Paleoclimate data are not as helpful for defining the likely rate of sea level rise in
coming decades, because there is no known case of growth of a positive (warming) climate forcing as rapid as the anthropogenic change.
Then
come the subjective interpretations of dicey
paleoclimate data from cherry - picked periods in our geological past.
I believe that this will not
come from model simulations or interpretations of reconstructed
data from selected
paleoclimate events or periods, but rather from reproducible experimentation or actual real - time physical observations.
The scientific evidence for human influence on current climate
comes from a large body of independent lines of evidence of which
paleoclimate data is but a small part.
