Scientists Urge Focus On New Branch Of Environmental Health
2013-11-20 09:49:14

Wildlife Conservation Society A new paper from members of the HEAL (Health & Ecosystems: Analysis of Linkages) consortium delineates a new branch of environmental health that focuses on the public health risks of human-caused changes to Earth's natural systems. Looking comprehensively at available research to date, the paper's authors highlight repeated correlations between changes in natural systems and existing and potential human health outcomes, including: Forest fires used...

Ship Noise Makes Crabs Cranky
2013-02-27 15:07:13

Brett Smith for redOrbit.com - Your Universe Online Private industry rarely has a stake in conservation, but a new study shows that reducing aquatic noise pollution could provide a financial boost for the fishing industry. A new study published in the journal Biology Letters found that the sounds of ship noise ramp up crab metabolism, potentially resulting in lower yields for commercial crabbers. Citing growing evidence that shows even a single noise exposure can affect a variety...

Climate change and extreme weather events grab the headlines, but there is another, lesser known, global change underway on land, in the seas, and in the air: acidification. It turns out that combustion of fossil fuels, smelting of ores, mining of coal and metal ores, and application of nitrogen fertilizer to soils are all driving down the pH of the air, water, and the soil at rates far faster than Earth's natural systems can buffer, posing threats to both land and sea life. "It's a...

Anthropocene Continues To Instigate Scientific Debate
2012-11-01 13:07:36

Geological Society of America GSA Annual Meeting Technical Session: "Geomorphology of the Anthropocene" How have humans influenced Earth? Can geoscientists measure when human impacts began overtaking those of Earth's other inhabitants and that of the natural Earth system? Responding to increasing scientific recognition that humans have become the foremost agent of change at Earth's surface, organizers of this GSA technical session have brought together speakers and poster presentations...

Ship engine exhaust emissions make up more than a quarter of nitrogen oxide emissions generated in the Australian region according to a recently-published study by CSIRO and the Australian Maritime College in Launceston. Nitrogen oxide is a non-greenhouse gas, unlike similarly named nitrous oxide. The remainder comes from road and air transport, energy generation, and industrial processes. Global studies indicate that shipping emissions of nitrogen oxide and sulphur contribute to the...
