Tuesday:  I agree with you here.  Dan keeps harping on the fact that we can't be "100% sure"  That may be true, but the vast majority of scientist say that man made pollution is the cause of much global warming & causing the polar caps to melt.  We don't need 100% agreement to start slowing these environmental changes.  Cap & trade, which Conservatives & big industry are so afraid of, is one way to reduce this problem for our kids future.

Artful Dodger: But it's not just about carbon, there are other chemicals as well. Wasn't it 6 gases that are on the hit list. Some of them are potentially worse then CO2, considering the toxicity of them and that they are more persistent then CO2.

Though you might disagree with the boffins, you cannot deny that we are benefiting. I see now that new systems of dealing with rubbish end up in energy being produced from the waste.

.... All because we got worried over landfills.

Artful Dodger: Some are interlinked by the matter of the chemicals involved. If the use of CFC's had carried on we might end up with days where we cannot go outside due to high solar radiation.

Some of the chemicals damage both. Plain and simple. Keeping a healthy environment can lower the possible risk of our carbon footprint.

It's not rocket science to see that.

Artful Dodger: When I was at school I was told electrons went around the nucleus of an atom in nice circles.

Now thanks to quantum physics I hear that an electron's orbit is unpredictable and that the electron can be in several places at once. There was no universe in the 40's just our galaxy, nothing could escape a black hole.. now they have been found to be an essential part of a galaxies development.

Quite frankly we do not have the computing power or understanding, the monitoring equipment and enough locations to be 100% .. The science on global warming is 90% certain, but at the same time it is causing a move to an idea that such as the native Indians in the USA (as well as others) have had for a long time. We are caretakers of the world, we borrow it from our children.

Artful Dodger: I've seen 90% sure that he's the daddy. Also I remember on the Apollo missions.. there was a fair chance the astronauts would die. They still went.

Plus.. from a personal point of view (as recognised by many thinkers) you can apply a 'weight' or certainty factor to an idea or thought.

So much science and invention has come from trial and error, refining ideas as you go along. The electric bulb is such an invention... it took many attempts to find a filament that would work.

As for sats... yes they have a use, but local weather stations, buoys, ships provide much more detailed info. Perhaps it's because you can't see millimetre detail from space as far as I know.

Artful Dodger:   Nonsense.  If you saw a tornado & were 90% it would hit your house, I hope you would take precautions.
