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

Elsewhere, the background forecast model plays a stronger role, enabling values of surface relative humidity to be derived less directly from other types of assimilated observation.

Relative humidity should be maintained at 60 % or lower at 75 °F (23.8 °C) within the conditioned spaces during cooling periods (the key is to prevent 70 % relative humidities from occurring adjacent to surfaces in order to control mold, mildew, and other biological growth).

That is what happens when oceans naturally increase their emission of energy and the response of the air is exactly the same whether the warmer ocean surface is a result of enhanced energy emission from the ocean or enhanced energy in the air from another cause such as more humidity or more CO2.

When surface temperature and humidity reach a threshold, clouds form which reduce incoming energy from the sun reaching the surface, particularly in Earth's vast oceanic tropics (where a disproportionate portion of it enters the climate system), while daily afternoon thunderstorms remove enough heat from surface areas to bring surface temperatures back into line.

In the lower atmosphere, the available data points to increasing water vapor content, but because of large variations in local humidity from day to night, from day to day, and from season to season, no - one currently knows exactly how much more water vapor is going into the air (IPCC Working Group 1 Assessment Report 4, Chapter 3, «Observations: Surface and Atmospheric Climate Change», page 273).
