For most people, clouds are just an indication of whether it's a "good" or "bad" day. A team of scientists from Pacific Northwest National Laboratory found that certain clouds hold the key to climate behavior prediction. ...
When it comes to air pollution, further development and integration of complementary analytical methods are needed to understand the effect of atmospheric particles, according to scientists at Pacific Northwest National Laboratory ...
Scientists know relatively little about particles released into the air when a vehicle driver brakes, though evidence suggests that those particles may be more harmful to health than particles exiting the tailpipe.
One of the many effects of global warming is sea-level rise due to the melting and retreat of the Earth's ice sheets and glaciers. As the sea level rises, large areas of densely populated coastal land could ultimately become ...
People who live in São Paulo city in Brazil certainly recall an event that occurred on August 19, 2019, when dark clouds covered the sky and day turned into night. The phenomenon was not caused by local pollution or emissions ...
A study published in the Proceedings of the National Academy of Sciences explores the effects of Saharan dust clouds on atmospheric methane. Its findings have potentially far-reaching implications for understanding the global ...
Most states in the U.S. allow people to use cannabis for medical or recreational purposes. Yet all states want their roadways to be safe. A breathalyzer that can accurately identify people who recently smoked cannabis might ...
In addition to oxygen, nitrogen or carbon dioxide, the air we breathe contains small amounts of organic gases, such as benzene and toluene. These oxidize into small particles or aerosols that contribute to the condensation ...
The haze pollution that frequently occurred in winter in cities of North China has aroused widespread concern. Since the implementation of Air Pollution Prevention and Control Action Plan in 2013, the atmospheric concentration ...
In recent years the plumes of smoke crawling upward from Western wildfires have trended taller, with more smoke and aerosols lofted up where they can spread farther and impact air quality over a wider area. The likely cause ...
