Greenland ice sheet holds North Americas environmental history clues despite distance.

Reno NV (SPX) Jan 12, 2024 - Human activity, from burning fossil fuels and fireplaces to the contaminated dust produced by mining, alters Earths atmosphere in countless ways. Records of these impacts over time are preserved in

New study: Microplastic fibers are settling substantially slower than spherical particles in the atmosphere and might even reach stratosphere How far

The study, titled "Atmospheric Transport is a Major Pathway of Microplastics to Remote Regions," was published in Nature Communications in July 2020. The study used two methods to estimate the amounts of fine particles emitted by tyres & brakes, as well as well-established atmospheric circulation models to assess how the particles are blown around the world.

Several years ago, while analyzing ice core samples from Antarctica’s James Ross Island, scientists Joe McConnell, Ph.D., and Nathan Chellman, Ph.D

Humans have impacted Earths atmosphere for more than 700 years, far longer than the Industrial Revolution and much longer than initially believed, according to a new study.

While waste disposed of in nature remains at the same place, air pollution does not stop at national borders. The wind can carry exhaust fumes or...

The research findings were published on Monday, April 12, in the Proceedings of the National Academy of Science. The researchers examined airborne microplastics, which have been far less studied than plastic in oceans and rivers. Researchers said human pollution has led to a global plastic cycle similar to natural processes such as the carbon cycle with plastic moving through the atmosphere, oceans and land. The result is the “plastification” of the planet, said one scientist. Lead author ...

Published Monday, April 12, in the journal  Proceedings of the National Academy of Sciences, the study also found that sea spray and agricultural runoff generated 10 and five percent of atmospheric microplastics, respectively. Meanwhile, in hotspots for microplastic sources and accumulation, microplastics lingered in the air for up to 6.5 days. Lead author Janice Brahney, an assistant professor from the department of watershed sciences at Utah State University, said she and her colleagues ...
