Earth’s surface air temperature has significantly increased over the 20th century, although this overall global warming has been punctuated by periods of weaker/stalled warming or even cooling. Research suggests that shifts in the circulation of the Pacific Ocean and atmosphere have played a key role in the present hiatus’ development.

In early January 2014, an Arctic air outbreak brought extreme cold and heavy snowfall to central and eastern North America, causing widespread disruption and monetary losses. However, new research by Screen et al., using state-of-the-art climate model simulations, finds that the risk of North American daily cold extremes decreases in the future.

On May 23-25, 2016, paleoceangraphy and physical oceanography researchers will gather for a workshop on Connecting Paleo and Modern Oceanographic Data to Understand AMOC over Decades to Centuries. Participation will be limited to 60 people. Applications are due by January 21. 

Over the coming decades, the tropical Pacific is likely to experience more extreme sea level swings on timescales of several years. The culprit is a change in the El Niño-Southern Oscillation and its characteristic Pacific wind response, according to a new study using CMIP5 climate change projections.

Arid and semi-arid regions are projected to experience the most adverse impacts of climate change. Intensifying drought and precipitation extremes are found in the observational record and current global climate projections according to the recent IPCC report.

Remote participation will be available during the plenary sessions of the upcoming workshop, Translating Process Understanding to Improve Climate Models, to be held October 15-16 at NOAA GFDL. Registration must be received before the workshop begins. Remote participants will be able to ask questions via a chat box. 

Video recordings and presentations are now available for the Observing & Modeling Climate Variability in the Intra-Americas Seas & Impacts on the Continental Americas & the Caribbean workshop. Also check out the posters in the gallery and submit questions/comments by September 23.

Bringing together members of the community, the 2015 Summit featured scientific and programmatic presentations and engaging discussions to advance activities of the US CLIVAR program. These presentations are now available online, as well as a video highlighting the talks from the special science session on "Understanding the Earth's Climate Warming Hiatus."

Requests are now being accepted for US CLIVAR-sponsored workshops and working groups. The call for submissions is open to the US climate science community. The deadline for submission is October 2. 

Extreme precipitation and associated flooding has a high societal and economic cost. In the Northeast US extreme precipitation has increased by more than 70% in the last 50 years and is projected to continue to increase.
