Science plays a key role in finding new ways to combat climate change, UN Secretary General Ban Ki-moon said on Saturday, stressing that governments must use scientific data to mobilise resources and take action against the global threat.

 

"The reason climate change has risen on the global agenda is because the facts don't lie. Our world is warming, and our greenhouse gas emissions are a significant cause," Ban told members of the National Centre for Atmospheric Research in Boulder, in the US state of Colorado.
