"Emissions of nitrous oxide, a climate super-pollutant hundreds of times more potent than carbon dioxide, are rising faster than previously thought—at a rate that not only threatens international targets to limit global warming, but is consistent with a worst-case trajectory for climate change, a new study suggests."
Anything related to air quality, air pollution, or the atmosphere
"The Centers for Disease Control and Prevention now says the coronavirus can be spread through airborne particles that can linger in the air "for minutes or even hours" — even among people who are more than 6 feet apart."
When it comes to climate change, coal’s carbon emissions mean trouble. But as Backgrounder explains, if the once-powerful coal industry is on the decline in the United States, the fuel’s still finding favor worldwide. And that’s bad news for the Paris climate accord’s hopes of gaining control of runaway warming. The story behind the “exaggerated death” of coal.
Keeping tabs on the increasingly frequent closing of U.S. coal-fired electric power plants is an important way to follow developments on the larger climate change beat. The latest Reporter’s Toolbox points to several mapping databases that help make the job far easier — whether watching the industry in the United States or abroad.
"Fires in Brazil’s Amazon increased 13% in the first nine months of the year compared with a year ago, as the rainforest region experiences its worst rash of fires in a decade, data from space research agency Inpe showed on Thursday."
"The Environmental Protection Agency (EPA) on Thursday finalized a rule that could reclassify many “major” sources of pollution as minor ones, allowing facilities to abide by less-stringent emissions standards for dangerous substances such as mercury, lead and arsenic."
"California will ban the sale of new gasoline-powered cars to combat climate change starting in 2035, a move that could help reshape the nation’s automobile market and its output of greenhouse gases."
"Power plants, refineries, and other industrial sources may now be able to avoid stringent pollution controls if the toxic air particles they emit fall below a mandated legal threshold."
"Asphalt—a petroleum product used on roads and roofs—is a significant source of harmful chemicals that end up contributing to ozone and particulate matter pollution, according to a study published today in Science Advances."
"The Centers for Disease Control and Prevention posted guidance Friday evening saying that aerosol transmission might be one of the "most common" ways the coronavirus is spreading — and then took the guidance down on Monday."
