A) Total Solar Irradiance (TSI)
B) Temperature Development
Two things are noteworthy:
Every time when solar activity was low, there were periods of cold weather.
Whenever the sun was strong (like in the current warm period, the Roman Warm Period and the Medieval Warm Period), there were warm periods.
Secondly, there is obviously a 1,000-year cycle with alternating hot and cold periods.

SUMMARY
The current atmospheric CO2 concentration is 390ppmv
The concentration is increasing at a rate of 2ppmv/year
A doubling of atmospheric CO2 will take 195 years
This may produce 0.0448°C of increased global warming
To prevent this 0.0448°C warming, we are denying people basic food staples which are being used as feed stocks for biofuels
To prevent this 0.0448°C warming, we are doubling our energy costs with inefficient and very expensive wind and solar power initiatives
To prevent this 0.0448°C warming, we are creating a multi-billion dollar carbon trading market which has no physical basis and will ultimately collapse undermining any economic recovery
Medieval warm period ?
This drawing of a graph in the IPCC's 1990 report shows it clearly
