Quote: “Since 1895, the media has alternated between global cooling and warming scares during four separate and sometimes overlapping time periods. From 1895 until the 1930’s the media peddled a coming ice age. From the late 1920’s until the 1960’s they warned of global warming. From the 1950’s until the 1970’s they warned us again of a coming ice age. This makes modern global warming the fourth estate’s fourth attempt to promote opposing climate change fears during the last 100 years.”

Here is a more complete timeline straight from the headlines and texts of leading newspapers and other reliable sources, thanks to http://butnowyouknow.net/those-who-fail-to-learn-from-history/climate-change-timeline/ and other reliable documentation as noted below.

• 1872 John Tyndall measured the heat absorption of various atmospheric gases over the entire wavelength range of his heat source. He found that water vapor and CO₂ absorbed more strongly than other atmospheric gases such as oxygen and nitrogen. Oxygen and nitrogen, major components of the atmosphere, had little or no absorption of heat in the range tested. It is important to note that his experiments did not separate the heat into specific wavelengths. See Claim 2 and its chart in the next blog post.

Quote: “…if, as the above experiments indicated, the chief influence be exercised by the aqueous vapour, every variation of this constituent must produce a change of climate. Similar remarks would apply to the carbonic acid [CO₂] diffused through the air… they constitute true causes, the extent alone of the operation remaining doubtful.”

Quote: “ … average surface temperature of the earth increases 3.6^o C if the CO₂ concentration in the atmosphere is doubled …” (this is the false assumption on which many computer models rest)

Quote: “The extra CO₂, released into the atmosphere by industrial processes and other human activities may have caused the temperature rise during the present century. In contrast with other theories of climate, the CO₂ theory predicts that this warming trend will continue, at least for several centuries.”

Quote: “The 1995 IPCC draft report said, ‘Any claims of positive detection of significant climate change are likely to remain controversial until uncertainties in the total natural variability of the climate system are reduced.’ It also said, ‘No study to date has positively attributed all or part of observed climate changes to anthropogenic causes.’ Those statements were removed, and in their place appeared: ‘The balance of evidence suggests a discernable human influence on climate.'”  (emphasis added)

Quote: “I readily confess a lingering frustration: uncertainties so infuse the issue of climate change that it is still impossible to rule out either mild or catastrophic outcomes, let alone provide confident probabilities for all the claims and counterclaims made about environmental problems. Even the most credible international assessment body, the Intergovernmental Panel on Climate Change (IPCC), has refused to attempt subjective probabilistic estimates of future temperatures. This has forced politicians to make their own guesses about the likelihood of various degrees of global warming.” (emphasis added)

Quote: “On the one hand, as scientists we are ethically bound to the scientific method, in effect promising to tell the truth, the whole truth, and nothing but — which means that we must include all the doubts, the caveats, the ifs, ands, and buts. On the other hand, we are not just scientists but human beings as well. And like most people we’d like to see the world a better place, which in this context translates into our working to reduce the risk of potentially disastrous climatic change.

To do that we need to get some broadbased support, to capture the public’s imagination. That, of course, entails getting loads of media coverage. So we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have. This ‘double ethical bind’ we frequently find ourselves in cannot be solved by any formula. Each of us has to decide what the right balance is between being effective and being honest. I hope that means being both.” (emphasis added. Note that the excuse for dishonesty is based on an unsubstantiated assumption that doing so will result in a better world.)
