Climate Change 2001: The Scientific Basis
Briffa et al. series for IPCC figure
“On 22 September 1999, Met Office scientist Chris Folland, an IPCC lead author, alerted key researchers that a diagram of temperature change over the past thousand years “is a clear favourite for the policy makers’ summary”. But there were two competing graphs – Mann’s hockey stick and another, by Phil Jones, Keith Briffa and others, which sought to ascertain temperatures over the past millennium using, among other things, tree rings, ice cores and coral. Mann’s graph was clearly the more compelling image of man-made climate change. Jones and Briffa’s “dilutes the message rather significantly,” said Folland. “We want the truth. Mike [Mann] thinks it lies nearer his result.” But Briffa did not. Three hours later, he sent a long and passionate email. “It should not be taken as read that Mike’s series is THE CORRECT ONE,” he warned. “I know there is pressure to present a nice tidy story as regards ‘apparent unprecedented warming in a thousand years or more in the proxy data’, but in reality the situation is not quite so simple… For the record, I believe that the recent warmth was probably matched about 1,000 years ago.“

“An international team of specialists has concluded from eight indexes of climate that there is no end in sight to the cooling trend of the last 30 years, at least in the Northern Hemisphere.
Data from the Southern Hemisphere, particularly south of latitude 30 south, are so meager that reliable conclusions are not possible, the report says. “

Stockhpld, Sweden, Dec. 16—All‘the glaciers in Eastern Greenland are rapidly melting, declared Prof. Hans Ahlmann, Swedish geologist, in a report to the Geographical Society here on his recent expedition to the Arctic sub-continent.
“Everything points to the fact that the climate in that region has been growing Warmer during recent years, ” the professor said.
“It may without exaggeration be said that the glaciers, like those in ‘Norway, face the possibility of a catastrophic collapse.”

“Scientists have confirmed the fact that the Arctic regions around Spitzbergen are warming up at the rate of approximately one degree in every two years. Since 1910, when observations first started in those regions, the cumulative rise of winter temperature has amounted to nearly 16 degrees. Such a profound change has been at-tended by new and strange phenomena over the whole area surrounding the Polar basin. It has been found that the Polar icefields are receding gradually northwards, while soil which at one time remained solidly frozen throughout the year now undergoes a partial thaw during the Arctic summers. In the Barents Sea area where, during earlier observations, only small patches became free from ice, large spaces of open water now occur at frequent intervals.”
