Road salt not good for streams
December 29, 2014 08:10 AM - Cheryl Corley, NPR
This is the time of year when it's not uncommon to see big trucks barreling down highways and streets spreading road salt.
Steve Corsi, a hydrologist with the U.S. Geological Survey, says that translates into high levels of chloride concentrations for rivers like the Milwaukee in Wisconsin or 18 other streams near urban areas in Illinois, Ohio, Colorado and several other states.
"At many of the streams, concentrations have now exceeded those that are harmful to aquatic life," he says.
East Cost "nuisance" flooding already increasing
December 28, 2014 08:48 AM - ecoRI news staff
By 2050, much of U.S. coastal areas are likely to be threatened by 30 or more days of flooding annually because of dramatically accelerating impacts from sea-level rise, according to a new National Oceanic and Atmospheric Administration (NOAA) study.
The findings appear in a paper entitled “From the Extreme to the Mean: Acceleration and Tipping Points for Coastal Inundation due to Sea Level Rise” and follows an earlier study by the report’s co-author, William Sweet, Ph.D., a NOAAA oceanographer.
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.
Christmas gift for Gray Wolves in three states
December 26, 2014 08:32 AM - Alicia Graef, Care2
Christmas came early this year for gray wolves thanks to an awesome ruling handed down by a federal judge that immediately reinstated federal protection for them in the Great Lakes region.
The ruling affects wolves in Michigan, Minnesota and Wisconsin, and, unless overturned, will stop these three states from holding any more hunting and trapping seasons, which is expected to protect an estimated 3,700 wolves.
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.
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.
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.”
WWF: Climate Change talks disappointing
December 14, 2014 10:02 AM - WWF
The WWF issued the following statement from Samantha Smith, Leader of WWF’s Global Climate and Energy Initiative at the close of the UN climate talks in Lima, Peru:
“Against the backdrop of extreme weather in the Philippines and potentially the hottest year ever recorded, governments at the UN climate talks in Lima opted for a half-baked plan to cut emissions.
“Governments crucially failed to agree on specific plans to cut emissions before 2020 that would have laid the groundwork for ending the fossil fuel era and accelerated the move toward renewable energy and increased energy efficiency.
New EU-wide food labeling rules apply this weekend
December 12, 2014 01:31 PM - EurActiv
New EU food labelling rules will come into force on Saturday (13 December). The aim is to ensure that consumers receive clearer and more accurate information about what they buy and eat. The new rules will force restaurants and cafés to list 14 different allergens in the menus - including nuts, gluten, lactose, soy or milk. Displaying allergens was until then only mandatory for pre-packed foods. Nano components will also have to be included in the ingredients list. Oils will need to refer to the plants used in their production, such as sunflower, palm or olive. Fresh meat from pigs, sheep, goats and poultry will need to carry a mandatory origin label, with a font size of at least 1.2 milimetres.
