In most cases, these range from about 2 to 4.5 C per doubled CO2 within the context of our current climate — with a most likely value between 2 and 3 C. On the other hand, chapter 9 describes attempts ranging far back into
paleoclimatology to relate forcings to temperature change, sometimes directly (with all the attendant uncertainties), and more often by adjusting
model parameters to determine the climate sensitivity ranges that allow the
models to best simulate data from the past — e.g., the Last Glacial Maximum (LGM).
Furthermore,
paleoclimatology provides data that we can use to
model and predict both current and future climate change scenarios.
