In the most recent assessment undertaken by the
Intergovernmental Panel on Climate Change (IPCC) a
number of conclusions concerning global climate change
were reached, including the following: “that the increasing
body of observations gives a collective picture of a
warming world and other changes in the climate system”
and that “there is new and stronger evidence that most of
the warming observed over the last 50 years is attributable
to human activities” (IPCC, 2001).
