This is the
limit imposed by
albedo which can only
change so much with the current arrangement of the continents.
Ice
albedo feedback
change is mainly
limited to high latitude NH * land * during deglaciation, and its effects — though strong — are
limited compared to those of a radiative forcing over the global ocean.
Global temps vary for many reasons beyond CO2 levels including but not
limited to: planetary motion,
changes in
albedo, stratospheric aerosols, and solar variability to name a few, but the only area of genuine study by the IPCC has been rising CO2 levels.
While the local effects of ice
albedo and land elevation
change are huge (because the local forcings are huge, particularly for ice
albedo), their widescale climate effects are
limited by their location on land.
[23] Chapter 8 of AR5, referring to a seven model study, states that» There is no agreement on the sign of the temperature
change induced by anthropogenic land - use
change» and concludes that a net cooling of the surface — accounting for processes that are not
limited to the
albedo — is about as likely as not».
