Solar activity 'not behind climate change'   3 April 2008
The research, carried out by physicists at Lancaster University, undermines claims by climate sceptics that cosmic rays are key drivers in cloudiness and temperature. The theory claims that variation in solar activity leads to a corresponding variance in cosmic rays.

NYC Climate Conference Further Debunks ‘Consensus’ Claims
Climate Skeptics Reveal ‘Horror Stories’ of Scientific Suppression
Written by George Landrith - Tuesday, 11 March 2008

Scientists skeptical of man-made climate fears meeting at the 2008 International Conference on Climate Change in New York City described the “absolute horror stories” about how some scientific journals have engaged in “outrageous and unethical behavior” in attempting to suppress them from publishing their work in peer-reviewed journals. The March 2-4 groundbreaking conference, which featured about 100 speakers with over 500 people attending, presented the report of a team of international scientists who formed a group to counter the UN IPCC.

The event, which garnered significant international and U.S. media attention, featured many current and former UN IPCC scientists from around the world. The international climate conference built on the momentum of growing number of skeptics as the conference showcased a new report by a team of international scientists who formed a group to counter the UN IPCC called the “Nongovernmental International Panel of Climate Change” (NIPCC). The skeptical scientist report was titled “Nature, Not Human Activity, Rules the Climate.”

Key findings of the NIPCC’s climate findings:

(1) Most of climate change is caused by natural forces.
(2) The human contribution is not significant.
(3) Solar-activity changes are the main cause of climate change.

Climate Scientist Dr. S. Fred Singer, former director the US Weather Satellite Service and past vice chairman of the U.S. National Advisory Committee on Oceans and Atmosphere, told the conference that the IPCC “chose to ignore these facts, because they conflicted with the conclusion that global warming is anthropogenic (man-made).

So it appears that Arctic ice isn't vanishing after all
National Oceanic and Atmospheric Administration (NOAA) on the website Cryosphere Today by the University of Illinois presents a graph of the northern hemisphere sea ice area, which shows the ice shrinking from 13 million sq km to just 4 million during spring/summer 2007, and now it is almost back to 13 million sq km in February 08.

“Global warming has stopped,” said David Whitehouse, former science editor for the BBC. “It’s not a viewpoint or a skeptic’s inaccuracy. It’s an observational fact.” But the observational fact matters little to global warming alarmists, particularly those in the media.

Over 400 prominent scientists from more than two dozen countries recently voiced significant objections to major aspects of the so-called "consensus" on man-made global warming. These scientists, many of whom are current and former participants in the UN IPCC (Intergovernmental Panel on Climate Change), criticized the climate claims made by the UN IPCC and former Vice President Al Gore.

Finland: Dr. Boris Winterhalter, retired Senior Marine Researcher of the Geological Survey of Finland and former professor of marine geology at University of Helsinki, criticized the media for what he considered its alarming climate coverage. “The effect of solar winds on cosmic radiation has just recently been established and, furthermore, there seems to be a good correlation between cloudiness and variations in the intensity of cosmic radiation. Here we have a mechanism which is a far better explanation to variations in global climate than the attempts by IPCC to blame it all on anthropogenic input of greenhouse gases. “

Britain: Dr. Richard Courtney, a UN IPCC expert reviewer and a UK-based climate and atmospheric science consultant: “To date, no convincing evidence for AGW (anthropogenic global warming) has been discovered. And recent global climate behavior is not consistent with AGW model predictions.”
