A review on impact of climate change on evapotranspiration

Author(s):

Abstract:
Climate change is expected to intensify the hydrological cycle and to alter evapotranspiration (Huntington, 2006), with implications for ecosystem services and feedback to regional and global climate. Evapotranspiration changes may already be under way, but direct observational constraints are lacking at the global scale. Until such evidence is available, changes in the water cycle on land a key diagnostic criterion of the effects of climate change and variability remain uncertain. Land evapotranspiration (ET0) is a central process in the climate system and a nexus of the water, energy and carbon cycles Acceleration or intensification of the hydrological cycle with global warming is a long-standing paradigm in climate research (Huntington, 2006). A global network (FLUXNET) of continuous in situ measurements of land–atmosphere exchanges, including of water vapour, has been established over the last decade. The recent climatologically studies found that the global surface air temperature increased by 0.76 °C from year 1850 to year 2005. Moreover, the linear warming trend over the last 50 years is recorded by 0.13 °C per decade (IPCC, 2007). Now a days many researchers are addressing the impact of climate change on status of evapotranspiration in relation to increase in atmospheric temperature, vapour pressure deficit, precipitation and wind speed (Harmsen et al., 2009) [5].
