So, we've got a goal - 450 parts per million by 2050. How are we gonna do it?
Here's the facts:
Slowing ourselves down that much - especially with the massive increase in emissions that developing nations have chipped in, and the massive consumption of the US of A - is gonna take a lot of work. And not only a lot of work, but a lot of hard choices.
On the one hand, we have 41 years to make some progress. But on the other hand, that seems like such a long time. I mean, do we really have to start right now?
Short answer: Yes.
Slightly-longer answer: My god, people, yes!
The longer we hang out, business as usual, habits unchanged, the closer we get to feedback loops - the short story there is bad, but I'll save it for another time.
Because right now, we're talkin' about Stabilization Wedges.
It's a stupid term; here's how it breaks down.
Each stabilization wedge is a plan of action to reduce carbon dioxide emissions by a (relatively) small slice, with the goal of stabilizing the level of carbon in the atmosphere by 2050. Hence, stabilization wedges.
There are a lot of wedges. One for each way we can be a little better to the Earth's natural order of things. They range from replanting forests to cutting average distance driven in half to building nuclear plants. There are a ton of options, and we'll be exploring them with you, one by one. Here's the key, though - we don't have to do every single one. We just have to do enough of them to reach 450 by 2050.
It'll be a lot of work - but we've got the plans. We're already working on plenty of 'em - take the hybrid car wedge, for example. We aren't there yet, of course, but we're making progress.
