Established pro-climate science models had recently been making "hindcasts" – backward projections based on climate simulations and tailored to actual temperatures. The evidence shows the models collapse when they try to forecast the future (see larger model graph here).

UK Media Attacked for
Revealing False Climate Science

The London Daily Mail
The official UK watchdog that advises the Government on greenhouse gas emissions targets has launched an astonishing attack on The Mail on Sunday – for accurately reporting that alarming predictions of global warming are wrong.

London Daily Mail disclosed that although highly influential computer models are still estimating huge rises in world temperatures, there has been no statistically significant increase for more than 16 years.

Despite our revelation earlier this month, backed up by a scientifically researched graph, the Committee on Climate Change still clings to flawed predictions.

Leading the attack is committee member Sir Brian Hoskins, who is also director of the Grantham Institute for Climate Change at Imperial College, London. In a blog on the Committee on Climate Change's website, Sir Brian insisted: "The scientific basis for significant long-term climate risks remains robust, despite the points raised...Early and deep cuts in emissions are still required."

He also claimed our report "misunderstood" the value of computer models. Yet in an interview three years ago, Sir Brian conceded that when he started out as a climate scientist, the models were "pretty lousy, and they're still pretty lousy, really."

Our graph earlier this month was reproduced from a version first drawn by Dr Ed Hawkins, of the National Centre for Atmospheric Science. Last week it was reprinted as part of a four-page report in The Economist.

The accuracy of computer forecasts is vital because they influence politicians and their key environmental advisers on how urgently to act on climate change – and how many billions of pounds they take from the taxpayer in "green" levies.

The Committee on Climate Change claims such forecasts must be right because world temperatures have previously matched computer models' "outputs" for most of the past 60 years. Yet as this newspaper pointed out, for almost all of that 60-year period the models were not making predictions – because they did not yet exist.

Instead, the models had recently been making "hindcasts" – backward projections based on climate simulations and tailored to actual temperatures. The evidence shows the models collapse when they try to forecast the future.

Author Andrew Montford, who runs the widely read Bishop Hill climate blog, leapt to The Mail on Sunday's defense and said Sir Brian's reliance on "hindcasts" was "crazy, crazy stuff."

David Whitehouse, of the Global Warming Policy Foundation, said the graph showed models were so unreliable that "if this kind of data were from a drugs trial it would have been stopped long ago."

And last week, The Economist repeated our claims that many scientists now believe that previous estimates of "climate sensitivity" – how much the world will warm each time the level of carbon dioxide doubles – are far too high.

In a key 2007 report, the UN Intergovernmental Panel on Climate Change suggested this was most likely to be about 3C, with 4.5C considered "likely." However, recent research suggests the true figure is much lower – between 1.5C and 2C – giving the world many more decades to avoid disaster through effective new technologies.

The Committee on Climate Change, established by the 2008 Climate Change Act, advises the Government on setting "carbon budgets" and CO2 emissions cuts.
