(Many will consider that as evident in other situations: when a skeptic says surface or low tropopshere temperature of the last 6 years has a modest slope if any, for example, they will promptly object that such a phenmenon is common and is due to the residual natural variability hiding for some years the anthropogenic forcing.

That is because there is some internal variability in temperature, because volcanic temperature responses are not commensurate with instaneous volcanic forcings due to thermal inertia, and because earlier forcings will have more fully worked through the system than will have later forcings.

There is also a natural variability of the climate system (about a zero reference point) that produces El Nino and La Nina effects arising from changes in ocean circulation patterns that can make the global temperature increase or decrease, over and above the global warming due to CO2.

Spatial variability of the rates of sea level rise is mostly due to non-uniform changes in temperature and salinity and related to changes in the ocean circulation.

Some post-TAR studies indicate greater multi-centennial NH variability than was shown in the TAR, due to the particular proxies used and the specific statistical methods of processing and / or scaling them to represent past temperatures.

The real question is how much of the temperature change over the past million years was due to natural variability.

For the most, part this research examines rainfall or temperature variability as proxies for the kinds of longer - term chances that might occur due to climate change.

Our formula gives near the same variability of the temperature / CO2 relationship for yearly variations, but only a few ppmv increase in CO2, due to the slight (0.6 °C) rise in temperature over the last century.
