I've shared this before (probably in this thread), years ago some respected Chicago economists reviewed  the global warming situation from a cost benefit analysis.  Indeed we could actively cool/warm the planet by altering the albedo. Past massive volcanic events have demonstrated the ability to alter global temperatures with particulate emissions into upper atmosphere.

Of course we must be cautious about altering input terms to a chaotic system. The only good thing to be said about the current political strategy regarding fossil fuels and carbon dioxide, is that it won't change anything enough to destabilize the climate, while it can have a significant impact on wealth and world poverty. Higher energy prices disproportionately harm the poor.

I read today that the current evidence is that the earth experiences a big meteor strike on average every 27 million years and that most cause extinction events. And since the last one was over 60 million years ago we are about 30 million years overdue. With those odds it might well occur before global warming wipes us out.

Cheers
