CLIMATE MODELS ARE BASED ON THE MAIN DRIVERS OF CLIMATE CHANGE


OBSERVATIONAL DATA IS DEPENDENT ON A NUMBER OF DIFFERENT SENSORS

THE DEVELOPMENT OF CLIMATE MODELS OVER THE LAST 35 YEARS


GRID-SCALE RESOLUTION IS AN IMPORTANT COMPONENT TO IMPROVED CLIMATE MODELS


THE RELATIVE IMPORTANCE OF NATURAL VARIABILITY, EMISSIONS UNCERTAINTY AND CLIMATE RESPONSE UNCERTAINTY


ESTIMATED CHANGES IN GLOBAL ANNUAL MEAN SEA LEVEL BASED ON A RANGE OF IPCC REPORTS


RCP8.5: This RCP is characterized by increasing greenhouse gas emissions over time, representative of scenarios in the literature that lead to high greenhouse gas concentration levels.

RCP6: This RCP represents a stabilization scenario where total radiative forcing is stabilized shortly after 2100, through the application of a range of technologies and strategies that reduce greenhouse gas emissions.

RCP4.5: This RCP is another stabilization scenario where total radiative forcing is stabilized shortly after 2100, without overshooting the long-run radiative forcing target level (emissions restrictions are tighter than for RCP6).

RCP2.6: This emission pathway is modeled using very low greenhouse gas concentration levels. In order to reach low radiative forcings (2.6 W/m2 by 2100), greenhouse gas emissions are reduced substantially over time.
