Climate Change

Early Hominin Environments in the Turkana Basin, Kenya.

Thure Cerling is a pioneer in the use of stable isotopes of Carbon, Nitrogen and Oxygen to study historic changes in CO2 levels in the Earth’s atmosphere. He was elected to the National Academy of Sciences in 2001.  In recent years he’s used stable isotopes to analyze hair, teeth and bone to better understand the impacts of changing CO2 levels on habitat, animals and man.

South America Weather Forecast: Gastrointestinal Disease Likely

Climate scientists predict that climate change will lead to increased variability in precipitation over much of South America.  Research by Carlton et al (2013) on residents of northwestern rural Ecuador who rely on streams and rivers for their drinking water shows how those changes might impact water quality and associated rates of diarrhea, a water-related disease which leads to approximately 1 million deaths of young children worldwide each year.  The study further highlighted curious dynamics involving precipitation and water-borne disease.
