This Synthesis Report is based on the assessment carried out
by the three Working Groups (WGs) of the Intergovernmental Panel
on Climate Change (IPCC). It provides an integrated view of climate
change as the final part of the IPCC

ARCHI RASTOGI it is said that locusts thrive in warm weather. Folk wisdom has it that the outbreaks of the oriental migratory locust (Locusta migratoria manilensis) follow either droughts or

so far climate change study models have ignored how carbon emissions contributed to the melting of glaciers. This was not part of climate study models since reliable data on soot emissions was

Climate change is the defining human development challenge of the 21st Century. Failure to respond to that challenge will stall and then reverse international efforts to reduce poverty. The poorest countries and most vulnerable citizens will suffer the earliest and most damaging setbacks, even though they have contributed least to the problem.

Climate is a major driver of forest species distributions and the growth rate and structure of forests. Thus, climate change can potentially have significant effects on mountain forest hydrology, particularly the amount of water available downstream. However, many other factors influence forest biomass and mountain hydrology, and climate change effects cannot be viewed in isolation from previous land use histories (i.e. forest legacies), altered disturbance regimes (e.g. fire frequency, insect outbreaks, floods) and invasive species.

Data from the satellite-based Special Sensor Microwave Imager (SSM/I) show that the total atmospheric moisture content over oceans has increased by 0.41 kg/m2 per decade since 1988. Results from current climate models indicate that water vapor increases of this magnitude cannot be explained by climate noise alone. In a formal detection and attribution analysis using the pooled results from 22 different climate models, the simulated “fingerprint” pattern of anthropogenically caused changes in water vapor is identifiable with high statistical confidence in the SSM/I data.

Climate change is predicted to impact India's natural resource base, including water resources, forestry and agriculture, through changes in precipitation, temperatures, monsoon timings, and extreme events.

Mean-sea-level data from coastal tide gauges in the north Indian Ocean were used to show that low-frequency variability is consistent among the stations in the basin. Statistically significant trends obtained from records longer than 40 years yielded sea-level-rise estimates between 1.06

This paper makes a powerful case for enlightened leadership from India's political class on climate change. Calling it the challenge of a generation, it argues that climate change must be re-framed not as an agenda of fear and entitlement, but of growth and opportunity. Addressing it now could be the best means for a country like India to secure peace, development and quality of life for its billion-plus people. If India truly aspires to greatness, there could be no other issue more timely or compelling.

The two most important hydrological extremes are floods and droughts. These events pose serious hazards to human populations in many parts of the world. These water related disasters are caused because of large diversity in climate and topography of the country. Climate change in future is expected to have severe implications on river flows in South Asia including India. Global climate change is likely to result in severe droughts and floods in India, with major impacts on human health and food supplies.
