Report with mini-movie and photos on the hypothesis that the atmospheric transport of dust arising from the desertification in northern Africa led to algal infestation of corals, coral diseases, and the near extinction of associated sea urchins.
Explains the important paleoclimatic information we have obtained from this subaqueous cavern. The time-series data show important contrasts with what would be predicted from orbital theory, provoking extensive scientific discussion.
Homepage for Earth Surface Processes Team with research studies in two general categories: climate change and geologic mapping. Links to research activities, available data sets, workshop, and programs.
How climate change affects ground water is more complex than surface water because the residence time of ground water can range from days to tens of thousands of years. Discusses some broad climatic processes may affect groundwater resources.
Information from climate model forecasts, projections of future flows, paleoclimatic indicators, timing of snowmelt, airborne dust, and the effects on vegetation of troublesome pest species indicate the nature and severity of problems looming.
Direct measurement of an important indicator of interannual variability is extended, using geological proxy measures, farther back in time to well before modern measurements were made. This tells us about the history of climate variability.
Accelerating loss of mass, weakening correlation with the Pacific Decadal Oscillation, and increasing mass turnover likely are the result of changes to warmer and drier climate conditions that are affecting three well-studied glaciers.
