Alanis Morissette on Global Warming

I saw ad last night for a show called "Alanis Morissette explores the science behind Global Warming" on PBS. I will not dispute that it is not a good idea to burn fossil fuels at the rate we currently do, and that trees are good. However, the evidence for global warming is not all that sound since we have less than 100 years of temperature measurements, and about 30 years of high resolution weather data. (All those ice cores are kind of crappy science too, why? CO2 is soluble in water and the colder the water the more soluble it is. That “air that hasn’t seen the light of day 100,000 years” so is a prefect record of the ancient atmosphere, has been washed clean during all that time. If you squeeze ice hard enough it melts even if the temperature remains below the freezing point, (this is why you can skate on ice), so most of the CO2 can be removed by the water while rest of the gas remains largely unaltered.)
Determining long term weather trends with 30 years of data is just poor science (but makes great "news"), remember that between 1150 and 1460 there was a mini-ice age. This all happened before the Industrial Revolution, so we can’t really pin that on man’s interference, it just happened then, it went away. Weather is chaos at its finest, it is unpredictable more than a few days in advance, I cite hurricane landfall prediction as proof of this. The thing as the size of a Midwestern state but they can’t tell more than a few hours in advance what it will do. Sure NOAA thinks it will be a warm winter and they will probably be right because of El Nino, but if there wasn’t an obvious signal, they really would only be guessing.
Now whether or not you believe in global warming is immaterial, the question is should Alanis Morissette, be the person who interprets and reports on the evidence behind global warming? She clearly has an agenda, since on the commercial she said global warming is a fact. Now I did enjoy her album, Jagged Little Pill, it was wrought with emotion, and conveyed a rawness that spoke to her inner torment so it will surely to become a classic. However, it is equally clear that this woman doesn’t know what irony is, since everything she said was ironic wasn’t, it was tragic perhaps, but definitely not ironic. So I ask you this, is a woman who doesn’t know what irony is, qualified to interpret climatological data and draw conclusions? I think not, but I find it ironic that she (and the fine folks at PBS) thinks so, and by the way, that is a real example of irony.
