I will leave it to skeptical climatologists to make systematic comments on the report below but a few comments from me anyway: The peer-reviewed papers concerned almost certainly are based on data from some years back — and there have been a lot of changes in recent years that make the conclusions laughable. Take the claim that the Earth is continuing to warm at the rate of about 0.16C a decade. Who knew? That’s nowhere in the data for the last 10 years. And even Phil Jones of CRU admits that there has been no statistically significant warming since 1995. “Not statistically significant” means “so small that it could have been caused by chance alone”.
On a more personal note, the claim that more rain is falling in high and low latitudes and less in tropical and sub-tropical regions is really a laugh. I live in the sub-tropics and we are having huge amounts of rain — with most dams in the region overflowing and rarely seen high levels in those that are not overflowing: “Dams are holding the most water ever recorded in Queensland’s history”. To sum up the report below in one word: Crap — JR
EVIDENCE that human activity is causing global warming is much stronger than previously stated and is found in all parts of the world, according to a study that attempts to refute claims from sceptics. The “fingerprints” of human influence on the climate can be detected not just in rising temperatures but in the saltiness of the oceans, rising humidity, changes in rainfall and the shrinking of Arctic Sea ice at the rate of 600,000sq km a decade.
The study, by senior scientists from Britain’s Met Office Hadley Centre, the University of Edinburgh, Melbourne University and Victoria University in Canada, concluded that there was an “increasingly remote possibility” that the sceptics were right that human activities were having no discernible impact. There was a less than 5 per cent likelihood that natural variations in climate were responsible for the changes.
The study said that the Intergovernmental Panel on Climate Change (IPCC) had understated mankind’s overall contribution to climate change. The IPCC had said in 2007 that there was no evidence of warming in the Antarctic. However, the panel said the latest observations showed that man-made emissions were having an impact on even the remotest continent.
The panel assessed more than 100 recent peer-reviewed scientific papers and found that the overwhelming majority had detected clear evidence of human influence on the climate. Peter Stott, head of climate monitoring and attribution at the Met Office, who led the study, said: “This wealth of evidence we have now shows there is an increasingly remote possibility of climate change being dominated by natural factors rather than human factors.”
However, a section of the study that said changes in hurricane activity were poorly understood is likely to be seized on by sceptics, who argue that disasters such as Hurricane Katrina have been falsely blamed on man-made global warming.
Publication of the research in the journal Wiley Interdisciplinary Reviews: Climate Change comes as two inquiries are being held into accusations, based on leaked e-mails, that scientists at Britain’s University of East Anglia mani- pulated and suppressed climate data. The study found that since 1980, the average global temperature had increased by about 0.5C (0.9F) and that the Earth was continuing to warm at the rate of about 0.16C a decade.
This trend is reflected in measurements from the oceans. Warmer temperatures had led to more evaporation from the surface, most noticeably in the sub-tropical Atlantic, said Dr Stott. As a result, the sea was getting saltier. Evaporation in turn affected humidity and rainfall. The atmosphere was getting more humid, as climate models had predicted, and amplifying the water cycle. This meant more rain was falling in high and low latitudes and less in tropical and sub-tropical regions.
