Warming Seas Double Snowfall Around North America's Tallest Peaks

Snowfall on a major summit in North America’s highest mountain range has more than doubled since the beginning of the Industrial Age, according to a study from Dartmouth College, the University of Maine, and the University of New Hampshire.

Polluted woods: leaves contaminate soil with hydrocarbon

In the Autumn leaves fall and apparently contaminate soil. It happens in the Italian woods where remediation is required by law for heavy hydrocarbon concentration greater than 50 milligrams per kilo.

Healthier Air due to the Low Emission Zone

The Low Emission Zone in Leipzig was established in March 2011, allowing only access of Diesel vehicles of Euro4 and higher with few exceptions. The ban of older vehicles and subsequent modernization of the car fleet resulted in slightly reduced PM10 and PM2.5 mass concentrations. However, the mass concentration of black carbon (soot particles) emitted mainly from Diesel vehicles decreased by 60% at the street site. These particles are believed to be most dangerous due to their carcinogenic trace compounds such as polycyclic aromatic hydrocarbons. Furthermore, also the number concentration of ultrafine particles, which can penetrate deep into the lungs, decreased by approximately 70%. Despite modernized Diesel vehicles, nitrogen oxides concentrations did not follow these trends and remained nearly constant. The main achievement of the Low Emission Zone was the improvement of air quality by the reduction of the most dangerous particles.

Siting Solar, Sparing Prime Agricultural Lands

Unconventional spaces could be put to use generating renewable energy while sparing lands that could be better used to grow food, sequester carbon and protect wildlife and watersheds, says a study led by the University of California, Davis.

Remote imaging advances medical diagnoses

University of Saskatchewan researcher Scott Adams has proven that MELODY telerobotic sonography, a French-developed system that allows doctors to do long distance ultrasound imaging, is feasible for abdominal and prenatal imaging. Adams is part of the first research team to test this technology in North America.

“The new telerobotic system could help save time and money. Patients may get earlier diagnoses while reducing the strain on major referral hospitals,” said U of S medical imaging professor Paul Babyn, Adams’s supervisor along with surgery professor Ivar Mendez. 

Globe had 3rd warmest year to date and 5th warmest November on record

With a warm start to the year and only one month remaining, the globe remains on track to go down as the third warmest year in the 138-year climate record.   

So, let's get straight to the data and dive deeper into NOAA’s monthly analysis to see how the planet fared for November, the season and the year to date:

Probing Air Pollution with Laser Sensors

Mark Zondlo, an associate professor of civil and environmental engineering at Princeton University and its Andlinger Center for Energy and the Environment, develops tools to measure air pollution in more sophisticated and nimble ways than previously possible.

His specially engineered laser sensors and drones help reveal the impact of greenhouse gases and air pollutants on the climate, where pollutants come from, and how clouds of air pollution — such as smog — form. The ultimate goal is to inform policy that will clear the air and our lungs and slash air pollution’s staggering impact on human mortality. Severe air pollution causes the premature death worldwide of more than 5.5 million people per year, according to news reports based on data compiled for the Global Burden of Disease project.

ASU scientists discover gut bacteria in bees spread antibiotic-resistant genes to each other

It’s the kind of thing you might lose sleep over.

How will humans survive serious infections in the future if we’re running out of tools today to fight them? Antibiotic resistance among disease-causing bacteria is of global concern, as some last-resort drugs can no longer cure common illnesses such as urinary tract infections. 

Air pollution project harnesses the power of backyard science

Right now, a handful of motivated Fort Collins citizens are doing something a little out of the ordinary. They’re collecting cutting-edge scientific data from their backyards that may soon help NASA create maps of global air pollution.

Heat from below Pacific Ocean fuels Yellowstone, study finds

Recent stories in the national media are magnifying fears of a catastrophic eruption of the Yellowstone volcanic area, but scientists remain uncertain about the likelihood of such an event. To better understand the region’s subsurface geology, University of Illinois geologists have rewound and played back a portion of its geologic history, finding that Yellowstone volcanism is far more complex and dynamic than previously thought.
