How Climate Has Shifted Over Millions of Years I NOVA I PBS
When it comes to our planet’s fluctuating temperatures over the last 34 million years, a lake in the Russian Arctic has lots to show.

Climate change is the bastard son of global warming that was proven wrong! The only other bigger lie is evolution! You need to stop this and seek the Lord!

Yeah, we don't understand anything about it, but we blame humans anyway.

Unregulated geoengineering of emission of a basic component of climate regulation, CO2, fucks things up. Pretty simple.

If we do put the planet to a point off no return we are finished as humans. It's if it's when. I think the oceans will be first due to ph levels rising to quick from co2. Life will go on and recover, we just won't be here to see what happens. I guess a good question would be how long do we have before it's to late?

A doc on how the milankovitch cycles combined with the extra co2 we are adding to our oceans plus other stressors like population and deforestation will effect us in the near future would be interesting. Could we tip things to far? Also will be interesting to see the results off less co2 during 2020 due to coronavirus.

In other words we really dont have a solid understanding about how the Earth climate system works but we know enough to guess and yet we somehow know for fact that global warming today is a catastrophic crisis!
