New Study Suggests Climate Change Could Be The Root Of Armed Conflicts
London UK (SPX) Jul 12, 2007 Climate change, and the resulting shortage of ecological resources, could be to blame for armed conflicts in the future, according to David Zhang from the University of Hong Kong and colleagues. Their research, which highlights how temperature fluctuations and reduced agricultural production explain warfare frequency in eastern China in the past, has been published online in Springer's journal Human Ecology. Zhang and his team looked at the impact of climate change on warfare frequency over the last millennium in eastern China. The agricultural production in the region supports the majority of the Chinese population. The authors reviewed warfare data from 899 wars in eastern China between 1000 and 1911, documented in the Tabulation of Wars in Ancient China. They cross-referenced these data with Northern Hemispheric climate series temperature data for the same period. They found that warfare frequency in eastern China, and the southern part in particular, significantly correlated with temperature oscillations. Almost all peaks of warfare and dynastic changes coincided with cold phases. Temperature fluctuations directly impact agriculture and horticulture and, in societies with limited technology such as pre-industrial China, cooling temperatures hugely impact the availability of crops and herds. In times of such ecological stress, warfare could be the ultimate means of redistributing resources, according to Zhang and his team. The authors conclude that "it was the oscillations of agricultural production brought by long-term climate change that drove China's historical war-peace cycles." They recommend that researchers consider climate change part of the equation when they consider the reasons behind wars in our history. Looking to the future and applying their findings, Zhang and colleagues suggest that shortages of essential resources, such as fresh water, agricultural land, energy sources and minerals may trigger more armed conflicts among human societies.

Western US States Swelter Under Record Heatwave
Los Angeles (AFP) Jul 06, 2007A ferocious heatwave that has gripped the western United States was expected to continue on Friday, with sizzling record temperatures forecast across the sun-baked region. Although temperatures cooled in California early Friday as a high pressure weather system lifted, excessive heat warnings remained in place across large swathes of the state and neighboring Nevada and Arizona. "The high pressure system that has been stubbornly parked over southern California is on a weakening trend, allowing temperatures to cool down to seasonable temperatures," meteorologist Jamie Meier said. |
