Kessenich et al. (2025) analyzes projected changes in CONUS fire weather and compares the responses of multiple fire indices using 13 dynamically downscaled regional climate models from North America CORDEX for the historical reference (1980–2010), mid-century (2030–2060), and end-of-century (2069–2099) periods.

Using a local energetics framework, Brizuela et al. (2025) find that 20-50% of equatorial Pacific upwelling is not driven by local winds but by potential energy stored in the tropical thermocline.

Kamnani et al. (2025) present the first systematic global assessment of how consistently different regions exhibit a dominant atmospheric river (AR) season, tracking how often regional peaks repeat across regions and detection methods.

The 2025 US CLIVAR Summit, held in Boulder this past July, included three plenary sessions and 13 breakouts on a range of pressing climate variability and change science topics. The report is now available.

Villas Bôas, Marechal, and Bohé (2025) leverage data from SWOT’s Ka-band Radar Interferometer (KaRIn) to explore the first-ever two-dimensional (2D) maps of significant wave height (Hs) at kilometer-scale resolution. These novel observations enable detailed investigation of how waves, winds, and currents interact across a wide range of scales and ocean conditions.

The latest news, research highlights, webinars, data sets, meetings, funding, career opportunities, and jobs for the climate science community.

The joint OCB/US CLIVAR Pathways Connecting Climate Changes to the Deep Ocean Workshop report reviews the discussions and recommendations of the workshop that took place April 2024. Key topics include fast and slow pathways connecting the ocean surface to deep and methods for observing and modeling these pathways.

Hosted by the US CLIVAR Working Group on Accelerating Research on the Scientific Foundations of Regional Climate Risk Information, this webinar series explores the growing demand for actionable information on climate hazards and risks.
