Global Warming Impact Like 'Nuclear War'

London - Climate change could have global security implications on a par with nuclear war unless urgent action is taken, a report said on Wednesday.

The International Institute for Strategic Studies (IISS) security think-tank said global warming would hit crop yields and water availability everywhere, causing great human suffering and leading to regional strife.

While everyone had now started to recognize the threat posed by climate change, no one was taking effective leadership to tackle it and no one could tell precisely when and where it would hit hardest, it added.
