Earth warms up and cools down naturally that’s a known fact. But over thousands of years, not 200. What we’re witnessing right now is not natural and we have the data to support it.
Millions even, we haven’t been this warm in millions of years! And same for our co2 concentrations. All done in the blink of an eye geologically speaking. We’ve reversed a natural Co2 trend in only 0.004% of the time!
The commenter above you and anyone in doubt desperately needs to see these graphs:
If we follow projections and do nothing to change our behavior we’ll get to levels and temperatures not seen in hundreds of millions of years, all bascially instantly when compared to the the ability of life to evolve and adapt. Earth will survive, it’s been through worse. Gonna be rough on the humans though. We were 10c temperature above where we were then, but it would be even worse now of we got back to those co2 levels, becaue of differences in orbit and solar activity.
Furthermore: we shouldn’t care too much about the speed at which Earth heats or cools down on its own. If we know we’re a significant factor alongside its natural processes, we should still contribute to the NET temperature being one that’s appropriate for human life. If the Earth was heating up this fast naturally, we should still try to cool it down by artificial means, if possible.
