Lovelock believes that the transformation is happening far too fast for humanity to tackle, especially in a world that remains committed to economic growth and whose 6.5 billion population is predicted to reach more than 9 billion by mid-century.
For evidence, he points to Siberia where the melting of the permafrost, already widely reported in scientific literature, will enable bacteria to decompose organic matter that has accumulated in the soil over tens of millions of years – potentially releasing billions more tons of CO2 “I have just come back from Norway where the temperatures are even further above normal than Britain’s. The climate is changing every year now. Everyone can see it – as in this very warm April. By mid-century the heatwave
that killed 20,000 people in 2003 will be a cool summer by comparison.”
At first sight Lovelock’s predictions seem wildly at odds with the IPCC’s reports, but in many ways the only difference is in the vividness of the language. “The progressive acidification of oceans due to increasing atmospheric carbon dioxide is expected to have negative impacts on marine shell-forming organisms (ie corals) and their dependent species,” said the IPCC report detailing the impacts of climate change – its careful language draining the drama from a warning that vast tracts of the ocean may turn so acidic that little life will be left in them.
It added: “At lower latitudes, especially seasonally dry and tropical regions, crop productivity is projected to decrease for even small local temperature increases (1-2C), which would increase risk of hunger.” What these measured tones imply, warns Lovelock, is that millions – perhaps hundreds of millions – of people living in equatorial lands will be forced from their homes, with most of them heading northwards. “The world will face mass shortages of food and water. That will lead to wars and the effective clearance of vast areas of land as the deserts spread,” he said.
