The problem with older thermostats - Mercury
January 15, 2014 07:51 AM - NRDC

NRDC Study Shows More Than 1.8 Million Thermostats Containing 8 Tons of Mercury Need Safe Recycling In Illinois. The state should raise collection goals for mercury-laden thermostats to avoid contaminating the environment. There are more than 1.8 million thermostats containing eight tons of mercury in Illinois homes and buildings, according to a study by the Natural Resources Defense Council and Clean Water Fund, which are calling for stronger state rules this year to speed up safe recycling of these thermostats.

Economic benefits of reducing nitrogen pollution
January 14, 2014 08:14 AM - Tom Marshall, Planet Earth Online

Falling levels of nitrogen in the atmosphere across Europe may be much more economically beneficial than previously believed, according to a recent study. Indeed, scientists think the UK alone benefits by around £65 million a year. Levels of atmospheric nitrogen have fallen by around a quarter in Europe since 1990, mostly because of tighter rules on emissions from engines and industry. Scientists are still working to understand the consequences. This is difficult, because excess nitrogen affects the benefits that nature gives us (known as 'ecosystem services') in many different ways – some positive and some harmful. For example, nitrogen is an important plant nutrient, which means services that depend on plant growth, such as crops and timber from woodlands, will benefit from more of it in the atmosphere. Conversely, falling nitrogen levels will harm these services - so cutting pollution costs the economy money.

Popularity of plug-in vehicles on the rise
January 13, 2014 09:30 AM - Eric Justian, Triple Pundit

Good news for those living at the intersection of manufacturing and environmentalism. Here in the U.S., sales of plug-in electric and hybrid vehicles almost doubled between 2012 and 2013 with an 84 percent jump to 96,600 of the vehicles sold. That’s 49,000 plug-in hybrids (like the Volt) and 47,600 pure battery powered plug-in vehicles sold.

How plants respond to climate change
January 12, 2014 08:24 AM - ScienceDaily

Swiss plants, butterflies and birds have moved 8 to 42 meters uphill between 2003 and 2010, as scientists from the University of Basel write in the online journal PLoS One. Climate warming is changing the distribution of plants and animals worldwide. Recently it was shown that in the past two decades, European bird and butterfly communities have moved on average 37 and 114 kilometers to the north, respectively.

EPA's New Greenhouse Gas Emissions Standards Now Open for Public Comment
January 10, 2014 02:39 PM - Andrew Burger, Triple Pundit

Politically contentious as ever, climate change is back in the headlines, as a brutal, deep and prolonged southward shift in the polar vortex has put much of the continental U.S. in a deep freeze. In stark contrast, people living in the Southern Hemisphere – in Australia, Argentina and Brazil, for example – are trying to cope with heat waves, the threat of drought and power outages in major cities. While many are scrambling with the immediacy of such problems, the U.S. Environmental Protection Agency (EPA) is moving forward with longer term, structural fixes to address climate change conceived by the Obama Administration. On Jan. 8, the EPA issued proposed new performance standards that would put an upper limit, or cap, on carbon and greenhouse gas (GHG) emissions from new, stationary power plants under Section 111 of the Clean Air Act.

State Officials Warn Climate Impact Predictions may be Worsening
January 10, 2014 10:27 AM - Tim Faulkner, ecoRI News

The situation looks grim for Rhode Island and the rest of the East Coast when it come to climate change. In fact, the outlook is getting worse, according to state officials. Grover Fugate, head of the Rhode Island Coastal Resources Management Council (CRMC) and the face of the state’s climate research and planning, recently said climate change is happening faster than scientists can model it.

Tree Island restoration
January 10, 2014 09:06 AM - Liz Kimbrough, MONGABAY.COM

Worldwide, large swaths of land lay barren in the wake of agricultural expansion, and as global forest cover continues to decline, carbon and water cycles, biodiversity, and human health are impacted. But efforts to restore abandoned pastures and agricultural plots back into functioning forest ecosystems are often hindered by high costs and time requirements. Fortunately, scientists have developed a new method for a more cost effective solution to forest restoration, the establishment of "tree islands."

West African Lion Faces Extinction
January 10, 2014 09:04 AM - ENN Staff

To many, the mighty lion is the face of African wildlife and one of the most recognized predators across the world. But despite sitting on top of the food chain, the lion is a vulnerable species and a new report concludes that the African lion is facing extinction across the entire West African region. The new study reveals that the West African lion is down to a population estimated at 250, and these individuals are restricted to four isolated populations.

Spitting Sulfates!
January 9, 2014 10:41 AM - Nicole Jones, Yale 360

In 1991, Mount Pinatubo in the Philippines erupted in one of the largest volcanic blasts of the 20th century. It spat up to 20 million tons of sulfur into the upper atmosphere, shielding the earth from the sun's rays and causing global temperatures to drop by nearly half a degree Celsius in a single year. That's more than half of the amount the planet has warmed due to climate change in 130 years.

Giant wave of understanding in South China Sea
January 8, 2014 03:43 PM - David L. Chandler, MIT

Their effect on the surface of the ocean is negligible, producing a rise of just inches that is virtually imperceptible on a turbulent sea. But internal waves, which are hidden entirely within the ocean, can tower hundreds of feet, with profound effects on the Earth's climate and on ocean ecosystems. Now new research, both in the ocean and in the largest-ever laboratory experiments to investigate internal waves, has solved a longstanding mystery about exactly how the largest known internal waves, in the South China Sea, are produced. The new findings come from a team effort involving MIT and several other institutions, and coordinated by the Office of Naval Research (ONR).
