That we're talking about. And what you will find, first of all, the temperatures rise. This is called the inconvenient data because it doesn't support the narrative.
Temperatures rise first. There's a lag. And then the CO2 levels will rise. All right. And you can see that very clearly. Now you go back beyond that 420,000. Now let's go back in geologic time.

Well, but here's the thing. You can have high levels of CO2 and the temperatures are low. You can have low levels of CO2 and the temperatures are high. They're not necessarily correlated. Now, is this the most CO2 that the planet has ever had? Absolutely not. Right now, I think we're at 440 parts per million, I think is somewhere.

Steve, would you check and see? I think it's 440 parts per million.

You're spot on.
You're spot on.
You're spot on.
Yeah, okay. So is that higher than it was 10 years, 15, 20? Yes, but here's the thing. You go back into geologic period, the Jurassic, the Cretaceous. Right, right. We had 1,000 parts per million and Earth was green and lush and life was thriving. 2,000 parts per million, Earth was green and lush. High CO2 is not a death sentence for the planet, but here's what it is, low CO2.

If we drop below 180 parts per million, it's a death sentence for this planet. Now, let's do a little experiment. Let's do a thought experiment. I did this in January of 23.

No, as a geologist, I said, okay, let's look at the proposed CO2 limits. Let's look at the proposed CO2 limits right now. If we were to meet all these limits, what would the Earth look like? They are proposing a reduction from 2010. I think they want about a 45% reduction. It brings us down to about 220 parts per million. All right, 180, 182 is considered a death sentence for our planet.
