rculation pattern from General Circulation Models (GCMs) as background (lateral boundary) conditions to simulate climate change at the regional and local (or city) scale. Results from these models can be used to study human impacts such as health impacts, or future water and energy requirements. The authors' analysis of the modeled data, compared with observational data, suggests that extreme climate change should be considered as a possible outcome of greenhouse forcing on the earth-climate system.

WHAT DO LONG-TERM WARMING TRENDS TELL US ABOUT RECENT CLIMATE CHANGE? A LOOK AT THE DYNAMICS OF 20TH CENTURY CLIMATE TRENDS
Chen and colleagues present analysis of 20th century global climate trends, using long-term records to separate for the first time the human-induced trend from shorter-term variations that are unrelated to climate change. The authors discuss the mechanisms behind climate trends, including the weak warming trend perceived in the Pacific Ocean, and contemplate the atmospheric response to the warming that determines how regional climate is changing in the tropics.
