do natural processes explain the warming? 'no', page-20

Butcherboy, you said:

It clearly shows solar irradiance has dropped in the last few years, completely undermining the sceptic and denialist arguments.

Actually the denialists, as well as the sceptics argument is that in the last 10 years the temperature is dropping. The Sunspot activity completely supports that!

Plus it is an 11 year cycle and does not explain the longer term warming trend.

Who says it does? Unlike the alarmists, the denialists do not have a 'tunnel' vision focused on one factor only (CO2). There are a lot of factors working together - ALL ignored by the IPCC scientists, focused only on CO2.

Above I mentioned one of them: Milankovich Cycles. They give better long term understanding of the climate. No one, unfortunately, bothers to spend money on computer modelling them, as that will not bring ETS money, just better understanding on what to expect!
