The climate of a region is defined by the average temperature, humidity, wind direction and sunshine of the region.
If all this changes considerably, we may say that ‘climate change’ has occurred.
Throughout the earth’s history ,there have been changes in climate and that’s why evolution and adaptation has taken place.
So we may say that the climate of the earth is ever changing

The earth receives energy from sun mostly in visible and UV spectrum.
When this energy is gained by earth, she reradiates it back in form of IR radiation.
This IR radiation is absorbed by GHGs (as they are IR active)and is liberated back in atmosphere.
This cycle helps earth keep warm or else the average earth’s temperature would be 1celcius

Activities that generate GHGs are called sources
and those that remove them are called sinks.
When the cycle of source-sinks is
disturbed, climate change occurs.
This is caused by either internal or external
changes occurring regarding earth.
Our focus is on external changes.

CH4 is emitted on a large scale by cows and bulls which are ruminating animals. Every time, when they digest food CH4 is liberated.
It is about 70-120 kg methane in a year !! Another 15-20% of the total CH4 emissions
come from paddy fields that are flooded during sowing and maturing periods.

Nearly 90%of the paddy area is done in Asia. Large paddy plantations are existing inTamhini
ghat and in the small towns near pune.A large volume of N2O emissions has been
attributed to fertilizer application.But still, our farmers use 4 times more fertilizers
than expected.Also, N2O is 200 times more stronger GHG than
CO2.

62000 trees are cut in last 7 years in Pune (legally).
The hills in Pune-ARAI tekdi, parvati, taljai are the only carbon sinks of Pune we should try to conserve them.
Govn has allowed 40% construction on such hills. We think this should be opposed.
20% of global greenhouse gas emissions result from deforestation and degradation of forest.
![Page 10: 101 are seasons is climate of pune changing jnana probodhini prashala](https://reader033.fdocuments.us/reader033/viewer/2022052911/559f49ef1a28ab5c0b8b4754/html5/thumbnails/10.jpg)
Forests contain about 125 percent of the carbon found in the atmosphere. This carbon is stored in the form of wood and vegetation through "carbon sequestration".
Deforestation will also disturb the ‘carbon cycle’ This will again boost carbon production and the
cycle will go stronger and stronger along time.

Private As we all know, Pune has the maximum
number of two wheelers in the world.(19 lakh)So our city’s maximum source of pollution is
vehicles .On average, 0.62 lbsCO2/mile is released by
a vehicle in pune.So about 120lakh pounds of co2 & 60000
RSPM is released every day by vehicles alone.

LAXMI ROAD NO TRAFFIC SENSE
![Page 14: 101 are seasons is climate of pune changing jnana probodhini prashala](https://reader033.fdocuments.us/reader033/viewer/2022052911/559f49ef1a28ab5c0b8b4754/html5/thumbnails/14.jpg)
There are 10 power plants in or on the outskirts
of Pune.
On average,300lbs co2 is produced by those in a
day.
A study has shown that about 3030 kg rspm is
released in air by small scale power plants in a
day

According to a study, 1 degree Celsius rise in
climate of Pune will do 3-7% loss on potatoes,
soybean, mustard and WHEAT!!
By 2050, 20% loss on almost all crops is
expected in Maharashtra.
Good thing is that increase of co2 levels in
Pune(550ppm) has brought 15% increase in rice
and legumes.
![Page 17: 101 are seasons is climate of pune changing jnana probodhini prashala](https://reader033.fdocuments.us/reader033/viewer/2022052911/559f49ef1a28ab5c0b8b4754/html5/thumbnails/17.jpg)
Increased droughts and floods will affect availability of crops in future.
Animal distress due to heat .Effects on reproduction and milk quantity have occurred.
So loss of 1.5 million tons of milk is expected by 2020 in Maharashtra.
Cases of extreme rain fall have doubled in Pune in 50 years. This has affected mango market in Pune.

Vector borne diseases have increased
alarmingly in recent years as warmer
climate is suitable for mosquitoes to
survive and reproduce.
160 deaths were recorded in 10 yrs due to
malaria in Pune.
![Page 20: 101 are seasons is climate of pune changing jnana probodhini prashala](https://reader033.fdocuments.us/reader033/viewer/2022052911/559f49ef1a28ab5c0b8b4754/html5/thumbnails/20.jpg)
Pune’s biomes having short lifespan of 50 yrs
are still most vulnerable to projected climate
change.
Vetal tekdi has seen 10% loss in its forest cover
since 2000.
Good thing is increased CO2 levels have
boosted forest productivity in Maharashtra by
15%
![Page 21: 101 are seasons is climate of pune changing jnana probodhini prashala](https://reader033.fdocuments.us/reader033/viewer/2022052911/559f49ef1a28ab5c0b8b4754/html5/thumbnails/21.jpg)
15-40% of species will face extinction in India
with rise in 2 degree Celsius(50 years from now).
As we will see next by the graphs done by
ourselves, average temperatures will go
increasing.
So biomes will be disturbed greatly resulting loss
of chances of survival of species.

![Page 25: 101 are seasons is climate of pune changing jnana probodhini prashala](https://reader033.fdocuments.us/reader033/viewer/2022052911/559f49ef1a28ab5c0b8b4754/html5/thumbnails/25.jpg)
As we can see the required rainfall for Pune to
meet its needs is 1150.3mm.
Average rainfall of Pune is 798.2 mm
But this feat has never been achieved in last 50
years. So we must reconsider this issue
seriously and improve forest cover.
![Page 26: 101 are seasons is climate of pune changing jnana probodhini prashala](https://reader033.fdocuments.us/reader033/viewer/2022052911/559f49ef1a28ab5c0b8b4754/html5/thumbnails/26.jpg)
If you are idling your vehicle for more than
10sec, then you must turn the engine off as it
gives more CO2 than starting the engine.
About 80 vehicles were standing at S.P college
chowk for 90 seconds(this is done by ourself).
According to carbon footprint meter,idling vehicle
for 1 min=1mile=0.80lbs carbon
![Page 27: 101 are seasons is climate of pune changing jnana probodhini prashala](https://reader033.fdocuments.us/reader033/viewer/2022052911/559f49ef1a28ab5c0b8b4754/html5/thumbnails/27.jpg)
Reccomendations
So 96 pounds of carbon is released in just 1 chowk
of Pune in just 1 minute.
Imagine the number of such chowks in Pune and
the CO2 releasedin such chowks.
And imagine the CO2 released in 1 day.
WE JUST TURN OFF CAR AT
SIGNALS, WE MAKE A
DIFFERENCE!!!!
