McCarthy says that despite anxiety at the agency about the election results, she is confident in EPA’s work and that efforts to control climate change will continue.
Pollution: urban and regional
Air Pollutant Plays Lesser Role in Climate Change Than Expected
Satellite data indicate that pollution control efforts that curbed levels of sulfur dioxide gas did not cause a major decrease in carbon dioxide absorption by plants.
No Evidence for Unknown Source of Ozone Precursor
A study suggests that known combustion and photochemical sources of nitrous acid, a precursor to ground-level ozone, are enough to explain levels seen in the atmosphere.
Atmospheric Chemists Should Tackle Risks to Society, Report Says
Protecting public health and the health of the climate and ecosystems warrants more focus from this scientific field, according to the report.
Chemical Boosts Ozone Production over Southern China
The presence of nitryl chloride in polluted urban air can enhance the production of ozone by up to 41%, according to a new modeling study constrained by ground-based measurements.
Evaluating the Impact of Maryland's Healthy Air Act
Reducing emissions of short-lived gaseous sulfur pollutants from power plants had an immediate, local benefit, but controlling longer-lasting harmful particulate matter will require regional action.
The High Cost of Switching Power Sources
Researchers construct a world where nuclear energy everywhere is replaced with coal, with stark consequences for human health and the environment.
Court Delay on U.S. Climate Plan Won't Stop Clean Energy Efforts
While many states wait for judicial clarity, analysts predict that the move toward clean energy and emissions reductions will continue.
Detecting Black Carbon in the Arctic Atmosphere
Measurements of light-absorbing carbon particles made during an Arctic research expedition could improve understanding of their effects on the Arctic climate.
Mercury in Rain Increasing in Western and Central United States
Despite tightening emissions rules, mercury concentrations are rising in rainfall wetting western and central regions of the United States. The pollutant may waft in from Asia, scientists speculate.
