  • Leaked report reveals the world is warming at half the rate claimed by IPCC in 2007
  • Scientists accept their computers ‘may have exaggerated’

A leaked copy of the world’s most authoritative climate study reveals scientific forecasts of imminent doom were drastically wrong.

The Mail on Sunday has obtained the final draft of a report to be published later this month by the UN Intergovernmental Panel on Climate Change (IPCC), the ultimate watchdog whose massive, six-yearly ‘assessments’ are accepted by environmentalists, politicians and experts as the gospel of climate science.

They are cited worldwide to justify swingeing fossil fuel taxes and subsidies for ‘renewable’ energy.

Yet the leaked report makes the extraordinary concession that the world has been warming at only just over half the rate claimed by the IPCC in its last assessment, published in 2007.

Back then, it said that the planet was warming at a rate of 0.2C every decade – a figure it claimed was in line with the forecasts made by computer climate models.

But the new report says the true figure since 1951 has been only 0.12C per decade – a rate far below even the lowest computer prediction.

The 31-page ‘summary for policymakers’ is based on a more technical 2,000-page analysis which will be issued at the same time. It also surprisingly reveals: IPCC scientists accept their forecast computers may have exaggerated the effect of increased carbon emissions on world temperatures  – and not taken enough notice of natural variability…

…Last night Professor Judith Curry, head of climate science at Georgia Institute of Technology in Atlanta, said the leaked summary showed that ‘the science is clearly not settled, and  is in a state of flux’. She said  it therefore made no sense that the IPCC was claiming that its confidence in its forecasts and conclusions has increased…

Update: BBC Archives confirm Global Cooling as scientific ‘orthodoxy’ of the early 1970s

Who knew? In 1999, long before selling its soul to climate catastrophism, the BBC had no problem in letting its listeners know that scientists in the 1970s were convinced about Global Cooling. And that contemporary scientist-activists about Warming are just recycling arguments used agains Cooling…
