PLIOMAX: Pliocene maximum sea level project
Accurate estimates of mid-Pliocene sea levels are necessary if we are to better constrain Greenland and Antarctic ice sheet stability in a warmer world. The mid-Pliocene climate optimum (3.3-2.9 Ma) provides both a natural analog and a testing ground for General Circulation Models (GCMs) used for pr...

| Summary: | Accurate estimates of mid-Pliocene sea levels are necessary if we are to better constrain Greenland and Antarctic ice sheet stability in a warmer world. The mid-Pliocene climate optimum (3.3-2.9 Ma) provides both a natural analog and a testing ground for General Circulation Models (GCMs) used for prediction of global warming. However, the value of such model experiments is governed by the quality of available paleoclimate data, and no more important metric of global climate exists than polar ice volume. Estimates of mid-Pliocene sea level range from +5m to>+40m (“+ ” represents the elevation of sea level relative to present) reflecting a huge range of uncertainty in |
