Data and code from: Hindcast body temperature reveals sites of amplified thermal risk in global Coastlines

Identifying regions where organisms are most (and least) vulnerable to
climate change remains a key focus in ecological research. However,
accurately capturing the thermal stress experienced by many, if not most,
organisms is challenging because body temperature, which determines
physiological performance, is driven by multiple environmental factors. We
hindcasted hourly body temperatures of intertidal mussels globally using a
modified heat budget model and assessed thermal risks (extreme
temperatures and heatwaves) and hotspots based on body temperature.
Results indicated that 98.34% of global coastal mussel populations faced
at least one thermal risk factor. Most thermal risk metrics exhibited a
patchy, mosaic distribution. Semi-enclosed topography and western boundary
currents are thermal risk amplifiers, making organisms in these regions
more vulnerable than those in other regions of the same latitude. Our
research demonstrates the utility of hindcast body temperature in
integrating multiple thermal metrics to assess global thermal risks.
