Global Dimming of the Sun is created by particulate matter in the atmosphere creating conditions that reflect sun energy back into space resulting in a cooling effect on the planet. Although it seems that the developed nations are creating more of the CO2 (the Global Warming agent), we have been steadily reducing our particulate discharge over the last 50 years. It is the developing countries (seen the video-feeds from the Beijing Olympics?) that are spewing the particles.

The show was somewhat sensational and alarmist; no one presented a dissenting opinion; and, of course, it was politically correct: Global Warming was not questioned – e.g. the show said a majority of scientists believe it. Well, as I once heard said, science is not about consensus; it is about developing theories and models and refining them until they accurately reflect reality. People forget that in 1860 most scientists believed in creation and disparaged Darwin’s theory of evolution. Suppose they had taken a vote on that?

There were a couple of things one could intuit from the show. One scientist was saying how the standard Global Warming model did not predict the drought that devastated much of the Sahara in the 70s and 80s. Once he added Global Dimming to the mix, he was better able to model those climate changes. Message: you never know if your model is accurate until its predictions come to pass. One errant assumption, one unknowable process and everything is out the window.

Also, it seemed pretty clear that the piece was suggesting that a great deal of recent weather pattern change can be attributed to the Global Dimming. Perhaps Global Warming is not changing the weather as much as some think and reducing the CO2 may not have much impact on that. However, if we get China and India to reduce particulate matter, we will lose the cooling effect of dimming the sun, leading to faster Global Warming (assuming that it is driven by civilisation’s CO2), but we may also save hundreds of thousands of lives lost to true pollution.

What a dilemma! Spew more particles to reduce global warming and increase illness or try to reduce both particulate and CO2 with the hope of solving all of our problems.

One big take away from the show, if you did any thinking, was the hubris of humans, particularly those in the West, about our ability to control things. Hell, we have invented plastics, cars, airplanes, personal computers and iPhones. We have put men on the moon and space craft on most of the other planets. We have eliminated many devastating diseases and have harnessed nature for our benefit. There ain’t nothing we can’t do! We can heat up the planet or cool it off.

Bjorn Lomborg (The Sceptical Environmentalist) has released another book, Cool It: The Sceptical Environmentalist’s Guide to Global Warming, in which he questions the effectiveness of combating global warming. He says that even the optimists figure that Kyoto, if fully implemented, will have minimal impact on slowing rising temperatures. And the cost would be enormous. Why not, he suggests, spend the money on something that we know for sure will benefit humanity: eliminate malaria, cure AIDS, more direct investment in the third world… the opportunities are endless.

Others have suggested that climate change is inevitable and unstoppable. Better that we prepare for unruly weather than try to stop it. Besides, the greatest threat to civilisation is another gigantic meteorite slamming into the earth. The last one hit 65 million years ago, created the Gulf of Mexico, and destroyed 95% of the life on earth. The other threat is Super Volcanoes. The last one erupted 75,000 years ago in Sumatra with 10,000 times the power of Mount St Helen’s. It is believed to have killed 75% of the plant life in North America. Yellowstone National park sits on one that erupts regularly every 640,000 years. The last time it blew was 600,000 years ago.

Let’s face it; we are doomed one way or the other.

International Climate Science Coalition releases signatories to the Manhattan Declaration on Climate Change

Ottawa, Canada, April 22, 2008 – The International Climate Science Coalition (ICSC) today released the names of over 500 endorsers of the Manhattan Declaration on Climate Change that calls on world leaders to “reject the views expressed by the United Nations Intergovernmental Panel on Climate Change (IPCC) as well as popular, but misguided works such as “An Inconvenient Truth”.” All taxes, regulations, and other interventions intended to reduce emissions of carbon dioxide (CO2) should “be abandoned forthwith”, declaration signatories conclude.

Included in the endorser list are world leading climate scientists, economists, policymakers, engineers, business leaders, medical doctors, as well as other professionals and concerned citizens from two dozen countries. The complete declaration text, endorser lists and international media contacts for expert commentary, may be viewed at here.

Perhaps most significant among the declaration’s assertions:

• “there is no convincing evidence that CO2 emissions from modern industrial activity have in the past, are now, or will in the future cause catastrophic climate change.”

• “attempts by governments to legislate costly regulations on industry and individual citizens to encourage CO2 reduction will slow development while having no appreciable impact on the future trajectory of global climate change. Such policies will markedly diminish future prosperity and so reduce the ability of societies to adapt to inevitable climate change, thereby increasing, not decreasing human suffering.”

“Just as the Manhattan Project was key to finally ending the Second World War, the Manhattan Declaration on Climate Change may one day be regarded as a critical catalyst that helped end today’s climate hysteria,” said ICSC Science Advisory Board member, Professor Bob Carter of James Cook University in Australia. “Protecting the natural world is crucially important and so environmental policy must be based on our best understanding of science and technology coupled with a realistic appreciation of the relevant economics and policy options. This is not happening in the climate debate.”

ICSC Chair, Professor Tim Patterson of Carleton University in Ottawa, Canada concludes, “Instead of wasting billions restricting emissions of CO2, a vitally important gas on which all life depends, governments must concentrate on solving known environmental problems over which we have influence – air, land and water pollution being obvious examples.“

The ICSC is an association of scientists, economists and energy and policy experts (advisors listed here) working to promote better public understanding of climate change. ICSC provides an analysis of climate science and policy issues which, being independent of lobby groups and vested political interests, is an alternative to advice from the IPCC. ICSC thereby fosters rational, evidence-based, open discussion about all climate, and climate-related, issues.
