|Reality proves IPCC wrong : C02 not a problem
|MAN-MADE GLOBAL WARMING IS A MYTH
|The evidence, as published by 3 of the 4 recognized world temperature data recorders**, is the following: there has been no warming since 1998, and in 2008 we are witnessing significant cooling. Sea ice covers the usual area in both the Arctic and the Antarctic; Atlantic and Pacific currents are both in their cooling cycle; and there are no spots on the sun, which has some scientists suggest we may be entering a "little ice age".

Now is the time to take another look at the role of anthropogenic C02 in the evolution of climate. Allan MacRae gives us the facts.
Above picture: Chaiten volcano - Chile, May 2008 : nature´s power on display.
The evidence to date suggests that increased atmospheric CO2 plays NO significant role in causing global warming.
The best data shows no significant warming since ~1940. The lack of significant warming is evident in UAH Lower Troposphere temperature data from ~1980 to end April 2008, and Hadcrut3 Surface Temperature data from ~1940 to ~1980.

Above chart: Surface Temperature is influenced by other factors such as the Urban Island Heat Effect, and the location of temperature recording stations, which suburbia tends to encircle over time with its heat-retaining asphalt and concrete. The global cooling from approximately 1946-1977 coincides with the cool phase of a natural cycle called the Pacific Decadal Oscillation (PDO), and the warming from approximately 1977-2007 coincides with the warming phase of the PDO. NASA announced in 2008 that the PDO has again shifted to its cool phase. Significant cooling was experienced in 2007-2008, and is expected to continue.
Furthermore, it is clear that CO2 lags temperature at all measured time scales, from ice core data spanning thousands of years to sub-decadal trends - the latter as stated in my paper**, and previously by Kuo (1990) and Keeling (1995) .
** My paper
In late November 2007 Pieter Tans** described the close relationship between dCO2/dt and temperature, about one month before I made a similar finding. This is a further step forward in our understanding.
** Tans´ paper
Above Figure 3 from MacRae´s January 2008 paper shows the close relationship between dCO2/dt and temperature, and the approximate 9 month lag of CO2 after temperature.
Finally, human-made CO2 emissions have increased almost 800% since 1940.
CO2 data from CDIAC
This data consistently suggests that the sensitivity of global temperature to increased atmospheric CO2 is near-zero, and thus there is no human-made catastrophic global warming crisis.
Update: The UAH LT global average temperature anomaly dropped another 0.2C in May 2008.

|* Neo Zelandia: Profesor niega que el CO2 sea un problema.
January 29, 2009 • New Zealand
Professor denies greenhouse effect.
Theories of climate change were challenged during an Environment Court appeal hearing for Meridian Energy's proposed $2 billion Project Hayes wind farm yesterday. As a witness for appellant Roch Sullivan, climate scientist Prof Christopher de Freitas was questioned on his evidence, which had been contested in the evidence of other climate witnesses called in the hearing. Prof Freitas, of the University of Auckland, said there was no evidence to suggest carbon dioxide was the major driver of climate change. "Climate is not responding to greenhouse gases in the way we thought it might. If increasing carbon dioxide is in fact increasing climate change, its impact is smaller than natural variation. "People are being misled by people making money out of this," Prof de Freitas said. He said mild warming of the climate was beneficial, especially in a country such as New Zealand, which had a prominent agricultural industry. "One could argue that carbon dioxide is quite beneficial. There may be benefits of wind farming that I may not be aware of, but there is no data to show benefits in terms of mitigating potential dangerous changes in climate by offsetting carbon dioxide," he said. Prof de Freitas said the Kyoto Protocol was a "politically and economically motivated instrument to deal with a perceived problem".
"I don't think anyone will benefit one way or another by adhering to it. It's not a well-formulated treaty... the so-called or claimed environmental benefits, I am not aware of," he said. Prof de Freitas was questioned by Meridian Energy lawyer Hugh Rennie QC, about an article published in The New Zealand Herald in 2004, in which Prof de Freitas expressed his thoughts on wind power, the Kyoto Protocol, and climate change. "You refer to New Zealand's need to meet its commitments to the Kyoto Protocol [in the article]. "Would you accept that any selection of generation which avoids the emission of substances controlled by that protocol is beneficial to New Zealand?" Mr Rennie asked Prof de Freitas.
Prof de Freitas took exception to the question. "You are using legal gymnastics to corner me into a position I would not otherwise take," he said. Prof de Freitas admitted there was debate about climate change, when questioned during cross-examination by Central Otago District Council lawyer Graeme Todd. "The debate centres on causes. There is a possibility climate change could be impacted by human beings, but it is not a significant impact," he said. In response to a question by commissioner Alex Sutherland, Prof de Freitas said the jury was out on climate change, and preemptive action could be dangerous. "There's no basis for alarm. We might be shooting ourselves in the foot if we act on what turns out to be a bubble-less pot," he said.
Panel: Environment Court judge Jon Jackson, commissioner Alex Sutherland, commissioner Heather McConachy, and deputy commissioner Ken Fletcher.
Yesterday: Otago Regional Council water resource scientist Matthew Dale, of Dunedin; climate scientist Prof Christopher de Freitas, of Auckland; Electricity Commission director of transmission John Gleadow, of Wellington.
Scheduled for today: Mr Gleadow will continue to give evidence.
Quote of the day: "Climate is not responding to greenhouse gases in the way we thought it might. If increasing carbon dioxide is in fact increasing climate change, its impact is smaller than natural variation. People are being misled by people making money out of this."
- climate scientist Prof Christopher de Freitas, of Auckland.
