  • U.S. Carbon Dioxide Emissions Down 11 Percent Since 2007

    Carbon dioxide emissions from burning fossil fuels in the United States peaked at more than 1.6 billion tons of carbon in 2007. Since then they have fallen 11 percent, dropping to over 1.4 billion tons in 2013, according to estimates from the U.S. Energy Information Administration. Emissions shrank rapidly during the recession, then bounced back slightly as the economy recovered. But shifting market conditions, pollution regulations, and changing behaviors are also behind the decline. More

  • Wind Power Facts: Emissions Through the Lifecycle

    A recent scholarly paper decided to tackle the problem of the emissions of wind power, wishing to quantify the actual emissions so as to make accurate comparisons between wind power and other sources of electrical power generations. More

  • More Evidence of the Importance of Forests: They’re Even Bigger Carbon Sinks than Thought

    Want to see clear connections between environmental degradation and economic struggles? Deforestation provides about as clear a picture as any example: the loss of ecological services (flood control, water and air purification, topsoil protection, etc.) have direct economic impacts ranging from disaster recovery costs to food prices to increased need for health care spending. And, […] More

  • Mutation of Plants Could be Key to Drought Tolerance

    Researchers have found a plant with a genetic mutation that allows it to survive drought better without losing any mass. This discovery could potentially lead to plants that are bred to survive in low-water conditions, perhaps reducing the amount of water used for agriculture. More

  • Online Shopping: How Green is It?

    The Online Shopping Survey conducted by GfK in 2008 showed that about 70 % of people think shopping online is good for the environment as it helps to reduce the carbon footprint. But is it really that simple? Too many variables come in to play: when you live, how much you buy, who delivers the […] More

    Top Global Warming Causes – Natural or Human?

    If you’ve followed the debate over climate change even a little, you likely know the main causes of global warming: concentrations of greenhouse gases build up in the Earth’s atmosphere, and create a “greenhouse,” or warming effect. You’re likely also aware that evidence of past warming periods has fueled the argument that natural causes are […] More

  • Prevention of Global Warming: Understanding The Main Causes

    With Congress deep in debate over legislation aimed at the prevention of global warming, and skeptics ramping up their rhetoric, it seemed like a good time to take a step back to some basics — more accurate information is critical here. Step one in figuring in out how we can help in the battle against […] More

  • SolveClimate: Tom Delay & the EPA

    Editor’s note: This post was originally published on Friday, April 17, at SolveClimate. EPA Administrator Lisa Jackson announced today that she has determined that greenhouse gas emissions pose a danger to the public health and welfare. The next step is a 60-day comment period, but once that endangerment finding becomes official, it will mark a […] More

  • Environmental Defense Fund: Global Warming by the Numbers – 13 Scary Facts

    Friday the 13th just got a little scarier. Here are 13 facts about the realities of global warming. The numbers speak for themselves — we must make 2009 the showdown year for global warming action. There is no time to lose. 35% Increase in the global carbon dioxide emissions from the burning of fossil fuels […] More

  • Earth Policy Institute: Restructuring the U.S. Transport System — The Potential of High-Speed Rail

    By Lester R. Brown Aside from the overriding need to stabilize atmospheric carbon dioxide (CO2) levels to stabilize climate, there are several other compelling reasons for countries everywhere to restructure their transport systems, including the need to prepare for falling oil production, to alleviate traffic congestion, and to reduce air pollution. The U.S. car-centered transportation […] More

  • Japan Launches First Satellite to Monitor Greenhouse Gases Worldwide

    The Japanese government has launched the first satellite to monitor greenhouse gases worldwide. This tool will help scientists better ascertain where global warming emissions are coming from and how much is being absorbed by the oceans and forests. The U.S. will launch a similar orbiter next month. More
