Did you know that approximately 117 million people – over one-third of the total U.S. population – get some or all of their drinking water from public systems that rely in part on headwater, seasonal or rain-dependent streams?
“Human activities, a changing climate and natural disasters are rapidly altering the face of our planet. Now, with NASA’s Images of Change iPad application, users can get an interactive before-and-after view of these changes.” Quoted from the NASA press release.
“The U.S. Geological Survey recently completed an evaluation of the technically accessible storage resource for carbon dioxide for 36 sedimentary basins in the onshore areas and State waters of the United States.” Quoted from the USGS press release.
“Rain as acidic as undiluted lemon juice may have played a part in killing off plants and organisms around the world during the most severe mass extinction in Earth’s history.” Quoted from the MIT press release.
“Landscape change in Pennsylvania’s Sullivan, Wyoming, Armstrong and Indiana counties resulting from construction of well pads, new roads and pipelines for natural gas and coalbed methane exploration is being documented by the United States Geological Survey.” Quoted from the USGS announcement.
Christina Figueres, Executive Director of the UN Framework Convention on Climate Change, said… “It is abundantly clear that further capital expenditures on coal can only go ahead if they are compatible with the 2 degree Celsius limit.” Quoted from the United Nations News Center.
The Texas drought caused many drillers to reevaluate their sources of water. Many of them are now processing their water to remove dissolved and suspended materials and reusing it to fracture their next well.
“Rising global temperatures and changing human actions will significantly affect the behavior and distribution of mercury worldwide, according to a recent article by the U.S. Geological Survey and Harvard University.” Quoted from the USGS press release.
On Monday, the Glen Canyon Dam is scheduled to start releasing up to 37,200 cubic feet of water per second – that is an Olympic-sized swimming pool worth of water into the Colorado River every two minutes. The goal is to imitate a natural flood that will deliver sand to beaches and refresh river habitats.
In 1987, Thailand built a dam on the Khlong Saeng river. As the reservoir filled it transformed over 100 forested hilltops into islands. Now each island, along with its plant and animal inhabitants, is an experiment to test what happens with a forest environment is fragmented.
“Peru’s cloud forests are some of the most biologically diverse ecosystems in the world. Researchers have new evidence that shows rapid 21st century warming may spell doom for tree species in Peruvian cloud forests, with species losing 53 to 96 percent of their populations.” Quoted from the Wake Forest University press release.
“Acidification of the Arctic Ocean is occurring faster than projected. The increase in rate is being blamed on rapidly melting sea ice, a process that may have important consequences for health of the Arctic ecosystem.” Quoted from the USGS Newsroom.
“Take a look at groundwater with DCNR’s Bureau of Topographic & Geologic Survey’s Stuart Reese as he looks at how much groundwater Pennsylvania has, where it comes from, and why it’s so important to the water cycle.” Quoted from the iConservePA press release.
The Spring 2013 issue of Oceanus Magazine, published by Woods Hole Oceanographic Institution, is titled Fukushima and the Ocean. It looks at the triple disaster that hit Japan with an earthquake, a tsunami and a power plant failure.
“Scientists have discovered a vast plume of iron and other micronutrients more than 1,000 km long billowing from hydrothermal vents in the South Atlantic Ocean. The finding [...] calls past estimates of iron abundances into question, and may challenge researchers’ assumptions about iron sources in the world’s seas.” Quoted from the Woods Hole Oceanographic Institution press release.
