Air temperature increases similar to those observed aloft since 1960, amplified by associated increases in humidity, account for a significant portion of the enhanced ablation leading to this strongly negative mass balance, but the exact proportion is highly uncertain because of the short span of energy and mass balance observations.

Now since relative humidity remains roughly constant at the ocean surface and the air's capacity to hold water increases with temperature, relative humidity will actually decrease over land, particularly as one enters the continental interiors.

Low temperatures in Arizona have increased in urban areas, because of grass, trees, irrigation (anything which increases humidity and / or causes increased condensation,) asphalt, buildings, air conditioners, etc..

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

``... as the air warms there will be an increase in absolute humidity providing «a positive feedback».

Human activity has caused a significant long - term cooling trend -LRB--0.35 °C between the 1940s and 2009) and higher rainfall totals via the mechanism of «agricultural intensification» — a photosynthesis - associated increase in the air's water vapor or humidity levels due to an explosive (400 %) increase in crop production and yield since the 1940s.

Air in clouds and immediately next to the ocean surface is at or near 100 % relative humidity, so as temperatures increase the absolute humidity there also increases.

Measurement of CO2 concentration is always problematic; the «Standard Dry Air» SDA basis of measurement and comparison is at standard temperature and pressure which is a non-existent parameter; and as we are seeing, CO2 is not a well - mixed gas at all and will be defined by, amongst other variables, SH, or absolute humidity; SH can vary from 0 to 5 % by volume of atmosphere; as the SH increases, the absolute amount of other gases, including CO2, decreases; to say therefore that atmospheric concentrations of CO2 have remained stable and not been above 280ppm over the last 650my is fanciful; even if you assume past CO2 levels have not got above 280ppm the range of variation within that limit has been greater than the current increase;

The higher temperature resulted in the air holding the water vapor longer, so absolute humidity in the lower troposphere did increase, but the relative humidity decreased.
