'Dino farts'? Apparently earth's CO2 levels are as high as they were 800,000 years ago and inquiring minds want to know who was responsible back then

Breaking human-caused climate change news:

Carbon dioxide levels in Earth's atmosphere rose to levels the planet hasn't seen in 800,000 years in 2018, underscoring the impact of increasing environmental damage due to human activity, according to a new federal report. https://t.co/N21sLYmC9H

Wow. The highest in 800,000 years!

Just like 800,000 years ago. You know, the last time humans caused this.

What humans raised levels this high 800k years ago? Curious

So did humans cause the rise in carbon dioxide 800,000 years ago? I’ll wait for the answer.

So how many humans were burning fossil fuels 800,000 years ago again?

So, let me get this straight.

We've been here before, as far as CO2 levels are concerned, but THIS time it's my Honda's fault?

That was why they paused the manufacturing of the Cadillac El Dorado in 798,000 BC…

I used to drive an 800,000 BC Buick Regal https://t.co/PETxqayiwb

So, if it is “irreversible” now, why wasn’t it “irreversible” then?
Why didn’t the runaway greenhouse ensue?

But we've only got 12 years left. Not as lucky as those damn polluters from 800k years ago, I guess.

So what you're saying is, the earth on its own reached this level of CO2 before and made it out just fine.

OR… Here me out now- It underscores the cyclical nature of our climate.

But you know people bad n stuff.

How much comes from Russia, China, India and so forth?
