The Fukushima Accident Lives On
August 18, 2015 12:14 PM - Dr Ian Fairlie, The Ecologist
New evidence from Fukushima shows that as many as 2,000 people have died from necessary evacuations, writes Ian Fairlie, while another 5,000 will die from cancer. Future assessments of fatalities from nuclear disasters must include deaths from displacement-induced ill-heath and suicide in addition to those from direct radiation impacts.
Dissecting the Farm-to-Table Fable
August 18, 2015 09:17 AM - Jan Lee, Triple Pundit
The vibrant, mega-million-dollar farm to table movement is under increasing scrutiny these days. In San Diego, where produce is an $1.8 billion industry and year-round farmers markets can be found in almost every neighborhood (one of the few financial spinoffs of climate change, perhaps), the farm-to-table concept is getting a bad rep.
Long term ocean cooling ended with global warming
August 18, 2015 07:18 AM - University of Maryland via EurekAlert
Prior to the advent of human-caused global warming in the 19th century, the surface layer of Earth's oceans had undergone 1,800 years of a steady cooling trend, according to a new study. During the latter half of this cooling period, the trend was most likely driven by large and frequent volcanic eruptions.
An international team of researchers reported these findings in the August 17, 2015 issue of the journal Nature Geoscience. The study also indicates that the coolest temperatures occurred during the Little Ice Age--a period that spanned the 16th through 18th centuries and was known for cooler average temperatures over land.
High levels of natural uranium identified in 2 major U.S. aquifers
August 17, 2015 03:30 PM - University of Nebraska-Lincoln
Nearly 2 million people throughout the Great Plains and California live above aquifer sites contaminated with natural uranium that is mobilized by human-contributed nitrate, according to a study from the University of Nebraska-Lincoln.
Quantifying CO2 from Streams

Work by a University of Wyoming professor and a recent UW Ph.D. graduate has provided a more complete picture of the role of rivers and streams in the global carbon cycle.
Neighborhood electric vehicles
August 17, 2015 07:23 AM - BOB SHETH, Electric Forum
While much of the focus of late has been upon mainstream electric vehicles it seems as though the popularity of Neighborhood electric vehicles continues to grow. These vehicles have a history which is far more successful than there larger electric vehicle counterparts but receive very little in the way publicity or promotion. The Global Electric Motor (GEM) brand is by far and away the best known brand in this particular sector having changed hands on numerous occasions in the past.
So, why is it that NEVs continue to sneak under the radar yet gain in popularity?
Commentary on the US plan to reduce carbon emissions
August 16, 2015 07:45 AM - Tim Kruger, The Ecologist
President Obama's plan to cut greenhouse gas emissions may look like a climate victory, writes Tim Kruger - but it's no such thing. It's feeble because the US can meet its targets by reducing emissions to 2030 more slowly than it has since 2000. And it's fragile as any future President can scrap it at will.
Climate change-denying Republicans hate this plan (of course), therefore all good climate realists see it as a triumph. But it is a tiny, tiny step in the right direction and climatically immaterial.
No doubt, you heard the good news. Barack Obama has announced the US is pushing through plans to reduce emissions of greenhouse gases. Rejoice! Rejoice! We've got this climate problem licked - hurrah!
US EPA proposes regulations to reduce methane emissions from landfills
August 15, 2015 07:53 AM - US Environmental Protection Agency
As part of the Administration's Climate Action Plan – Strategy to Reduce Methane Emissions, the U.S. Environmental Protection Agency (EPA) issued two proposals to further reduce emissions of methane-rich gas from municipal solid waste (MSW) landfills. Under today’s proposals, new, modified and existing landfills would begin collecting and controlling landfill gas at emission levels nearly a third lower than current requirements.
Methane is a potent greenhouse gas with a global warming potential more than 25 times that of carbon dioxide. Climate change threatens the health and welfare of current and future generations. Children, older adults, people with heart or lung disease and people living in poverty may be most at risk from the health impacts of climate change. In addition to methane, landfills also emit other pollutants, including the air toxics benzene, toluene, ethylbenzene and vinyl chloride.
Which food wastes have greater environmental impacts?
August 14, 2015 11:39 AM - University of Missouri-Columbia
Approximately 31 percent of food produced in the U.S., or 133 billion pounds of food worth $162 billion, was wasted in 2011 according to the United States Department of Agriculture (USDA). Now, University of Missouri researchers have found that the type of food wasted has a significant impact on the environment. Although less meat is wasted (on average) compared to fruits and vegetables, the researchers found that significantly more energy is used in the production of meat compared to the production of vegetables. This wasted energy is usually in the form of resources that can have negative impacts on the surrounding environment, such as diesel fuel or fertilizer being released into the environment.
Long-term Protection Achieved for the Sumatran Forest
August 14, 2015 07:59 AM - WWF Global
One of the last places on Earth where Sumatran elephants, tigers and orangutans coexist in the wild has received long-term protection. The Indonesian Ministry of Forestry approved a conservation concession – a lease of the land – covering 40,000 hectares of forest on the island of Sumatra.
