Lake Mead water levels continuing to drop
April 19, 2015 07:45 AM - Kirk Siegler/NPR

The historic four-year drought in California has been grabbing the headlines lately, but there's a much bigger problem facing the West: the now 14-year drought gripping the Colorado River basin.

One of the most stunning places to see its impact is at the nation's largest reservoir, Lake Mead, near Las Vegas. At about 40 percent of capacity, it's the lowest it's been since it was built in the 1930s.

Think Different: Apple and conservation
April 17, 2015 07:14 AM - Andrew Burger, Triple Pundit

Marking a precedent-setting conservation partnership, Apple and the Conservation Fund will purchase two large areas of working forest, the organizations announced on Thursday. The move is expected to conserve “more than 36,000 acres of working forestland in Maine and North Carolina, ensuring these forests stay forests and any timber on the land is harvested sustainably,” the partners said in a joint announcement.

This initial purchase of U.S. working forestland marks “the beginning of a worldwide effort, one that represents a new approach as it reassesses its impact on the world’s paper supply chain,” Lisa P. Jackson, Apple’s vice president of environmental initiatives, and Larry Selzer, president and CEO of the Conservation Fund, wrote in a Medium op-ed. Prior to joining Apple, Jackson led the U.S. EPA as President Barack Obama’s EPA Administrator from 2009 to 2013.

How California distributes scarce water
April 15, 2015 08:09 AM - Dan Charles, NPR

The state of California is asking a basic question right now that people often fight over: What's a fair way to divide up something that's scarce and valuable? That "something," in this case, is water.

There's a lot at stake, including your very own nuts, fruit and vegetables, because most of the water that's up for grabs in California goes to farmers. This year, some farmers will get water, and others will not, simply based on when their land was first irrigated.

Consider, for instance, the case of Cannon Michael. He grows tomatoes and melons in California's Central Valley. And despite the drought, he'll still grow them this year.

The impact levees have on groundwater recharge
April 12, 2015 08:54 AM - Kat Kerlin, UC Davis News Service via ECOreport

Strange as it sounds, flood control can be part of the solution to managing California’s droughts. University of California scientists have shown that making more room for floodwaters can improve the state’s groundwater supplies and fisheries.

Removing some levees or rebuilding aging ones some distance away from riverbanks can appreciably replenish aquifers during wet years, providing some relief during droughts.

Record low snowpacks in Southwest is bad news for water supplies
April 11, 2015 07:57 AM - Roy L Hales, the ECOreport

Nine states report record low snowpacks. A report from the US Department of Agriculture states, “the largest snowpack deficits are in record territory for many basins,especially in the Cascades and Sierra Nevada where single – digit percent of normal conditions prevail. Very low snowpacks are reported in most of Washington, all of Oregon, Nevada, California, parts of Arizona, much of Idaho, parts of New Mexico, three basins in Wyoming, one basin in Montana, and most of Utah.” This region is undergoing the warmest winter temperatures since record keeping began in 1895.

New strategy will help save declining ape population
April 10, 2015 12:35 PM - WWF Global

The number of gorillas and chimpanzees in Central Africa continues to decline due to poaching, habitat loss and disease according to a new plan published by WWF, International Union for Conservation of Nature, Wildlife Conservation Society and partners. The strategy, “Regional Action Plan for the Conservation of Western Lowland Gorillas and Central Chimpanzees 2015-2025”—outlines the growing number of threats to these great apes across six range countries, including gaps in law enforcement and the threats by well-connected traffickers seeking to supply the illegal commercial market.

Neonicotinoids Responsible for Pollinator Declines Worldwide
April 9, 2015 02:46 PM - Jonathan Latham, The Ecologist

Monarch caterpillars are vulnerable to neonicotinoid toxicity at concentrations as low as 1 part per billion, writes Jonathan Latham, and that makes them vulnerable to residues from commercial crops - and even more so from horticultural use in plant nurseries!

New report identifies possible next steps in US energy development
April 9, 2015 10:09 AM - American Geosciences Institute via EurekAlert!

The U.S. energy portfolio changes over time. Scientific and technologic advances related to hydraulic fracturing have dramatically increased the supply of U.S. oil and gas; because of this, a methane economy - in which natural gas provides the leading share of primary energy consumption - is now a possible scenario for U.S. energy development. In a report released by the American Geosciences Institute (AGI), the social, political, technical and environmental components of a methane economy are identified. The report also addresses how industry, government and the public might best work together to advance common energy goals.

Fracking appears to be linked to rise in radon levels in Pennsylvania homes
April 9, 2015 06:35 AM - JOHNS HOPKINS UNIVERSITY BLOOMBERG SCHOOL OF PUBLIC HEALTH, via EurekAlert.

Johns Hopkins Bloomberg School of Public Health researchers say that levels of radon in Pennsylvania homes - where 42 percent of readings surpass what the U.S. government considers safe - have been on the rise since 2004, around the time that the fracking industry began drilling natural gas wells in the state.

The researchers, publishing online April 9 in Environmental Health Perspectives, also found that buildings located in the counties where natural gas is most actively being extracted out of Marcellus shale have in the past decade seen significantly higher readings of radon compared with buildings in low-activity areas. There were no such county differences prior to 2004. Radon, an odorless radioactive gas, is considered the second-leading cause of lung cancer in the world after smoking.
