This is based on the ice core record, but there are other measures of CO2 that strongly disagree with the ice core record: for example, the leaf stomata record generated by Wagner et al shows significant variation in the Holocene period, indicating that rapid fluctuations do occur and that 370ppm is «high» but not outside typical variability.

However, Solanki et al made the same point as we do: «This comparison shows without requiring any recourse to modeling that since roughly 1970 the solar influence on climate (through the channels considered here) can not have been dominant» (Solanki et al., 2003), and: «Although the rarity of the current episode of high average sunspot numbers may indicate that the Sun has contributed to the unusual climate change during the twentieth century, we point out that solar variability is unlikely to have been the dominant cause of the strong warming during the past three decades.»

The very high significance levels of model — observation discrepancies in LT and MT trends that were obtained in some studies (e.g., Douglass et al., 2008; McKitrick et al., 2010) thus arose to a substantial degree from using the standard error of the model ensemble mean as a measure of uncertainty, instead of the ensemble standard deviation or some other appropriate measure for uncertainty arising from internal climate variability... Nevertheless, almost all model ensemble members show a warming trend in both LT and MT larger than observational estimates (McKitrick et al., 2010; Po - Chedley and Fu, 2012; Santer et al., 2013).
