Estimates for the magnitude of warming range between ~3 and ~12°C, depending upon the timescale considered and actual CO₂ trajectory. To better understand the likely impacts of the Anthropocene, we must examine how CO₂ and climate have varied in the past, particularly during warm periods in Earth history with CO₂ levels higher than modern. The carbon isotope fractionation of marine algae recorded in alkenone biomarkers (εp) is one of the primary tools for reconstructing past atmospheric CO₂ variations. These molecules are produced by the Noelaerhabdaceae, a family of calcifying coccolithophorid algae that has flourished in the open ocean for tens of millions of years. Recent studies have provided a deeper understanding of the complex mechanisms affecting alkenone carbon isotope fractionation, suggesting that the conventional framework for interpreting these records in terms of CO₂ may require reconsideration.”</span></p>
