REUTERS/Denis Balibouse/PARIS, Nov 3 (Reuters) - Some of the world's most famous glaciers, including in the Dolomites in Italy, the Yosemite and Yellowstone parks in the United States and Mount Kilimanjaro in Tanzania will disappear by 2050 due to global warming, whatever the temperature rise scenario, according to a UNESCO report. The United Nations cultural agency UNESCO monitors some 18,600 glaciers across 50 of its World Heritage sites and said that a third of those are set to disappear by 2050. While the rest can be saved by keeping global temperature rise below 1.5 degree Celsius (2.7 Fahrenheit) relative to pre-industrial levels, in a business-as-usual emissions scenario, about 50% of these World Heritage glaciers could almost entirely disappear by 2100. World Heritage glaciers as defined by UNESCO represent about 10 percent of the world's glacier areas and include some of the world's best-known glaciers, whose loss is highly visible as they are focal points for global tourism. Carvalho said that the single most important protective measure to prevent major glacier retreat worldwide would be to drastically reduce carbon emissions.
