Recent studies report global ET increases from the early 1980s to 2009 and 2013 . Calculations informed by observations suggest that ET has increased in most regions, with statistically significant  trends of up to 10 mm yr-2 observed in large parts of North America and northern Eurasia. Larger increases in ET are also observed in several regions, including northeast Brazil, western central Africa, southern Africa, southern India, southern China, and northern Australia. Decreases of around 10 mm yr2 are reported for western Amazonia and central Africa , although not across all data sets . In estimates of past changes in long-term drying or wetting of the land surface driven by climate, uncertainties in ET observations or reconstructions make a more substantial contribution to the overall uncertainty than observed changes in precipitation . Other changes in ET are also driven strongly by land cover changes and irrigation .
