Foreign and Commonwealth office, Chile is the planet's ninth most vulnerable country to climate change. This office adds, "glacial melt, shifts in rainfall patterns, expanding deserts, and greater frequency in El Niño will have an impact on water supply." Much of Chile is dominated by the Andes Mountain range and many high altitude glaciers. With rising temperatures, the IPCC warns of increased melting for many of these glaciers, with some of them disappearing as early as 2020–2030. The Third Assessment Report from the IPCC indicate a critical situation for glaciers in neighboring countries such as Bolivia and Peru. The IPCC report goes on to say that glaciers in Chile are drastically reducing their volume at an increasing rate and that changes in temperature and humidity are the primary cause. In an article from Science Daily in March 2008, the news agency reports that, "if the inter-tropical glaciers of Chile, Argentina, and Colombia disappear, water availability and hydropower generation will be affected." Of the thirty test glaciers monitored in the Andes by the World Glacier Monitoring Service (WGMS) only Chile's Echaurren Norte glacier thickened between 2005 and 2006. Offnews, a sustainable development news forum from Buenos Aires, has aggregated climate change reports and predictions from the IPCC, the World Economic Forum, the UN Economic Commission for Latin America and the Caribbean, the University of Chile, and the Chilean government. Projections in the reporting of Offnews indicate that most of Chile will see a sharp reduction in rainfall. The one exception to reduced rainfall is in northern Atacama desert where increased rainfall is projected. Aquatic ecosystems The 1981 Water Code did not account for environmental issues such as ecological flows for rivers and lakes and ambient water quality, however, the 2005 reform began to address minimum flows to protect aquatic species. It is not clear that lower flows in rivers adversely affect populations of aquatic species, but the Organisation for Economic Co-operation and Development (OECD) has analyzed the status of species in Chile and report that 41 of 44 vertebrate freshwater species are encountering conservation problems. Possible reasons include low environmental flows, climate change impacts, and mining effluents, but direct links have not been established. There are seven UNESCO biosphere reserves, nine Ramsar (convention on wetlands) sites, and three World Heritage Sites in a network of protected areas in Chile.
