“We are basically looking now at a future climate that is beyond anything that we’ve considered seriously in climate policy,” he said.
Prof Field said the 2007 report, which predicted temperature rises between 1.1C and 6.4C over the next century, seriously underestimated the scale of the problem.
He said the increases in carbon dioxide have been caused, principally, by the burning of coal for electric power in India and China.
Prof Field said the impact on temperatures is as yet unknown, but warming is likely to accelerate at a much faster pace and cause more environmental damage than had been predicted.
As malthus once said, self-limiting. Unless we do something really stupid like destabilizing sedimentary methane.
