Reductions in Air Pollutants Without Greenhouse Gas Cuts Could Increase Global Warming

As countries around the world race to mitigate global warming by limiting carbon dioxide emissions, an unlikely source could be making climate goals harder to achieve without even deeper cuts in greenhouse gas production: reductions in air pollution.

Scientists Design a Curved Barrier to Protect People from Air Pollution

A unique curved barrier has been designed by researchers at Imperial College London, who publish new findings in the peer-reviewed journal Cities & Health on how the structure can protect people from the damaging effects of air pollution.

Study Provides a Detailed Accounting of Cannabis Industry's Carbon Footprint

It's no secret that the United States' $13 billion cannabis industry is big business. Less obvious to many is the environmental toll this booming business is taking, in the form of greenhouse gas emissions from commercial, mostly indoor production.

Tougher Environmental Policies Push Firms to Pollute in Countries with Lenient Regulations

Multinational companies headquartered in countries with tougher environmental policies tend to locate their polluting factories in countries with more lax regulations, a new study finds.

Wildfire-Produced PM2.5 More Harmful to Respiratory Health than Other Particulate Pollutants

Researchers at Scripps Institution of Oceanography at UC San Diego examining 14 years of hospital admissions data conclude that the fine particles in wildfire smoke can be several times more harmful to human respiratory health than particulate matter from other sources such as car exhaust. While this distinction has been previously identified in laboratory experiments, the new study confirms it at the population level.

Traffic Restrictions During Lockdown Led to a Sharp Decline in Air Pollutant Emissions

At the starting of the Corona pandemic in March 2020, the extensive mobility restrictions created a special condition for atmospheric sciences.

Model Predicts Transition Paths of Marine Debris into Ocean Garbage Patches

Tons of plastic debris get released into the ocean every day, and most of it accumulates within the middle of garbage patches, which tend to float on the oceans' surface in the center of each of their regions. The most infamous one, known as the Great Pacific Garbage Patch, is in the North Pacific Ocean.

Study Highlights the Unintended Beneficial Side Effect of Clean Air Act

Removal of pollutants from the air, or atmospheric deposition, is a natural cleaning mechanism. However, the removed toxic matters don't just disappear on the Earth. China's Soil Pollution Survey released in 2014 shows that 19.4% of the Chinese farmland soil was polluted and 82% of pollutant was toxic heavy metals such as cadmium, which can cause chronic health problems.

OU Researchers Identify the Limits and Insufficiency of Major Greenhouse Emission Database

A University of Oklahoma-led study published in 2020 revealed that both area and plant growth of paddy rice is significantly related to the spatial-temporal dynamics of atmospheric methane concentration in monsoon Asia, where 87% of the world's paddy rice fields are situated.

Sea Turtles are Sentinels and Victims of Plastic Pollution in the Adriatic Sea

Sea turtles are witnesses and victims of the high level of plastic pollution of the Adriatic Sea. A group of researchers at the University of Bologna analysed 45 turtles hospitalised at Fondazione Cetacea in Riccione and found plastic debris in their faeces.
