Presumably this is in the distant, pre-industrial past. If so, what caused the warm period and, assuming sea level subsequently dropped afterwards, what caused the warm period to end? Other than human activity contributing to the current warm period, why is it different than previously?
- GrantS 11y agoThere appears to still be active research about mechanisms that explain the historical data but here's a clearly written article [1] discussing a few factors such as: variation in solar radiation due to variation in Earth's orbit, changing ocean currents which may lead to huge upwellings of carbon dioxide from previously sunken dead algae.
