Automatic TRANSCRIPT

I'd like to introduce our special guests for today. He's professor David Archer, professor a geophysical sciences at the university of Chicago anythi, author of a rather disturbing. New book is called the long far how humans are changing the next one hundred thousand years of earth's climate. He argues in the long Faulk that not only are humans ruining the atmosphere of the earth by dumping copious quantities of carbon dioxide, but the effects of this will linger in the atmosphere, not just for years, not just for centuries, but one hundred thousand years, and what does it mean? What does it mean for us to live in a world with that much carbon dioxide and that much global warming? Once again, the special guest is Dr David Archer of the university of Chicago. The book is called the long thought. Professor Archer as a youth. How did you first get interested in science and in particular earth science, I guess they look to the cursed. The functioning of the earth is stable geochemical cycles of things like that. That's bigger than than people. Are I look to the natural world sort of reverence? I think that's what brought me into the natural sciences. Why I chose to study the oceans actually instead of force or other planets or stars or something like that. Because I've always had a romantic love of boats but nine ended up living in Chicago anyway. But that's just one of the jokes. I guess. Okay. Well, let's get right into it. First of all, what is the relationship between carbon dioxide and global warming. Carbon dioxide traps infrared light that tries to leave the atmosphere. It's like if you put a coat on in the wintertime it did traps the heat leaving your body. So it allows your body to to to warm up theory about CO two how it affects the climate of the earth, and how much it affects the climate of the earth is over one hundred years old now, it's very very solid science. But there were no greenhouse effect. We wouldn't be able to explain why the earth isn't in a d pres or the climate of Venus or or lots of other things at the very solid, and we'll talk about Venus, some people call Venus, the greenhouse planet..
