African air quality: framework for a proactive observing and modeling strategy

AC4 News / By

The public health threat of air pollution in Africa, which already results in 1.1 million premature deaths annually, is expected to intensify under rapid urbanization and population growth. To develop strategies for improving air quality monitoring and research in East Africa, scientists from around the world convened for workshops virtually in 2021 and in-person in […]

Improving extreme rainfall predictions: the limits of high-resolution climate models

CAP/RISA News, COM News, MAPP News, NIDIS News / By

The Climate Program Office supported a new study published in Earth’s Future that advances efforts to improve projections of how extreme rainfall will increase as global temperatures rise. Extreme rainfall events have significant environmental and societal impacts such as floods or water shortages. The general circulation models scientists use to predict extreme rainfall trends typically

New discovery in atmospheric chemistry helps predict methane’s role in climate change

Earth System Science and Modeling (ESSM), Earth's Radiation Budget (ERB), ERB News / By

In a study published in Science, scientists describe a newly discovered reaction that improves modeling of methane in the atmosphere. Modeling methane’s atmospheric lifetime is important to understanding how the potent greenhouse gas contributes to climate change. To date, models consistently overestimate the amount of hydroxyl radicals (OH), the molecules responsible for breaking down methane,
