The Inter Press Service has an interesting interview with James Lovelock, known for proposing the Gaia hypothesis, about everything from the IPCC to geo-engineering and climate tipping points.

Lovelock has earlier said that he believes that climate change is now irreversible. He predicts that the major part of the humans, more than six billion people, will get wiped out of the face of the earth due to wars, starvation, epidemics and chaos during the rest of the century due to the effects of a changing climate. Lovelock estimates that by year 2100 there will only be around 500 millions people left who struggles to survive on the few remaining liveable places on earth: Scandinavia, Canada and Iceland.

In the IPS interview Lovelock says he hopes that once climate disaster strikes “we will stay civilised and those in the North will give refuge to the unimaginably large numbers of climate refugees”:

“TIERRAMÉRICA: What will this new climate be like?

JL: The tropical and subtropical zones of the Earth will be too hot and dry to grow food or support human life. People will be forced to migrate towards the poles to places like Canada. There will be less than one billion people by the end of the century. My hope is that we will stay civilised and those in the North will give refuge to the unimaginably large numbers of climate refugees.”

A new scientific study from the National Oceanic and Atmospheric Administration (NOAA) in USA shows that “there’s no going back” from climate change caused by carbon dioxide. The study, led by NOAA senior scientist Susan Solomon, has reached the shocking conclusion that the effects of man-made climate change are largely irreversible for more than 1,000 years after carbon dioxide (CO2) emissions are completely stopped.

“Our study convinced us that current choices regarding carbon dioxide emissions will have legacies that will irreversibly change the planet,” said Solomon, who is based at NOAA’s Earth System Research Laboratory in Boulder, Colo.

“It has long been known that some of the carbon dioxide emitted by human activities stays in the atmosphere for thousands of years,” Solomon said. “But the new study advances the understanding of how this affects the climate system.”
