Evidence suggests particulate matter is the air pollutant which poses the greatest threat to global health.

The virtual conferencing that has replaced large, in-person gatherings in the age of COVID-19 represents a drastic reduction in carbon emissions, but those online meetings still come with their own environmental costs, new research from the University of Michigan shows.

New particle formation (NPF) is a major source of aerosol particles in global atmosphere.

The amount of methane released into the atmosphere as a result of coal mining is likely much higher than previously calculated, according to research presented at the annual meeting of the American Geophysical Union recently.

One of President Joe Biden’s first post-inauguration acts was to realign the United States with the Paris climate accord, but a new study led by researchers at the University of California, Irvine demonstrates that rising emissions from human land-use will jeopardize the agreement’s goals without substantial changes in agricultural practices.

It is common practice in climate policy to bundle the climate warming pollutants together and express their total effects in terms of “CO2 equivalence”.

Just along concrete’s gray surface, a chemical reaction is occurring.

A recent McGill study published in Environmental Science and Technology finds that annual methane emissions from abandoned oil and gas (AOG) wells in Canada and the US have been greatly underestimated – by as much as 150% in Canada, and by 20% in the US. Indeed, the research suggests that methane gas emissions from AOG wells are currently the 10th and 11th largest sources of anthropogenic methane emission in the US and Canada, respectively. 

Air pollution is linked to a heightened risk of progressive and irreversible sight loss, known as age related macular degeneration (AMD), reveals a large long term study led by UCL researchers.

Airlines could save fuel and reduce emissions on transatlantic flights by hitching a better ride on the jet stream, new research has shown.
