Scientists who are part of the 'Science Is Settled' mob are quite adamant that there is no room for discussion, that climate change is caused solely by marginally increased levels of the trace atmospheric gas Carbon Dioxide is proved beyond doubt. Unfortunately their 'proof' exists only in mathematical models, studies based on real world evidence constantly disagree.
The Daily Stirrer has always said that the Global Warming scare is based on evidence obtained solely from computer generated mathematical models of the global climate and differs widely from real world data.
Here's what Xavier Connolly (not his real name) The Daily Stirrer engineering expert wrote on the topic some time ago:
Global Warming - The Real Science by Xavier Connolly
Climate Science is stupid. Stupid is ignoring known facts. Here are some crucial, verifiable facts - with citations - that people should be aware of concerning human-generated carbon dioxide and its effect on global warming. (I recommend following the links in the citations; some of them are very educational.)
The fact is, there has been global warming, but the contribution of human-generated carbon dioxide is necessarily so minuscule as to be nearly undetectable. Here's why:
Carbon dioxide, considered the main vector for human-caused global warming, is some 0.038% of the atmosphere[1]- a trace gas. Water vapor varies from 0% to 4%[2], and should easily average 1% or more[3] near the Earth’s surface, where the greenhouse effect would be most important, and is about three times more effective[4] a greenhouse gas than carbon dioxide. So water vapor is at least 25 times more prevalent and three times more effective; that makes it at least 75 times more important to the greenhouse effect than carbon dioxide[5].
The TOTAL contribution of carbon dioxide to the greenhouse effect is therefore 0.013 or less. The total human contribution to atmospheric carbon dioxide since the start of the industrial revolution has been estimated at about 25%[6]. So humans’ carbon dioxide greenhouse effect is a quarter of 0.013, works out to about 0.00325. Total warming of the Earth by the greenhouse effect is widely accepted as about 33 degrees Centigrade, raising average temperature to 59 degrees Fahrenheit. So the contribution of anthropogenic carbon dioxide is less than 0.2 degrees Fahrenheit, or under 0.1 degree Centigrade. Global warming over the last century is thought by many to be about 0.6 degrees Centigrade.
But that's only the beginning. We've had global warming for more than 10,000 years, since the end of the last Ice Age, and there is evidence temperatures were actually somewhat warmer 9,000 years ago and again 4,500 to 8,000 years ago than they are today[7]. Whatever caused that, it was not human activity. It was not all those power plants and factories and SUVs being operated by Stone Age cavemen while chipping arrowheads out of bits of flint.
Whatever the cause was, it melted the glaciers that in North America once extended south to Long Island and parts of New York City[8] into virtually complete disappearance (except for a few mountain remnants). That's one big greenhouse effect! If we are still having global warming - and I suppose we could presume we are, given this 10,000 year history - it seems highly likely that it is still the overwhelmingly primary cause of continued warming, rather than our piddling 0.00325 contribution to the greenhouse effect.
Yet even that trend-continuation today needs to be proved. Evidence is that the Medieval Warm Period centered on the 1200s was somewhat warmer than we are now[9], and the climate was clearly colder in the Little Ice Age in the 1600s than it is now[10]. So we are within the range of normal up-and-down fluctuations without human greenhouse contributions that could be significant, or even measurable.
The principal scientists arguing for human-caused global warming have been demonstrably disingenuous[11], and now you can see why. They have proved they should not be trusted.
The idea that we should be spending hundreds of billions of dollars and hamstringing the economy of the entire world to reduce carbon dioxide emissions is beyond ludicrous in light of the facts above; it is insane.
Furthermore, it sucks attention and resources from seeking the other sources of warming and from coping with climate change and its effects in realistic ways. The true motivation underlying the global warming movement is almost certainly ideological and political in nature, and I predict that anthropogenic Global
Warming, as currently presented, will go down as the greatest fraud of all time. It makes Ponzi and Madoff look like pikers by comparison.

This source is listed for its good discussion of the phenomena determining that range. An examination of a globe will show that tropical oceans (near high end of range) are far more extensive than the sum of the earth’s arctic and antarctic regions and tropical-zone deserts (all near the low end). Temperate zone oceans are far more extensive than temperate-zone desert. This author’s guess of an average of 2% or more seems plausible. I have used “1% or more” in an effort to err on the side of understatement.

Including all the atmosphere would change the ratios to about 20 times more prevalent and 60 times more effective. However, the greenhouse effect of high-altitude carbon dioxide on lower-altitude weather and the earth’s surface seems likely to be small if not nil. HYPERLINK
