Another Brave Scientist Tells The Truth About Global Warming.....

The following statement by another geologist (this time from New Zealand) is a well-said summary of the distortions of reality the public is being told concerning global warming. The best statement in this short article is:

"Few scientists are willing to put their head above the parapet, for a variety of reasons, not the least of which is that, to paraphrase Voltaire, it is dangerous to be right when the authorities are wrong."

This explains why so few scientists are willing to publicly dispute the idea that man is causing global warming and climate change. They are afraid. Political correctness is a powerful influence on peoples behavior. But we are now seeing more and more scientists willing to voice the truth.

Chris de Freitas: Don't blame me for the heat
(Dr Chris de Freitas is an associate professor in the School of Geography, Geology and Environmental Science, University of Auckland)

Greenpeace spokeswoman Susannah Bailey's attack on branches of the New Zealand business sector, which she accuses of continuing to plead grey on global warming, misses the key point. Political action on climate change is not a game to be played and won or lost, and Greenpeace does us a disservice by encouraging that view. Little does the public realise the debate over climate change usually conflates issues of science and politics.

The robustness (validity) or otherwise of the science underpinning the role of greenhouse gases in the atmosphere is the key to assessing the risk from human induced climate change issue. But seldom if ever are the uncertainties of the science discussed. Seldom if ever is the question asked: Where is the evidence for catastrophic climate change from human action?

Rather than search for the evidence, groups like Greenpeace defer to authorities, such as the Intergovernmental Panel on Climate Change (IPCC), a political entity which appears to have a monopoly on wisdom in global warming matters.

Rather than debate the issues, they attack those who disagree, using defamatory labels. Yet the opposite of scepticism is gullibility. The fanatical name calling and personal attacks expose the strong ideological elements that drive global warming alarmist thinking. It's as if the depth of passion is overcompensation for doubt and uncertainty. Why else would environmentalists squander so much effort trying to discredit individuals and organisations who disagree?

Few scientists are willing to put their head above the parapet, for a variety of reasons, not the least of which is that, to paraphrase Voltaire, it is dangerous to be right when the authorities are wrong.

Moreover, vote counting is a risky way to discover scientific truth. Scientific validity is not determined by a show of hands. Pronouncements from Greenpeace or the IPCC do not and cannot change the facts. No one doubts humans affect climate. The debate is whether the effects are "dangerous". There is no hard evidence that increases in carbon dioxide in the atmosphere put there by human activities are causing or will cause dangerous change to global climate.

The Earth's surface has warmed slightly over the last 150 years, but research shows that floods, droughts, hurricanes and tornadoes have not increased in frequency. The climate facts are well established and well recorded, but often ignored when it comes to global warming catastrophism:*

There have been four periods of global warming in the past 1500 years.* Data clearly show the Earth cooled during a recent 35-year period despite the continuing rise of carbon dioxide in the atmosphere.* In recent times, global temperature has been steady since 1998, despite the continuing rise of carbon dioxide in the atmosphere.* Average global sea level rise has shown no acceleration over the past 300 years.*

And it is an uncontroversial fact that all climate models are unreliable, so their output is not evidence of anything.

Recent climate change is within natural variation, and although this in no way confirms that it is due to natural variation, climate history clearly demonstrates that natural variation can explain the moderate climate change we have seen up until 1998. One could argue that we should take the observed net 0.6C warming trend over the past 100 years seriously, but by itself it looks rather benign, and may even be beneficial.

Even if the signatories to the Kyoto protocol meet their commitment, the climate science community is unanimous on the view that its impact on global warming would be imperceptible.

The fact is that the Kyoto targets are not based on science. Taking into account the economic costs, the Kyoto Protocol could be worse than doing nothing. It fails to establish long-term goals based on science, it poses serious and unnecessary risks to national economies, and it is ineffective in addressing climate change because it excludes major parts of the world. There is a desperate need for balanced reporting to redress widespread misunderstanding of climate change and the role of human activities.

Peter...Alas, my missives of yesterday failed to appear, so I am doing something wrong. I will do a test.

Ah! I see I have to type in the strange letters twice. I must have forgotten.
I was commenting that Chris de Freitas is indeed a brave young researcher, as he is an associate professor, and thus, has no tenure to protect him. Look what happened to Lubos Motl at Harvard because of his blogging activities. Now, if you'll excuse me, I must go read your latest postings.

I'm glad you got on. I don't know about Lubos Motl at Harvard. What is the deal?

I believe it is true that younger scientists, with their jobs on the line, are reluctant to speak out publicly against the idea of man-caused global warming. Maybe that will change. It is not proper, or good for scientists to be muzzled.
