Temperature

Here is a plot of Temperature data from Hadcrut3 since 2000. Nothing remarkable for the last 14 years.

What drives temperature change? Surprisingly, not CO2, whatsoever. The following is a summary of the major drivers and their relative strengths. Because our temperature record is so short (1880-present) the deVries and Oceanic oscillations dominate our concerns. You would have to go to longer temperature records to see the longer solar and orbital cycles that dominate the glacial cycles.

Another example of the same result but showing the authors.

Here is a great graph that superimposes the orbital forcings and eccentricity, together with Ice Volume, Temperature and CO levels.

A few things worth noting as you study this graph. Notice how much ice there usually is. Those interglacials seem so small and short lived.
