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.
Hiking in Chile
The Sendero de Chile trail runs 18 km from the Serrano Conaf lodge up along the western side of Lake Pehoé, via Las Carretas campsite and Mirador Pehoe lookout, ending at the Pehoe Conaf lodge, and offers views of the Cordillera del Paine, Grey Glacier and Lake Pehoé. 
There are several other well-known hiking trails within Torres del Paine National Park, including the “W”, which leads in and out of the valleys on the south side of the Paine massif, and the “Full Circuit”, which continues on around the less-visited north side of the massif.
