The dramatic drop in water levels in the Kinneret Lake (Sea of Galilee) during the past years is evaluated. Recently published measurements of temperature, precipitation and other hydrological data support the position that climate change is driving the contraction of this iconic water resource. The article presents a range of evidence confirming long-term shifts in the hydrological dynamics of the watershed and details the associated ecological implications. In response to these trends, Israel's government has decided to build a desalination plant along the Northern Mediterranean shoreline that will provide water to replenish the depleted water levels in lake. Given the likelihood of continued global warming expediting increased evaporation and reduced precipitation, such climate adaptation policies constitute prudent public policy. (C) 2019 Elsevier B.V.
