Regional changes in ET depend on changes in both the climate and the properties of the land surface and ecosystems. The latter also responds to changes in climate and atmospheric composition. For example, a warming climate increases evaporative demand , although seasonal rainfall totals  affect the amount of soil moisture available for evaporation. Since transpiration accounts for much of the land-atmosphere water flux , vegetation changes also play a significant role in overall changes in ET.
