All of a sudden, it’s OK to question the conclusions of climate alarmists
“The temperature records cannot be relied on as indicators of global change,” said John Christy, professor of atmospheric science at the University of Alabama in Huntsville, a former lead author on the IPCC.
These stations, they believe, have been seriously compromised by factors such as urbanisation, changes in land use and, in many cases, being moved from site to site.
Christy has published research papers looking at these effects in three different regions: east Africa, and the American states of California and Alabama.
“The story is the same for each one,” he said. “The popular data sets show a lot of warming but the apparent temperature rise was actually caused by local factors affecting the weather stations, such as land development.”
So are we warming at all? Besides Phil Jones admitting that there’s no statistically significant evidence for it since 1995, the article above casts more doubt:
Terry Mills, professor of applied statistics and econometrics at Loughborough University, looked at the same data as the IPCC. He found that the warming trend it reported over the past 30 years or so was just as likely to be due to random fluctuations as to the impacts of greenhouse gases. Mills’s findings are to be published in Climatic Change, an environmental journal.
“The earth has gone through warming spells like these at least twice before in the last 1,000 years,” he said.
Naturally, the usual suspects are sticking to the “global warming is definite” position. The article quotes Kevin Trenberth, who was involved in the Climategate scandal, as one of them. Another is the head of the Met Office that seems to be hellbent on working warming into their weather predictions.
We seem to have passed a tipping point in the last few weeks. At the very least we’ve moved from global warming/climate change being discussed as a quasi-religious cause being crammed down everyone’s throats to having some genuine debate about the data and the science.
Not to say there are not holdouts; some people won’t give up their religion easily. Most American legacy media outlets have been silent, for example, and the comments on the article above still contain the usual ears-in-fingers-I-can’t-hear-you entries. However, if the best the Daily Mail can come up with to defend global warming are those already caught up in controversies of their own, that in itself is an indicator of just how much the debate has changed.
