Narrowly scoped, the present situation is either strictly caused by solar variations (in which case I believe the «solar variation» crowd will inappropriately gain credibility over the next 10 to 20 years as we work through the next below
average solar cycle or two), or strictly caused by CO2 concentrations (in which case I believe the «CO2 concentrations» crowd will inappropriately lose credibility as the non-linear relationship (sensitivity is
based on doublings, not linear increases) between increased CO2 concentrations, and forecasts for below
average solar cycles reduces the longer term upward trend in
global temperatures).
As far as this historic period is concerned, the reconstruction of past temperatures
based on deep boreholes in deep permafrost is one of the best past temperature proxies we have (for the
global regions with permafrost — polar regions and mountainous regions)-- as a signal of
average temperatures it's even more accurate than historic direct measurements of the air temperature, since the earth's upper crust acts as a near perfect conservator of past temperatures — given that no water circulation takes place, which is precisely the case in permafrost where by definition the water is frozen.
