Inquiry Launched Into Global Temperature Data Integrity

chartThe London-based think-tank the Global Warming Policy Foundation is today launching a major inquiry into the integrity of the official global surface temperature records. Questions have been raised about the reliability of the surface temperature data and the extent to which apparent warming trends may be artefacts of adjustments made after the data are collected. The inquiry will review the technical challenges in accurately measuring surface temperature, and will assess the extent of adjustments to the data, their integrity and whether they tend to increase or decrease the warming trend. —Global Warming Policy Foundation, 26 April 2015

Climatologists have long been aware of the poor state of global surface temperature records and considerable effort has been put into adjusting the raw data to correct known errors and biases. The global surface temperature records have been the subject of considerable and ongoing controversy. In order to try to provide some clarity on the scientific issues, the Global Warming Policy Foundation has invited a panel of experts to investigate and report on these controversies. The International Temperature Data Review Project

Many people have found the extent of adjustments to the data surprising. While we believe that the 20th century warming is real, we are concerned by claims that the actual trend is different from ‚Äì or less certain than ‚Äì has been suggested. We hope to perform a valuable public service by getting everything out into the open. The team approaches the subject as open-minded scientists ‚Äì we intend to let the science do the talking. Our goal is to help the public understand the challenges in assembling climate data sets, the influence of adjustments and modifications to the data, and whether they are justifiable or not. –Terence Kealey, Chairman of the International Temperature Data Review Project, 26 April 2015

The Global Warming Policy Foundation (GWPF) has enlisted an international team of five distinguished scientists to carry out a full inquiry into just how far these manipulations of the data may have distorted our picture of what is really happening to global temperatures. Their inquiry’s central aim will be to establish a comprehensive view of just how far the original data has been “adjusted” by the three main surface records: those published by the Goddard Institute for Space Studies (Giss), the US National Climate Data Center and Hadcrut, that compiled by the East Anglia Climatic Research Unit (Cru), in conjunction with the UK Met Office’s Hadley Centre for Climate Prediction. All of them are run by committed believers in man-made global warming. –Christopher Booker, The Sunday Telegraph, 26 April 2015

Panel member Professor William van Wijngaarden, a physicist and climate expert from York University in Toronto, said he had been concerned about the records’ quality for many years, after noticing that when you examined an individual station ‘you’ll see a sudden jump’. Such jumps, he said, were not natural, but the product of adjustments.  ‘Sometimes you get “corrected” data without knowing exactly how it has been changed. I’m a scientist. I’m not going into this with any preconceptions. But if some of the corrections have not been properly made, then we’ll find out. We want to see all the actual station data.’ –David Rose, Mail on Sunday, 26 April 2015
