Henrik Svensmark, head of solar research at Denmark’s Technical University in Copenhagen, is one of them. And he ventures far ahead in the climate debate, the research with perhaps the greatest significance of our time. His research is contested, of course. Nevertheless, Svensmark and his critics agree that the topic “sun” deserves more attention in climate research. The participants are particularly interested in the complex interplay between our central star and ionizing emissaries from the depths of the galaxy – “cosmic radiation”.
Svensmark says: “The climate is influenced more by changes in cosmic radiation than by carbon dioxide”. CO2 has an effect, of course, “but it is far less than most current climate models assume, and also less than the influence of cosmic radiation”. In his opinion, a doubling of the greenhouse gas in the atmosphere would cause an increase in global temperature of at most one degree, and not two degrees, as is now generally accepted.
In other words, the “climate sensitivity” of carbon dioxide is only half as high as assumed (…)

There have been articles on WUWT recently, here and here, commemorating the 30 years since James Hansen gave Senate committee testimony about his view of the human influence on climate
(…)
Hansen dramatically emphasized that “The most recent two seasons (Dec.-Jan.-Feb and Mar.-Apr.-May, 1988) are the warmest in the entire record.” This is really a non sequitur. It would be notable if the last point(s) in a long upward-trending series were not the warmest in the series. And, indeed, the 27 seasons preceding the two 1988 record temperatures were all lower than the 1981 seasonal high! (See the next graph, below) Basically, Hansen got lucky again that he had a couple of warm seasons that allowed him to make such a statement to impress the uncritical Senators. Otherwise, he would have had to truncate his graph at 1981 to make a similar claim. He also added an extra season of data to his ‘30-year’ time-series, probably to accentuate the claim. Two seasons sounds more impressive than one season.

Very few people realize that the entire concerns about peak oil were based on misinformation or junk science.
A decade ago, the media was filled with stories about peak oil, numerous books were published on the subject (such as Half Gone and $20 a Gallon!), and even the Simpsons mentioned it in an episode about doomsday preppers. Now, the topic is largely forgotten and the flavor of the month is peak oil demand. Anyone concerned about the quality of research that works its way into the public debate should be curious about how so many were so wrong for so long. (Buy my book for the full story.)
First and foremost, realize that in the 1970s, numerous analysts and institutions made similar arguments, arguing that geological scarcity was responsible for higher prices not the two disruptions of production in 1973 and 1979. Indeed, in the months before oil prices collapsed in 1986, the consensus was that prices were too low and had to rise to make upstream investment profitable, despite the fact that OPEC production was collapsing (down from 30 mb/d in 1980 to 15 in 1985). You would think that this would make people more skeptical about claims that geological scarcity was responsible when the shutdown of Venezuelan production and the second Gulf War cut off Iraqi supplies sent prices higher starting in 2003.
