What scientists say about climate impacts

 Sea levels

Prof. JONATHAN BAMBER
“Even moderate climate warming has incredibly serious consequences for humanity, and those consequences grow exponentially as the temperature rises. The committed sea-level rise from Antarctica even at 2°C represents an existential threat to entire nation states. We’re looking at removing nations from a map of the world because they no longer exist.”

Prof. HANS JOACHIM SCHELLNHUBER
"In the long run, there is the problem of sea level rise. One degree, in the long run, translates into 15-20 meters sea level rise in equilibrium. Two degrees, the target of the European Union, means sea level rise of 30-40 meters – over maybe a thousand years. Draw a line around your coast – probably not a lot would be left."

Profs YANGYANG XU AND VEERABHADRAN RAMANATHAN
“For those among the bottom 3 billion of the world’s population who are living in coastal areas, a 1- to 2-metre rise in sea level (likely with a warming in excess of 3°C) poses existential threat if they do not relocate or migrate.”

People and displacement

Prof. KEVIN ANDERSON
“A 4°C future is incompatible with an organised global community, is likely to be beyond ‘adaptation’, is devastating to the majority of ecosystems and has a high probability of not being stable”.

Prof. JOHAN ROCKSTRĂ–M
At 4°C: “It’s difficult to see how we could accommodate eight billion people or maybe even half of that.”
