The following are my references that give me a data base of global climate patterns.
In
the chart above, the bottom graph shows oscillations in global climate
over the past million years, based on an Antarctic ice core sample
called Vostok that measured 750,000 years.
The first four graphs, above, show orbital oscillations of the planet earth as it circles the sun. The length of each cycle is identified under the type of orbital change labeled on the right hand side: for example, the obliqueness of the earth orbit results in a 41,000 year cycle. The cycles referred to in "Solar Forcing" have to do with differential heating of the earth related to the greater water volume in the Southern Hemisphere and the greater land mass in the Northern.
Using the first four charts, an exact equation predicts the fifth chart of actual earth climate changes. Our climate on earth is dictated directly by our orbit around the sun. Our orbit is an exact and unchanging reality of physics and planetary dynamics.

This image directly above left shows the instrumental record of global average temperatures as compiled by the Climatic Research Unit of the University of East Anglia and the Hadley Centre of the UK Meteorological Office. Data set HadCRUT3
For the past century there have been three periods of global temperature increase with a decrease in between.
The chart on the upper right shows the CO2 concentration in the atmosphere for the same period. Correlation is very poor. Remember that CO2 in the atmosphere is 3 tenths of one percent. Oxygen is 21% of the atmosphere.
The solar wind and solar 10Be measurements shown below on the right are a very good correlation to recent global climate.

The chart above left, shows the most recent global warming period with a peak in 1998. The actual numbers shown below confirm this peak. Listed are month by month global surface temperature since 1995: Here we are talking about a half degree centigrade warming since 1940.

Each number is the centigrade difference from the 1940 temperature base. Each month is shown with the last number, in bold, the average for the year.
