Still with the ice sheets melting, the rainforest vanishing, the tundra defrosting and the continued spewing of carbon and methane the timetable is excelerating..
There are no real precedents for what is happening in the geologic record.
There was a period of significant warming in the past but it took thousands of years. The area near the equator where most of the current population live would have been unihabitable.
We tend to focus on the rise in sea levels which is one of the early issues. But worse than that is the release of trapped carbon gases in things like the permafrost.
This is a problem that feeds on itself, it defrosts, released trapped methane, warming the planet causing more defrosting etc.
It may seem like a natural process by it as kicked off by our behavior.
Methane is significantly worse than CO2 as a greenhouse gas.
How soon will This impact us? Well it has already started but it will escalate quicker.
It's already a crisis but not yet a catastrophe.
Not yet.
