Poznan: Aid agencies say overwhelmed by rising climate disasters

"Floods, droughts, storms do not have to end in disaster, they don't have to kill, people don't have to die. They die because they are not prepared" Kasidis Rochanakorn, director of the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) in Geneva, told journalists at the UN Climate Change talks on Wednesday in Poznan.
