In Case You Missed It

Will switching to electric vehicles contribute to significant reductions in particulate matter?

A recent study showed that most particulate-matter mass emissions from internal-combustion vehicles comes from brakes, tires, and road dust in countries with regulated emissions from engines. Thus, moving to electric vehicles may only lead to small reductions in particulate-matter mass emissions from the vehicles.


Funding for research on climate geoengineering via aerosols is being debated in US congress.


A large wildfire near Ft. McMurray, Alberta, Canada released a large amount of particles into the atmosphere, impacting large regions of North America. Here is a collection of images from space showing the magnitude of the smoke.


Aerosol physics underlies research on the spread of airbornecommunicable diseases.
