We certainly can, from the technical standpoint, do some terraforming of Mars. No question of that. Whether we have the economic ability and political will to see it through is in doubt. Can you imagine terraforming being done on an annual budget basis with Congress apparently unable to dependably sustain the continuity of any program that lasts longer than a couple of years? Not to mention working with Europe, China, Russia, Japan, India, and whoever on any rational project at all.
Oh, I get what you're saying now. I totally misconstrued your above remarks. Sorry!
Heh.. We are in complete agreement. The simpering Euros are falling apart as we speak over trivialities, and I don't even want to get into our ridiculous congress critters..
Speaking of Mars, did you notice the other day, they reported that the Martian polar ice caps are receding the last few years...
Don't know if this suggests anything that might contribute to Earth's own temperature variations...
