INTER-GOVERNMENTAL PANEL ON CLIMATE CHANGE
(IPCC)
Climate Change is a very complex issue: policymakers need an objective
sourceof information about the causes of Climate Change, its potential
environmental andsocioeconomic consequences and the adaptation and
mitigation options to respondto it. This is why WMO and UNEP have
established IPCC in 1988. Ministry of Environment and Forests is the
nodal agencyfrom India for the IPCC. Membership of IPCC is open to
all member countries of WMO & UNEP. The IPCC does not conduct any
research nor does it monitor climaterelated data or parameters. Its role is to
assess on a comprehensive, objective, openand transparent basis the latest
scientific, technical and socioeconomic literatureproduced worldwide rel-
evant to the understanding of the risk of human-inducedClimate Change,
its observed and projected impacts and options for adaptation andmitiga-
tion. IPCC reports should be neutral with respect to policy, although they
needto deal objectively with policy relevant scientific, technical and socio
economic factors.

CLIMATE CHANGE: INDIAN SCENARIO
13.5.1 VARIATIONS IN SURFACE TEMPERATURE
Surface air temperature for the period 1901-2000 indicated a significant
warming of 0.4 °C for 100 years. The spatial distribution of temperature
changes indicated a significant warming trend has been observed along the
west coast, central India, and interior peninsula and over north-east India.
However, cooling trend has been observed in north-west and some parts in
southern India. Season wise temperature trends indicated that maximum
increase in temperature was observed in post monsoon (0.7 °C) followed
by winter (0.67 °C) and pre monsoon (0.5 °C) and monsoon (0.3 °C).
