The other day I had a stark realization about tackling climate change: THERE IS NO PLAN!
Having summits where all the countries sign agreements to voluntarily cut greenhouse gas emissions by so much, by 2030 or 2050 or whatever, with no real sense of how they're going to do it, just doesn't cut it.
If we were really serious about climate change, we'd have to drastically change two things: 1. our suburban sprawl, and 2. our consumer lifestyle.
1. Since WWII we have built our cities on a suburban lifestyle, and this is where cars come in. We keep spreading our urban areas out further and further, and our cities are designed around single automobile transportation. Thus huge areas are dedicated to roads and highways and parking lots, etc., and massive amounts of fuel is required to move people about in multi-ton contraptions. Edd, I believe it was you that posted a video in a thread a couple of months ago about how converting to electric vehicles is going to do nothing to change the massive consumption of energy, resources, and land. We're going to have to start designing our cities to have buildings closer together, and to be closer to work, school, and shopping, to cut down on massive energy consumption. The only way switching to electric cars might make some sense is as a stopgap measure, if renewable energy sources are substituted for fossil fuels. If power plants burn conventional fuels, that would be just switching one fossil fuel source for another. But beyond that, there needs to be a plan to switch off individual motor vehicle transportation, whether electric or gasoline-powered, because either source will create greenhouse gases.
2. We need to drastically rethink our consumer culture. It takes massive amounts of energy and resources to keep making and transporting "stuff" to market. We need to figure out ways to free our economy from being wed to the consumption of so much material. And we need to think about lifestyle changes. For instance, why are new houses built twice as big as they were in 1950, and yet at the same time, we only have half as many people living in them? And we have massive new buildings built with half the volume dedicated to unusable atrium space with massive windows and skylights. That's area that needs to be heated and cooled, etc.
