“Climate Researchers are increasingly interested in analyzing spatio-temporal trends for environmental and ecological processes that are viewed as “bioindicators” of climate change (e.g., changes in migratory patterns of birds, changes in intensity and frequency of precipitation events, floods, tornadoes and hurricanes). In particular, there is interest in modeling uncertainty for these processes using statistical methods, as a result of the recent debates over global warming of the earth’s climate. The complexity, and often high-dimensionality, of these processes exhibited through different scales of spatial and temporal variability necessitates the implementation of statistical models applicable to very large data sets. In this work, we present a general framework for computationally efficient spatio-temporal trend analysis of environmental and ecological processes with linkage to climatological effects. The proposed approach allows climate researchers to investigate spatial and temporal patterns of environmental and ecological response to climate events. Finally, example applications of the proposed approach will be discussed.”
