Heartland Update: The Problems with IPCC’s Conclusions on Global Warming
Posted March 9th, 2009 at 5.16pm in Energy and Environment.
As many know, much of the global warming hysteria around the world is derived from the conclusions of the U.N. Intergovernmental Panel on Climate Change (IPCC), which warns that human activity is causing the world to become dangerously warm. Al Gore, who projects 20-foot sea-level raises over an unspecified time period, considers the IPCC report the magnum opus for climate change evidence.
Scientists in some respects are being paid to make, at best, guesses or projections of how climate change actually works and what temperatures will be like in the future. In reality, there is little actual science in the IPCC report. J. Scott Armstrong, a professor at the Wharton school at he University of Pennsylvania, stressed although there were over 2,500 scientists that signed the report, the message was controlled by only a few individuals.
Terry Dunleavy, the executive vice-chairman of the International Climate Science Coalition and honorary executive director of the New Zealand Climate Science Coalition, emphasized that no definitive conclusion can be reached when it comes to the science of global warming. In fact, IPCC scientists’ own conclusion admitted they were highly uncertain about future climate change or the impacts of human carbon dioxide emissions.
In a recent article by Kesten C. Green, J. Scott Armstrong, and Willie Soon, the authors convincingly argue that climate change models are useless for forecasting:
“Scientific forecasting research has shown that experts aren’t able to provide accurate predictions in this kind of complex and uncertain situation. It doesn’t matter whether experts present their forecasts as certain outcomes, detailed scenarios, expectations, likelihoods or probabilities. Or that the forecasts are the product of hard thinking by many highly qualified experts, or even of mathematics or computer simulations. The expert forecasts are nonetheless worthless.
The models employed by James Hansen and the IPCC are not based on scientific forecasting principles. There is no empirical evidence that they provide long-term forecasts that are as accurate as forecasting that global average temperatures won’t change. Hansen’s, and the IPCC’s, forecasts, and the recommendations based on them, should be ignored.
This lack of credible climate forecasts matters, because proposed policies – including taxing carbon emissions and cap-and-trade regimes – will increase energy prices, cause major wealth transfers, and cost jobs. It would be immoral to impose such punishing policies on the basis of dodgy forecasts.”

So much for scientific consensus.

Thinking people all over the world are realizing that man-made global warming is a hoax that threatens our future and the future of our children. The Pope is right about the dangerous dogma of the environmentalist movement. So is Vaclav Klaus, president of the European Union, when he states that “environmentalism is the new communism and climate change is a DANGEROUS myth.”
In agreement with the Pope and Klaus, more than 650 international scientists dissent over the man-made global warming claims. They are more than 12 times the number of UN scientists (52) who authored the media-hyped IPCC 2007 Summary for Policymakers. http://epw.senate.gov/public/index.cfm?FuseAction=Minority.Blogs&ContentRecord_id=2674e64f-802a-23ad-490b-bd9faf4dcdb7
Additionally, more than 31,000 American scientists have signed onto a petition that states, “There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth’s atmosphere and disruption of the Earth’s climate…” http://www.petitionproject.org/index.html
“Progressive” (communist) politicians like Obama seem determined to force us to swallow the man-made global warming scam. We need to defend ourselves from the UN and these politicians, who threaten our future and the future of our children. Based on a lie, they have already wasted billions and plan to increase taxes, limit development, and enslave us.
If not stopped, the global warming scam will enrich the scammers (Gore and Obama’s Wall Street friends), increase the power of the U.N. and communists like Obama, and multiply poverty and servitude for the rest of us.
