It makes an important contribution to the scientific understanding we have of the role of aviation for climate change—an understanding decision-makers and politicians may need on the way to achieving the goals of the Paris Agreement. In the new study, we have analyzed 20 years of aviation emissions, up until and including 2018.

CSIRO scientists have developed a new way to account for ozone in computer simulations of the climate. This latest modeling shows that the oceans take much less ozone out of the atmosphere than previously thought. Ozone (O 3 ) is formed by reactions of chemicals such as nitrogen oxides and volatile organic compounds—i.e.,

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.

Long-term exposure to ambient air pollutants, especially O 3 (ozone), is significantly associated with increasing emphysema, according to a new study led by the University of Washington, Columbia University and the University at Buffalo. The annual averages of ozone levels in study areas were between about 10 and 25 ppb.

The action finalizes parts of the SAFE Vehicles Rule that was first proposed on 2 August 2018. The California waiver authority exists because California has uniquely difficult problems with ozone-forming pollutants. Earlier post.)

Now, an international team of researchers have shown, in an open-access paper published in the journal Nature Communications , that concentrations were increasing at an all-time record by 2018. When we saw the reports of enormous emissions reductions from India and China, we were excited to take a close look at the atmospheric data.

From 10 March to 9 April 2018, the German Aerospace Centre (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is conducting research flights from Tainan in Taiwan more closely to examine the spread and transformation of emissions from major cities such as Manila, Taipei, Seoul, Tokyo, Beijing, Shanghai and Guangzhou.
