Oops, I meant to post that before you bigdog, but I made had a spill and had to mop the kitchen floor before my wife gets home! lol

MItch, I saw that program and was amazed that green technologies could be repressed by politics . There are legitimate concerns on both sides though . For instance , when the service guy was interviewed , it made one wonder about the fate of the spark plug manufacturer ,autoservice industry ,......
Theoretically we should see a lateral economic transfer in all sectors(manufacturing , retail ,service.....) with the introduction of these type of products.
Most people are not aware of the advances at our doorsteps . Magnetic(rare earth) motors , solar shingles , solar paint ,....all are real and ,once production is stepped up, affordable .
And if anyone believes that all electric cars are wimpy ,across town type vehicles then take a look at this beauty : http://www.teslamotors.com/
Right now they are made one at a time and cost around 100k . Imagine how affordable they would be as a production car.

Global warming refers to the average temperature of the earth as a whole. Imagine from some abstract point in space measuring the temperature of the earth as one number. Further, the warming under consideration is about 1 degree (C) per 100 years.

If you believe that the global temperature of the earth is not changing or somehow changing differently, fine. Tell us how you are measuring the global temperature of the earth and how you interpret the historical data. There is plenty of room for discussion on the topic and some very qualified individuals on all sides of the argument.

Now where did I leave that 'naner thermometer?

there are sites setup all throughout the US, EU, and Australia that measure hourly temps since the 1960's (Australia is leading the research on global warming effects on meteorology). Mauna Loa, along with temps, has been measuring daily CO2, CO, methane, & nitrous oxide readings since the 50's, much of this research is funded by the National Academy. the fact that the USDA hardiness zones have change is an indication that warming is occuring, Massachesetts used to be a zone 5 in the 60's and is now a zone 6 and the growing season in New England is 8 days longer.

Richard

Harvey, you are not understanding the meaning of "global temperature of the earth" as one number.

So far I have not stated here whether I agree or disagree with the projected rates of global temperature change, so please don't interpret this as an argument for or against any position. I'm just trying to clarify what the discussion is about.

No, I am understand it fine. I'm pointing out an area where it appears to be getting colder. News reports typically only give one part of the situation or, just a part of the "one" number.

As mentioned in the article, UK scientists concluded that the average global temperature has gone down since 1998. I could not find the actual report to back that up, though. Still, I think it's odd that the media doesn't report on this more. If it's a false statement, where are the numbers to back it up?

Everytime I see that the temperature has gone up one degree it makes me laugh. There is no way we have data that has a resolution of one degree.

Richard

The researchers in this field are modeling, not measuring. Last I read, there are 5 models that are under serious discussion. Further, they are not concerned with a one-time temperature change but average temperatures at 100 year intervals over several millennia, and in some cases epochs. Whether or not some or any of these models are valid is also a matter of serious discussion in the research literature.

They don't have the capibilty to model to one degree. I ran a thermo lab in college and we didn't have the capibility with very simple experiments.

Richard

I don't know whether they do or not. I do know you are pursuing a different question. These are mathematical models implemented in software. Suppose you have modeled that in the millinium 2000 B.C.E. the temperature was 65 F +/- 5 F error. In the same model, suppose you have modeled the temperature as 75 F +/- 5 F error for the millinium that just ended. Then, on average you have 0.5 F rise per century in the intervening years.
