Heavy Oils and Petroleum Coke Raising Vanadium Emissions

ENN Pollution - Sat, 12/16/2017 - 01:06
Human emissions of the potentially harmful trace metal vanadium into Earth’s atmosphere have spiked sharply since the start of the 21st century due in large part to industry’s growing use of heavy oils, tar sands, bitumen and petroleum coke for energy, a new Duke University study finds.“Human emissions of vanadium to the atmosphere now exceed those from all natural sources combined -- by a factor of 1.7,” said William H. Schlesinger, James B. Duke Professor Emeritus of Biogeochemistry at Duke’s Nicholas School of the Environment, who led the study.“Less than two decades ago, the ratio of human to natural emissions was 0.59 to 1, or less than half the current level,” Schlesinger said. “Our analysis suggests that much of this rapid rise can be traced to the increased use of unconventional heavy-petroleum fuels.”

How Much Soil Goes Down The Drain – New Data On Soil Lost Due To Water

ENN Climate - Fri, 12/15/2017 - 23:21
According to a new study, almost 36 billion tons of soil is lost every year due to water, and deforestation and other changes in land use make the problem worse. The study also offers ideas on how agriculture can change to become a part of the solution from being part of the problem.

NASA Sees Tropical Storm Kai-Tak Moving Over the Philippines

ENN Climate - Fri, 12/15/2017 - 22:25
NASA's Aqua satellite provided infrared imagery of Tropical Storm Kai-Tak that revealed the western side of storm had moved into the southern and central Philippines. Infrared data revealed very cold cloud top temperatures with the potential for heavy rainfall.

More frequent fires reduce soil carbon and fertility, slowing the regrowth of plants

ENN Climate - Fri, 12/15/2017 - 20:23
Frequent burning over decades reduces the amount of carbon and nitrogen stored in soils of savanna grasslands and broadleaf forests, in part because reduced plant growth means less carbon being drawn out of the atmosphere and stored in plant matter. These findings by a Stanford-led team are important for worldwide understanding of fire impacts on the carbon cycle and for modeling the future of global carbon and climate change.

Exposure to Larger Air Particles Linked to Increased Risk of Asthma in Children

ENN Pollution - Fri, 12/15/2017 - 20:01
Researchers at The Johns Hopkins University report statistical evidence that children exposed to airborne coarse particulate matter — a mix of dust, sand and non-exhaust tailpipe emissions, such as tire rubber — are more likely to develop asthma and need emergency room or hospital treatment for it than unexposed children.

Prescription drugs in treated wastewater are making fish more vulnerable to predators

ENN Pollution - Fri, 12/15/2017 - 18:41
A team of researchers from Environment Canada and Climate Change Canada and McMaster University have found that fish living downstream from a wastewater treatment plant showed changes to their normal behaviour—ones that made them vulnerable to predators—when exposed to elevated levels of antidepressant drugs in the water.The findings, published as a series of three papers in the journal Scientific Reports, point to the ongoing problem of prescription medications, personal care products and other drugs that end up in the watershed and the impact they have on the natural environment.

NASA Researchers Share Perspective on Key Elements of Ozone Layer Recovery

ENN Climate - Fri, 12/15/2017 - 02:15
Each year, ozone-depleting compounds in the upper atmosphere destroy the protective ozone layer, and in particular above Antarctica. The ozone layer acts as Earth's sunscreen by absorbing harmful ultraviolet radiation from incoming sunlight that can cause skin cancer and damage plants, among other harmful effects to life on Earth. While these different compounds each release either reactive chlorine or bromine, the two active ozone-destroying ingredients, during a series of chemical reactions, the molecules have a range of different lifetimes in the atmosphere that can affect their ultimate impact on the ozone layer and its future recovery.

Melting of East Antarctic Ice Sheet Could Cripple Major U.S. Cities

ENN Climate - Thu, 12/14/2017 - 20:48
The world’s largest ice sheet may be less stable than previously thought, posing an even greater threat to Florida’s coastline. The first-ever marine geologic survey of East Antarctica’s Sabrina Coast, published this week in Nature, concludes that some regions of the massive East Antarctic Ice Sheet have been sensitive to climate change for millions of years. Much like the West Antarctic Ice Sheet, this region of the East Antarctic Ice Sheet is grounded below sea level and local glaciers are experiencing ice mass loss due to ocean warming.
