variations in winter temperature in the Alps

Tuning delivers a high correlation between y18O in SPA 12 and D14C (r =0.61). The maxima of d18O coincide with solar minima (Dalton, Maunder, Sporer, Wolf, as well as with minima at around AD 700, 500 and 300).

0.22permil change in d18O per each degree C change
