Abstract
Differences in energy exchange among major biomes affect regional climate sufficiently to warrant inclusion in regional and global climate models [Shukla, 1990 #685; Bonan, 1992 #1283]. However, arctic vegetation is considered sufficiently uniform that only a single arctic land-surface type is used in most climate models [Bonan, 1995 #1887; Lynch, 1995 #2322]. Here we show that arctic ecosystems differ sufficiently in summer energy partitioning that plausible future changes in arctic vegetation could significantly affect arctic and boreal climates.
