Abstract: This paper contributes to the debate on the proximate
causes of climate change. Also, it discusses the impact of the global
temperature increases since the beginning of the twentieth century
and the effectiveness of climate change models in isolating the
primary cause (anthropogenic influences or natural variability in
temperature) of the observed temperature increases that occurred
within this period. The paper argues that if climate scientist and
policymakers ignore the anthropogenic influence (greenhouse gases)
on global warming on the pretense of lack of agreement among
various climate models and their inability to account for all the
necessary factors of global warming at all levels the current efforts of
greenhouse emissions control and global warming as a whole could
be exacerbated.
