300 years of sclerosponge thermometry shows global warming has exceeded 1.5 °C - Nature Climate Change

Understanding temperature change since the pre-industrial period is essential for climate action. This study uses an ocean proxy to better quantify when anthropogenic warming began and estimates that global temperatures have already increased by 1.7 °C.

    A fantastic paper. Is there a biologist here that can explain why Sr/Ca uptake is impacted by temperature? Given that ocean pH has been decreasing, what impact might that have on the calibration that was done?
