That ‘Methane Time Bomb’ now lurks behind dams

From the American Chemical Society. I wonder if they studied how much methane comes from sediment loads dropped by rivers naturally and compared them? The Mississippi Delta alone must be a terrible offender. Sediment trapped behind dams makes them ‘hot spots’ for greenhouse gas emissions With the “green” reputation of large hydroelectric dams already in…

In a new study, James Hansen pushes nuclear power as saving more lives than it has harmed

This is sure to get some enviros in a tizzy. From Chemical and Engineering News of the American Chemical Society: Nuclear Power Prevents More Deaths Than It Causes Climate Change: Study estimates that nuclear energy leads to substantially fewer pollution-related deaths and greenhouse gas emissions compared with fossil-fuel sources By Mark Schrope Using nuclear power…

Plants: An efficient green technology for cities

From the American Chemical Society Green plants reduce city street pollution up to 8 times more than previously believed Trees, bushes and other greenery growing in the concrete-and-glass canyons of cities can reduce levels of two of the most worrisome air pollutants by eight times more than previously believed, a new study has found. A…

Caution needed with new greenhouse gas emission standards

From the University of Calgary New model provides lifecycle analysis of ‘well-to-wheel’ oil sands emissions Policy makers need to be cautious in setting new ‘low-carbon’ standards for greenhouse gas emissions for oil sands-derived fuels as well as fuels from conventional crude oils University of Calgary and University of Toronto researchers say in a paper published…

Too many cooks spoil the carbon footprint

From the American Chemical Society  it seems that newer is not always better. Even Yale environment360 bought into this idea. I should add that I’m all for reducing carbon soot, but in the zealous rush for solutions, sometimes too many cooks spoil the soup. Right: Primitive stoves and open fires pose serious health risks, particularly…
