How to Help Californians Affected by the North Bay Wildfires
October 10, 2017 04:21 PM - S.E. SMITH

Fast-moving wildfires are devastating parts of Northern California, including Sonoma and Napa Counties, just north of the Bay Area. Victims — and their animals — displaced by evacuation orders and property loss need your help.

When Shipping Petroleum, Air Pollution and Greenhouse Gas Emissions Costs More Than Accidents
October 10, 2017 03:18 PM - Carnegie Mellon University

While the policy debate surrounding crude oil transportation costs has emphasized accidents and spills, a new study by Carnegie Mellon University and University of Pittsburgh researchers indicates the debate is overlooking a far more serious external cost—air pollution and greenhouse gas emissions. 

Formation of coal almost turned our planet into a snowball
October 10, 2017 02:44 PM - Potsdam Institute for Climate Impact Research (PIK)

While burning coal today causes Earth to overheat, about 300 million years ago the formation of that same coal brought our planet close to global glaciation. For the first time, scientists show the massive effect in a study published in the renowned Proceedings of the US Academy of Sciences. When trees in vast forests died during a time called the Carboniferous and the Permian, the carbon dioxide (CO2) they took up from the atmosphere while growing got buried; the plants’ debris over time formed most of the coal that today is used as fossil fuel. Consequently, the CO2 concentration in the atmosphere sank drastically and Earth cooled down to a degree it narrowly escaped what scientists call a ‘snowball state’.

UBC researchers take the 'stink' out of wastewater treatment
October 10, 2017 01:31 PM - University of British Columbia Okanagan Campus

A foul smell and safety concerns can leave many residents turning their nose at the idea of a wastewater treatment plant in their neighbourhood.

But researchers from UBC’s Okanagan campus have developed a new way of making wastewater treatment dramatically safer and better smelling by using common and inexpensive chemicals.

Little growth observed in India's methane emissions
October 10, 2017 01:19 PM - University of Bristol

Methane is the second most powerful greenhouse gas and concentrations are rising in the atmosphere. Because of its potency and quick decay in the atmosphere, countries have recognised that reduction of methane emissions are a means toward mitigating global warming.

Clear Lakes Disguise Impaired Water Quality
October 10, 2017 11:52 AM - University of Minnesota

Looks can be deceiving.

Look at a hundred lakes in the agricultural heartland of the United States and you will likely see green lakes surrounded by green fields. The nitrogen and phosphorus in agricultural fertilizers that help crops grow also fuel the growth of algae and cyanobacteria that in excess can turn lakes the color of pea soup.

University of Leicester scientists investigate link between air pollution and type 2 diabetes
October 10, 2017 11:44 AM - University of Leicester

An interdisciplinary team of scientists from the Universities of Leicester and other institutions has played a pivotal role in research investigating a possible link between air pollution and the rise in type 2 diabetes.

New research, published in the journal Environment International, examined data from 10,443 participants from diabetes screening studies in Leicestershire, UK.

The exposure to air pollution, the number of cases of type 2 diabetes and the impact of demographic and lifestyle factors were all considered.

Activated Carbon Could Stop Dioxin Health Risk
October 10, 2017 08:23 AM - Michigan State University

New research from Michigan State University has shown for the first time that activated carbon – a substance widely used in water purification – can help eliminate the health risks associated with soils, sediments and surface water polluted by highly toxic dioxins.

Stephen Boyd, a University Distinguished Professor in the MSU Department of Plant, Soil and Microbial Sciences, led the study, which is published online in the journal Environmental Toxicology and Chemistry. The research looked specifically at soil and freshwater ecosystems that had been contaminated mainly through the industrial manufacture of pesticides and other chemicals.

Ammonia Emissions Unlikely To Be Causing Extreme China Haze
October 6, 2017 11:20 AM - Georgia Institute of Technology

As China struggles to find ways to remedy the noxious haze that lingers over Beijing and other cities in the winter, researchers from Georgia Institute of Technology have cast serious doubt on one proposed cause: high levels of ammonia in the air.

The wintertime air pollution has gained attention in the scientific community in recent years, prompting some scientists to propose that ammonia, emitted into the air from agricultural activities and automobiles, could be a precursor that strongly promotes the formation of the haze.

Georgia Tech researchers countered that theory in a study published September 21 in the journal Scientific Reports. The study was sponsored by the National Science Foundation.
