My guest tonight is a paleoclimatologist whose pioneering research collecting ice cores to study climate change is featured in the documentary Canary.
Please welcome Lonnie Thompson.
Thank you for coming, and thank you for all the work you've done.
Thank you for... Man, that doesn't seem easy, what you've been doing your whole professional career.
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.
