In a cohort study of a subset of 2050 newborns from the Children’s Health Study in southern California, researchers at the University of Southern California (USC) found that an increase of 2 standard deviations in prenatal exposure to particulate matter in air pollution was associated with higher newborn total thyroxine (TT4) measures.

EPA Climate Change Adaptation Plan sees likely increase in tropospheric ozone, with more difficulty in attaining NAAQS in many areas

FEBRUARY 10, 2013

Among the many climate-related vulnerabilities that can impact its mission, the US Environmental Protection Agency (EPA) cites a likely increase in tropospheric ozone pollution as potentially making it more difficult to attain National Ambient Air Quality Standards ( NAAQS ) in many areas with existing ozone problems.

The California Air Resources Board (ARB) and the National Oceanic and Atmospheric Administration (NOAA) are collaborating in the $20-million CalNex research project to examine the nexus between air pollution and climate change. The complex roles that ozone and aerosols play in the atmosphere provide examples of such trade-offs.

Study: 25% EV adoption would save US $17B annually from avoided climate change & pollution damages

Green Car Congress

AUGUST 18, 2020

A new study led by researchers from Northwestern University projects that if electric vehicles replaced 25% of combustion engine cars currently on the road, the United States would save approximately $17 billion annually by avoiding damages from climate change and air pollution. The open-access paper is published in AGU’s journal GeoHealth.

The study focuses on the period between 2005 and 2018 and tracks combustion emissions of various polluting compounds from various sectors, looking at every state in the contiguous United States, from season to season and year to year. Scientists have long known that pollution observes no boundaries, one of the prime examples being acid rain.

Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. Ozone, a key component of smog and also a greenhouse gas, damages crops and human health. Tropospheric ozone and black carbon (BC) contribute to degraded air quality and global warming.
