HadCM3 predicted growing season temperature variability, as measured by the annual seven-month growing season standard deviation, increases in 20 of the regions and declines in seven (not shown). Changes in winter temperature variability (annual five-month dormant season standard deviations) increases in 13 regions and declines in 14. Dormant period trends during 2000–2049 are significant for 20 of the 27 regions (western Europe stands out as not exhibiting changes in dormant period average temperatures). Average winter warming is 1.31◦C/50 yr or 0.26◦C per decade with Chianti and Barolo warming the most during the dormant period and Northern Oregon the least (not shown). Differences between the hemispheres are less during the dormant period (0.79 ◦C versus 0.89 ◦C for the Southern and Northern Hemispheres, respectively) with Barolo warming the most (1.12 ◦C) and South Africa the least (0.52 ◦C). Smaller increases are predicted for mean winter temperatures (0.87 ◦C on average, not shown) than for mean growing season temperatures.
