What can’t climate change do?
Did climate change help spark the Syrian war?
A new study says a record drought that ravaged Syria in 2006-2010 was likely stoked by ongoing manmade climate change, and that the drought may have helped propel the 2011 Syrian uprising. Researchers say the drought, the worst ever recorded in the region, destroyed agriculture in the breadbasket region of northern Syria, driving dispossessed farmers to cities, where poverty, government mismanagement and other factors created unrest that exploded in spring 2011. The conflict has since evolved into a complex multinational war that has killed at least 200,000 people and displaced millions. The study appears today in the leading journal Proceedings of the National Academy of Sciences.
“We’re not saying the drought caused the war,” said Richard Seager, a climate scientist at Columbia University’s Lamont-Doherty Earth Observatory who coauthored the study. “We’re saying that added to all the other stressors, it helped kick things over the threshold into open conflict. And a drought of that severity was made much more likely by the ongoing human-driven drying of that region.”
A growing body of research suggests that extreme weather, including high temperatures and droughts, increases the chances of violence, from individual attacks to full-scale wars. Some researchers project that manmade global warming will heighten future conflicts, or argue that it may already be doing so. And recent journalistic accounts and other reports have linked warfare in Syria, Iraq and elsewhere in part to environmental issues, especially lack of water. The new study, combining climate, social and economic data, is perhaps the first to look closely and quantitatively at these questions in relation to a current war.
The recent drought affected the so-called Fertile Crescent, spanning parts of Turkey and much of Syria and Iraq, where agriculture and animal herding are believed to have started some 12,000 years ago. The region has always seen natural weather swings. But using existing studies and their own research, the authors showed that since 1900, the area has undergone warming of 1 to 1.2 degrees Centigrade (about 2 degrees Fahrenheit), and about a 10 percent reduction in wet-season precipitation. They showed that the trend matches neatly with models of human-influenced global warming, and thus cannot be attributed to natural variability.
Global warming has had two effects, they say. First, it appears to have indirectly weakened wind patterns that bring rain-laden air from the Mediterranean, reducing precipitation during the usual November-April wet season. Second, higher temperatures have increased evaporation of moisture from soils during the usually hot summers, giving any dry year a one-two punch. The region saw substantial droughts in the 1950s, 1980s and 1990s. However, 2006-10 was easily the worst and longest since reliable recordkeeping began. The researchers concluded that an episode of this severity and length would have been unlikely without the long-term changes.
8 to 20 inches per year is Syria’s annual rainfall over the last 5 decades.
In CA it averages between 2.9 inches and 21 inches.
Where are our riots?
Damascus was built on an oasis.
Gee, I wonder why.
Yeah Curt climate change has no national security issues
Please email the USMC and explain to them his wrong they are in this
