Well, I’d say, from my perspective, its a given that technology WILL in fact save the day. Its either that or the world is doomed…and I have my doubts the world is doomed. No idea if anyone could do what you are asking (my guess is…biotech isn’t quite there yet, maybe not ever), but certainly OTHER technologies seem poised to take a big bite out of the global climate change picture (if in fact humans are the major cause).
Hydrogen powered vehicles are only a few years away (Toyota plans on releasing a full production version in 2015 and GM in 2010 IIRC), and most of the car companies are talking about hybrids now…especially the Japanese who are poises to provide a boat load of hybrids in all makes and models. And these are the next generation hybrids…much better than even whats currently out.
With gas finally going over $60/barrel I’d say that some alternatives will now be able to compete. On the power generation side (which you’ll need for one thing to make all that hydrogen fuel), new nuclear reactors are coming online in other countries that are smaller and a lot more efficient. If the US can ever break the grip of the old style enviro-nazi groups and they ridiculous aversion to anything nuclear, I think this will go a LONG way to solving ‘global warming’.
I’m sure the gloom and doomers will be along shortly to say that we are all doomed unless we go back to living in caves (just kidding btw :))…but I think ‘The Market™’ will provide, because folks will want to buy. And if folks want to buy…someone out there will figure out a way to sell it to them (for a profit). If gas prices stay high (and I see no reason they will ever drop back down again), then sometime in the very near future someone is going to figure out a way to make a better mouse trap…and make a fortune off it.
