Impact of Climate Change on India
India’s high population density, large spatial and temporal variability in rainfall and high poverty rates make it particularly vulnerable to the impacts of climate change. This chapter provides a baseline of knowledge on evidence and impacts. More frequent episodes of extreme rainfall, longer dry spells, higher sea levels and more heat waves are expected. This will have unpredictable impacts on agriculture and public health. There has been an increase in the national mean surface air temperature and the number of hot days, significant regional variations in rainfall patterns, measurable melting of Himalayan glaciers and a rise in sea-level on both the country’s coasts. High levels of air pollution could exacerbate changes in rainfall patterns. India will need better climate models to predict impacts by state and region, a pre-requisite for informed adaptation policy.
