Table 6. A summary of projected increases in global sea surface temperature for 2020–2029 (relative to 1980 to 1999) and for 2090–2099 (relative to 1980 to 1999) from three IPCC scenarios [104]).

SRES model scenarios	B1 (°C)	A1B (°C)	A2 (°C)
2020–2099	0.8	0.9	1.1
2090–2099	2.1	3.1	3.5

The A2 and A1B scenarios for CO₂ emissions are very similar to that for observed global emissions [106] and hence were used here for the comparison in Figure 7.
