David Attenborough joined scientists yesterday to warn that carbon dioxide in the atmosphere is already above the level which condemns coral reefs to extinction in the future, with catastrophic effects for the oceans and the people who depend upon them.
Carbon dioxide in the atmosphere is around 387ppm today. Environmentalists say that the world could be heading for 550ppm or even 650ppm.
"When we get up to and above 450ppm, that really means we're into the realms of catastrophic destruction of coral reefs and we'll be moving into a planetary-wide global extinction," said Rogers.
"The only way to get to 350ppm or below is not only to have major cuts in CO2 emissions but also to draw CO2 out of the atmosphere through measures such as geo-engineering."
