  3. Ocean Gases not a Contributor to Climate Change
    April 24

    There are fears that stores of the gas trapped at the bottom of the ocean could be awakened by warming temperatures, but researchers are helping to show that might not be the case. (Australian Broadcasting Corporation) more...

  4. Can Trees Save us From Climate Change?
    April 24

    Trees do a lot for us: provide wood, improve health, even clean up the air by chemically converting CO2 to carbohydrates, but the answer to climate change is not as simple as planting more trees. (Scientific American) more...

  5. Ozone Layer Faces Bumpy Return to Health
    April 23

    The Earth's ailing ozone layer will probably recover, but it will never look exactly like it used to, according to a new study that found that greenhouse gasses are interfering with ozone's rebound in complicated ways. (Discovery news) more...
