Topic : carbon-dioxide EPA designates greenhouse gases a public health threatDecember 7th, 2009 By Harriet Blake In what might seem a no-brainer, the Environmental Protection Agency on Monday pronounced greenhouse gases to be a verifiable public health threat to all Americans. The announcement came on the first day of the Copenhagen Climate Conference and after what the EPA describes as a “thorough examination of the scientific evidence” required by government rules as the agency prepares to set standards for “light-duty vehicles.” Related Topics: · Carbon Dioxide, carbon pollution, climate talks, Copenhagen, EPA, GHGs, Greenhouse Gases The case for 350 and a call to actionOctober 15th, 2009 By Barbara Kessler Related Topics: · 350, 350.org, BarbaraKesslerBlog, Carbon Dioxide, International Day of Climate Action Try Sierra Club’s virtual frying pan to count your carbon footprintAugust 12th, 2009 By Melissa Segrest Shall we have an omelet with vegetables and cheese for breakfast?
Let’s order a Caesar salad for lunch, with some chicken noodle soup. And dinner – Who’s up for meatloaf, with macaroni and cheese on the side and some chocolate chip cookies to top it off? Oh, while you’re at it, stop for a second and ask yourself: What impact does this food have on the environment? Here’s some food for thought: An entertaining interactive tool lets you add up your “carbon points” and see just how badly those three cups of coffee are hurting the world.

The phenomenon is not unique. Trees and plants absorb some carbon. The ocean absorbs carbon. But trees can only do so much, and when they die, they release the carbon back into the atmosphere. The ocean has limits as well; it is already becoming acidic as gobbles our thickening stream of pollution. Rocks, though, can capture carbon and render it into a solid, where it is virtually inert.

The changing schedules of fall foliage may be a headache for nature lovers who time their forest vacations to maximize viewing of autumnal reds and oranges. But they could be good for the environment those travelers set out to enjoy. According to a new article in the journal Global Change Biology, a team led by Michigan Tech forestry professor David F. Karnosky has established that increased levels of atmospheric CO2 “act directly to delay the usual autumn spectacle of changing colors and falling leaves in northern hardwood forests.” Related Topics: · Carbon Dioxide, Travel, Trees |
