The role of climate and weather in understanding, predicting, and reducing the impact of COVID-19 is not well understood. This summary highlights both operational and research recommendations for meteorological services around the world to more effectively provide services that support COVID response and recovery.

The Climate and Health Outlook from HHS & NOAA, which launched on May 6, serves as a resource to help people, health professionals, and communities protect individual and community health impacted by climate events.

ENSO is a major source of seasonal predictability and driver of global climate and extreme events.

New research demonstrates the presence of solid organic-coated ammonium sulfate particles in the Arctic boundary layer. As the Arctic loses ice, researchers expect to see more of these unique particles formed from oceanic emissions combined with ammonia from birds, that can change how clouds form and climate.

During the last week of March, US CLIVAR held a hybrid workshop on multi-year climate predictions.
