Climate Change Issues

Global WarmingGlobal Warming
Global warming is the increase in the average
measured temperature of the Earth's near-
surface air and oceans since the mid-20th
century, and its projected continuation.
The average global air temperature near the
Earth's surface increased 0.74 ± 0.18 °C (1.33 ±
0.32 °F) during the 100 years ending in 2005.

The 2007 rise in global carbon dioxide (CO2) concentrations is tied with 2005 as
the third highest since atmospheric measurements began in 1958. The red line
shows the trend together with seasonal variations. The black line indicates the
trend that emerges when the seasonal cycle has been removed. (Credit: NOAA)

Rajasthan- Drought
Rann of Kutch – sea level rise
Mumbai-Salt water intrusion
Kerala –Productivity of Forest
Tamil Nadu-Coral bleaching
Ganges – Sedimentation problem
Sunderbans-Sea level raise
Northwest India-reduction In rice yield
EffectEffect on apple cultivationon apple cultivation
Kullu Valley, Himachal Pradesh
Experienced a number of crop failures in the
last 15 years
Apple belt has moved 30 kilometers
[northwards] over the last 50 years
Apple growers, says attributed poor
production to reduced snowfall and its
changed timing.
Case study:1 Impact on Agriculture

• Shift in Agriculture
• Apple cultivation is affected in Kullu Valley
• Apple belt has moved 30 KM nothwards
• Forest resources were removed
2. Ganga under threat from warming2. Ganga under threat from warming
Himalayan source of the Ganga is drying up
at a rate of 40 yards a year, nearly twice as
fast as two decades ago, and that some of
these glaciers might disappear by 2030.
In the dry summer months, the Gangotri
glacier provides up to 70 percent of the
water of the Ganga.
According to a UN climate report, the
shrinking glaciers also threaten Asia’s supply
of fresh water.

3. Impact on Coastal Orissa3. Impact on Coastal Orissa
•The Satavaya region, once a cluster of seven
villages.
•Only two out of the seven villages exists the other
five villages have been submerged.
•The Coastal villages have been affected by cyclone
and floods killing more than 30,000 people.
•The sea has ingressed to about 1.5 km into
Satavaya and 2.5 km into Kanakpur. Satavaya has
also lost 56% of its mangrove vegetation.
Global ImpactsGlobal Impacts
The largest glacier on Mount Kenya has
lost 92% of its mass
Sea levels have risen by 10 - 25 cm
The thickness of sea ice in the arctic has
decreased by 40%.
The Common Murre has advanced
breeding by 24 days per decade over the
past 50 years in response to higher
temperatures.
The Baltimore oriole is shifting northward
and may soon disappear entirely from the
Baltimore area.
Polar bear populations are coming under
threat as food becomes harder to hunt.

Signed UNFCC on 10th
June 1992
India ratified the Kyoto protocol
India has a National Action Plan on Climate
Change

◦ National Mission for Enhanced Energy Efficiency
◦ National Mission on Sustainable Habitat
◦ National Water Mission
◦ National Mission for Sustaining the Himalayan Ecosystem
◦ National Mission for a “ Green India”
◦ National Mission for Sustainable Agriculture
◦ National Mission on Strategic Mission on Climate Change

India has a well developed policy, legislative

The impacts of climate change are not evenly distributed – the
poorest countries and people will suffer earliest and most. And if
and when the damages appear it will be too late to reverse the
process. Thus we are forced to look a long way ahead.
