Fracking Footprint Seen From Space
October 10, 2014 08:38 AM - ClickGreen Staff, ClickGreen

An unexpectedly high amount of the climate-changing gas methane, the main component of natural gas, is escaping from the Four Corners region in the US Southwest, according to a new study by the University of Michigan and NASA. The researchers mapped satellite data to uncover the nation's largest methane signal seen from space. They measured levels of the gas emitted from all sources, and found more than half a teragram per year coming from the area where Arizona, New Mexico, Colorado and Utah meet. That's about as much methane as the entire coal, oil, and gas industries of the United Kingdom give off each year.

Poland will buy in to climate change plan IF it gets aid
October 10, 2014 06:27 AM - EurActiv

Poland says it will need cash and help in curbing its emissions if it is to sign up for a new decade of EU green energy policy at talks this month, according to a document seen by Reuters. The document shows the 28 EU member states are broadly ready to agree a new set of 2030 goals to follow on from 2020 energy and environment policy, although Europe's biggest power Germany says it will not agree a deal "at any price".

Sea Turtles in Hawaii getting tumors and we are the cause
October 7, 2014 08:09 AM - University of Hawai'i at Mānoa

Hawai'i's sea turtles are afflicted with chronic and often lethal tumors caused by consuming non-native algae, "superweeds," along coastlines where nutrient pollution is unchecked. The disease that causes these tumors is considered the leading cause of death in endangered green sea turtles. The new research was just published in the scientific journal PeerJ. Turtles that graze on blooms of invasive seaweeds end up with a diet that is rich in a particular amino acid, arginine, which promotes the virus that creates the tumors. Scientists at the University of Hawai'i at Mānoa and their NOAA colleague estimate that adult turtles foraging at high-nutrient grazing sites increase their arginine intake 17—26 g daily, up to 14 times the background level.

Does the public trust what scientists say?
October 6, 2014 03:58 PM - Princeton University

If scientists want the public to trust their research suggestions, they may want to appear a bit "warmer," according to a new review published by Princeton University's Woodrow Wilson School of Public and International Affairs. The review, published in the Proceedings of the National Academy of Sciences (PNAS), shows that while Americans view scientists as competent, they are not entirely trusted. This may be because they are not perceived to be friendly or warm.

How Air Pollution Affects River-Flow

Air pollution has had a significant impact on the amount of water flowing through many rivers in the northern hemisphere, according to the results of a new study. The paper shows how pollution, known as aerosols, can have an impact on the natural environment and highlights the importance of considering these factors in assessments of future climate change.

Dog waste contaminates our waterways
October 1, 2014 10:50 AM - American Chemical Society

Americans love their dogs, but they don't always love to pick up after them. And that's a problem. Dog feces left on the ground wash into waterways, sometimes carrying bacteria — including antibiotic-resistant strains — that can make people sick. Now scientists have developed a new genetic test to figure out how much dogs are contributing to this health concern, according to a report in the ACS journal Environmental Science & Technology.

Chinese Now Emit More Carbon Per Capita Than Europeans
September 24, 2014 09:39 AM - Jeremy Hance, MONGABAY.COM

Last year, the people of China emitted more carbon per person than those in the EU, according this year's Global Carbon Budget. The report, updated annually, also found that global emissions jumped 2.5 percent last year and are set to hit a record high of 40 billion tonnes this year. The findings highlight how little global society has done to stem emissions, despite numerous pledges and past global agreements.

Action to limit CO2 emissions IS needed now!
September 22, 2014 07:47 AM - ScienceDaily

Carbon dioxide emissions continue to track the high end of emission scenarios, eroding the chances to keep global warming below 2°C, and placing increased pressure on world leaders ahead of the United Nations Climate Summit on the 23rd September. Global carbon dioxide emissions from fossil fuel combustion and cement production grew 2.3 per cent to a record high of 36.1 billion tonnes CO2 in 2013. In 2014 emissions are set to increase a further 2.5%, 65 per cent above the level of 1990.

Electric vehicles getting even "Greener"
September 16, 2014 03:01 PM - Union of Concerned Scientists

Sixty percent of Americans now live in regions where electric vehicles (EVs) produce fewer heat-trapping global warming emissions per mile than the most efficient hybrids, according to an updated analysis from the Union of Concerned Scientists (UCS). In 2012, that number was just 45 percent. "Electric vehicles are doing more and more to fulfill their technological promise," said Don Anair, research director for UCS's Clean Vehicles Program. "If we want to reduce transportation pollution and oil use, a big part of the answer is to be like Bob Dylan and go electric."

Air pollution found harmful to young brains
September 15, 2014 04:19 PM - University of Montana via EurekAlert

Findings by University of Montana Professor Dr. Lilian Calderón-Garcidueñas, MA, MD, Ph.D., and her team of researchers reveal that children living in megacities are at increased risk for brain inflammation and neurodegenerative changes, including Alzheimer’s or Parkinson’s disease. Calderón-Garcidueñas’ findings are detailed in a paper titled "Air pollution and children: Neural and tight junction antibodies and combustion metals, the role of barrier breakdown and brain immunity in neurodegeneration."
