It is completely possible to acknowledge that we are in a warming portion of the climate cycle without being hysterical and advocating draconian responses.
We actually shouldn't even refer to *global* warming, as it has been reported that no discernable warming has been perceived in the Southern Hemisphere over the past 25 years. My Kiwi correspondents have complained for months about their cold, wet summer. That is anecdote, not data,of course, but then, so is a lot of the information being disseminated in support of anthropogenic warming.
I just don't agree that the changes are severe enough to warrant the sorts of huge space-based responses that will take so long to implement that by the time they are in place will be obviated by yet another swing in the opposite direction.
Hysteria is never helpful but sometimes it's entirely reasonable to non-hysterically call for draconian responses. For example, I am in favor of draconian (by which I mean very severe) punishment for companies that knowingly employ illegal aliens.
So, do you consider the idea of investigating the deployment of a space based shield and/or other active interventions sometime in the next hundred or so years should it be feasible and cost effective a draconian response? I don't. I'd even be tempted to call that characterization hysterical.
