Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

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.
