Summary
Global warming is believed to cause global-scale climate changes such as rise in sea level and increased precipitation. However, these long-term changes are not uniform temporally and spatially. Reliable and accurate predictions of regional climate change are important for mitigation/adaptation. Climate change studies largely depend on climate simulations and predictions with numerical climate models. However, the simulated patterns of climate change with current models are still uncertain and inconsistent with historical observations. Another issue in climate studies is that many climate data sets are affected by time-varying observational bias errors, making it difficult to identify reliable patterns of climate change. I will talk about how we tackle and detect realistic regional patterns of climate change by comparing bias-reduced climate data sets and climate models.
