"UK Climate Fix Balloon Grounded"

What have been the speculations in futuristic or time travel novels you've read concerning the prospects of climate change technology?

Do you think a man-made climate change would be helpful or lead to possibly disastrous results?

Is this the only way our current climate is likely to be normalized?

I think the only place man will ever be able to actually control climate is inside artificial domed habitats. Climate, as best we understand it today, is a function of many different variables, over most of which we have no chance whatsoever of exerting any control (e.g. solar activity).

I have this random conversation filed away in my brain from a South Korean student who told me that she'd heard her friends say, when the weather was bad, that they wish the Americans would use their weather-changing machines to help them in S. Korea ... And they meant it seriously, as in ... they thought the U.S. government surely had climate-changing machines at their disposal. Apparently, it was the Brits that particular group of friends should have been hoping for to help them?

I started reading Red Mars where they initially speculated that high-powered windmills placed all over Mars would help bring about a warmer climate that was more conducive to human habitation. If that were true, we'd certainly be in trouble here with the number of windmills we have going. Should we turn them all off now?

I think I'd be hesitant to do something big enough to cause the climate change we'd be looking for unless we (the entire earth) were in a true state of absolute desperation.
