¥Higher
temperatures are moving rapidly toward the poles
¥Can
species adapt/move quickly enough to avoid
extinction?
¥Study
of 1,700 species found poleward migration of 6 km/decade and vertical migration in alpine regions of 6 m/decade in past 50 years
¥These
are within a factor of 2 of the surface isotherm migration in the Figure
