2008  Diagnosis of climate models reveals that most of the
observed variability of global mean land temperature during
1880–2007 is caused by variations in global sea surface
temperatures (SSTs). Further, most of the variability in global
SSTs have themselves resulted from external radiative forcing
due to greenhouse gas, aerosol, solar and volcanic variations,
especially on multidecadal time scales. Our results indicate
that natural variations internal to the
