...potentially positive effects of climate change, at least in the short term, is that increased concentrations of carbon dioxide in the atmosphere may enhance the growth of plants. That could be good for agriculture - though warming temperatures and changing rain patterns in a warmer world might wipe out that advantage. But there are no unalloyed gifts from climate change. Recent research suggests that global warming will also exacerbate respiratory allergies, as higher CO2 concentrations lead to vast increases in ragweed pollen production. "There's no denying there's a change," says Paul Ratner, an immunologist with the American College...
...goes for energy use, or travel. It's great for magazines to come up with 51 ways you can save the environment, but relying on individuals to voluntarily change their behavior is nowhere near as effective as political change aimed at speeding the transition to an economy far less carbon-intensive than our current one. So, by all means cut back on the burgers - I recommend a nice deep-fried scorpion - but remember that your choices from the takeout menu will matter less than the choices made by those who inherit the White House next January...
...turbines rather than as a significant source of electricity, according to Gray. The turbines will also be valuable due to their visibility and the statement they make, Gray said. “[The turbines will be] an outward statement about looking and examining renewables on campus and lowering our carbon footprint,” Gray said, “like walking by a beautiful bouquet of flowers.” Small-scale wind turbines, which are installed on approximately 3,000 American homes, are generally not economically feasible, according to a recent report by the American Wind and Energy Association...
...billion in damages. Now imagine those storms potentially amplified by the unpredictable effect of global warming. We need to be prepared. Gustav caused far less damage than Katrina because it was a weaker storm, yes, but also because we were ready this time. But we also need to reduce carbon emissions and blunt climate change - or we may experience storms for which there is no preparation. (See photos of Hurricane Gustav here...
...prospective wind turbine installations are part of a larger campus focus on sustainability and carbon emissions. In an announcement made earlier this summer by Faust, committed Harvard to reducing its greenhouse gas emissions 30 percent below 2006 levels...
