“Consensus” on Man-Made Warming Shattering

Gore’s (Really) Inconvenient Timing - ‘Consensus’ On Man-Made Global Warming Collapses in 2008

By Marc Morano, EPW Blog

Former Vice-President Al Gore came to Washington on July 17, 2008, to deliver yet another speech warning of the “climate crisis.” “The leading experts predict that we have less than 10 years to make dramatic changes in our global warming pollution lest we lose our ability to ever recover from this environmental crisis,” Gore stated. But the former Vice President, who has been warning of a 10-year “tipping point” for several years now, appears to be unaware that the United Nations already started the 10 year countdown in 1989!

According to July 5, 1989, article in the Miami Herald, the then-director of the New York office of the United Nations Environment Program (UNEP), Noel Brown, warned of a “10-year window of opportunity to solve” global warming. According to the 1989 article, “A senior U.N. environmental official says entire nations could be wiped off the face of the Earth by rising sea levels if the global warming trend is not reversed by the year 2000. Coastal flooding and crop failures would create an exodus of ‘eco-refugees,’ threatening political chaos.”

While Gore repeats his standard stump speech promoting man-made climate fears, much of the international science community is now openly dissenting from human caused global warming fears.

See in this summary a very small sampling of very inconvenient developments for Gore, the United Nations, and the mainstream media. Peer-reviewed studies, analyses, and prominent scientists continue to speak out to refute climate fears. The vast majority of data presented is from just the past month. Part II expands on this list of papers and stories.

Global temps since first UN warning of 10 years left to save the planet in 1989. Note Pinatubo produced cooling in the early to mid 1990s. See large graph here. This chart show 20 years after the UN warned we had only 10 years to save the planet from a heat related catastrophe, global temperatures have not changed.

No Smoking Hot Spot

By David Evans, the Australian

I devoted six years to carbon accounting, building models for the Australian Greenhouse Office. I am the rocket scientist who wrote the carbon accounting model (FullCAM) that measures Australia’s compliance with the Kyoto Protocol, in the land use change and forestry sector. FullCAM models carbon flows in plants, mulch, debris, soils and agricultural products, using inputs such as climate data, plant physiology and satellite data. I’ve been following the global warming debate closely for years.

When I started that job in 1999 the evidence that carbon emissions caused global warming seemed pretty good: CO2 is a greenhouse gas, the old ice core data, no other suspects. The evidence was not conclusive, but why wait until we were certain when it appeared we needed to act quickly? Soon government and the scientific community were working together and lots of science research jobs were created. We scientists had political support, the ear of government, big budgets, and we felt fairly important and useful (well, I did anyway). It was great. We were working to save the planet.

But since 1999 new evidence has seriously weakened the case that carbon emissions are the main cause of global warming, and by 2007 the evidence was pretty conclusive that carbon played only a minor role and was not the main cause of the recent global warming. As Lord Keynes famously said, “When the facts change, I change my mind. What do you do, sir?”

There has not been a public debate about the causes of global warming and most of the public and our decision makers are not aware of the most basic salient facts: 1. The greenhouse signature is missing. We have been looking and measuring for years, and cannot find it. Each possible cause of global warming has a different pattern of where in the planet the warming occurs first and the most. The signature of an increased greenhouse effect is a hot spot about 10km up in the atmosphere over the tropics. We have been measuring the atmosphere for decades using radiosondes: weather balloons with thermometers that radio back the temperature as the balloon ascends through the atmosphere. They show no hot spot. Whatsoever. If there is no hot spot then an increased greenhouse effect is not the cause of global warming. So we know for sure that carbon emissions are not a significant cause of the global warming. If we had found the greenhouse signature then I would be an alarmist again. When the signature was found to be missing in 2007 (after the latest IPCC report), alarmists objected that maybe the readings of the radiosonde thermometers might not be accurate and maybe the hot spot was there but had gone undetected. Yet hundreds of radiosondes have given the same answer, so statistically it is not possible that they missed the hot spot. Recently the alarmists have suggested we ignore the radiosonde thermometers, but instead take the radiosonde wind measurements, apply a theory about wind shear, and run the results through their computers to estimate the temperatures. They then say that the results show that we cannot rule out the presence of a hot spot. If you believe that you’d believe anything.

Dr David Evans was a consultant to the Australian Greenhouse Office from 1999 to 2005.
