Save the Bluefin Tuna
July 24, 2014 08:23 AM - Center for Biological Diversity
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.
New Poll Shows Support for Carbon Tax, with Exceptions
July 24, 2014 08:01 AM - Jan Lee, Triple Pundit
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.
Climate warming may not drive net losses of soil carbon from tropical forests
July 23, 2014 12:16 PM - Carnegie Institute for Science
The planet's soil releases about 60 billion tons of carbon into the atmosphere each year, which is far more than that released by burning fossil fuels. This happens through a process called soil respiration. This enormous release of carbon is balanced by carbon coming into the soil system from falling leaves and other plant matter, as well as by the underground activities of plant roots.
Wind energy not growing in Europe as quickly as expected
July 23, 2014 11:30 AM - EurActiv
Europe's installed wind capacity will increase at a slower rate to the end of the decade than previously estimated, due to regulatory uncertainty and weak economic growth, an industry association said on Wednesday (23 July). European Union countries will have a combined 192.4 gigawatts (GW) of installed wind energy capacity by 2020, 64% higher than 2013 levels, the European Wind Energy Association (EWEA) said in a report.
Do animal parents stress out like humans?
July 23, 2014 08:06 AM - Tamera Jones, Planet Earth Online
As every parent knows, bringing up children can be a draining business. Now researchers have found that banded mongoose parents find it so stressful, they have no energy left to care for the next litter. It seems the energetic demands of caring for pups pushes up the mongooses' stress hormone levels.
Wooly Mammoths and Mastodons loved Cincinnati!
July 22, 2014 04:47 PM - University of Cincinnati via ScienceDaily
Their scruffy beards weren't ironic, but there are reasons mammoths and mastodons could have been the hipsters of the Ice Age. According to research from the University of Cincinnati, the famously fuzzy relatives of elephants liked living in Greater Cincinnati long before it was trendy -- at the end of the last ice age. A study led by Brooke Crowley, an assistant professor of geology and anthropology, shows the ancient proboscideans enjoyed the area so much they likely were year-round residents and not nomadic migrants as previously thought.
Size and Age of Plants Impact Their Productivity More Than Climate
July 22, 2014 12:27 PM - University of Arizona
The size and age of plants have more of an impact on their productivity than temperature and precipitation, according to a landmark study by University of Arizona researchers. UA professor Brian Enquist and postdoctoral researcher Sean Michaletz, along with collaborators Dongliang Cheng from Fujian Normal University in China and Drew Kerkhoff from Kenyon College in Gambier, Ohio, have combined a new mathematical theory with data from more than 1,000 forests across the world to show that climate has a relatively minor direct effect on net primary productivity, or the amount of biomass — wood or any other plant materials — that plants produce by harvesting sunlight, water and carbon dioxide.
New research compares environmental costs of livestock-based foods
July 22, 2014 08:00 AM - Allison Winter, ENN
Trust me, no one loves a nice, big, juicy steak more than me and while I have no immediate plans of becoming a vegetarian, I am a little concerned about the resources and costs it takes to produce the proteins of our favorite meals. From the land that is used by livestock to the supplies and energy it takes to raise these animals for our consumption, it is evident that environmental resources take a toll. But what is the real cost? New research at the Weizmann Institute of Science, conducted in collaboration with scientists in the US, calculates these environmental costs and compares various animal proteins to give a multi-perspective picture of what resources are really being used.
NASA getting ready to test engines for Space Launch System rocket
July 22, 2014 07:32 AM - Roger Greenway, ENN
Since the end of the Space Shuttle flights, NASA has been relying on help from Russia to launch men and women into space. The agency has been planning on replacement rockets to take humans into space and now engineers have taken a crucial step in preparing to test parts of NASA's Space Launch System (SLS) rocket that will send humans to new destinations in the solar system. They installed on Thursday an RS-25 engine on the A-1 Test Stand at the agency's Stennis Space Center near Bay St. Louis, Mississippi.
Devil Rays are deep divers!
July 21, 2014 03:23 PM - Woods Hole Oceanographic Institution
Thought to dwell mostly near the ocean's surface, Chilean devil rays (Mobula tarapacana) are most often seen gliding through shallow, warm waters. But a new study by scientists at Woods Hole Oceanographic Institution (WHOI) and international colleagues reveals that these large and majestic creatures are actually among the deepest-diving ocean animals. "So little is known about these rays," said Simon Thorrold, a biologist at WHOI and one of the authors of the paper, published July 1, 2014, in the journal Nature Communications. "We thought they probably travelled long distances horizontally, but we had no idea that they were diving so deep. That was truly a surprise."
