New study analyzes sound sensitivity of marine invertebrates
December 22, 2014 02:57 PM - Woods Hole Oceanographic Institution
Noise pollution in the ocean is increasingly recognized as harmful to marine mammals, affecting their ability to communicate, find mates, and hunt for food. But what impact does noise have on invertebrates -- a critical segment of the food web? Very few studies have attempted to answer that question. The harder question to answer might be 'How do you measure hearing in ocean invertebrates'? A new study by researchers at Woods Hole Oceanographic Institution and their colleagues examined behavioral responses to sound by cuttlefish, a type of shell-less mollusk related to squid and octopi. The study is the first to identify the acoustic range and minimum sound sensitivity in these animals. Their findings, published in the Journal of Experimental Biology, can help decision makers and environmental managers better understand the impacts of noise in the ocean.
Diesel truck air pollution better thanks to California regulations
December 21, 2014 08:37 AM - Lawrence Berkeley National Laboratory via ScienceDaily.
Ever wonder what's in the black cloud that emits from some semi trucks that you pass on the freeway? Lawrence Berkeley National Laboratory (Berkeley Lab) scientist Thomas Kirchstetter knows very precisely what's in there, having conducted detailed measurements of thousands of heavy-duty trucks over months at a time at two San Francisco Bay Area locations.
With a specially outfitted research van equipped with sophisticated monitors for several pollutant types, he and his team are studying emissions levels from diesel trucks to understand and analyze the impact of new control technologies and California air pollution regulations.
Is Australia on the wrong track on climate change?
December 19, 2014 01:17 PM - Kieran Cooke & Oliver Tickell, The Ecologist
Despite record heat and drought Australia's emissions and coal exports are soaring, says a new report, and both are increasing as a matter of government policy. But a homegrown climate action movement is putting a spanner in the works - and just stopped its first coal train.
Australia's response to climate change is headed completely backwards. If we can stop this new coal mine we set a precedent for the rest of Australia to stand up.
New York State to Ban Fracking Due to Health Risks
December 19, 2014 12:09 PM - Jan Lee, Triple Pundit
This week, New York state joined the growing list of states and communities to ban hydraulic fracturing (fracking) within its boundaries. After years of contentious debate over the safety of fracking, Gov. Andrew M. Cuomo’s announcement Wednesday that he would move to unilaterally ban fracking was not completely unexpected. Still, environmental groups are counting the Department of Health’s report that “[high volume hydraulic fracturing] should not proceed in NYS” as a victory.
The role of taxes (and EV's) in reducing CO2 emissions from cars in Europe analyzed
December 19, 2014 08:43 AM - EurActiv
The Netherlands had the lowest CO2 emissions from new cars in the European Union last year, thanks to its tax regime favouring fuel economy and low-carbon vehicles.
Germany and Poland are among the countries with the highest C02 emissions from new cars and the weakest national tax policies, a report by NGO Transport & Environment has found.
Cars are responsible for 15% of Europe’s total CO2 emissions and are the single largest source of emissions in the transport sector.
New York fracking ban has broader implications for America
December 18, 2014 06:48 AM - Center for Biological Diversity
After years of public pressure, New York today became the second state to ban hydraulic fracturing because of risks to people and the environment. The announcement from Gov. Andrew Cuomo adds to the pressure on the Obama administration to end fracking across the country, including on America’s public lands.
“New York just took a huge leap forward in protecting its people and wildlife from the dangers of fracking,” said Kassie Siegel of the Center for Biological Diversity. “Now it’s time for other leaders to follow, including President Obama and Gov. Jerry Brown in California.”
16 Major Companies and Agencies Say No to Chemical Flame Retardants
December 17, 2014 02:29 PM - Jan Lee, Triple Pundit
The debate over chemical flame retardantsseems to be heating up. The Center for Environmental Health, which helped encourage a rewrite of California’s regulations regarding safety standards in furniture manufacturing, announced last week that 16 major furniture manufacturers have now sworn off chemical flame retardants.
Fracking-Related Air Pollution Leads to Major Health Threats
December 16, 2014 03:01 PM - Natural Resources Defense Council
A growing body of evidence shows that people both near and far from oil and gas drilling are exposed to fracking-related air pollution that can cause at least five major types of health impacts, according to a new comprehensive analysis of scientific studies to-date by the Natural Resources Defense Council. The health impacts include respiratory problems, birth defects, blood disorders, cancer and nervous system impacts, raising serious concerns for workers and people living closest to wells, as well as entire regions with high volumes of oil and gas activity.
Road Salt Increases Urban Stream Contamination
December 15, 2014 03:54 PM - USGS Newsroom
Average chloride concentrations often exceed toxic levels in many northern United States streams due to the use of salt to deice winter pavement, and the frequency of these occurrences nearly doubled in two decades. Chloride levels increased substantially in 84 percent of urban streams analyzed, according to a U.S. Geological Survey study that began as early as 1960 at some sites and ended as late as 2011. Levels were highest during the winter, but increased during all seasons over time at the northern sites, including near Milwaukee, Wisconsin; Chicago, Illinois; Denver, Colorado; and other metropolitan areas. The report was published today in the journal Science of the Total Environment.
Pollution May Cause Problems for Pollinators
December 11, 2014 10:57 AM - Lisa Marie Potter, MONGABAY.COM
While unpleasant car exhaust makes us wrinkle our noses, such human-made fumes may pose serious problems to insects searching for nectar. Researchers recently revealed that background odors make finding flowers difficult for pollinators. The study, published in Science, measured how hawk moths (Manduca sexta) pick out the sacred datura flower scent (Datura wrightii) amidst all the other smells that waft through the environment. Datura’s brilliant 15-centimeter trumpets leap from dark, heart-shaped leaves, sending smelly signals into the arid sky of the southwestern deserts where they grow.
