Climatic changes and impact on future
1. Climate changes and impact on future
A presentation by Dr Sudhanshu K K Mishra .
2. Major determinants of climatic
changes
• More population, more
growth
• Faster economic growth-
more industry,
transportation etc
• Old technology depends on
fossil fuel for running.
• Technological innovations
• Burning fossil fuels is
leading to global warming .
• Renewable sources like sun
,wind and water used very
little.
4. Consequences of a warmer world
Extreme temperatures
Projected change in rainfall pattern
More arid conditions leading to decreased crop and livestock production,
affecting food safety.
People unable to feed themselves –could lead to a situation of large scale
migration
The number of heavy rainfall days will increase substantially towards the end
of the 21st century. It is also predicted an increase in number of dry days over
central India, but a decrease in other parts
7. Year Season Increase in temperature, °C Change in rainfall, %
Lowest Highest Lowest Highest
2020 Rabi 1.08 1.54 -1.95 4.36
Kharif 0.87 1.12 1.81 5.10
2050 Rabi 2.54 3.18 -9.22 3.82
Kharif 1.81 2.37 7.18 10.52
2080 Rabi 4.14 6.31 -24.83 4.50
Kharif 2.91 4.62 10.10 15.18
There may be considerable impact on agricultural land use due to snow melt, availability of
irrigation, frequency and intensity of inter- and intra-seasonal droughts and floods, soil
organic matter transformations, soil erosion, decline in arable areas (due to submergence of
coastal lands), and availability of energy.
Impact of climate change
Projected change in temperature and rainfall due to global warming in different
crop seasons in 2020, 2050 and 2080s in south Asia.

9. Climate extreme events
• 2015- Hailstorm in Feb. damaging standing
wheat crop
• 2014 – unusually heavy floods in Kashmir
• 2013-heavy landslide and cloud burst in
Uttarakhand
• 2012- drought in Punjab, Haryana & Gujarat
• Cyclones of very high intensity hitting coastal
India- Neelam 2012,Phalin & Madi-2013 &
Hudhud in 2014.
10. Action plan on climate change –India
• Identified 8 national missions
• These missions identify measures which
promote our development objectives while
also co-benefits on climate change front.
• National programme on cleaning of Rivers and
treatment of industrial wastes before it
reaches the river.
• Focus on sustainable agriculture in rain fed,
dry and arid areas.
11. National missions -India
1.National solar mission 2.National mission for
enhanced energy efficiency
3.National mission on
sustainable habitat
13. National Missions -India
6.National mission for
sustainable agriculture
7. National mission for a green
India
8. National mission on strategic
knowledge for climatic change
14. • Climate change would have negative impact
on our lives, agriculture, weather forests,
oceans.
• Negative impacts can be minimized and
contained if we act together and without
delay.
• Acting now means we need an energy
“revolution”. We need to invest in energy
efficiency and renewable energy. We need
to rethink how we manage our forests,
design our cities and dispose of our waste.
16. • I greatly acknowledge the work done by
various institutions ,individuals who have
done pioneering work on climate change for
inputs contributed by them and used in the
presentation.
I thank them all.
