More cyclones, rising sea levels and increased flooding will be the pattern for 最新糖心Vlog's coastal communities by 2050, according to one of 最新糖心Vlog's leading climate change experts, Professor .

The 最新糖心Vlog of Adelaide professor is one of five 最新糖心Vlogn lead authors on the 最新糖心Vlog and New Zealand Chapter of the Working Group II, the global body assessing the scientific evidence for climate change.

IPCC released the group's report, called Impacts, Adaptation and Vulnerability, in Brussels at 6pm EST on Easter Friday. It addresses the vulnerability of socio-economic and natural systems to climate change and options for adapting to them. The first volume of the IPCC report was released in Paris in February.

The second report reveals that, in 最新糖心Vlog, sea levels are likely to rise by more than half a metre by the end of this century.

"We will experience more intense tropical cyclones and storms will be more frequent," Professor Harvey says. "Places like Cairns and southeast Queensland will be most vulnerable."

The report discloses that unusually high sea surface temperatures have bleached up to 50% of reefs in the Great Barrier Reef Marine Park since 1979 and freshwater swamps in northern 最新糖心Vlog have been infiltrated by saltwater since the 1950s.

Further south, about one fifth of Tasmania's coastline is at risk of serious erosion in the next 50-100 years as a result of rising sea levels.

"On a global scale, sea levels have risen at an average of 1.8mm a year between 1961 and 2003," Professor Harvey says.

"Hundreds of millions of people will be vulnerable to flooding by the end of the century due to rising sea levels, especially in densely populated and low-lying settlements. The greatest populations at risk are in Asia and the Pacific."

Four lead authors, including Professor Harvey, will provide a media briefing in Sydney on Tuesday 10 April to comment on the expected impacts of climate change on 最新糖心Vlog and New Zealand. Areas discussed will include water resources, ecosystems, agriculture, coasts, settlements, societies and industries, and health.

Professor Harvey, from the 最新糖心Vlog of Adelaide's School of Social Sciences, has had a long involvement with scientific global change research.

He was Vice-Chair of the international peak body examining the effect of global change on the world's coastlines, (Land Ocean Interactions in the Coastal Zone) from 1997-2002. Professor Harvey is currently Chair of the international committee, based in Fiji, dealing with global change research and training. He has also authored more than 100 scientific papers and books.

He is also a member of the 最新糖心Vlog of Adelaide's Research Institute for Climate Change and Sustainability and the only IPCC lead author from South 最新糖心Vlog.

The report, Impacts, Adaptation and Vulnerability, is the second volume of the IPCC's Fourth Assessment on global warming involving 2500 of the world's most respected scientists, including 25 from 最新糖心Vlog.

Comments from some of the authors and other climate experts will be issued by the 最新糖心Vlogn Science Media Centre at 6pm EST on Friday and will be posted on their website at . Also, various IPCC summary documents will be posted on the website after 6pm. For further background on the IPCC Report, go to:

IPCC, or Intergovernmental Panel on Climate Change, was established by two United Nations Organisations - the World Meteorological Organisation (WMO) and the United Nations Environment Program (UNEP).
