No, just saying that 99.9% of the climate scientists say that it is and if you want t know why it is do a google search. I don't think unless you do some research on this area that you will accept the fact that gw is occurring and is because we are burning large amounts of fossil fuels.:icon_wink:Originally Posted by Dirtydawg
As I have already stated, I do believe that gw is occuring, and can believe that man is contributing to it. However, I'm perplexed as to why this climatologist would make such a statement that CO2 is not even a greenhouse gas when there is scientific evidence other than scientists coming to a general agreement that they will consider it a greenhouse gas. As far as asking for any information on the subject from you, I'm not very good at researching especially on the internet, so I thought you might have something in your cut and paste archive that you would share with me to save me from looking for it myself. Obviously, you don't. Apparently, you are taking the word of these scientists that CO2 is a greenhouse gas without your having to see the scientific documentation of how they arrived at that conclusion.
Well, DD, now that you put it like that, I will do some research on it report back to you in a little bit..
Thanks, salty. I need to be informed on all this so that when I run for office, I won't be caught unawares.
DD, I think this is what your are looking for. It's a bit long and detailed but gives you the historical background to the issue of global warming.

Just how did you arrive at that 99.9% number? There are lot's of bonafide climate scientists that disagree. Are you saying that they make up only 0.01%???
My math isn't that good. If you have 2000 scientists say increasing levels of CO2 are increasong our average global temperature, and you have 6 who say that it isn't what percentage do you come up with?
Ok Bill, my bad. Its 99.7% of all climate scientists.
I'm typing this real slow so you'll get it/(j.k)...straight out of the article:
These climate changes are well within natural variability and explained quite easily by changes in the sun. But there is nothing unusual going on.
Have you ever taken a stats class?
and the source for the vast majority of the CO2 increase is?
i agree 100% that we need to reduce real pollution. but fish dying has nothing to do with global warming.
Dogtor, what is unusual is the the rapid increase in the atmospheric CO2 levels. Nothing like it has happen before as far we know, at least the last 750,000 years. Mebbe in the last 10 million years but we are talking about what is going on "out of the ordinary". To say the current gw is "normal variability" is total BS.
And yes I've taken a stats class.
You know, all those coal-fired power plants around the world and all those cars burning gasoline and diesel not to mention those fertilzer plants and those petro-chemical plants and those steel plants and coke plants.
Of the 186 billion tons of CO2 that enter earth's atmosphere each year from all sources, only 6 billion tons are from human activity. Approximately 90 billion tons come from biologic activity in earth's oceans and another 90 billion tons from such sources as volcanoes and decaying land plants.
At 368 parts per million CO2 is a minor constituent of earth's atmosphere-- less than 4/100ths of 1% of all gases present. Compared to former geologic times, earth's current atmosphere is CO2- impoverished.
