We thank Stephen Halpern and Anna Reisman for their interest in our abstract1 on seawater intrusion into the coastal aquifer in the Gaza Strip. The main objective of our research is to investigate the effects of climate change scenarios on seawater intrusion in Gaza's coastal aquifer. Because climate change has long-term effects, the current sea intrusion in Gaza's coastal aquifer is due to other factors. A key factor behind the occurrence of the seawater intrusion in Gaza's coastal aquifer is over-pumping from the aquifer.
