U.N. Climate Panel issues dire warning of threat to global food supply, calls for action & adaption

The United Nations Intergovernmental Panel on Climate Change has issued its most dire warning yet about how greenhouse gases have driven up global temperatures and extreme weather, while threatening sources of food and water. "Throughout the 21st century, climate-change impacts are projected to slow down economic growth, make poverty reduction more difficult, further erode food security, and prolong existing and create new poverty traps, the latter particularly in urban areas and emerging hot spots of hunger," the report says.
