...even if students themselves aren’t spurred to activism by REP, the statistics speak for themselves. Since the program was started, College-wide energy consumption has decreased by 9 percent, $288,488.56 has been saved in lower energy bills, and 885.24 metric tons of CO2 has not been added to the atmosphere. With the exception of Winthrop, all of the houses have shown a reduction in their energy usage, with Mather leading the way with a 12.4 percent reduction over the past three years...
Many climate shocks have already become more common: powerful hurricanes, droughts, heat waves and blizzards. Much worse will come unless we stabilize the level of carbon dioxide, or CO2, in the atmosphere at safe levels. Before the industrial era, CO2 concentration was 280 parts per million (p.p.m.) in the atmosphere. If current trends continue, that could reach 560 p.p.m. by mid-century. Yet because our energy system is so deeply embedded in the world economy--in vehicles, power plants, factories, residences and office buildings--it will take decades to reamp it. So people who care about the future...
Concerned citizens will also have to think globally. The U.S. is about to be overtaken by China as the world's largest emitter of CO2 from energy use. For years we have brushed off the rest of the world as other countries have pleaded for the U.S. to get its house in order. Now as China's CO2 output threatens more intense hurricanes and droughts in the U.S., the tables are turned, and we will certainly want China to control emissions. In fact, since CO2 mixes freely in the atmosphere, every country's climate depends on the whole world...
...deal has implications far beyond Texas. The Lone Star State is No. 7 in the world for greenhouse gases (emitting more CO2 than Britain), and TXU is the state's biggest corporate contributor. Those 11 coal-fired plants would have thrown off 78 tons of carbon dioxide a year--double the savings expected from California's Clean Cars legislation, passed last year. The buyout firms promised not only to halt eight of the Texas plants but also to terminate plans for coal-fired operations in New Jersey, Virginia and Maryland--a recognition that momentum is growing in Washington for legislation...
...global warming is heating up. European Union officials have agreed to cut CO2 emissions 20% by 2020 and say they are ready to go to 30% if other industrial nations join...
