Climate has been a major driver of armed conflict in Africa, research shows - and future warming is likely to increase the number of deaths from war.US researchers found that across the continent, conflict was about 50% more likely in unusually warm . Writing in Proceedings of the National Academy of Sciences they suggest strife arises when the food supply is scarce in warm conditions. Warm years increased the likelihood of conflict by about 50% - and food seems to be the reason why.
"Studies show that crop yields in the region are really sensitive to small shifts in temperature, even of half a degree Celsius or so," research leader Marshall Burke, from the University of California at Berkeley, told BBC "If the sub-Saharan climate continues to warm and little is done to help its countries better adapt to high temperatures, the human costs are likely to be staggering."
If temperatures rise across the continent as computer models project, future conflicts are likely to become more common.And it will take a lot more than more money and the added investment offered up as solutions to avoid those future wars .
Commentary and analysis to persuade people to become socialist and to act for themselves, organizing democratically and without leaders, to bring about a world of common ownership and free access. We are solely concerned with building a movement of socialists for socialism. We are not reformists with a programme of policies to patch up capitalism.
