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.

Study shows how climate affects biodiversity
April 16, 2015 03:18 PM - Uppsala University via AlphaGalileo

A key question in the climate debate is how the occurrence and distribution of species is affected by climate change. But without information about natural variation in species abundance it is hard to answer. In a major study, published today in the leading scientific journal Current Biology, researchers can now for the first time give us a detailed picture of natural variation.

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 importance of oceanic phytoplankton
April 14, 2015 07:52 AM - Roger Greenway, ENN

Do you have any idea just how many organizims are in seawater?  Not the fish you can see, but the microscopic organizims you cant see?

Dip a beaker into any portion of the world’s oceans, and you’re likely to pull up a swirling mix of planktonic inhabitants. The oceans are teeming with more than 5,000 species of phytoplankton — microscopic plants in a kaleidoscope of shapes and sizes. Together, phytoplankton anchor the ocean’s food chain, supplying nutrients to everything from single-celled organisms on up to fish and whales.

Through photosynthesis, these tiny organisms supply more than half the world’s oxygen. When these plants die, they drift to the ocean bottom, or evaporate into the air as carbon — a process that generates more than half the world’s cycling carbon.

Warmer Waters Threaten Future of Traditional Fish and Chips
April 13, 2015 03:02 PM - ClickGreen Staff, ClickGreen

Popular North Sea fish such as haddock, plaice and lemon sole could be replaced on the menus of the nation’s fish and chip shops as the seas around the UK continue to warm at a rapid rate, a new study warns. Fish distributions are limited by water temperature and some species can only thrive in certain habitats and depths. 

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.

Mercury levels in Arctic birds found increasing over the past 130 years
April 10, 2015 09:08 AM - Population Matters

Alarm bells are ringing for Arctic wildlife with the discovery that mercury levels in the feathers of ivory gulls have increased almost 50-fold. 

University of Saskatchewan biologists studied the feathers of museum specimens spanning a 130-year period. Lead researcher Dr Alex Bond told BBC News, “We’re concerned because the mercury’s going up but their diet hasn’t changed over the 130 years we’ve studied. It’s gone up 45 times, which is twice the average for an animal species in the Arctic.”

What is the source of mysterious methane emissions at Four Corners?
April 8, 2015 08:20 AM - University of Colorado Boulder

A team of scientific investigators is now in the Four Corners region of the U.S. Southwest, aiming to uncover reasons for a mysterious methane hotspot detected from space by a European satellite. The joint project is working to solve the mystery from the air, on the ground, and with mobile laboratories. 

“If we can verify the methane emissions found by the satellite, and identify the various sources, then decision makers will have critical information for any actions they are considering,” says Gabrielle Pétron, a scientist from the Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder, working in NOAA’s Earth System Research Laboratory (ESRL) and one of the mission’s investigators. Part of President Obama’s recent Climate Action Plan calls for reductions in U.S. methane emissions. NOAA is the National Oceanic and Atmospheric Administration.

Early warning system to detect algal blooms being launched by EPA
April 7, 2015 03:24 PM - US EPA Newsroom

The U.S. Environmental Protection Agency (EPA) announced today that it is developing an early warning indicator system using historical and current satellite data to detect algal blooms. EPA researchers will develop a mobile app to inform water quality managers of changes in water quality using satellite data on cyanobacteria algal blooms from three partnering agencies-- NASA, NOAA, and the U.S. Geological Survey. 

The multi-agency project will create a reliable, standard method for identifying cyanobacteria blooms in U.S. freshwater lakes and reservoirs using ocean color satellite data. Several satellite data sets will be evaluated against environmental data collected from these water bodies, which allows for more frequent observations over broader areas than can be achieved by taking traditional water samples.
 

Sun experiences seasonal changes
April 7, 2015 09:35 AM - UCAR AtmosNews

The Sun undergoes a type of seasonal variability, with its activity waxing and waning over the course of nearly two years, according to a new study by a team of researchers led by the National Center for Atmospheric Research (NCAR). This behavior affects the peaks and valleys in the approximately 11-year solar cycle, sometimes amplifying and sometimes weakening the solar storms that can buffet Earth’s atmosphere.
