Water resources management in Chile
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.
Climate of Chile
On a synoptic scale, the most important factors that control the climate in Chile are the Pacific Anticyclone, the southern circumpolar low pressure area, the cold Humboldt current, the Chilean Coast Range and the Andes Mountains. Despite Chile's narrowness, some interior regions may experience wide temperature oscillations and cities such as San Pedro de Atacama, may even experience a continental climate. In the extreme northeast and southeast the border of Chile extends beyond the Andes into the Altiplano and the Patagonian plains, giving these regions climate patterns similar to those seen in Bolivia and Argentina respectively.
