Última Potential effects of climate change on the temperate zones of North and South America 97 LAUENROTH,W.K.; EPSTEIN,H.E.; PARUELO,J.M.; BURKE,I.C.; AGUIAR,M.R.; SALA,O.E.. Under current conditions, large areas of temperate western North America and temperate southern South America have arid to subhumid climates that make them vulnerable to changes as a result of human-induced climate change. Predictions of climate change from global circulation models with a doubling of present atmospheric levels of CO2 suggest large changes in mean annual temperature and small to no changes in mean annual precipitation and the proportion of precipitation received during the summer. Our objective here was to evaluate how predictions of climate change from global circulation models will influence climatic patterns and by inference the distribution of temperate zone ecosystems in North and South America. Calculations of annual water deficits... Tipo: Journal article Palavras-chave: Climate change; Temperate ecosystems; Global circulation model; CO2.
