Always fascinated by what science can teach us about the floating marble we live on.

thank you. love this stuff!

actually this is sort of scary. when glacial antarctica does melt entirely, we're in for some serious climate issues. this planet has NEVER been stable. in fact. billions of years ago, our atmosphere was methane based. change just IS and always will be a factor on our giant, slushy ball of fire, water, air and earth

I can't access that link

But I love all the science shows out there.

^ the link requires me to link to a local PBS TV station in st. paul ("confirm your station"), maybe there isn't one compatible in your area?
