A new Southwest Research Institute study tackles one of the greatest mysteries about Titan, one of Saturn's moons: the origin of its thick, nitrogen-rich atmosphere. The study posits that one key to Titan's mysterious atmosphere is the 'cooking' of organic material in the moon's interior.
Scientists predict that certain regions of the United States will experience higher levels of pollutants that cause smog, acid rain and respiratory problems due changes in forest soils from climate change.
Future generations could be faced with an environmental 'time bomb' if climate change is to have a significant effect on the world's essential groundwater reserves.
U of T Engineering researchers have examined dust from homes in Fort McMurray, Alta., for evidence of harmful toxins left in the aftermath of the devastating 2016 wildfire. Their study reveals normal levels of contaminants that are comparable to homes across Canada, and so far, no evidence of long-term health risks from fire-ash exposure in residents' homes.
A new study, "Mission-Driven Research for Stratospheric Aerosol Geoengineering," published in Proceedings of the National Academy of Sciences, sets out to establish a roadmap for responsible exploration of geoengineering.
Urban planners should plant hedges, or a combination of trees with hedges -- rather than just relying on roadside trees -- if they are to most effectively reduce pollution exposure from cars in near-road environments, finds a new study from the University of Surrey.
Researchers at MIT have analyzed dust deposited off the coast of west Africa over the last 240,000 years, and found that the Sahara, and North Africa in general, has swung between wet and dry climates every 20,000 years.
In China, the rapid reduction of the pollutant PM 2.5 dramatically altered the chemistry of the atmosphere, leading to an increase in harmful ground-level ozone pollution, especially in large cities.
As human activities cause the Earth's temperature to increase, reliable, well-studied weather patterns like the Madden-Julian Oscillation will change too, say researchers at Colorado State University.
Tropical Cyclone Cilida appeared as a large and powerful hurricane on imagery from NASA-NOAA's Suomi NPP satellite on Dec. 21. Cilida is located north of the island of Mauritius in the Southern Indian Ocean.
