"
Te residual variability in land-surface temperature which
remains after the volcanic and CO2 correlation is subtracted out is
observed to closely mirror and for slower changes, slightly lead
variations in the Atlantic Multidecadal Oscillation Index. Tis is
consistent with both the land and North Atlantic responding to the
same unknown process. Tat process may be partially anthropogenic
and include effects whose time evolution is not proportional to CO2.
It might also include natural processes. Our analysis does not rule
out long-term trends due to natural causes; however, since all of the
long-term (century scale) trend in temperature can be explained by
a simple response to greenhouse gas changes, there is no need to
assume other sources of long-term variation are present. If all of the
residual evolution during the last 150 years is assumed to be natural,
then it places an upper 95% confidence bound on the scale of decadal
natural variability at ± 0.17°C. Tough non-trivial, this number is
small compared to what our correlation analysis suggests may be
anthropogenic changes that occurred during the last century"
