Effects of Way-Above-Average Warming on Tasmanian Reefs
Stuart-Smith, R.D., Barrett, N.S., Stevenson, D.G. and Edgar, G.J. 2010. Stability in temperate reef communities over a decadal time scale despite concurrent ocean warming. Global Change Biology 16: 122-134.
Contrary to what they had expected to find, the four researchers discovered that "Tasmanian shallow rocky reef communities have been relative stable over the past decade," in spite of the "substantial rise in sea surface temperature over this period" and the "continuation of a considerable warming trend in oceanographic conditions over the last 50 years." Indeed, they report that "the northeast and southeast bioregions, which are most influenced by the East Australian Current and hence have experienced the greatest warming over the last century, appeared to have actually changed very little," adding that "not only were Tasmanian reef communities remarkably similar between 1994 and 2006 in a multivariate sense, but univariate community characteristics such as species richness and total fish abundance were also consistent." Thus, contrary to many people's expectations, as well as their own initial thoughts on the subject, the Australian scientists found very little evidence to support the "doomsday" scenarios of the IPCC, who foresee continued global warming decimating earth's highly productive costal marine ecosystems.
