Toasty coasts in high-CO2 worlds: Marine mollusks as paleo-weathermen?

Niels J. de Winter - Utrecht University

The ongoing global Climate Crisis has sparked a strong interest in climate reconstructions and models of geological periods with high atmospheric CO2 concentrations.
But how much do we really now about the dynamics of Earth’s past climate and coastal ecosystems on the human timescale?
Now that concern is rapidly rising about the catastrophic effect of extreme weather events and seasonality, especially to our sensitive and economically important coastal areas, biogenic carbonate producers like mollusks (clams and snails) rise to the occasion as ideal archives for environmental and ecosystem change at the timescale that matters: days to decades.
In this talk, I will try to answer the question: What can these beautifully preserved shells teach us about the occurrence of extreme weather and seasonality under various climate states?
