Professors Johan Rockstrom of the Potsdam Institute for Climate Impact Research and David King, chair of the Centre for Climate Repair at the University of Cambridge, have said that failure to limit the temperature rise could lead to the collapse of life on the planet.

Highlights

• "There's one conclusion without any uncertainty whatsoever, and that is that a 2.5C global mean surface temperature rise is a disaster." He added, "1.5C is not a target. I call it a physical limit."

• "It's something that humanity has absolutely no evidence that we can cope with. It would actually exceed the warmest temperature on Earth over the past four million years."

• The aforementioned reports and testimonies have made it quite clear that humans can no longer afford to turn a blind eye to their environment, and urgent actions at a global level are needed to address and restrict the rise in temperature.
