Abstract
The temperature of the surface atmosphere over land
has been rising during recent decades. But surface
temperature, or, more accurately, enthalpy which can be
calculated from temperature, is only one component of the
energy content of the surface atmosphere. The other parts
include kinetic energy and latent heat. It has been
advocated in certain quarters that ignoring additional terms
somehow calls into question global surface temperature
analyses. Examination of all three of these components of
atmospheric energetics reveals a significant increase in
global surface atmospheric energy since the 1970s. Kinetic
energy has decreased but by over two orders of magnitude
less than the increases in both enthalpy and latent heat
which provide approximately equal contributions to the
global increases in heat content. Regionally, the enthalpy
or the latent heat component can dominate the change in
heat content. Although generally changes in latent heat
and enthalpy act in concert, in some regions they can have
the opposite signs.
