We evaluate the contribution of natural variability to the modern decrease in foraminiferal δ<sup>18</sup>O by relying on a 2200-yr-long. high-resolution record of oxygen isotopic ratio from a Central Mediterranean sediment core. Pre-industrial values are used to train and test two sets of algorithms that are able to forecast the natural variability in &delta... https://www.megavitamines.shop/product-category/epilobium/
