The increase in the global air temp
erature is an inadequate measure
of global warming, which should rather be
considered in terms of energy. The
ongoing global warming means that heat has been accumulating since 1880 in
the air, ground and water. Before expl
aining this warming by external heat
sources, the net heat emissions on Earth
must be considered. Such emissions
., the global use of fossil fuels and nuclear power, must contribute to
global warming. The aim of this study is to compare globally accumulated and
emitted heat. The heat accumulated in th
e air corresponds to 6.6% of global
warming, while the remaining heat is
stored in the ground (31.5%), melting of
ice (33.4%) and sea water (28.5%). It
was found that the net heat emissions
from 1880–2000 correspond to 74% of the accumulated heat, i.e., global warming, during the same period. The missing heat (26%) must have other
causes, e.g., the greenhouse effect, the natural va
riations in the climate and/or the underestimation of net heat emissions. Most measures that have already
been taken to combat global warming are also beneficial for the current explanation, though nuclear power is not a solution to (but part of) the problem.
