We are familiar with the notion of getting an expert second opinion when an expert medical specialist has diagnosed life threatening circumstances. However a second opinion that is a bit more optimistic simply decreases the perceived odds of death somewhat â€“ the dire initial prediction remains.
Leading world climate experts offer the expert diagnosis that the World faces a life-threatening Climate Emergency requiring urgent action to stop carbon pollution and indeed to reduce existing atmosphere greenhouse gas (GHG) pollution.
Below are about 2 dozen recent, Web-documented, expert statements from outstanding, world-leading climate change experts, other eminent scientific experts and top scientific organizations with expertise to make authoritative comments about the Climate Emergency and related matters.
These 2 dozen statements can be regarded as expert specialist diagnoses on the environmental health of the Planet's biosphere. We can seek expert second opinions by all means but these statements represent dire warnings that cannot be ignored.

Loss and degradation of remaining natural habitats has continued largely unabated. However, evidence has been accumulating that such systems generate marked economic benefits, which the available data suggest exceed those obtained from continued habitat conversion. We estimate that the overall benefit:cost ratio of an effective global program for the conservation of remaining wild nature is at least 100:1.â€

Dr Gideon Polya published some 130 works in a 4 decade scientific career, most recently a huge pharmacological reference text "Biochemical Targets of Plant Bioactive Compounds" (CRC Press/Taylor & Francis, New York & London, 2003). He has just published â€œBody Count. Global avoidable mortality since 1950â€ (G.M. Polya, Melbourne, 2007: http://mwcnews.net and http://globalbodycount.blogspot.com);
see also his contribution â€œAustralian complicity in Iraq mass mortalityâ€ in â€œLies, Deep Fries & Statisticsâ€ (edited by Robyn Williams, ABC Books, Sydney, 2007). He is currently preparing a revised and updated version of his 1998 book â€œJane Austen and the Black Hole of British Historyâ€ as biofuel-, globalization- and climate-driven global food price increases threaten a possibly 100-fold greater famine catastrophe than the man-made famine in British-ruled India that killed 6-7 million Indians in the "forgotten" World War 2 Bengal Famine (see recent BBC broadcast involving Dr Polya, Economics Nobel Laureate Professor Amartya Sen and others).
