The velocity of temperature change globally.Differentemissionsscenarios
Land-cover change results in formidable barriers to species movement. Thus, keeping pace with climate change is more feasible in protected areas where landscapes may be less fragmented
Organ Pipe National Monument
Climate residence time (yr) in protected areas.Residence time =Diameter of area/velocity (km/km yr -1)
Residence time =Diameter of area/velocity (km/km yr -1)= time for currentclimate to cross area
Ninth highest residence time
Velocities and residence times for climate and not species29% of the globe with velocities > 1
km/yearTrees were thought to have moved about 1
km/year after the last glacial maximumMost plants and animals move much slower
than 1 km/yearWe understand very little…
