Decreased Habitat Availability and Species Die-Off
Plant and animal distributions reflect the regional climates to which they are adapted. Although species attempt to migrate in response to climate change, manmade obstacles or natural barriers such as coastlines and mountain ranges may block their paths. As isotherms move up the mountainside and poleward, the climate zone in which a given species can survive follows suit. Mountain-restricted and polar-restricted species are particularly vulnerable to climate disruption.
