Many people are familiar with the haunting images of wildlife — including sea turtles, dolphins and seals — tangled in abandoned fishing nets.

For more than a century, American cities have been sliced and diced by high-traffic roadways.

Reducing pollution from aerosol particles would improve air quality. It could also increase the amount of sunlight accessible to plants—enhancing their ability to remove carbon dioxide from the atmosphere and mitigate climate change.

Hair products often contain ingredients that easily evaporate, so users may inhale some of these chemicals, potentially posing health repercussions. 

Exposure to fine particulate air pollutants from coal-fired power plants (coal PM2.5) is associated with a risk of mortality more than double that of exposure to PM2.5 from other sources, according to a new study led by George Mason University, The University of Texas at Austin, and Harvard T.H. Chan School of Public Health. 

Shahan Salim, a PhD candidate in the School of Public Health Sciences and a member of the Waterloo Climate Institute’s COP 28 delegation, has designed, in partnership with UNICEF in Mongolia, a platform to use data from low-cost air quality sensors to monitor and predict adverse outcomes related to air pollution exposure in underserved communities.

Since launching 16 months ago, the EMIT imaging spectrometer aboard the International Space Station has shown an ability to detect more than just surface minerals.

We are all too aware of the global plastic problem. Plastics are unsustainably produced, made, and disposed of, with the material found in the ocean, in landfills, on beaches, and even in the Antarctic.

The Hunga Tonga-Hunga Ha’apai volcano changed the chemistry, dynamics of Earth’s stratosphere.

Carbon dioxide removal (CDR) technologies that could be critical tools to combat climate change have developed in line with other technologies from the last century.
