Interesting - perhaps you can show me where I claimed to be a climate scientist. I'm an engineer.

The data I study on a regular basis (some monthly, some daily) are :
1. the four main temperature records - Hadley (Hadcrut), RSS, GISS and UAH.
2. Arctic and Antarctic ice area.
3. CO2 levels
4. Ocean level, particularly Fort Denison, but also globally. Fort Denison is the only one I statistically analyse myself.
5. Solar activity.

Study basically means plots, statistical analysis etc.

In addition I get a global report each day of every internet publication on global warming and climate change. I study any new technical reports that become publicly available that I believe are useful to my knowledge - obviously not all, and few in full detail due to the huge number. I'm happy to provide the links for any of this.

All this still leaves my with the questions :
1. Why do we believe computer models that have failed to match real data?
2. I can't find any evidence to support the hypothesis that increased CO2 can significantly effect our climate.
3. Looking at long term data (2,000 years up to 450,000 years) there's no evidence that our current climate trends are unusual. A lot of focus is put on the last 160 years for no good reason, other than that's the span of direct temperature measurement (sometimes called "recorded history". What specifically is unusual about our current climate that hasn't happened before many times?
