Australia and New Zealand Warned by United Nations

Australia has warned that it will have to switch off the water supply to the continent's food bowl unless heavy rains break an epic drought - heralding what could be the first climate change-driven disaster to strike a developed nation.

Australia's epic drought: The situation is grim - Independent Online Edition > Australasia

Excerpts from United Nations' Intergovernmental Panel on Climate Change (IPCC) report on the threat of global warming to Australia and New Zealand:

"As a result of reduced precipitation and increased evaporation, water security problems are projected to intensify by 2030 in south and east Australia and, in New Zealand, in Northland and eastern regions."

"Significant loss of biodiversity is projected to occur by 2020 in some ecologically rich sites, including the Great Barrier Reef and Queensland's tropics. Other sites at risk include the Kakadu wetlands ... and the alpine areas of both countries."

"Ongoing coastal development and population growth in areas such as Cairns and south-east Queensland (Australia) and Northland to Bay of Plenty (New Zealand) are projected to exacerbate risks from sea-level rise and increases in the severity and frequency of storms and coastal flooding by 2050."

"Production from agriculture and forestry by 2030 is projected to decline over much of southern and eastern Australia, and over parts of eastern New Zealand, due to increases in droughts and fires."

"The region has substantial adaptive capacity due to well-developed economies and scientific and technical capabilities, but there are considerable constraints to implementation ... Natural systems have limited adaptive capacity."
