Integrating modeling and empirical approaches to improve predictions of tropical forest responses to global warming


First Meeting:  April 26-May 2, 2014


Tropical forests contain > 50% of the world’s known species (Heywood 1995), 55% of global forest biomass (Pan et al. 2011), and exchange more carbon (C), water and energy with the atmosphere than any other ecosystem type (e.g., Saugier et al. 2001). Despite their importance, there is more uncertainty associated with predictions of how tropical forests will respond to warming than for any other biome (Randerson et al. 2009). This uncertainty is of global concern due to the large quantity of C cycled by these forests and the high potential for biodiversity loss. Given the importance of tropical forests, decision makers and land managers around the globe need increased predictive capacity regarding how tropical forests will respond to climatic change.

This week we brought together modelers and empiricists to evaluate and compare predictions of tropical forest response to increased temperature at a variety of temporal and spatial scales. Our goals include the following:  First, we will model and critically evaluate the responses of a range of tropical forest sites to increased temperature using a selection of models that operate at multiple scales and specialize in different processes. Results will greatly help constrain expected tropical forest responses and will be used to generate hypotheses for a future tropical forest warming experiment in Puerto Rico. Second, we will develop strategies and proposals with the goal of linking three finer-scale models to a larger, global-scale model in order to improve the predictive capacity of the global-scale model. Instead of collecting new data or focusing on a single model, these workshops will build upon current knowledge to amass existing datasets and take advantage of a suite of models. Exceptional scientists in the appropriate fields have agreed to participate in these meetings. The Powell Center is the perfect venue for this endeavor due to its focus on facilitating data synthesis and cross-disciplinary scientific communication. The US Forest Service and INTERFACE (a NSF Research Coordination Network) also strongly support the meetings.
