About the Workshop
This AGCI session will tackle the formidable science issues involved with designing and running short term climate projections (now more commonly referred to as "decadal prediction"). The session will also address the important issues of the utility and applications of this information for decision support and impacts research. Proposed output from this session is a white paper and possible journal article summarizing our current state of knowledge on decadal prediction, the degree of success one could expect from such experiments, possible solutions to the scientific challenges involved with this problem, and an assessment of how this type of climate change information over could be used for decision support and impacts analyses the next few decades...Read Complete Session Description |

Weather and Climate Extremes in a Changing Climate
25-29 June 2007 |
- Session organizers: Tom Karl, Gerald Meehl, Bill Murray and Chris Miller
- Agency leads: Tom Karl, Chris Miller, Anjuli Bamzai, Don Anderson, Tsengdar Lee and Tom Armstrong
- This session marks the third in a series on the critical topic of climate extremes. The goal of the 2007 meeting was to develop and summarize the scientific understanding of weather and climate extremes for the United States Climate Change Science Program (CCSP). The meeting sought to fulfill the CCSP extremes climate component Goal 3: “to reduce uncertainty in projections of how the Earth’s climate and related systems may change in the future.”
- Scientists discussed the most recent findings on extremes, including new modeling techniques and data from recent studies (such as studies on the frequency and intensity of hurricanes).
- Output included a draft CCSP report on key research issues.

Northern Eurasia Land Surface Properties and Change and Its Role in the Global Earth System
12-17 August 2007 |
- Workshop Conveners: Guy Brasseur, Kathy Hibbard, Vladimir Romanovsky, Irina Sokolik, and Pavel Groisman
- Background: Northern Eurasia is undergoing rapid and significant changes associated with changing climate and socio-economic patterns from the 20th century to present. Climatic changes over the largest landmass in the northern extratropics interact and affect the rate of the global change through atmospheric circulation and through strong biogeophysical and biogeochemical feedbacks. How these feedbacks impact the greater global system is largely unknown. Studies of environmental processes in this region are, therefore, an important contribution to reducing uncertainties in our understanding of global change beyond the domain of Northern Eurasia.
- About the Workshop: This Northern Eurasia Earth Science Partnership Initiative (NEESPI) workshop tackled how to incorporate regional biophysical feedbacks associated with terrestria in the northern high latitudes, a key issue for emerging earth system models. Disucssions included:
- changes in permafrost and their interaction with terrestrial carbon (methane and CO2 emissions);
- potentially dramatic land cover changes that may affect regional and global energy, water, and biogeochemical cycles, including atmospheric aerosol loading;
- strong climatic changes affecting and being affected by all the above and how to represent them in climate and Earth system models; and
- social processes that intertwine and feed back to environmental changes in the region and beyond.
- Output: A summary of the Aspen Global Change Institute's 2007 summer science session "Northern Eurasia Land Surface Properties and Change and Its Role in the Global Earthy System" was published in the November 2007 edition of Eos. The synopsis emphasizes Northern Eurasia's global importance and stresses the need for comparing models across multiple high latitude regions. The supplementary material highlights the current status, points to the major deficiencies in the data and knowledge, and suggests the future objectives for research in the high-latitude region.
