lululemon location you might raise your eyebrows. If you get ten in a row

eek or so,[url=http://www.lululemononsales.com]lululemon location[/url], compared with the 100-plus we’ve been sweating profusely under .For those of us who write about climate, extreme weather events—not only heat waves, but also floods, droughts, hurricanes, wildfires and more—are a good excuse to remind readers that while no single extreme event can be cited as proof of climate change, the more you see, the more you have to believe something is going on. It’s kind of like throwing dice: if you get snake-eyes three times in a row, you might raise your eyebrows. If you get ten in a row, it’s pretty unlikely, but not impossible. If you get fifty, you’re playing with loaded dice.Most climate experts are convinced Earth’s dice have been loaded with emissions of carbon dioxide and other greenhouse gases. To help visualize the changes we’re likely to see, my Climate Central colleague Claudia Tebaldi did the calculations underlying the graphic above, which projects the change in numbers of days above 95 by mid-century. The projection is based on a mid-range emissions scenario and uses an ensemble of climate models.Claudia also supplied the data for this August projection, which is slightly different, but carries the same message. There s also an animated version and a more general discussion of summer heat waves here.We re all feeling the heat today on the East Coast. Some of us are even writing about it. But this week will also be marred by unusually bad air quality in the Eastern U.S.—several cities hit Code Orange or Code Red for air quality, due to dangerously high levels of ozone and other pollutants. (Check out the nationwide levels here.) In cities like Philadelphia, residents are being advised to stay inside when possible and avoid exertion outdoors. For most of us a bad air day is a nuisance, but for those with asthma or other respiratory problems, air pollution can be life-threatening.So it was an appropriate day for the Obama Administration to take one of its strongest moves yet on air pollution. Today the Environmental Protection Agency (EPA) proposed new regulations that will target power plant pollution that crosses the borders of 31 eastern states and Washington, DC. Called the Clear Air Transport Rule, the new standards—when finalized next year—will significantly reduce sulfur oxide and nitrous oxides, two smog-causing pollutants, and lead to hundreds of billions of dollars in public health savings. The new rules could help avoid as many as 36,000 premature deaths a year by reducing air pollution. Millions of people continue to breathe unhealthy air that doesn t meet national air quality standards, said Gina McCarthy, EPA s assistant administrator for air and radiation,[url=http://www.lululemononsales.com]lululemon athletica[/url], in a press briefing today. Today marks a large and important step in EPA s effort to protect public health. The new rules take advantage of the good neighbor provision of the Clear Air Act to cut interstate transport—not cars and trucks, but the drift of air pollutants across state borders. (Air pollution, not unlike oil spills, does not respect the lines of the map.) It can be difficult for downwind states to meet air quality standards because of power plant pollution from upwind states—Pennsylvania, for instance, can t do much if power plants in more crowded New Jersey are spewing pollutants across the Delaware River. The new regulations will require cuts in power plant emissions that cross state borders, starting in 2012. The EPA expects that altogether we ll see a reduction in sulfur dixode of 71% by 2014 and a reduction in nitrogen oxide of 52%.Environmentalists and public health advocates were pleased with the new rules, but they ll keep pushing for tighter regulations on power plants and air pollution. Here s David Marshall, senior counsel for the Clean Air Task Force: A generation after passage of the landmark Clean Air Act,[url=http://www.lululemononsales.com]men s yoga clothing[/url], there is no reason that power plant pollution should not be tightly controlled. The control technology is widely available and very effective, and the environmental and public health benefits of controls that go beyond what the EPA proposes today vastRelated articles:
