4.7.7. Relative humidity
Projections of change in relative humidity in response to climate change are presented for South Australia
in Figure 4.21. They show that average annual relative humidity is projected to decrease in the Adelaide
region from about 2050 under both high and low emissions scenarios (with 50 th percentile GCM
projections). In the worst case, relative humidity is projected to decline by over 4% of the 1980-1999
average.
