Editorial: Climate change: Regionalizing a global phenomenon

J. Hay

This issue of Weather and Climate contains papers which may, at first glance, have little in common. But each one can be linked to the topic of climate change, and especially to the pressing need for regional characterization and interpretation of this global phenomenon. The recently released Second Assessment Report (SAR) of the Intergovernmental Panel on Climate Change (IPCC) established a place in scientific history with the conclusion that "the balance of evidence suggests a discernible human influence on global climate". However, such advances in attributing the causes, and in describing the future patterns, of global climate change serve to highlight the growing gaps in understanding and predictive capability between the global and regional scales. Indeed, after reading the SAR one is left with the uncomfortable feeling that time spent endeavouring to reach an international consensus has been at the expense of studies that explore, explain and exploit regional differences.
