Cars Driving Climate Change

smog NASA researchers confirm that automobiles are the planet’s #1 source of emissions of substances suspected of causing anthropogenic global warming:

In a paper published online on Feb. 3 by the Proceedings of the National Academy of Sciences, Unger and colleagues described how they used a climate model to estimate the impact of 13 sectors of the economy from 2000 to 2100. They based their calculations on real-world inventories of emissions collected by scientists around the world, and they assumed that those emissions would stay relatively constant in the future.

In their 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.

The NASA scientists say, correctly, that conventional reports on climate change focus on chemicals, rather than the sources of the chemicals in actual economic sectors. Only by focusing on the latter, they argue, can we “identify effective opportunities for rapid mitigation of anthropogenic radiative forcing.”

So, if cars are the #1 source of anthropogenic global warming, what do you imagine might be the #1 policy requirement for rapid mitigation of the problem? Rather obvious, but utterly unmentionable…
