To estimate the significance of these processes also requires an estimate of future global warming, which in turn depends on future concentrations of "greenhouse gases and the sensitivity of the cInnate to changes in these concentrations. I,ong-term carbon clioxide monitoring stations are situated to minimize localized effects of industrialization.

Although they used a fairly sophisticated mode! for projecting global warmung and thermal expansion, they cautioned that the absence of glacial process models kept them from making accurate projections of snow and ice contributions to sea level.

Applying these values to an estimated temperature change of 3.5 ~ 2°C due to a doubling of greenhouse gases over the next century, the associated range in global mean sea level change is from 24 to 154 cm. All of the studies have focused on changes in the worId's average sea level.
