First, right now, so CO2 levels right now are about 418, 420 parts per million.
which is higher than it's been in 10 years, 20 years, 50 years.
And as a geologist, here's why I can say that.
When we go look at the geologic record, there are times we've had CO2 levels have been 1,000 parts per million, 2,000 parts per million.
It was definitely a little warmer.
The sea levels did rise, okay?
That's a problem for people that build...
10 feet from the sea thinking that the sea is always going to be 10 feet away.
Some of the most abundant times for life during Jurassic period, Cretaceous, during these periods.
And what's interesting is you can have very high carbon dioxide levels historically and the temperatures are low.
And vice versa, you can have high temperatures and the CO2 is low.
And then one of the kickers is from the Vostok ice cores.
