The scale and epistemology of coral bleaching in Papua New Guinea

Coral reefs

Coral bleaching events around the world appear to be increasing in frequency and severity, with the 2002 bleaching events reportedly causing greater coral mortality than those in 1998. The primary driver is global (i.e. excessive CO2 production in industrial countries), while the impact is local, and highly variable. Ecological, and consequent socio-economic impacts of coral bleaching may not be measurable in relatively lightly bleached areas, such as Milne Bay, Papua New Guinea, for perhaps 10 or more years, though medium to long term (10-50 years) impacts might well be dramatic.
