5. Is Global Warming Solar or Man-made?

The vested interests on both sides of the argument between the
``greenhouse'' party and the ``solar warming'' party are obvious.
Scientifically, the meteorologists, climatologists, and atmospheric
physicists, who were responsible for ``discovering'' the human
contribution to the terrestrial greenhouse effect, have been the most
consistent champions of its importance, while the solar physics
community, and especially those interested in solar-terrestrial
relations, have increasingly stressed the possible importance of the
long-term variations of the solar constant as the chief cause of
climate change. Both communities tend to take the change for granted,
and to neglect any purely statistical or chaotic effects which could
lead to excursions of the Earth's surface temperature during periods
of a couple of decades, without requiring a secular change either in
the solar constant or in atmospheric transparency. In addition, the
debate is conditioned by more powerful vested-interest groups. The oil
industry in all its guises would obviously like to believe, and would
like the public to believe, that greenhouse warming has been greatly
exaggerated, and exploits any genuine scientific differences to
undermine the credibility of the climatologists. Solar physics has
been losing ground steadily compared with other branches of
astrophysics during the past few decades, and many of its
practicioners have seen solar climate change as a chance to move into
an area where funding may be more assured. These aspirations are of
course legitimate, and there is indeed much work to be done in the
field,

but

one should be aware of the political background to this delicate
issue, and not fall into the trap of using possible solar warming as
an excuse for delay in reducing man-made emissions of greenhouse
gases. Whatever the magnitude of the effects of these in the long
term, there is no doubt that their concentration has increased
dramatically in the past 30 years, and that for many reasons this is
not a desirable path to follow.
