CO2 IS a greenhouse gas. -

True on Venus where the concentrations are many magnatudes higher than on earth. We also think it has a small effect on Earth, although how much of an effect is not known entirely...Which is why we are having this argument. The only way to know for sure is to speculate of climate models with a lot of unknown variables...

Humans are releasing large amounts of CO2 -

Well I guess so... But compared to what? If there were no humans?
Seriously, how does all human releases compare to a single forest fire? Are human activities causing forest fires? Maybe...But maybe in ways that aren't what they seem...in fact, many forest fires might be caused my misguided environmental policies.

Humans are, at the same time removing sinks of CO2. -

Really? What sinks? Peat bogs? Swamps? I guess you are talking about oil deposits...Don't many of those also release methane which is another greenhouse gas? If we are removing sinks, then that process could be reversed by planting more trees...But what are these sinks? And how big are they really in relation to the size of Earth's atmosphere? Surely there are some sinks which are in fact getting smaller, but aren't there also sinks that are getting larger? How can and do we measure these sinks?

CO2 IS increasing -

True... I agree. But not much in terms of molecules per 100,000 I think we are up to something like 32-40 molecules per 100,000. Now doesn't venus have something like 80,000 molecules per 100,000 or is it 95,000 per 100,000... Either way, we are a long way from there at 32-40 per 100,000

The data also indicate that this rise is from human activity, not natural causes -

Now here I disagree slightly...but hey... I'll agree just to be agreeable...So what... We are talking a mininscual amount overall compared to Water Vapor concentrations...How many H2O molecules are in the air compared to CO2 molecules? Which do you think has a bigger Greenhouse effect? is it the H2O molecules in the air or is it the CO2 molecules? Should I feel guilty every time I go in the steam room because opening the door saturates the local atmosphere with H2O molecules?

The data also show, as is to be expected, the temperature is rising.

ok I agree over the last 100 years, the tempature is about 1 degree higher... We're not dying from that...Nor would we all die if it rose another 1-2 degrees over the next 100 years... In fact, the Earth might be a more pleasant place should that occur! But even still, why is the Ice cap in Antartica getting BIGGER if this warming is occuring which we agree that we THINK is occuring...

Can you point to even ONE time where I have posted bad science on this board? -

No I can't, but even if I could, why would I? Even if you had posted bad science in the past, We are talking about the science of global warming here, not science in general...
