A new study by NASA and University of California, Irvine, scientists finds more than 75 percent of the water loss in the drought-stricken Colorado River Basin since late 2004 came from underground resources. The extent of groundwater loss may pose a greater threat to the water supply of the western United States than previously thought.
This study is the first to quantify the amount that groundwater contributes to the water needs of western states. According to the U.S. Bureau of Reclamation, the federal water management agency, the basin has been suffering from prolonged, severe drought since 2000 and has experienced the driest 14-year period in the last hundred years.

New research reveals that off-shore wind farms are particularly useful for seals as they appear to act like artificial reefs, drawing in large groups of fish. The study, carried out by researchers at St Andrews University in Scotland and published this month in the journal Current Biology, saw scientists track a group of seals in the North Sea using GPS devices. The purpose of the study was to look at whether man-made changes to the structural ocean environment are affecting marine predator behavior.

The concept of a national carbon tax is a hard sell for most people these days. According to a recent poll, only 34 percent of U.S. respondents said they would support taxing fossil fuels like oil, gas or natural gas. But support for a carbon tax changes dramatically when it comes to scenarios in which the funds are either reimbursed to taxpayers or used to fund renewable energy projects.

The National Marine Fisheries Service opened a public process today to determine whether to prohibit fishing for Pacific bluefin tuna, which have suffered a 96 percent decline since large-scale fishing began. The action followed the Center for Biological Diversity’s rulemaking petition sent in April.
The Pacific bluefin population’s historic low triggered a requirement for new regulations to better manage overfishing by April 8, 2014, but regulators thus far have declined to take any steps to help the fish. Today’s request for comments is the federal government’s first step to spur action from the Pacific Fishery Management Council.
