Senator James Inhofe produced a speech on the floor of the Senate recently, his second such speech. The first was in 2005, and covered similar territory. Apparently he was the topic of an unflattering editorial in the NY TImes, which Debra Saunders discusses in today's San Francisco Chronicle.
Global warming is a religion, not science. That's why acolytes in the media attack global-warming critics not with scientific arguments, but for their apostasy. Then they laud global-warming believers not for reducing greenhouse gases, but simply for believing global warming is a coming catastrophe caused by man. The important thing is to have faith in those who warn: The end is near.
What was Inhofe's mistake?
The Times' focus was on Inhofe's refusal to bow to "the consensus among mainstream scientists and the governments of nearly every industrialized nation concerning manmade climate change." That is, Inhofe has had the effrontery to challenge elite orthodoxy. Or, as the editorial put it, Inhofe "has really buttressed himself with the will to disbelieve."
"Disbeliev[ing]" is the crime, apparently. Inhofe is an apostate. There are really two camps in the global-warming debate. One believes that global warming has had a precipitous acceleration due to man's activities, primarily the burning of fossil fuels, in the latter half of the 20th century. The other group, the skeptics, are often mischaracterized as not believing that global warming is occurring. Largely, though what they believe is that global warming has been neither precipitous nor unprecedented, and it hasn't been due primarily to man, but rather to natural variance from solar activity and other factors. This latter group got another boost to their hypothesis recently.
Ten years ago, Danish researchers Henrik Svensmark and Eigil Friis-Christensen first hypothesized that cosmic rays from space influence the Earth’s climate by effecting cloud formation in the lower atmosphere. Their hypothesis was based on a strong correlation between levels of cosmic radiation and cloud cover – that is, the greater the cosmic radiation, the greater the cloud cover. Clouds cool the Earth’s climate by reflecting about 20 percent of incoming solar radiation back into space.
The hypothesis was potentially significant because during the 20th century the influx of cosmic rays was reduced by a doubling of the sun’s magnetic field which shields the Earth from cosmic rays. According to the hypothesis, then, less cosmic radiation would mean less cloud formation and, ultimately, warmer temperatures – precisely what was observed during the 20th century.
If correct, the Svensmark hypothesis poses a serious challenge to the current global warming alarmism that attributes the 20th century’s warmer temperatures to manmade emissions of greenhouse gases.
Just last week, Svensmark and other researchers from the Centre for Sun-Climate Research at the Danish National Space Centre published a paper in the Proceedings of the Royal Society A – the mathematical, physical sciences and engineering journal of the venerable Royal Society of London – announcing that they had experimentally verified the physical mechanism by which cosmic rays affect cloud cover.
This is big news - thus far unreported by big media.
“Many climate scientists have considered the linkages from cosmic rays to clouds as unproven,” said Friis-Christensen who is the director of the Danish National Space Centre. “Some said there was no conceivable way in which cosmic rays could influence cloud cover. [This] experiment now shows they do so, and should help to put the cosmic ray connection firmly onto the agenda of international climate research,” he added.
How significant could this effect be?
That is, cloud cover changes over a 5-year period can have 85 percent of the temperature effect on the Earth that has been claimed to have been caused by nearly 200 years of manmade carbon dioxide emissions. The temperature effects of cloud cover during the 20th century could be as much as 7 times greater than the alleged temperature effect of 200 years worth of additional carbon dioxide and several times greater than that of all additional greenhouse gases combined.
So although it has been taken for granted by global warming alarmists that human activity has caused the climate to warm, Svensmark’s study strongly challenges this assumption.
Ms. Saunders concludes:
I remain agnostic on global warming, as I've seen good arguments on both sides. I know, however, that I never will be convinced that global warming is a scientific threat as long as believers put most of their energy into establishing orthodoxy and denying that reputable global-warming skeptics exist.
She then lists some of the reputable skeptics. That those skeptics, backed with similarly impressive scientific studies like the one referenced above, are treated like holocaust deniers, speaks poorly not of the skeptics, but of the global-warming true believers, one of whom has even proposed Nuremburg style trials for the crime of denial.
Scared of the debate?
