I think that you'd have to agree that :

1. Looking at the long term global temperature trend (more than 2,000 years), there doesn't seem to be anything unusual happening now.

2. High levels of carbon dioxide in the past haven't resulted in thermal runaway.

3. It does seem strange that, despite a 5% increase in CO2 in the past decade, there's been no sign of warming, and this trend is continuing.

4. The dependence of global temperature on CO2, is only a theory, and is yet to be backed up by real data.

5. The IPCC computer models have so far failed to match real data, and as such, are yet to demonstrate that they have any validity.

6. More and more scientists, some of whom were previously involved with the IPCC, are expressing doubts about the validity of anthropogenic warming.

7. All this talk about consensus is nonsense. Firstly, there is far from consensus among qualified scientists on this theory, and secondly science isn't decided by consensus. It's decided by testing theory against real data.

8. Many scientists agree that increasing CO2 could potentially result in a direct very small warming effect. However, it's what happens next that's important. The IPCC models assume that increased evaporation will result in an increase in water vapour - the major greenhouse gas - leading to more warming (forcing). They hope that it doesn't lead to increased cloud, which has the opposite effect (negative feedback). History suggests that the latter is more likely to dominate, making climate self regulating.

9 At most temperature has increased 0.7 degC over the past 160 years, with no increase in the past 10 years (not a magnitude that you'd notice). Yet, the IPCC claims global warming is happening faster than expected. Doesn't this seem somewhat illogical?

Let me know if any of the above seems incorrect.
