Although there is still some disagreement in the preliminary results (eg the description of polar ice caps), a lot of things appear to be quite robust as the climate models for instance indicate consistent patterns of surface warming and rainfall trends: the models tend to agree on a stronger warming in the Arctic and stronger precipitation changes in the Topics (see crude examples for the SRES A1b scenarios given in Figures 1 & 2; Note, the degrees of freedom varies with latitude, so that the uncertainty of these estimates are greater near the poles).

Further, precipitation over land is a small fraction of the total, so there's a lot of room for changes in precip there without altering the result on the global mean.

Changes in aridity — the ratio between evaporation and precipitation — are expected in many regions as a result of climate change.

New research by Robert Allen, a climatologist at the University of California, Riverside, suggests that climate change may actually result in more precipitation — and more floods and storms.10 months ago

For instance, Milly et al., 2003 (Open access) used computer simulations and results from the CMAP reanalysis of precipitation levels to calculate that climate - related changes in water storage on land were causing a sea - level rise of about 0.12 mm / year in the period 1981 - 1998 (although, they admitted they couldn't calculate an error bar for that estimate).

sensitivity the degree to which a system will respond to a change in climatic conditions (e.g., the extent of change in ecosystem composition, structure and functioning, including net primary productivity, resulting from a given change in temperature or precipitation)

Even in areas where precipitation does not decrease, these increases in surface evaporation and loss of water from plants lead to more rapid drying of soils if the effects of higher temperatures are not offset by other changes (such as reduced wind speed or increased humidity).5 As soil dries out, a larger proportion of the incoming heat from the sun goes into heating the soil and adjacent air rather than evaporating its moisture, resulting in hotter summers under drier climatic conditions.6

Importantly, the changes in cereal yield projected for the 2020s and 2080s are driven by GHG - induced climate change and likely do not fully capture interannual precipitation variability which can result in large yield reductions during dry periods, as the IPCC (Christensen et al., 2007) states: ``... there is less confidence in the ability of the AOGCMs (atmosphere - ocean general circulation models) to generate interannual variability in the SSTs (sea surface temperatures) of the type known to affect African rainfall, as evidenced by the fact that very few AOGCMs produce droughts comparable in magnitude to the Sahel droughts of the 1970s and 1980s.»

I conclude that the observed global aridity changes up to 2010 are consistent with model predictions, which suggest severe and widespread droughts in the next 30 — 90 years over many land areas resulting from either decreased precipitation and / or increased evaporation.

«Climate change» is a broader term that includes many other impacts resulting from global warming (for example., changes in precipitation and ocean acidity) and different geographic scales (for example, a continent, an ocean, a hemisphere, the planet).

In other words, if these yield reductions resulting from greenhouse gas — induced climate change were superimposed on the yield reductions that might occur during a particularly dry period arising from the region's characteristic precipitation variability, they would be higher and comparable with the results from the Morocco National Communication.
