Rebooting the Ecosystem

What's more, many greens worry that just talking about geoengineering could deflect funding and focus from the task of cutting greenhouse gas emissions. They'd rather we legislate higher fuel-efficiency standards and design better photovoltaics. Enviros are right about the urgency of kicking the fossil fuel habit -- that's a no-brainer. The problem is inertia; the changes we have wrought in the atmosphere will play out over decades (or longer) whether we junk all the SUVs tomorrow or not.

That's why it makes sense to start thinking seriously about radical countermeasures.


Strangely, we may have hands-on experience with terraforming long before we get around to it on Mars.
