Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Pollution from ships creates lines of clouds that can stretch hundreds of miles. The difference helps explain how much industrial pollution influences clouds. NASA Earth Observatory.

New method for the precise analysis of the composition of secondary organic aerosols in PM

Green Car Congress

Atmospheric aerosols are a major pollutant of the Earth’s atmosphere. Consequently, SOA particles are complex mixtures of organic and inorganic compounds that have a negative impact on human health, influence the biosphere and take part in climate change. They consist of fine particulate matter with diameters below 100 ?m

Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

It also assesses the strengths and weaknesses of EVs and CNGVs from a perspective of climate change and environmental impact. Although EVs have a greater GHG reduction benefit than CNGVs, they may increase life-cycle emissions of criteria pollutants, simply because coal is heavily involved.

NASA GISS Study Finds That Methane Has an Elevated Warming Effect Due to Interactions With Aerosols

Green Car Congress

As a result of their findings, published in the 30 October issue of the journal Science , the authors argue that assessments of multigas mitigation policies, as well as any separate efforts to mitigate warming from short-lived pollutants, should include gas-aerosol interactions.
