We can all present graphs however we like to suit our desired outcomes BUT Tony, based on your comment above, if you can not even be open to the possibility (even 1 in 100) that growth in CO2 emissions from humans is partly contributing, even insignificantly, to global temperature increases please give us 100% proof that human CO2 is not contributing to climate change. Then we can dump the IPCC, ETS, etc and get on with our lives.

Show us the proof that current temperature increases can be solely explained by natural forcings?

I don't know of any rational person who believes global temperature increases are controlled by only natural forcings or by only human CO2. There are multitudes of forcings with varying contributions over various timescales (which I'm sure you are aware of). A major issue/debate as I see it is over the relative contributions of the various forcings to temperature change.
