Recent research by Henrik Svensmark and his group at the Danish National
Space Center points to the real cause of the recent warming trend. In a
series of experiments on the formation of clouds, these scientists have
shown that fluctuations in the Sun's output cause the observed changes in the
Earth's temperature.
In the past, scientists believed the fluctuations in the Sun's output were
too small to cause the observed amount of temperature change, hence the need
to look for other causes like carbon dioxide. However, these new
experiments show that fluctuations in the Sun's output are in fact large
enough, so there is no longer a need to resort to carbon dioxide as the
cause of the recent warming trend.
The discovery of the real cause of the recent increase in the Earth's
temperature is indeed a convenient truth. It means humans are not to blame
for the increase. It also means there is absolutely nothing we can, much
less do, to correct the situation.
