Spatial and temporal patterns of indicators of climate change and variability in the Arab world in the past four decades

Spatial and temporal patterns of air temperature

Almost all areas of the Arab world (99%) show statistically significant positive monotonic trends (i.e., a general increase over time) of either maximum air temperature (Table 1; Fig. 2) or minimum air temperature (Table 2; Fig. 3). Less than 1% of the areas of the Arab world did not show statistically significant negative nor positive monotonic trends of either maximum air temperature or minimum air temperature.
