A variety of means exist by which earth scientists study environmental change on geologic timescales; in particular, organic molecules preserved in ocean and lake sediments can be used to reconstruct the histories of monsoons, El Niño, and other massive weather events on thousand- to million-year timescales. Constraining the past meteorological changes that occur in response to deglaciation, insolation, and rising levels of greenhouse gases helps climate modelers project trends into the near future as anthropogenic warming continues. In turn, better-informed models and predictions have the potential to characterize particularly high-risk regions and thus ameliorate the impacts of weather-driven, climate-ampli ed natural disasters.
