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
October 6, 2014 10:13 AM - ClickGreen Staff, ClickGreen
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."
Most Polluted Countries
September 15, 2014 07:38 AM - Lizabeth Paulat, Care2
The WHO has released a new study ranking countries with the worst air pollution. When we consider air pollution most of us will automatically think of China. However, it was nowhere to be found in the top 10 offenders. This, by the way, is not because they’ve suddenly cleaned up their act, but rather because this study ranked countries as a whole, rather than cities. So here are the top 5 countries with the worst air pollution, and what they are trying to do to combat it. 1. Pakistan Pakistan made #1 on the list with a PM 2.5 pollution level of 101 ug/m3. Now, that might not make sense so let me break it down: PM 2.5 stands for the size of the particles of pollution. The size (2.5) is frequently cited as the most detrimental because it can travel deep into lungs and cause a variety of ailments. Good examples of these particles are smoke, mold and dust. The ug/m3 part stands for micrograms per unit meter of air. So Pakistan has 101 micrograms of PM 2.5 pollutants per unit meter of air.
Help for Bluefin Tuna!
September 11, 2014 07:13 AM - Dennis Normile Science
A multinational organization that coordinates fishing activities in the western Pacific is throwing a lifeline to heavily overfished Pacific bluefin tuna stocks. Speaking today at a press briefing, Japanese officials provided details on a plan agreed to last week that aims to rebuild the spawning population by halving the catch of juveniles and limiting takes of mature fish as well. The proposal calls for total Pacific bluefin catches to be kept below the 2002 to 2004 annual average levels and for catches of fish weighing fewer than 30 kilograms—juveniles too young to spawn—to be reduced to 50% of those levels.
Hazardous waste-eating bacteria discovered
September 10, 2014 09:07 AM - The University of Manchester
Although bacteria with waste-eating properties have been discovered in relatively pristine soils before, new research shows for the first time that microbes that can survive in the very harsh conditions expected in radioactive waste disposal sites have also been found. The ultimate aim of this research conducted by the University of Manchester is to improve our understanding of the safe disposal of radioactive waste underground by studying the unusual diet of these hazardous waste eating microbes.
