An introduction to trends in extreme weather and climate events: Observations, socioeconomic impacts, terrestrial ecological impacts, and model projections

Weather and climatic extremes can have serious and damaging effects on huma n society and infrastructure as well as on ecosystems and wildlife. Thus, t hey are usually the main focus of attention of the news media in reports on climate. There are some indications from observations concerning how clima tic extremes may have changed in the past. Climate models show how they cou ld change in the future either due to natural climate fluctuations or under conditions of greenhouse gas-induced warming. These observed and modeled c hanges relate directly to the understanding of socioeconomic and ecological impacts related to extremes.
