Read here and here. IPCC-friendly green activists got into the Climategate spirit by predicting that 40% of world's coral reefs would disappear by 2010. Like so many before it, this green activist hysterical prediction was totally fabricated out of thin air, having little relationship to reality.
"In 1997 the area of the world's coral reefs was estimated to be 255,000km2. Reference. If the prediction made on 4 Corners is to be believed, then in 2010 the area of the world's coral reefs should be around 153,000km2. Instead, in 2011, one year on from that alarming forecast, we find that the global area of coral reef is estimated to be 249,713km2. Reference. This amounts to a change from 1997 figures of -2.1%. Given the unreported uncertainties, there has essentially been no change in global reef area over the past 10 years. Within error, essentially none of the reefs are missing in 2010."
As is apparently true for all climate science AGW-related predictions, any made by green activists or tax-payer funded scientists is very suspect, especially if it is reported by the mainstream media.
