Validating climate models with semi-quantitative rainfall reconstructions from speleothem δ⁴⁴Ca and Mg/Ca
Abstract: Speleothems are robust hydroclimate archives, but most proxies are qualitative (eg, “wetter” or “drier”), limiting their effectiveness for quantitative comparisons with climate models. Here, I use δ⁴⁴Ca and Mg/Ca—emerging […]
