Ozone levels across much of North America and Europe dropped significantly between 2000 and 2014. People living in parts of southern Europe, South Korea and southern Japan and China also experienced more than 15 days a year of ozone levels above 70 ppb. Source: University of Leicester.

In the new study, we have analyzed 20 years of aviation emissions, up until and including 2018. Net warming from NO x emissions is a sum over warming (short-term ozone increase) and cooling (decreases in methane and stratospheric water vapor, and a long-term decrease in ozone) terms. For 2018 the net aviation ERF is +100.9

The California Air Resources Board released GHG emissions data for 2018 showing that emissions remain below 1990 levels but are effectively flat compared to 2017, while the economy grew by 4.3%. Total statewide 2018 GHG emissions were 425.3 million metric tons between 2017 and 2018, the first such decline since 2013.

SLCPs are a category of pollutants which remain in the atmosphere for a relatively brief period, but have global warming potentials that are much higher than those of CO 2. SLCPs may account for an estimated 40% of global warming, increasing the impacts of climate change. CO 2 remains in the atmosphere for up to a century.
