What I’m convinced of is that we don’t understand climate, and so that’s sort of a neutral position. I’m not saying the majority is necessarily wrong. I’m saying that they don’t understand what they’re seeing.

The most important is a claim that global warming could cut rain-fed north African crop production by up to 50% by 2020. There is however one teensy-weensy little problem. As Professor Chris Field, the lead author of the IPCC’s climate impact team has now told reporters that he can find “no evidence” to support the claim in the IPCC’s 2007 report.

In a statement released on Wednesday, the IPCC admitted that the Working Group II report, “Impacts, Adaptation and Vulnerability,” published in the IPCC’s Fourth Assessment Report (2007), contains a claim that “refers to poorly substantiated estimates. ” The statement also said “the clear and well-established standards of evidence, required by the IPCC procedure, were not applied properly.”

Environmentalist, Warming, Science, Oops, Fear, Demagoguery
James Lovelock, the maverick scientist who became a guru to the environmental movement with his “Gaia” theory of the Earth as a single organism, has admitted to being “alarmist” about climate change and says other environmental commentators, such as Al Gore, were too. Lovelock, 92, is writing a new book in which he will say climate change is still happening, but not as quickly as he once feared... In 2006, in an article in the U.K.’s Independent newspaper, he wrote that “before this century is over billions of us will die and the few breeding pairs of people that survive will be in the Arctic where the climate remains tolerable.”

First, it was a series of e-mails that led many to begin doubting the veracity of climate scientists. Then, the United Nations climate body itself had to reverse dire predictions about the melting of glaciers in the Himalayan Mountains. Other claims have raised doubts as well.

JUNEAU, Alaska (AP) — A federal wildlife biologist whose observation in 2004 of presumably drowned polar bears in the Arctic helped to galvanize the global warming movement has been placed on administrative leave and is being investigated for scientific misconduct, possibly over the veracity of that article.

WASHINGTON (AFP) – A climate change study that projected a 2.4 degree Celsius increase in temperature and massive worldwide food shortages in the next decade was seriously flawed, scientists said Wednesday.

WASHINGTON: The Earth will be 2.4 degree Celsi US warmer by 2020 if the world continues with the business-as-usual approach to climate change and India would be one of the hardest hit countries witnessing upto 30 per cent reduction in crop yields, a new study has claimed.

First it turns out that the Himalayan glaciers are not going to melt anytime soon, notwithstanding dire U.N. predictions. Next came news that an IPCC claim that global warming could destroy 40% of the Amazon was based on a report by an environmental pressure group. Other IPCC sources of scholarly note have included a mountaineering magazine and a student paper.

“‘The IPCC acknowledges in its 4th Assessment Report that ENSO conditions cannot be predicted more than about 12 months ahead, so the output of climate models that could not predict ENSO conditions were being compared to temperatures during a period that was dominated by those influences. It’s no wonder that model outputs have been so inaccurate, and it is clear that future modelling must incorporate the ENSO effect if it is to be meaningful’

NASA has now silently released corrected figures, and the changes are truly astounding. The warmest year on record is now 1934. 1998 (long trumpeted by the media as record-breaking) moves to second place. 1921 takes third. In fact, 5 of the 10 warmest years on record now all occur before World War II.

Global warming appears to have stalled. Climatologists are puzzled as to why average global temperatures have stopped rising over the last 10 years. Some attribute the trend to a lack of sunspots, while others explain it through ocean currents.

Himalayan Glacier Mistake
The IPCC asserted in its 2007 report that the Himalayan glaciers would likely melt by 2035 due to global warming, prompting great alarm across southern and eastern Asia, where glaciers feed major rivers.
The mistake has called into question the credibility of the IPCC, which has been considered an authoritative source for information about climate change because of its policy of carefully reviewing and analyzing hundreds and even thousands of published, peer-reviewed scientific studies. -Kevin Bullis, MIT Technology Review
