Coral Reefs and Climate Change: Unproved Assumptions

Maynard, J.A., Baird, A.H. and Pratchett, M.S. 2008b. Revisiting the Cassandra syndrome; the changing climate of coral reef research. Coral Reefs 27: 745-749.

Via CO2 Science: In an article recently published in the scientific journal Coral Reefs, Maynard et al. (2008b) question the wisdom of "popularising predictions based on essentially untested assumptions," among which assumptions they list the common climate-alarmist claims that: (1) "all corals live close to their thermal limits," and (2) "corals cannot adapt/acclimatise to rapid rates of change."

The three researchers clearly believe there is (an adaptive response,) stating that "a number of studies suggest that bleaching mortality rates have declined and thermal tolerance has increased in some regions." As one example, they report that "mortality rates in the Eastern Pacific were significantly lower in 1998 when compared with 1982 and 1983 (Glynn et al., 2001)," while as another example they write that "Maynard et al. (2008a) found thermal tolerance of three common coral genera on the Great Barrier Reef to be greater in 2002 than that expected from the relationship between temperature stress and bleaching severity observed in 1998."

More scientists proving what locals and well known reef divers such as Ben Cropp have maintained.
