International audience The mid-Piacenzian warm period (3.264 to3.025 Ma) is the most recent geological period with present-like atmosphericpCO2and is thus expected to have exhib-ited a warm climate similar to or warmer than the present day.On the basis of understanding that has been gathered on thec...
