With intense wildfires in the western U.S. and frequent, intense hurricanes in the Gulf of Mexico, the nation is again affected by extreme weather-related events resulting from climate change. In response, cities, states and regions across the country are developing policies to reduce their emissions of greenhouse gases, chiefly carbon dioxide (CO2). Even though many state and local governments are committed to these goals, however, the emissions data they… Read more

NAU research team sees major shift in relationship between state-by-state traffic and COVID-19 cases, offering insights into outcomes of lockdown policies
The upper left panel shows that during the month of March 2020, the decline in traffic across the US coincided with the rise in COVID-19 cases. The country responded in a uniform fashion. The lower panel shows how that correlation in traffic-COVID-19 broke down with traffic rising in most states but COVID-19 cases rising in… Read moreNAU’s Vulcan Project fossil fuel emissions show best match to carbon-14 measurements
Study findings take a dramatic step towards a greenhouse gas information system that can fundamentally change the way cities, states and the nation tackle the climate change problem
Results from Northern Arizona University’s Vulcan Project estimating carbon dioxide (CO2) emissions from fossil fuel combustion for the entire U.S. show very close agreement to a new atmospheric-based approach for estimating these same emissions, as reported in a paper… Read more
NAU atmospheric scientist says US carbon dioxide emissions have dropped to unprecedented levels during pandemic
As the demand for transportation fuels has plummeted at an unprecedented rate in the last month due to the COVID-19 pandemic, a Northern Arizona University scientist says the dramatic decrease in local air pollution and carbon dioxide (CO2) levels above cities is significant, measurable and could be historic, depending on how long commuters and other drivers… Read more
NAU scientist maps CO2 emissions for entire Los Angeles Megacity to help improve environmental policymaking
As the threat of global warming grows—and with it, the specter of more extreme conditions such as wildfires, droughts and tropical storms—cities across the U.S. are developing policies to reduce their emissions of greenhouse gases, chiefly carbon dioxide (CO2). Even though many local governments are committed to these goals, however, the emissions data they have… Read more
