Wind may be the usual suspect for knocking down trees during hurricanes, but a new survey of forest damage in Puerto Rico after back-to-back hurricanes in 2017 highlights the power of a strong downpour. When Hurricane Irma passed off the coast of Puerto Rico on September 6, 2017, the storm brought heavy rains but minimal […] More
Rising seas that swamp cities and coastal infrastructure could cost the world more than 4 percent of the global economy each year by 2100 — far more than previously estimated — unless urgent action is taken both to reduce greenhouse gas emissions and to prepare for such impacts from climate change, a new study finds. […] More
Using fossil fuels releases much more of the potent greenhouse gas methane than previously thought — possibly 25 to 40 percent more, new research suggests. The finding could help scientists and policy makers target how and where to reduce these climate-warming emissions, researchers report February 19 in Nature. The amount of methane released from geologic […] More
SEATTLE — Human bodies make great worm food. That’s the conclusion of pilot experiments with six dead bodies that were allowed to decompose among wood chips and other organic material. The results, presented February 16 at the annual meeting of the American Association for the Advancement of Science, suggest that composting, also called natural organic […] More
Getting set for a black gold rush, Science News, February 14, 1970 — Nobody has ever done what the engineers designing the Trans-Alaska Pipeline are faced with: the need to carry hot oil through the Arctic. The Trans-Alaska Pipeline, expected to be completed in 1972, will carry 600,000 barrels of oil a day across Alaska. […] More
Nearly a decade after the Deepwater Horizon oil spill in the Gulf of Mexico, computer simulations suggest that the toxic pollution extended much farther than satellite images first indicated. Those images, taken after the spill dumped nearly 800 million liters of oil into Gulf waters, helped to determine which areas would be temporarily closed […] More
The noise of shipping vessels traveling through northern Canadian waters is causing Arctic cod to sacrifice much of their foraging and feeding in order to flee the area until ships move away, researchers report. The findings — the first to gauge how shipping noise could affect Arctic fish — are cause for concern as climate […] More
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
