The mystery of the disappearing plastic trash in the oceans solved!
December 27, 2014 08:49 AM - Lizabeth Paulat, Care2
Many of us have seen the photos of plastic refuse in the ocean, the large islands of bags and waste that collect at tidal crossroads. Yet when scientists took a survey of the ocean earlier this year, they found a suspicious amount had disappeared. Was it just our good luck that pollution was decreasing? Hardly. It had simply been sinking, breaking apart and embedding itself in the sediment.
Fibers of microplastic, which are similar in diameter to a human hair, have sunk into deep water reserves across the world. For every bag floating across the ocean’s surface, there’s much more of the stuff laying in the ocean floor underneath. How much plastic is there? Well, according to the research, it’s so widespread that they’ve estimated microplastic is on every kilometer of the sea floor across the globe.
NASA maps CO2 emissions over the entire planet
December 25, 2014 11:39 AM - BRIAN KAHN, CLIMATE CENTRAL, via DiscoveryNews
It’s been a busy five months for NASA’s newest carbon dioxide-monitoring satellite, snapping up to 1 million measurements a day of how carbon dioxide moves across the planet. Now NASA scientists have shared the first global maps created using that data, showing one of the most detailed views of CO2 ever created.
The satellite — known as OCO-2 — has been in orbit since July. While it’s returned some preliminary data, NASA showed off its global reach for the first time on Thursday at the annual American Geophysical Union meeting.
Carbon Dioxide Threat To Mussels' Shells
December 24, 2014 01:09 PM - The Ecologist, The Ecologist
The world's mussel population could be under threat as rising CO2 levels in atmosphere and oceans makes their shells weaker and more brittle shells - making them more vulnerable to stormy seas, and predation.
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.
