Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 61. The effects of increased atmospheric carbon dioxide and related climate change on shallow coral reefs are gaining considerable attention for scientific and economic reasons worldwide. Although increased scientific research has improved our understanding of the response of coral reefs to climate change, we still lack key information that can help guide reef management. Research and monitoring of coral reef ecosystems over the past few decades have documented two major threats related to increasing concentrations of atmospheric CO2: (1) increased sea surface temperatures and (2) increased seawater acidity (lower pH). Higher atmospheric CO2 levels have resulted in rising sea surface temperatures and proven to be an acute threat to corals and other reef-dwelling organisms. Short periods (days) of elevated sea surface temperatures by as little as 1–2°C above the normal maximum temperature has led to more frequent and more widespread episodes of coral bleaching-the expulsion of symbiotic algae. A more chronic consequence of increasing atmospheric CO2 is the lowering of pH of surface waters, which affects the rate at which corals and other reef organisms secrete and build their calcium carbonate skeletons. Average pH of the surface ocean has already decreased by an estimated 0.1 unit since preindustrial times, and will continue to decline in concert with rising atmospheric CO2. These climate-related Stressors combined with other direct anthropogenic assaults, such as overfishing and pollution, weaken reef organisms and increase their susceptibility to disease.

Coral reefs are the largest landforms built by plants and animals. Their study therefore incorporates a wide range of disciplines. This encyclopedia approaches coral reefs from an earth science perspective, concentrating especially on modern reefs. Currently coral reefs are under high stress, most prominently from climate change with changes to water temperature, sea level and ocean acidification particularly damaging. Modern reefs have evolved through the massive environmental changes of the Quaternary with long periods of exposure during glacially lowered sea level periods and short periods of interglacial growth. The entries in this encyclopedia condense the large amount of work carried out since Charles Darwin first attempted to understand reef evolution. Leading authorities from many countries have contributed to the entries covering areas of geology, geography and ecology, providing comprehensive access to the most up-to-date research on the structure, form and processes operating on Quaternary coral reefs.

"Coral reefs throughout the world are subjected to a number of anthropogenic stressors. Some of the most pervasive of these are a result of climate change. Increasing sea surface temperature of the world's oceans is resulting in unprecedented, mass coral bleaching events wherein coral polyps expel their symbiotic zooxanthellae. Research also suggests these disturbances make coral reefs more susceptible to disease. Occurrences of mass bleaching and disease outbreaks prompted the U.S. National Oceanic and Atmospheric Administration (NOAA) to create Coral Reef Watch, a program that monitors many of the indicators of these events using satellites. Coral Reef Watch provides coral reef managers with near-realtime alerts of bleaching conditions as they develop. For Coral Reef Watch to adequately monitor the environmental conditions of coral reefs throughout the world, it is imperative that collaborations exist between coral reef ecosystem biologists, managers and remote sensing scientists. This technical report documents a workshop held in 2010 in which experts from around the world convened to share information and brainstorm about threats to coral reef ecosystems as a result of climate change. In addition, these experts discussed additional risks to coral reefs and potential remote sensing tools that could be developed in order to monitor the threats. This technical report provides substantive information on experts' current understandings of coral reef biology, best management practices for coral reef ecosystem management, and technical considerations for using environmental remote sensing to aid in these research and managerial pursuits"--Abstract.
