Chile
The diverse climate of Chile ranges from the world's driest desert in the north—the Atacama Desert—through a Mediterranean climate in the center, humid subtropical in Easter Island, to an oceanic climate, including alpine tundra and glaciers in the east and south. According to the Köppen system, Chile within its borders hosts at least ten major climatic subtypes. There are four seasons in most of the country: summer (December to February), autumn (March to May), winter (June to August), and spring (September to November).
The flora and fauna of Chile are characterized by a high degree of endemism, due to its particular geography. In continental Chile, the Atacama Desert in the north and the Andes mountains to the east are barriers that have led to the isolation of flora and fauna. Add to that the enormous length of Chile (over ) and this results in a wide range of climates and environments that can be divided into three general zones: the desert provinces of the north, central Chile, and the humid regions of the south.
List of glaciers
The glaciers of Chile cover 2.7% (20,188 km) of the land area of the country, excluding Antártica Chilena, and have a considerable impact on its landscape and water supply. By surface 80% of South America’s glaciers lie in Chile. Glaciers develop in the Andes of Chile from 27˚S southwards and in a very few places north of 18°30'S in the extreme north of the country: in between they are absent because of extreme aridity, though rock glaciers formed from permafrost are common. The largest glaciers of Chile are the Northern and Southern Patagonian Ice Fields. From a latitude of 47° S and south some glaciers reach sea level.
