In China, people breathe air thick with the lung-damaging pollutant ozone two to six times more often than people in the United States, Europe, Japan, or South Korea, according to a new assessment. By one metric—total number of days with daily maximum average ozone values (based on an 8-hour average) greater than 70 ppb—China had twice as many high ozone days as Japan and South Korea, three times more than the United States, and six times more than Europe.
China is Hot Spot of Ground-Level Ozone Pollution
CIRES Welcomes Environmental Economist Matt Burgess
As the Fall 2018 semester kicks off at CU Boulder, CIRES welcomes Matt Burgess, an environmental economist, to join its Council of Fellows. Matt Burgess melds ecology, economics, and policy in his work—forming a new connection between CIRES and CU Boulder’s department of Economics.
Wildfire Temperatures Key to Better Understanding Air Quality
When wildfires burn, they don’t only damage land, homes, and businesses. Wildfire emissions, which can be transported over long distances, can be toxic and contribute to the formation of secondary pollutants such as ozone and fine particles in the atmosphere. Those emissions affect human health and the environment, so scientists want to know what’s in wildfire smoke. According to new research from CIRES and NOAA, what matters most is not what kind of fuel is burning, but the temperature at which it burns.
