Anyone happen to see the "Nova" episode on Global Dimming? Something else to worry about.

Its coming at a good time since we have global warming? /forums/images/graemlins/confused.gif

We won't care about that once the pole shift starts though. /forums/images/graemlins/shocked.gif

The way I understood it was that the greenhouse gases trap the heat and the particulate pollution blocks the sun. There are more greenhouse gases than particulates hence the warming. If it wasn't for the particulates the warming would be much more pronounced.

Global Dimming?

I guess I'm in the dark on this one. /forums/images/graemlins/grin.gif

I caught some of it while eating lunch yesterday. I was rather intrigued by some of their findings. I'm no tree hugger, but this is the last and only Earth we'll get so we better start taking care of it.

They certainly laid out a compelling case for the dimming theory. The pan evoporation data going back for a hundred years or so was a surprise to me. I had no idea they have been doing that for meteorlogical data.

Driving home from work today, listening to NPR, they had a real short segment on somone (perhaps a future interview??) who was proposing creating/building in outer space, sort of "curtains" to sheild the earth from the sun.

Seems his idea that he admitted, could cost millions, billions or trillions (no idea but I know it's more than I got /forums/images/graemlins/grin.gif) and take some kind of material, hoist it wayyyyyyyy out in space and literally, build a wall between the sun and us.

That is just about all I heard about it. No idea if his intent is to block the entire earth, poles, oceans or mean spirited continents.

Strikes me as something that would be as costly as it is ambitious. Probably has about the same chances as that proverbial snowball in a hot place.
