered climate change is that it is much faster than geological timescales. And it keeps accelerating.

We're talking decades not weeks but it's still relevant to our lifetimes and the next generations

Climate catastrophe?

clathrate gun hypothesis is now mainstream?

I'm not sure everyone only talks about climate change as if it's about as rapid as an asteroid impact.

Yes, climate is an issue, but unnecessary hyperbole only seeds more distrust, just as denying that masks help in the beginning damaged credibilty of COVID-19 related information later on.

>Sure those who are mentally not agile enough to travel to this different world currently born, well they will stay behind and swept away with the refugee crisis yet to come.

Who do you think consist of these groups?
