Thus the first year (s) temperature change is the most responsible for the first year (s) change in CO2 increase, but as the temperature influence is limited in time (a different, but constant temperature again gives a constant seasonal cycle, but at a different level), the next years that will not give a change in increase speed anymore.

Second, increased CO2 is changing the way that plants absorb and emit CO2, and that in turn is altering a seasonal cycle that has likely been unchanged for hundreds of millions of years.

Third, the ice core data how conclusively that, during natural climate cycling, changes in temperature precede changes in carbon dioxide by an average 800 years or so (Fischer et al, 1999; Indermuhle et al, 2000; Mudelsee, 2001; Caillon et al, 2003); similarly, temperature change precedes carbon dioxide change, in this case by five months, during annual seasonal cycling (Kuo, Lindberg and Thomson, 1990).

On a (2011) Climate Etc. post Pondering the Arctic Ocean, I interpreted the record in the context of a (qualitative) change point analysis, defined by changes in trend, mean value, amplitude of the annual cycle, and interannual variability.It looks like 2013 was another change point year, characterized by low amplitude seasonal cycle.

We also make use of two lengthy control simulations conducted with CESM1 under constant 1850 radiative conditions: a 2200 - year control run using the fully - coupled configuration (hereafter termed the «coupled control run»), and a 2600 - year control run using only the atmospheric model component coupled to the land model component from CESM1 with a specified repeating seasonal cycle of sea surface temperatures (SSTs) and sea ice conditions taken from the long - term climatology of the fully - coupled control run (hereafter termed the «atmospheric control run»).

Any change in CO2 levels should be calculated from calendar year averages or 12 month moving averages to remove the seasonal cycle.

Our own model would say between 2040 and 2060, and it is fair to say that our view is that the earlier dates - in other words, the more pessimistic outlook for the Arctic - are associated with models that we believe are more credible, in terms of their capability to reproduce the observed seasonal cycle in sea ice extent, and also the variations in sea ice from year to year.

The latter is determined as a moving average of SEVEN adjacent seasonal cycles centered on the month to be corrected, except for the first and last THREE and one - half years of the record, where the seasonal cycle has been averaged over the first and last SEVEN years, respectively.
