Re: Manmade CO2 significantly affecting the climate is rubbish
To NomNomNom (stupid name by the way!!)
"We find that water vapor is the dominant substance — responsible for about 50% of the absorption, with clouds responsible for about 25% — and CO2 responsible for 20% of the effect."
"http://www.giss.nasa.gov/research/briefs/schmidt_05/"
Pre-industrial times we had 280ppm of CO2, now we have roughly 390ppm. CO2 is a trace substance and we are talking Parts Per Million here, the increase of one hundred (roughly speaking) parts per million in rediculously small. I still think that the models being used to generate all this scare mongering are looking for carbon to be an issue and of course will find carbon being an issue.
"Ok, lets go back to the Ordovician Period 460 million years ago CO2 concentrations were 4400 ppm, but temperatures were the same as they are today"
"Sun was fainter back then. It should have been much colder than today. CO2 made it warmer."
"http://www.nature.com/nature/journal/v464/n7289/full/nature08955.html"
No NO no, unless you were around with a thermometer at that time measuring the surface of the sun then I suggest you cannot use that argument, no-one really knows the temperature of the sun, it is based on a model and an assumption that 100's of millions of years ago the sun will start fainter and gradually get brightter, if the sun was as faint as predicted then there would be no flowing water, but the evidence suggests there was, have you heard of the Faint Young Sun Paradox??? A paradox in this case would suggest that the model or theory does not quite work, something is missing!
"PLus, CO2 lags about 800 years behind temperature changes, CO2 is not the cause of higher temperatures its possibly the effect....!"
"Once CO2 starts rising temperature rises even more."
"The CO2 contribution from man is tiny and therefore its effect is TINY or not at all."
"Contribution from man is about 30 billion tons of CO2 a year. That's not tiny. Atmospheric increase is about 15 billion tons per year. Man's emission can more than explain that increase."
It is tiny compared to other sources, thats is undeniable!!! The net effect of CO2 and its impact on earth tempereratures is trumped up in models, which are likely to not know every factor that affects earth temperature, the models are no foolproof, possibly the best we have, but still not foolproof
"Man has caused atmospheric CO2 to increase by over 30% in the last 200 years. A 100% increase in CO2 is estimated to cause about 1.5C to 4.5C global warming. That would take Earth to the warmest it's been for millions of years."

I dont know if this site is credible, you will probably say not, firstly do you dispute the graphs and their figures? If not, then some comments from me:
There is no exponential rise or trend, in fact and I accept here that the trend on some graphs shows temperature rising, BUT, looking at some graphs they are level or slowing down in terms of trend (like I said above!!). We are actually on a downward slope for some of the graphs upto 2012, I appreciate this is not a trend, but cooling nonetheless.
If you look at the UAH Satellite Based Temp of the Lower Atmospehere it has a Sine Wave type shape and we are actually just commencing the downward slope in 2012, which looks like it could be a long term trend looking at earlier years!!
I still maintain you alarmists are making this up, looking too short term, using too many theories and models and not giving nature the chance to play out the cycles that it has performed for 1000's or millions of years!!!
