Researchers led by Prof. Zhang Weijun from the Hefei Institutes of Â鶹ÒùÔºical Science (HFIPS) of the Chinese Academy of Sciences (CAS) have found that a decrease of about 35% of single scattering albedo (SSA) at 365–405 nm ...
People once believed the planet could always accommodate us. That the resilience of the Earth system meant nature would always provide. But we now know this is not necessarily the case. As big as the world is, our impact ...
The COVID pandemic shutdowns in South Asia greatly reduced the concentration of short-lived cooling particles in the air, while the concentration of long-lived greenhouse gases was barely affected. Researchers were thus able ...
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 ...
The Brazilian rainforest is one of the world's few continental regions with clean air. However, this is only true during the wet season, when the concentration of particulate matter is very low. During the dry season, it's ...
Our industrialized society releases many and various pollutants into the world. Combustion in particular produces aerosol mass including black carbon. Although this only accounts for a small percentage of aerosol particles, ...
An international team led by researchers from the Institute of Atmospheric Â鶹ÒùÔºics (IAP) of the Chinese Academy of Sciences has detected aerosols from the Hunga Tonga eruption in the Northern Hemisphere stratospheric westerlies ...
Using a new detection method, UC Riverside scientists found a massive amount of methane, a super-potent greenhouse gas, coming from wildfires—a source not currently being accounted for by state air quality managers.
Tiny aerosols particles in the atmosphere have a significant effect on the climate. They affect the climate directly by interacting with solar radiation. Depending on the type of particle, they can block sunlight, cooling ...
New analysis has found increasing emissions of several ozone-depleting chemicals despite their production being banned for most uses under the Montreal Protocol—and a loophole in the rules is likely responsible.
