Implies that changes in carbon dioxide levels preceded changes in global temperature. The opposite is true. Historically, temperature changes have preceded CO2 changes. Hubertus Fischer, Scripps Institution of Oceanography, Geosciences Research Division, University of California San Diego, La Jolla, CA Blames global warming for the decline “since the 1960s” of the Emperor Penguin population in Antarctica. In fact, the decline took place in the 1970s—possibly due to the advent of Antarctic ecotourism—and the population has been stable since the late 1980s. Christophe Barbraud, Centre détudes Biologiques de Chizé, Centre National de la Recherche Scientifique, Bois, France Warns that global warming is destroying coral reefs, even though today’s main reef builders evolved and thrived during periods when the world was 10-15°C warmer than the present. Center for the Study of Carbon Dioxide and Global Change Blames global warming for the severe drought that hit the Amazon in 2005. “It is not possible to link the drought to global warming.” Gavin Schmidt of NASA, Michael Mann of the University of Virginia Blames global warming for the disappearance of Lake Chad, a disaster more likely stemming from a combination of regional climate variability and societal factors such as overgrazing. Martin Hoerling, National Oceanic and Atmospheric Administration Earth System Research Laboratory, Boulder, Colorado Asserts that a sea-level rise of 20 feet is a realistic short-term prospect. The IPCC predicts the increase in sea level will be one foot. Claims that Nairobi, Kenya, was malaria-free until recent global warming. In fact, malaria epidemics were common in Nairobi during the 1920s to the 1940s. The resurgence of malaria in East Africa is due to decreased spraying of homes with DDT. Simon I. Hay, Department of Zoology, University of Oxford, United Kingdom Claims that climate history from ice cores proves the Medieval Warm Period was “tiny” comp
