Mountains and global warming







Mountains cover approximately 25 percent of earth's surface .Changes in global climate affect mountain habitats. Climate change will affect mountain and lowland ecosystems, distribution of water and increase the number of forest fires.

Plants and animals have limited space available for new habitat as they move higher on the mountains in order to adapt to long-term changes in regional climate.

Changes in climate will also affect the depth of the mountains and glaciers. Any changes in their seasonal melting can have powerful impacts on areas that rely on freshwater runoff from mountains. Rising temperature may cause snow to melt earlier and faster in the spring and change the timing and distribution of runoff. These changes could affect the availability of freshwater for natural systems and human uses.
