water palestine drought israel

  • rising temperatures, spiralling population growth and inefficient irrigation are severely straining resources and threatening renewed economic and social breakdown.
  • Lebanon has the highest annual rainfall in the region, averaging 827mm compared to 630mm in Israel, 252mm in Syria and just 154mm in Iraq
  • Yet experts estimate that demand for water in Lebanon will have increased by more than 80 percent by 2025 as Lebanon’s population is expected to grow from four to 7.6 million. In the same period, as a result of climate change, average summer temperatures in the country are predicted to increase by 1.2 degrees centigrade.

  • Across areas of the northern Bekaa with better irrigation, many farmers have turned land over to growing water-thirsty but economically lucrative hashish plants – totalling some 16,000 acres of land
  • The valley is an economically underdeveloped area where more than 40 percent of residents are dependent on agriculture as their main source of living

water precipitation geoengineering climate change

shared by Benno Hansen on 09 Aug 09 - Cached
  • "if geo-engineering studies focus too heavily on warming, critical risks associated with such possible "cures" will not be evaluated appropriately"
  • climate change is about much more than changes in temperature. So using temperature alone to monitor the effects of geo-engineering could be dangerous.
  • current climate models tend to underestimate the effects on precipitation of both greenhouse gases and of volcanic eruptions

  • The article warns that geo-engineering of this type, combined with the effects of global warming could produce reductions in regional rainfall that could rival those of past major droughts, leading to winners and losers among the human population and possible conflicts over water.

  • "optimism about a geo-engineered 'easy way out' should be tempered by examination of currently observed climate changes."

      hvorfor skulle geoengineering ikke have uforudsete bivirkninger når klimaforandringerne i sig selv er en "uforudset" (overraskende stor) bivirkning ved afbrænding af fossile brændstoffer?
