ANSWER
THE MINISTER OF STATE (INDEPENDENT CHARGE) FOR
MINISTRY OF SCIENCE AND TECHNOLOGY
AND EARTH SCIENCES
(DR. JITENDRA SINGH)
(a) Yes. The Government has noted changes in the weather cycle due to climate change. It
is documented comprehensively in the Ministry of Earth Sciences (MoES) report titled
"Assessment of Climate Change over the Indian Region". The report is available at
https://link.springer.com/book/10.1007/978-981-15-4327-2. The climate change
assessment report by the MoES has assessed the impact of climate change across the
country, covering all aspects of regional climate change, including the climatic extremes
across India. Based on available climate records, the report documents that the surface
air temperature over India has risen by about 0.7°C during 1901–2018, accompanied by
an increase in atmospheric moisture content. The sea surface temperatures in the tropical
Indian Ocean increased by about 1°C during 1951–2015. Clear signatures of human-
induced changes in climate have emerged across the Indian region on account of
anthropogenic greenhouse gases (GHGs) and aerosol forcing, as well as changes in land
use and land cover, which have contributed to an increase in climatic extremes. The
complex interactions among components of the Earth system, coupled with a warming
environment and regional anthropogenic influences, have contributed to increases in the
frequency of localized heavy rainfall events, the occurrence of droughts, and the intensity
of tropical cyclones over the past few decades. Future projections of regional climate,
performed under different climate change scenarios, to indicate robust changes in the
mean, variability, and extremes of several key climatic parameters over the Indian
subcontinent and adjoining areas (e.g., land temperature and precipitation, monsoons,
Indian Ocean temperature and sea level, tropical cyclones, Himalayan cryosphere, etc.).The India Meteorological Department (IMD) has also released a web-based "Climate
Hazard & Vulnerability Atlas of India" prepared for the 13 most hazardous
meteorological events, which cause extensive damage and economic, human, and animal
losses. The same can be accessed at
https://imdpune.gov.in/hazardatlas/abouthazard.html. This atlas helps State Government
authorities and disaster management agencies identify the hotspots and plan and take
appropriate action to tackle extreme weather events. This product helps build climate
change-resilient infrastructure. Further, IMD also studied changing rainfall patterns in
the country and extremes in the recent 30 years at different spatial scales (States and
Districts). A total of 29 reports on "Observed Rainfall Variability and Changes" for
various States/UTs were published and are publicly available.
(b) Yes. The climate change assessment report by the MoES mentioned in the reply to (a)
has assessed the adverse effects of global warming. The report documents that, amidst
global warming, the surface air temperature over India has risen by about 0.7°C from
1901–2018, and the sea surface temperatures in the tropical Indian Ocean have increased
by about 1°C from 1951 to 2015. This has led to increased monsoon variability, extremes,
etc. Regions, e.g., Central India, northern India, and the Western Himalayas, have
experienced a rise in extreme precipitation events; north and northwest India and
neighbouring Central India have experienced moderate droughts and expansion, as well
as semiarid regions, while coastal regions are at increased risk of cyclone-related
disasters. In particular, the Himalayan region has shown elevation-dependent warming,
changes in western disturbances, snowfall patterns, retreating glaciers, a rise in short-
lived precipitation extremes, etc.
(c) Yes. The climate change assessment report by MoES mentioned above also addresses
the rise in sea levels and provides insights into its potential adverse impact on coastal
States. The MoES report noted that based on published scientific studies, the sea level in
the Indian Ocean was observed to be rising at a rate of about 1.7 mm/year during the last
century (1900–2000) and even more rapidly in the north Indian Ocean at the rate of about
3.3 mm/year since 1993-2015. Research suggests that sea-level rise varies significantly
across the Indian coast. An assessment based on gridded satellite altimeter records (1993-
2020) for a few selected locations along the Indian coast is given below:
Location Trend (mm/yr)
Mumbai 4.59±0.19
Mormugao 4.30±0.17
Kochi 4.10±0.16
Chennai 4.31±0.26
Visakhapatnam 4.27±0.33
Paradip 4.43±0.36(d) Yes. The Government has taken several initiatives to protect the country from the adverse
effects of climate change and rising sea levels. The Government is undertaking several
efforts to assess and minimize the impact of climate change and rising sea levels. The
multi-faceted approach is aimed at addressing the potential impacts of climate change on
the country's weather patterns, focusing on adaptation, mitigation, and resilience-building.
Key initiatives include:
National Action Plan on Climate Change (NAPCC): Launched in 2008, it outlines
eight national missions that focus on promoting sustainable development while
addressing climate change. These include solar energy, energy efficiency,
sustainable agriculture, and water conservation missions. The NAPCC, prepared
under the guidance of the Prime Minister's Council on Climate Change, also
includes measures to assess and manage the impact of sea level rise on coastal
areas. The National Adaptation Fund for Climate Change (NAFCC) is aimed at
climate adaptation, including coastal areas. The NAFCC finances measures to
protect vulnerable coastal communities and improve their resilience to sea-level
rise. Besides, the Coastal Regulation Zone (CRZ) notifications also aim to manage
and regulate development in coastal areas. The CRZ regulations help protect
coastal ecosystems and manage the impact of human activities, thus reducing
vulnerability to rising sea levels.
State Action Plans: States have also developed their own climate action plan in
line with the NAPCC, addressing region-specific vulnerabilities such as extreme
weather events (floods, droughts) and shifting monsoon patterns.
Disaster Management and Early Warning Systems: India has strengthened disaster
preparedness through its National Disaster Management Authority (NDMA),
which works closely with the India Meteorological Department (IMD) to
minimize the impacts of extreme weather events (e.g., cyclones, heatwaves).
Climate-Resilient Agriculture: The Government has promoted climate-resilient
agricultural practices, such as drought-resistant crops, improved water
management, and changes in cropping patterns to adapt to shifting rainfall and
temperature patterns.
Renewable Energy Development: India is aggressively expanding renewable
energy sources, particularly solar and wind, to reduce greenhouse gas emissions
and transition to a low-carbon economy. The country aims to achieve 500 GW of
non-fossil fuel-based energy capacity by 2030.
Water Conservation: With increasing concerns over water scarcity, the
Government has initiated various programs like the Jal Jeevan Mission and
National Water Mission to improve water management and ensure sustainable
water use, especially in drought-prone regions.
Policy and Financial Frameworks: The Government has also integrated climate
change considerations into national policies and budgets, aligning with
international climate agreements (e.g., the Paris Agreement). This includes setting
emission reduction targets and focusing on climate financing for vulnerable
sectors.
These efforts are aimed at reducing vulnerabilities and preparing the country for
combating the diverse impacts of climate change, from altered monsoon patterns to more
frequent extreme weather events.
