Obama Rejects Keystone XL Pipeline
November 9, 2015 06:41 AM - Center for Biological Diversity
In a crucial victory for the climate, wildlife and the millions who spoke against it, President Obama rejected the Keystone XL project today, saying that building the tar sands oil pipeline is not in the national interest.
Over the past four years, scientists, environmentalists, tribes, farmers, celebrities and business people joined forces to fight the pipeline, with more than 2 million comments submitted to the U.S. State Department, tens of thousands participating in rallies against Keystone in all 50 states, and thousands of citizens arrested in peaceful civil disobedience.
“This is a historic moment, not just for what it means about avoiding the impacts of this disastrous pipeline but for all of those who spoke out for a healthy, livable climate and energy policies that put people and wildlife ahead of pollution and profits,” said Valerie Love with the Center for Biological Diversity. “President Obama did the right thing, but he didn’t do it alone: Millions of Americans made their voices heard on this issue, and will continue pressing Obama and other political leaders to do what’s necessary to avoid climate catastrophe.”
Invasive marine species benefit from rising CO2 levels
November 9, 2015 06:24 AM - Plymouth University
Ocean acidification may well be helping invasive species of algae, jellyfish, crabs and shellfish to move to new areas of the planet with damaging consequences, according to the findings of a new report. Slimy, jelly-like creatures are far more tolerant of rising carbon dioxide levels than those with hard parts like corals, since exposed shells and skeletons simply dissolve away as CO2 levels rise. The study, conducted by marine scientists at Plymouth University, has found that a number of notorious ‘nuisance’ species – such as Japanese kelp (Undaria pinnatifida) and stinging jellyfish (Pelagia noctiluca) are resilient to rising CO2 levels.
Acid rain's effects on forest soils found to be reversing
November 8, 2015 08:47 AM - USGS Newsroom
Soil acidification from acid rain that is harmful to plant and aquatic life has now begun to reverse in forests of the northeastern United States and eastern Canada, according to an American-Canadian collaboration of five institutions led by the U.S. Geological Survey.
The new research shows that these changes are strongly linked to acid rain decreases, although some results differ from expected responses.
"Reduced acid rain levels resulting from American and Canadian air-pollution control measures have begun to reverse soil acidification across this broad region," said Gregory Lawrence, a USGS soil and water chemist and lead author. "Prior to this study, published research on soils indicated that soil acidification was worsening in most areas despite several decades of declining acid rain. However, those studies relied on data that only extended up to 2004, whereas the data in this study extended up to 2014. "
The massive Indonesian fires
November 7, 2015 07:25 AM - lisa palmer, Yale Environment360
The fires that blazed in Indonesia’s rainforests in 1982 and 1983 came as a shock. The logging industry had embarked on a decades-long pillaging of the country’s woodlands, opening up the canopy and drying out the carbon-rich peat soils. Preceded by an unusually long El Niño-related dry season, the forest fires lasted for months, sending vast clouds of smoke across Southeast Asia.
Fifteen years later, in 1997 and 1998, a record El Niño year coincided with continued massive land-use changes in Indonesia, including the wholesale draining of peatlands to plant oil palm and wood pulp plantations. Large areas of Borneo and Sumatra burned, and again Southeast Asians choked on Indonesian smoke.
Turns out, licking a wound DOES make it heal faster!
November 6, 2015 03:31 PM - LUND UNIVERSITY via EurekAlert
By licking a wound it heals faster -- this is not simply popular belief, but scientifically proven. Our saliva consists of water and mucus, among other things, and the mucus plays an important role. It stimulates white blood cells to build a good defense against invaders, according to a group of researchers at Lund University in Sweden together with colleagues from Copenhagen and Odense in Denmark.
"White blood cells are among other places located in the oral mucosa, and they represent the body's first line of defence against infectious agents. The mucus in the mouth causes the white blood cells to throw out a 'net' that traps bacteria", explains Ole Sørensen from the Division of Infection Medicine.
The new imperative in buildings, cleaner air!
November 6, 2015 06:59 AM - Bill Roth, Triple Pundit
A study just published by the Harvard T.H. Chan School of Public Health has linked a building’s indoor air quality directly to its occupants’ cognitive function. Cognitive function is defined as the cerebral activities that lead to knowledge including acquiring information, reasoning, attention, memory and language.
The revolutionary finding of this study is that lowering indoor air levels of carbon dioxide and volatile organic compounds (VOCs) improves human cognitive function. In other words: Cleaner air makes us smarter!
Rat poisons endanger California wildlife
November 5, 2015 08:13 AM - Center for Biological Diversity
Researchers at the University of California released a study today indicating that rat poisons increasingly pose a significant risk for California’s imperiled Pacific fishers, small, forest-dwelling mammals that are protected under the California Endangered Species Act. The study shows that increasing numbers of fishers are being exposed to, and dying from, greater varieties of rat poisons, or rodenticides, found at illegal marijuana farms. It also affirms reports and data from across the state that rodenticides continue to poison and kill numerous California wildlife species.
“These poisons are silently killing our country’s most majestic wildlife by indiscriminately causing animals to literally bleed to death from the inside out,” said Jonathan Evans, environmental health legal director at the Center for Biological Diversity. “It’s time to ban these poisons from the market to protect fishers, bald eagles, great horned owls and kit foxes from a painful, gruesome fate.”
Do you get the Winter blah's? Light therapy might not be the best treatment.
November 5, 2015 08:02 AM - UNIVERSITY OF VERMONT via EurekAlert
A new study to be published online November 5 in the American Journal of Psychiatry casts a shadow on light therapy's status as the gold standard for treating SAD, or seasonal affective disorder.
While the treatment was effective at addressing acute episodes of SAD, a SAD-tailored version of cognitive-behavioral therapy (CBT) was significantly better at preventing relapse in future winters, the study found. Led by University of Vermont psychology professor Kelly Rohan, the research initiative, funded by a $2 million grant from the National Institute of Mental Health, is the first large scale study to examine light therapy's effectiveness over time.
More bad news for VW: CO2, gas engines involved
November 4, 2015 09:09 AM - EurActiv
Germany's Volkswagen said Tuesday (3 November) an internal probe had found that 800,000 more vehicles showed "inconsistencies" on carbon dioxide emissions, including the first petrol engines.
Among the engines affected are 1.4, 1.6 and 2.0 litre motors of VW, Skoda, Audi and Seat vehicles, said a VW spokesman, adding that these cars had been found to be releasing more of greenhouse gas CO2 than previous tests had shown.
At least one petrol engine is concerned, the company said.
West Antarctica snow accumulation increased in the 20th century
November 4, 2015 06:37 AM - Dr Liz Thomas lead author, British Antarctic Survey
Annual snow accumulation on West Antarctica’s coastal ice sheet increased dramatically during the 20th century, according to a new study published today (Wednesday 4 November) in the American Geophysical Union journal Geophysical Research Letters. The last three decades saw more snow build up on the ice sheet than at any other time in the last 300 years.
The research gives scientists new insight into Antarctica’s ice sheet. Understanding how the ice sheet grows and shrinks over time enhances scientists’ understanding of the processes that impact global sea levels.
The new study used ice cores to estimate annual snow accumulation from 1712 to 2010 along the coastal West Antarctic. Until 1899, annual snow accumulation remained steady, averaging 33 and 40 centimeters (13 and 16 inches) water, or melted snow, each year at two locations.
