Hi Kars!

"The latest hyped hysteria, is the one Al Gore is promoting: Global warming.
Science shows clearly that Co2 is only a fraction of a percent of the 'greenhousgasses', though mr Gore want us to feel guilty and hand over our freedom to the state to safe us from the unavoideble doom and gloom. "
I dont't agree with you about this question. I was following this question as a high priority problem in the last 7 years. My thought was always, that increasing greenhouse effect could be a really big problem. You now, how I'm into renewable energies. This is the main reason why. Now the international science community thinks, that 1. CO2 level rise causes significant (the main) increase of greenhouse effect, 2. this CO2 level raise is due to the industry - mostly the power generation, partly other industries, and partly using our cars, ships, airplanes. What we do now is mostly: dig out the burried carbon based, fossil energy storage stuff, then burn it, and use the energy of them. While this process the CO2 gets to the atmosphere. The measured level is
far higher, than it was (according to old-old gas templates) a olong-long ago (from after the dinosaurs).
The work of CO2 is smple - increases greenhouse effect, and so raise the temperature. (changes the climate system - causes unknown storms, floods, othre unusual events /mostly these are not good/)
There are other factors lik methan (the gas). The situation is, that methan-hydrate, which is stored at the bottom of the seas, oceans, can be also released by a little rasie of the temp., so this can further boost the process.
Also changes of the climate at the trophical area can cause the rainforrsts to shrink - so the carbon stored in them could also get into the atmosphere, causing even more temperature rising.
I don't care what Bush says, I never really cared about. These are my thoughts, based on the information I got from several resources. Take in account, that I not only reads and watch the daily shows on TV and the daily papers (which can be the more easily manipulated).
Also - the groups you mention denied the whole effect, and the level of these effects until the last year! What caused them to change their mind? Easy: it is the profit. Until then it was worth to deny it, but now it is worth to say it. This is because of two reasons, I think: 1. the damage, what is caused, and what will be caused because of this effect is too high, and andangers their profit (and their power). 2. they probably invested some money into the industry, which can lower the effect (renewables), so they can make some profit even working against the global warming. May be there is a 3th factor: they somehow understood, that this could cause the total descrtuction of the systems working now (this is partly in 1).
What I think more: they didn't still realised the importance, and the level of this problem, so there will be big problems, big changes. There is not that much what we could do. I.e. I don't burn coal to heat my house, rather use gas (russian...), but making the insulation of our house, so less heating will be enough - less CO2 released - and of course cheaper.

I don't use the car that offen, rather travelling by the local train, and by bicycle (it is also a good aerob training, good for dynamics, and diving

). I try to buy things, which need less energy to produce, to transfer. I will set up a solar collector, which will give us the warm water, and later perhaps could help with the heating also. I switch off the ciomputer, when I leave the office. These are small things, but many small things are summarized...
