Sentences with phrase «stomata data»

Stomata data show higher readings and variability than the excessively smoothed ice core record.

Thus sorry, while stomata data give a rough idea of (local!)

I have repeatedly pointed out (in several places including WUWT) that (1) ice core data are useful because they indicate CO2 concentration and isotope - derived temperature data from the same trapped gas bubbles but (2) ice core data are NOT a direct indication of anything because (2a) different ice cores provide different indications and (2b) other proxies (e.g. stomata data) provide different indications to those of the ice cores and to each other.

Thus please don't use Jaworowski or Beck or stomata data as «proof» that the ice core data must be wrong, you make all skeptics unbelievable on points where the «consensus» is far less solid: the real effect of 2xCO2.

Stomata data show a much larger variation of CO2 in the last millenium (besides higher values in general), in part caused by the smoothing effect of relative slow closing air bubbles in ice cores...

That was the case for the 8.2 ka event (stomata data), the Taylor Dome for last millenium (temperature data not present anymore) and even during recent times: CO2 increase variations follow sea surface temperatures (El Nià ± o) superimposed over the industrial trend...

During the period 11,250 - 10,600 years BP, stomata data are average 330 ppmv, ice core data at 265 ppmv.
