The Washington Post editorializes:
The IEA argues there are things that governments can do between now and 2020, at no net economic cost, at least to try to “keep the door open” to 2 degrees Celsius. Retrofitting buildings and constructing better ones could reduce emissions. More-efficient cars would help, too. These sorts of investments would also save consumers money over time. Phasing out the dirtiest coal-burning power plants would cut greenhouse emissions and other pollutants. So, too, would inexpensively reducing emissions of methane — itself a greenhouse gas — during oil and natural gas production. And, of course, countries should stop encouraging fossil fuel use by artificially lowering prices for the stuff, a problem here that’s much worse in other countries.
In the United States at least, those policies seem achievable, even without agreement among politicians on the scale of the climate problem. [Emphasis added]
