    Fossil fuel use may emit 40 percent more methane than we thought

    Using fossil fuels releases much more of the potent greenhouse gas methane than previously thought — possibly 25 to 40 percent more, new research suggests.

    Climate change may be speeding up ocean circulation

    Winds are picking up worldwide, and that is making the surface waters of the oceans swirl a bit faster, researchers report. A new analysis of the ocean’s kinetic energy, measured by thousands of floats around the world, suggests that surface ocean circulation has been accelerating since the early 1990s. Some of that sped-up circulation may […] More

    50 years ago, scientists puzzled over a slight global cooling

    Earth’s cooling climate, Science News, November 15, 1969 — The average temperature for the entire Earth rose gradually from the 1880s until the early 1940s. At that time, a cooling trend suddenly set in which is continuing today.… The amount of dust and other particulate matter in the atmosphere has increased dramatically in recent decades, […] More

    How climate change is already altering oceans and ice, and what’s to come

    Polar caps quickly losing ice. Chalky coral reefs. Stronger storms that devastate islands and cities, claiming lives and destroying homes. Those aren’t speculations about what our world faces in a warmer future. Those are climate change impacts happening now — and set to worsen, according to a new report by the U.N. Intergovernmental Panel on […] More
