Mike McKain asked me to "clarify a bit by what you mean when you say "climate change" is a doctrine of faith?"I have been doing a fair bit of reading on it, and highly recommend
The Little Ice Age by Brian Fagan, which I will review sometime this week. In it, Brian Fagan details the effects of the climate swings in Europe specifically between 1300 and 1850.
The main point of cention with global warming theory is whether or not humans are causing it, and how much the Earth is going to warm. Computer models are usually used to demonstrate this, and a model is only as good as the one programing it. There is no doubt that the Earth is warming, the question is by how much, what can we do about it, and should we do anything?
From 1900-1939, the temperature began to rise dramatically, fully coming out from the Little Ice Age range. However, by the 1950s, the temperature receeded in one of the longest recorded downward swings, as human beings were using more and more fossil fuels. The winter of 1971/72 was the coldest European winter in 200 years. A new Ice Age was predicted. What was the cause of this? The North Atlantic Osciliation (NAO) (Fagan, 207-8). (
NAO Wikipedia article). In short, the NAO governs climate in the Northern Hemisphere, similarly to El Nino. The current state of the NAO, causing warm winters in North America and Europe, has remained this way since the 1960s, well outside the normal variation. Why is unknown, and no definative answer has been reached (Fagan 213).
The short answer is that we don't know how serious this warming is, which is why I call it
a religious doctrine. The effect of CO2 is widely debated, with the only agreed upon factor to warming (besides the NAO) is the sun. Solar activity is at an 8,000 year high, and this may account for at least part of the Earth's warming.
The second aspect to global warming is the politicization of science. Ignoring the media, the politicization starts with the scientists themselves. "Exsisting scientific evidence does not support the call for urgent action and the conventional wisdom concerning climate science is based on a false notion of scientific consensus" (
Bate). Probably the easiest place to see the manipulation of data to make change appear more dramatic is historical world temperatures, as measured my thermometers,
ice cores, and tree rings.
A common presentation (
Earth Policy Institute):

Notice how this graph starts in 1880, which is a historically cold period. If the same graph shows a time begining in the year 1000, as well as showing temperature departures from the 1961-1990 average, rather than the actual temperatures, thus demonstrating the actual change in temperature over time, the change is less dramatic (
World Cimate Report):

The third aspect is what we chose to do about global warming, the most popular option by the Greens would be treaties like Kyoto. The good news is that Kyoto does work. A little. For a
huge cost:
It has become clear that Kyoto's costs are excessively high and its benefits, in terms of net climate cooling, infinitesimal. Cost estimates for the first round of Kyoto, from now till 2012, are of the order of €500-billion to €1 trillion. The proponents of Kyoto have calculated (but never published) that this will result in a net cooling of less than 0.02 (two hundredths!) degrees Celsius in 2050. This is undetectable even with the most accurate thermometers of today. Moreover, the yearly fluctuations of temperatures are a multiple of this figure.
And so, for those that choose to believe fully in global warming, and ignore any contrary arguments are subscribing to a doctrine that does not rely on concrete science, but faith in the error of human ways, and the "balance of nature," which sustained development, according to them, destroys. More on this third aspect after I finish
Hard Green.
