NOAA today released for public comment a draft environmental impact statement (DEIS) and proposed rule for expanding the boundaries of Thunder Bay National Marine Sanctuary in Lake Huron from its current 448 square miles to 4,300 square miles.
Air pollution is related to forest decline and also appears to attack the protecting wax on tree leaves and needles. Scientists have now discovered a responsible mechanism: particulate matter salt compounds that become deliquescent because of humidity and form a wick-like structure that removes water from leaves and promotes dehydration.
Technological innovation during the Stone Age occurred in fits and starts and was climate-driven, according to new research. Abrupt changes in rainfall in South Africa 40,000 to 80,000 years ago triggered the development of technologies for finding refuge and the behavior of modern humans.
A new study shows that the predator-prey relationship can affect the flow of carbon through an ecosystem. This previously unmeasured influence on the environment may offer a new way of looking at biodiversity management and carbon storage for climate change.
