March 2017: RGCM white paper on High Latitude Earth System Processes and Feedbacks
The RGCM program supports a significant research effort in high-latitude Earth Systems science. We worked with the greater RGCM science community to develop a white paper that presents a community view of priorities for high-latitude Earth Systems science. The white paper identifies four Grand Challenges in this area, and discusses goals, current capabilities, gaps, and research needs and opportunities within the context of these Grand Challenges. It was written as a deliverable of the RGCM PI meeting (November 2016).

January 2017: New webinar series
We are starting a new webinar series for DOE's RGCM program, with as theme "High-Latitude Climate Processes and Feedbacks". This webinar series aims to increase awareness of the many high-latitude climate science activities across different RGCM-funded projects. Our inaugural season will feature 6 sessions, with 2 speakers each.
