Lachniet noted that stalagmites record the chemical variations that are linked to climate.
Further in their Fig. 1 Courtillot et al. show geochemical data from a Central Alpine stalagmite which purports to establish a highly tight correlation between climate variations and a solar activity proxy; as Bard and Delaygue note, Courtillot and co-workers have concealed the fact that the correlation is so good precisely because the chronology of the two series being compared has been finely tuned to expressly maximize the correlation.
For Fred Singer, a climatologist at the University of Virginia and another co-author, the current warming «trend is simply part of a natural cycle of climate warming and cooling that has been seen in ice cores, deep sea sediments and stalagmites... and published in hundreds of papers in peer reviewed journals.»
