Pollution

Oceanic litter is widespread
July 8, 2014 08:18 AM - Harriet Jarlett, Planet Earth Online

Litter is now found in even the most remote areas of the oceans, say scientists trying to understand how much rubbish is lying at the bottom of Europe's seas. The new study, published in Plos One, shows for the first time that there seems to be no area of the ocean left untouched by human litter. Using 588 video clips collected by unmanned submarine vehicles for geological mapping and marine biology studies, the team found that plastics waste like shopping bags is the most prevalent.

A Fine Line : New Program Predicts When Human Impact Becomes Too Much
July 6, 2014 10:25 AM - Morgan Erickson-Davis, MONGABAY.COM

Scientists at Stanford University recently unveiled a new modeling program that can predict the response of the environment to the land-use changes of human communities. Using their model, they found that natural resources can support humanity — up to a certain point. They recently published their findings in the journal Environmental Modelling & Software.

Frackable rock under groundwater aquifers raise water contamination fears
July 3, 2014 02:20 PM - Editor, The Ecologist

A study by the British Geological Survey and the Environment Agency reveals that almost all the the oil and gas bearing shales in England and Wales underlie drinking water aquifers, raising fears that widespread water contamination could occur. The British Geological Survey (BGS) in partnership with The Environment Agency (EA) have published a map which show the depth to each shale gas and oil source rock below principal groundwater aquifers in England and Wales.

Where's the Plastic?
July 3, 2014 08:49 AM - Kevin Mathews, Care2

According to a new study, 99% of plastic waste that enters the ocean cannot be located. While initially hearing that there's less plastic in the ocean than we believed sounds like great news, it's actually a frightening prospect. After all, if the plastic isn't in the ocean ... where is it going?! A team from the University of Western Australia spent a couple of years sailing around the world in five vessels hoping to accurately record just how much plastic is actually in the ocean. Although researchers expected to discover millions of tons, they were surprised to calculate that they only calculated about 40,000 tons of plastic floating on the surface.

EPA Proposes New Standards for Landfills, Hopes to Reduce Methane Emissions
July 2, 2014 08:49 AM - US EPA Newsroom

As part of the President's Climate Action Plan — Strategy to Reduce Methane Emissions, the U.S. Environmental Protection Agency (EPA) is proposing updates to its air standards for new municipal solid waste (MSW) landfills. These updates would require certain landfills to capture additional landfill gas, which would reduce emissions of methane, a potent greenhouse gas, and help further reduce pollution that harms public health.

Is Oceanic Plastic being eaten by fish?
July 1, 2014 07:38 AM - ANGUS CHEN, ScienceNOW

Millions of tons. That's how much plastic should be floating in the world's oceans, given our ubiquitous use of the stuff. But a new study finds that 99% of this plastic is missing. One disturbing possibility: Fish are eating it. If that’s the case, "there is potential for this plastic to enter the global ocean food web," says Carlos Duarte, an oceanographer at the University of Western Australia, Crawley. "And we are part of this food web."

EPA Proposes Approval of New Climate-Friendly Refrigerants
June 27, 2014 03:56 PM - USEPA Newsroom

In support of President Obama's Climate Action Plan, the U.S. Environmental Protection Agency (EPA) is proposing to increase the options for refrigerants in the United States that offer better climate protection without harming the ozone layer. This is the agency's first action that addresses refrigerants under the Climate Action Plan, which calls on EPA's Significant New Alternatives Policy (SNAP) Program to identify and approve additional climate-friendly chemicals.

Choosing the Right Path: How Air Travel Affects Climate Change
June 26, 2014 10:40 AM - Winfield Winter, ENN

It has been well documented that one negative of air travel — besides the food — is the emission of CO2 from jet engines. But what about contrails? Dr. Emma Irvine, Professor Keith Shine, and Professor Sir Brian Hoskins, at the Department of Meteorology at the University of Reading have linked contrails to global climate change in a study published in IOP Publishing’s journal Environmental Research Letters. According to their report, contrails may have a greater radiative forcing (the capacity for an agent to enact climate change via warming) than CO2.

Solar Power Meets Half of Germany's Energy Demand
June 26, 2014 10:00 AM - Andrew Burger, Triple Pundit

A core facet of Chancellor Merkel's historic "Energiewende" clean energy transition, Germany has led the world in driving adoption of solar energy technology and systems. Although it is now pulling back hard on incentives, the market momentum created by its precedent-setting solar energy feed-in tariff (FiT) persists.

Getting a better handle on CO2, NASA will help!
June 26, 2014 06:17 AM - Roger Greenway, ENN

From all the news about how anthropogenic emissions of CO2 are increasing tremendously (remember the hockey stick graph?) you would think that these emissions are causing all the atmospheric increases of CO2. And, our use of fossil fuels is increasing exponentially, with more than half of all fossil fuels ever used by humans being consumed in the last 20 years. However, in comparison with the amount of carbon that enters the atmosphere from natural sources, our fossil fuel emissions are modest. "Carbon dioxide generated by human activities amounts to only a few percent of the total yearly atmospheric uptake or loss of carbon dioxide from plant life and geochemical processes on land and in the ocean," said Gregg Marland, a professor in the Geology Department of Appalachian State University, Boone, North Carolina. "This may not seem like much, but humans have essentially tipped the balance."
