Humanity must change to avert disaster: Al Gore

Humanity must change how it lives, travels and grows food in order to avert global warming catastrophe, Nobel laureate Al Gore said at the Paris climate summit yesterday.

He pointed to a string of extreme droughts, record-breaking downpours and high tides, along with melting Arctic ice as evidence of climate change.

The scientific community is "virtually unanimous" on the existence of man-made climate change and the evidence is "just as clear as it is for the existence of gravity."
