Climate change caused by humans will result in food shortages, mass extinctions and flooding, warns the world body of climate experts, the Intergovernmental Panel on Climate Change (IPCC), in its most comprehensive report yet.

The report, signed in Bonn today, says the science is now 95 per cent conclusive, that today’s climate change is unprecedented, and warns that the world must act, together and immediately, on adaptation and mitigation. It says some changes are already inevitable and the risk of not acting is extreme: “Without additional mitigation efforts beyond those in place today, and even with adaptation, warming by the end of the 21st century will lead to high to very high risk of severe, widespread and irreversible impacts, globally.”

F&O provides a brief  introduction and summary, and verbatim excerpts from the IPCC’s latest, sobering, report and warning. … read (free*): Verbatim: Climate change to cause food shortages, mass extinctions, flooding.
