Study finds that Choice of Cool Roofing Materials can Potentially Impact Region's Air Pollution
August 8, 2017 01:22 PM - South Coast Air Quality Management District

In a groundbreaking study released today, scientists at the South Coast Air Quality Management District and the University of Southern California have found that widespread installation of certain “cool roof” materials in the region could slightly increase ozone and fine particulate pollution levels.

Every breath you take: Air pollution from idling cars puts kids at risk

Drivers who drop off their kids at school should turn off their engines

We think of schools as safe places for children but an invisible hazard is lurking right outside the front door,  says a new study from the University of Toronto.

Benefits of Advanced Wood-Burning Stoves Greater Than Thought

A recent study from North Carolina State University finds that advanced wood-burning stoves designed for use in the developing world can reduce air pollution more than anticipated, because gaseous emissions from traditional wood stoves form more particulate matter in the atmosphere than researchers previously thought.

U.S. EPA Releasing Smog Rule
August 4, 2017 05:03 PM - Yale Environment 360

Faced with a lawsuit by 15 states, the U.S. Environmental Protection Agency announced this week it would no longer delay the implementation of a rule requiring states to reduce emissions of smog-creating air pollution. 

Crafted by the Obama administration in 2015, the regulation calls for states to begin meeting stricter ozone standards as of October 1, 2017, lowering the air pollution limit from 0.075 parts per million to 0.070 ppm.  Ground-level ozone, or smog, is created when pollutants from cars, power plants, and other common industrial activities react with sunlight.  It can cause respiratory and other health problems.  In June, U.S. EPA head Scott Pruitt announced the agency would delay implementation of the new standards by one year.

Where there's fire, there's smoke — and social media
August 4, 2017 03:03 PM - Colorado State University

When people see smoke on the horizon, what do they do? Besides (hopefully) calling fire authorities, they post to social media, of course.

The fact that people reliably flock to social media to discuss smoke and fire was the inspiration for a new study by Colorado State University atmospheric scientists. Driven to innovate ways to improve the air we breathe, the scientists have shown that social media, Facebook in this case, could prove a powerful tool.

New dust sources resulting from a shrinking Salton Sea have negative ecological and health impacts
August 3, 2017 02:51 PM - University of California - Riverside

Scientists at the University of California, Riverside investigating the composition of particulate matter(PM) and its sources at the Salton Sea have found that this shrinking lake in Southern California is exposing large areas of dry lakebed, called playa, that are acting as new dust sources with the potential to impact human health.

“Playas have a high potential to act as dust sources because playa surfaces often lack vegetation,” said Roya Bahreini, an associate professor of environmental sciences, who led the research project. “Dust emissions from playas increase airborne PM mass, which has been linked to cardiovascular disease, respiratory disease, and mortality.”

Light pollution as a new threat to pollination

Artificial light disrupts nocturnal pollination and leads to a reduced number of fruits produced by the plant.

A clean future
August 3, 2017 08:26 AM - University of Saskatchewan

A Métis student in the University of Saskatchewan School of Public Health, Adams is one of 16 young leaders from across Canada appointed to the Your Energy Future program.

Participants in the year-long program, delivered in partnership by the Public Policy Forum and leadership development fellowship Action Canada, will become change-makers in Canada’s energy agenda.  They develop strategies to prepare Canadian people, communities and governments to successfully transition to a low-carbon, clean energy future.
