You've been studying ice cores in the tropical region's glaciers.
That's right.
Is that right?
You got it.
What is an ice core?
Look, Lonnie, I know.
They don't know.
What's an ice core?
An ice core is a cylinder of ice.
They're about four inches in diameter.
Yep.
And we drill them.
We use a drill just like you would drilling for oil.
You go down, you bring up a core, and you can drill 100 and 200 feet, or you can drill three miles in Antarctica where we have lots of ice.
So what does that cylinder tell you?
Ice is amazing.
I can say that.
I've spent my life studying this stuff.
Ice tells us not just climate, things like temperature from the isotopes in the ice and precipitation by the annual layer thickness.
Meaning in those years.
