For GSS Life and Climate chapter 13. Excerpt: Here’s what your future will look like if we are to have a shot at preventing devastating climate change. Within about 15 years every new car sold in the United States will be electric. In fact, by midcentury more than half of the American economy will run on electricity. Up to 60 percent of power might come from nuclear sources. And coal’s footprint will shrink drastically, perhaps even disappear from the power supply. It offers a sobering conclusion. We might be able to pull it off. But it will take an overhaul of the way we use energy, and a huge investment in the development and deployment of new energy technologies. Significantly, it calls for an entirely different approach to international diplomacy on the issue of how to combat climate change. “This will require a heroic cooperative effort,” ...The teams, one in each of the 15 countries, looked at what would be necessary to keep the atmosphere from warming more than 2 degrees Celsius, 3.6 degrees Fahrenheit, above the preindustrial average of the late 19th century, a target that most of the world committed to at the climate summit meeting in Copenhagen five years ago. To do so, CO2 emissions from industry and energy use would have to fall to at most 1.6 tons a year for every person on the planet by midcentury... The decarbonization paths rely on aggressive assumptions about our ability to deploy new technologies on a commercial scale economically. For instance, carbon capture and storage is supposed to be available starting in about 10 years. Second-generation biofuels are assumed to come into play by 2020. Hydrogen fuel cells and power storage technology are deployed starting around 2030. ...Big challenges remain. Any 40-year forecast must be taken with some skepticism. Technologies that seem feasible and economic today might turn out not to be. And it bears repeating that though the teams contend they can get to 1.6 tons per person, they have not yet. http://www.nytimes.com/2014/07/09/business/blueprints-for-taming-the-climate-crisis.html?ref=science&_r=0.
