Global Climate Change Community

The Global Climate Change Community is an ASA Community within the Climatology and Modeling Section.

Climate change encompasses both climatology and modeling. A group is necessary to provide a forum for discussion of approaches for mitigation of climate change and adaptation with respect to agronomic systems. This community's interests include simulation modeling for assessment of impacts, quantification of ecosystem and plant response to climate change, and assessment and measurement of climate related processes like evapotranspiration.

The community has a strong focus on agricultural assessment tools and methods. These need to be developed, tested, and improved in order to provide the most accurate quantitative analyses of climate change impacts on global food security. Recent symposia have focused on model-intercomparison and improvement studies using common datasets and studies that explore and characterize the ability of modeling tools to accurately respond to complex CO2, water, and temperature interactions that accompany climate change predictions.  Goals include identification of common areas of model limitations and successes in order to identify critical knowledge gaps in our analytical tools. The community also seeks to further improve methodology for integrating modeling approaches for specific commodities with geospatial databases and improved climatic and economic models.

Development, dissemination, and application of C x T x W (CO2 x Temperature x Water) datasets for important crops is also of vital interest. A majority of experimental data addresses one or two factors, but not all three, and most data are confounded with local or site-specific soils, climate, and management characteristics.The quality and expanse of available data sets necessarily limits the ability to assess, evaluate, and further improve our models and knowledge. Thus, the community also seeks to bring members from different cropping systems together in a common forum to share such results and identify areas of critical need. Novel measurement approaches or core findings regarding soil-plant-atmosphere interactions are frequently identified and exchanged among members.
