In an authoritative report due out Monday a United Nations climate panel for the first time is connecting hotter global temperatures to hotter global tempers. Top scientists are saying that climate change will complicate and worsen existing global security problems, such as civil wars, strife between nations and refugees.
They're not saying it will cause violence, but will be an added factor making things even more dangerous. Fights over resources, like water and energy, hunger and extreme weather will all go into the mix to destabilize the world a bit more, says the report by the Nobel Peace Prize-winning Intergovernmental Panel on Climate Change. The summary of the report is being finalized this weekend by the panel in Yokohama.
That's a big change from seven years ago, the last time the IPCC addressed how warming affected Earth, said report lead author Chris Field of the Carnegie Institution of Science in California. The summary that political leaders read in early 2007 didn't mention security issues will, he said, because of advances in research.
"There's enough smoke there that we really need to pay attention to this," said Ohio University security and environment professor Geoff Dabelko, one of the lead authors of the report's chapter on security and climate change.
For the past seven years, research in social science has found more links between climate and conflict, study authors say, with the full report referencing hundreds of studies on climate change and conflict.
