Here’s more evidence that proper public transportation tied to appropriate land-use planning can have have a major impact on climate change.

NASA Goddard reports on new research in an article entitled, “Road Transportation Emerges as Key Driver of Warming.” In the analysis,

motor vehicles emerged as the greatest contributor to atmospheric warming now and in the near term. Cars, buses, and trucks release pollutants and greenhouse gases that promote warming, while emitting few aerosols that counteract it….

We already know how to use this information, so we should get to it. Better cars, whether hydrogen powered or electric, are not a solution. We need to vastly improve growth and planning approaches,  so that public transportation works best. Besides, sprawl, and the accompanying traffic that goes with it, is bad, and we all know it.
