Figure 2.2: Projected changes in annual mean temperature (in °C) relative to 1990
Return to the point in the document where this figure is located.
Note: For 2020-2049 (2030s) and 2070-2099 (2080s), scaled to 'lowest', 'mid-IPCC' and 'highest' cases, as described in the text. Contours are every 0.1°C for 2030s and every 0.2°C for 2080s.
Text description of figure
Projected changes in annual mean temperatures in degrees Celsius relative to 1990 over New Zealand for the 2030's (left hand diagrams) and 2080's (right hand diagrams) scaled to the "lowest" case (top panel), the "mid-IPCC" case (middle panel) and the "highest" case (bottom panel). For the 2030's the projected changes in temperature for New Zealand in (a) the "lowest" case is 0-0.25 degrees, (b) "mid-IPCC" case is 0.5-1.0 degrees and (c) "highest" case is 1.0-1.5 degrees. For the 2080's the projected changes in mean annual temperature for New Zealand in (a) the "lowest" case is 0.25-1.0 degrees, (b) "mid-IPCC" case is 1.5-3.0 degrees, and (c) "highest" case is 3.0-4.0 degrees. In both the lowest and mid-IPCC cases the largest increases in temperature in the 2080's is in the north and northeast of the North Island. Small regions in Fiordland and Southland sometimes have slightly less warming than the ranges indicated above.
