With the aims of i) evaluating the scientific information related to the various
components
of
the
climate
system
that
are
changing
due
to
increasing
concentrations of greenhouse gases (GHG) that modify the Earth's radiation
balance and (ii) formulating realistic response strategies to deal with the
problem of climate change. From the beginning, the Panel is divided into three
Working Groups, each one with a mean objective. Group I assesses the available
scientific information on climate change, Group II assesses the environmental
and socioeconomic impacts of climate change and adaptation measurements,
and Group III formulates strategic responses to mitigate greenhouse gases. In
addition, the Task Force on National Greenhouse Gas Inventories (TFI) was
established to develop and define an internationally agreed methodology, and
software for calculating and reporting national GHG emissions and removals
The Intergovernmental Panel on
Climate
Change
(IPCC)
was
established jointly by the World
Meteorological
Organization
(WMO) and the United Nations
Environment Program (UNEP) in
1988,
