All Scientists are Sceptics ~Professor Bob Carter

Whenever someone asserts that a scientific question is “settled,” they tell me immediately that they don’t understand the first thing about science. Science is never settled. Dr David Deming

Perhaps the most frustrating aspect of the science of climate change is the lack of any real substance in attempts to justify the hypothesis ~Professor Stewart Franks

Coral Reefs are "Climate-Change" Proof

How often have you heard that due to Anthropogenic (man-made) Global Warming, the Great Barrier reef is in danger.

Recently Julia Gillard told Fairfax Radio:
"Our great tourist assets are highly sensitive to climate change, the Great Barrier Reef to take one example. That's a wonderful natural asset for our country but it also supports around 60,000 jobs in the tourism industry."
In a media Release from Greg Combet:
"The Australian Government is committed to protecting the fragile eco-system of the Great Barrier Reef from the impacts of climate change and safeguarding the livelihoods of the industries and communities that depend on it," Mr Combet said.
Prominent reef scientist Ove Hoegh-Guldberg said in April the reef would die unless carbon emissions were dramatically cut within the next decade.

Now the Gillard Green Government can forget their worries (or is it their scare tactics) about the Great Barrier Reef. A new paper has been published:

Reference
Bauman, A.G., Baird, A.H. and Cavalcante, G.H. 2011. Coral reproduction in the world's warmest reefs: southern Persian Gulf (Dubai, United Arab Emirates). Coral Reefs 30: 405-413. 



What was learned
The three researchers report that the reproductive biology of the six coral species in the southern Persian Gulf "appears to be well adapted to extreme annual environmental fluctuations" and is "remarkably similar to conspecifics elsewhere in the Indo-Pacific (Baird et al., 2009a,b)," adding that "the adaptive capacity of corals in the Persian Gulf is likely facilitated by a combination of short-term acclimation in individuals during acute environmental conditions (e.g., recurrent bleaching events) and long-term adaptation among coral populations to chronic environmental conditions (e.g., extreme temperatures)."

What it means
In concluding their analysis of their data, Bauman et al. say their work "confirms that corals are capable of reproductive activities under extreme environmental conditions," as has also been found to be the case by Coles and Fadlallah (1991) and Coles and Brown (2003). Hence, they state that "coral populations can survive and proliferate in extreme conditions that are projected to occur in many other regions of the world by the end of this century," buttressing their claim with the statement that "the recovery of these coral assemblages following mortality induced by a number of recent temperature-related bleaching events (1996, 1998 and 2002) suggests these assemblages are also resilient to extreme fluctuations in water temperature," additionally citing in this regard the work of Riegl (1999, 2003) and Burt et al. (2008).

  1. Environmentalists never give nature any credit, do they?
