“The data doesn’t matter. We’re not basing our recommendations
on the data. We’re basing them on the climate models.”
– Prof. Chris Folland,

What kind of scientists does not continue questioning or does not use accurate scientific data? The kind that are politically motivated is the answer.
There has been almost no global warming since about 2000. The impact of CO2 on the warming of the planet is much less than what was previously thought. Nothing should be done about CO2 for decades. Forecasts of global warming have been exaggerated. Increased CO2 is having a positive effect. CO2 is actually good in many ways such as food production and drought resistance. That comes from at least 16 esteemed scientists who signed on to this and other ideas from a WSJ article linked below.
Princeton physics professor William Happer –
WSJ:…In September, Nobel Prize-winning physicist Ivar Giaever, a supporter of President Obama in the last election, publicly resigned from the American Physical Society (APS) with a letter that begins: “I did not renew [my membership] because I cannot live with the [APS policy] statement: ‘The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth’s physical and ecological systems, social systems, security and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now.’ In the APS it is OK to discuss whether the mass of the proton changes over time and how a multi-universe behaves, but the evidence of global warming is incontrovertible?” …
…A recent study of a wide variety of policy options by Yale economist William Nordhaus showed that nearly the highest benefit-to-cost ratio is achieved for a policy that allows 50 more years of economic growth unimpeded by greenhouse gas controls. This would be especially beneficial to the less-developed parts of the world that would like to share some of the same advantages of material well-being, health and life expectancy that the fully developed parts of the world enjoy now. Many other policy responses would have a negative return on investment. And it is likely that more CO2 and the modest warming that may come with it will be an overall benefit to the planet…Keep Reading…
In the 1970’s, scientists were certain that an ice age was coming –
Coming Ice Age: …Despite many claims to the contrary, the 1970’s global cooling fears were widespread among many scientists and in the media. Despite the fact that there was no UN IPCC organization created to promote global cooling in the 1970s and despite the fact that there was nowhere near the tens of billions of dollars in funding spent today to promote man-made global warming, fears of a coming ice age, showed up in peer-reviewed literature, at scientific conferences, voiced by prominent scientists and throughout the media.
Newsweek Magazine even used the climate “tipping point” argument in 1975. Newsweek wrote April 28, 1975 article: “The longer the planners delay, the more difficult will they find it to cope with climatic change once the results become grim reality.”
But on October 24, 2006, Newsweek admitted it erred in predicting a coming ice age in the 1970’s. (NYT: Obama’s global warming promoting science czar Holdren ‘warned of a coming ice age’ in 1971 – September 29, 2009 & also see: NASA warned of human caused coming ‘ice age’ in 1971 – Washington Times – September 19, 2007 and also see: 1975 New York Times: “Scientists Ask Why World Climate is Changing, Major Cooling May Be Ahead”, May 21, 1975 and see: 1974 Time Magazine: “Another Ice Age,” June 24, 1974
A Small Sampling of 1970’s Reports Warning of Global Cooling:
Excerpt: “A major climatic change would force economic and social adjustments on a worldwide scale,” warns a recent report by the National Academy of Sciences, “because the global patterns of food production and population that have evolved are implicitly dependent on the climate of the present century.” – Newsweek – April 28, 1975 “The Cooling World”
Excerpt: “The world “could be as little as 50 or 60 years away from a disastrous new ice age, a leading atmospheric scientist predicts,” read a July 9, 1971 Washington Post article. NASA scientist S.I. Rasool, a colleague of James Hansen, made the predictions. The 1971 article continues: “In the next 50 years” — or by 2021 — fossil-fuel dust injected by man into the atmosphere “could screen out so much sunlight that the average temperature could drop by six degrees,” resulting in a buildup of “new glaciers that could eventually cover huge areas.” If sustained over “several years, five to 10,” or so Mr. Rasool estimated, “such a temperature decrease could be sufficient to trigger an ice age.”…Keep Reading…
