Studies on Impact of Climate Change
By PIB Delhi
India is a Party to the United Nations Framework Convention on Climate Change (UNFCCC). India has submitted Initial National Communication (INC) in 2004 and Second National Communication (SNC) in 2012 to the UNFCCC. As part of the National Communications, the Ministry conducted studies on impact of climate change in India which are summarized in the ‘Vulnerability Assessment and Adaptation’ chapters. For the SNC, climate change scenarios were analysed using high-resolution regional climate model. Simulations for 2020s, 2050s and 2080s indicate an all-round warming for Indian subcontinent. Impact of climate change and climate variability on the water resources are likely to affect irrigated agriculture, installed power capacity, environmental flows in the dry season and wet season.
There is paucity of data to establish direct correlation of climate change with diseases and deaths. However, reports of Intergovernmental Panel on Climate Change (IPCC), World Health Organization (WHO) and other widely available literature indicate health impacts of various climate variables including extreme weather events, air pollution, change in precipitation etc. Various climate model simulation studies also project possible linkages of climate change with frequency and intensity of weather events.
Weather extremes in India in the recent years (2014-2017), as reported under second Biennial Update Report (2018), is given below:

Apart from National Disaster Management Authority (NDMA) each State has its own State Disaster Management Authority to deal with such events.NDMA has issued several disaster specific guidelines for managing extreme weather-related disasters such as cyclones, floods and heat wave. National Disaster Management Plan (NDMP) has been formulated to assist all stakeholders including State Governments in disaster risk management of various hazards including hazards related to climate change.
Climate change is a global challenge and requires efforts by all nations based on the principle of Common but Differentiated Responsibility and Respective Capabilities. Government of India is committed towards combating climate change at the highest level through its several programs and schemes.
The National Cyclone Risk Mitigation Project (NRCMP) is under implementation in eight coastal states to mitigate the sufferings of the coastal community. Cyclone shelters and early warning system created under this project proved to be of great help during cyclones ‘Phailin’ in 2013, ‘Hud-Hud’ in 2014, ‘Titli’ in 2018 and cyclone ‘Fani’ in 2019.
Under National Monsoon Mission, the Ministry of Earth Sciences has set up state of the art dynamical prediction systems for short, medium & extended range forecasts and seasonal forecasts. This has helped to upgrade early warning system so that advance warning is available with concerned agencies to prepare themselves for mitigating adverse impacts of extreme weather events.
The Government is implementing National Action Plan on Climate Change (NAPCC) which comprises eight missions in specific areas of solar energy, energy efficiency, water, agriculture, Himalayan ecosystem, sustainable habitat, green India and strategic knowledge on climate change. NAPCC provides an overarching framework for all climate actions. Thirty three States/Union Territories (UTs) have prepared their State Action Plan on Climate Change in line with NAPCC taking into account State’s/UT’s specific issues relating to climate change. Under the Paris Agreement, India has submitted Nationally Determined Contributions (NDC) with target to reduce the emissions intensity of its Gross Domestic Product (GDP) by 33 to 35 % by 2030 from 2005 level, to achieve about 40% cumulative electric power installed capacity from non-fossil fuel based energy resources by 2030, and to create an additional carbon sink of 2.5 to 3 billion tones of CO2eq through additional forest and tree cover by 2030.
The Government is also implementing the scheme, ‘National Adaptation Fund for Climate Change’ to support adaptation measures of States/UTs in areas that are particularly vulnerable to the adverse impacts of climate change.
