Over the decade since the Deepwater Horizon spill, thousands of scientists have analyzed its impact on the Gulf of Mexico. The spill affected many different parts of the Gulf, from coastal marshes to the deep sea.

At the Center for Integrated Modeling and Analysis of the Gulf Ecosystem, or C-IMAGE at the University of South Florida, marine scientists have been analyzing these effects since 2011. C-IMAGE has received funding from the Gulf of Mexico Research Initiative – a broad, independent research program initially funded by a US$500 million grant from BP, the company held principally responsible for the spill.

The impacts of recent forest fires in California reach well beyond the burned areas. Smoke from the Camp Fire created hazardous air quality conditions in San Francisco, more than 170 miles to the southwest – but it didn’t stop there. Cross-country winds carried it across the United States, creating hazy conditions in locations as far east as Philadelphia.

As an air pollution exposure scientist, I worry about the extreme levels of air pollution that rise from these fires and affect many people across great distances. They can create unhealthy conditions in far-flung locations where residents probably never think about wildfires. But since major wildfires are becoming increasingly common, I believe it is important for all Americans to know some basics about smoke hazards. Continue reading
