Figure 2.26: Trends in annual
mean surface water vapour pressure, 1975 to 1995, expressed as a percentage of
the 1975 to 1995 mean. Areas without dots have no data. Blue shaded areas have
nominally significant increasing trends and brown shaded areas have significant
decreasing trends, both at the 5% significance level. Biases in these data have
been little studied so the level of significance may be overstated. From New et
al. (2000).
