Major study questions quality of global temperature data in climate change debate

The 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.

An internaticlickonal team of eminent climatologists, physicists and statisticians has been assembled under the chairmanship of Professor Terence Kealey, the former vice-chancellor of the University of Buckingham.

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.

Launching the inquiry, Professor Kealey said:

“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 – or less certain than – has been suggested. We hope to perform a valuable public service by getting everything out into the open.”

To coincide with the inquiry launch Professor Kealey has issued a call for evidence:

“We hope that people who are concerned with the integrity of climate science, from all sides of the debate, will help us to get to the bottom of these questions by telling us what they know about the temperature records and the adjustments made to them. The team approaches the subject as open-minded scientists – 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.”

All submissions will be published.
