Tonight on the National Geographic Channel at 10pm EST/PST Earth the Biography: Oceans. An episode on Atmospheres is before it at 9pm. "Explore how half of Earth's water originated from the planet's inception and how the other half was deposited by comets."
Thanks for the heads up!
I long for the days when these things were on PBS so everyone could benefit from them :{
Philip, I feel for you. I don't have TV service so I didn't get to see it either :(
That said, is anyone willing to comment on it in this thread or in a guest post?
