to surface temperature increases in every continent except Antarctica
since the middle of the 20th century’. Figure 10.7 shows comparisons
of observed continental scale temperatures (Morice et al., 2012)
with CMIP5 simulations including both anthropogenic and natural
forcings (red lines) and including just natural forcings (blue lines).
Observed temperatures are largely within the range of simulations
with anthropogenic
forcings for all regions and outside the range
