Tsushima, Y., A. Abe - Ouchi, and S. Manabe, 2005: Radiative damping of
annual variation in global

By comparing modelled and
observed changes in such indices, which include the global
mean surface
temperature, the land - ocean
temperature contrast, the
temperature contrast between the NH and SH, the
mean magnitude of the
annual cycle in
temperature over land and the
mean meridional
temperature gradient in the NH mid-latitudes, Braganza et al. (2004) estimate that anthropogenic forcing accounts for almost all of the warming
observed between 1946 and 1995 whereas warming between 1896 and 1945 is explained by a combination of anthropogenic and natural forcing and internal variability.
Correlations between median model results and

Black lines show
observed global
mean annual mean temperature from HadCRUT3, and thin coloured lines show global
mean temperature from five - member ensembles of CanESM2 forced with (a) anthropogenic and natural forcings (ALL), (b) natural forcings only (NAT), (c) greenhouse gases only (GHG), and (d) aerosols only (AER).
Such Hurst phenomena have been
observed in the stochastic processes of nature in the area of hydrology (Hurst) and also in the proxy record of

Anomalies simply take the average of the
observed temperatures (daily, monthly,
annual, max, min, or what have you), and convert them to a scale with a different zero point — a zero defined as the
mean observed temperature over some accepted calibration period.
