2. Definition
Global warming usually means a fast, unnatural
increase in overall temperature of earth that is
enough to cause the expected climate conditions to
change rapidly.
4. Causes for Global Warming
Rise in CO2 emission.
Rise in other green house gases, like methane, Water
vapor.
Deforestation- burning and cutting millions of acres of trees each
year, it is responsible for 20-25 per cent of all carbon emissions.
Energy use and production- More than 80% of the world-
wide energy demand is currently supplied by the fossil fuels coal, oil
or gas.
The true cause of global warming is our
thoughtless attitude towords Nature.
6. Relation between Temperature
and CO2
Today's 370 parts per million of CO2 is the greatest in 20 million years --
and it is still going up.

8. A Pentagan Report points to possible "catastrophic droughts, famines and riots,
with skirmishes over food and water, mass migration and economic disruption.
Starvation and disease will decrease population size".
The Stern Report says "climate change will affect the basic elements of life (water,
food production, health and the environment). Hundreds of millions of people could
be affected by coastal flooding".
9. Impact of Global Warming
Ice Under Fire: Arctic
40% REDUCED IN 40 YEARS
NEXT 30 YEARS IT WILL BE
COMPLETELY GONE IN
SUMMER TIME.
10. First, it will raise sea levels.
Second, Ice caps are white, and reflect sunlight,
much of which is reflected back into space, further
cooling Earth.
Third, melting ice caps will throw the global
ecosystem out of balance. The ice caps are fresh
water, and when they melt they will desalinate the
ocean, or in plain English - make it less salty.
Fourth, temperature rises and changing landscapes
in the arctic circle will endanger several species of
animals. Only the most adaptable will survive.
12. ANTARCTICA- LARGEST ICE SHELVES IN THE
WORLD.
About 98% of Antarctica is covered
by ice, which averages at least 1.6
kilometres (1.0 mi) in thickness.
Permafrost
Permafrost is a solid structure of
frozen soil, extending to depths of
2.200 feet in some areas of the arctic
and subarctic regions, containing
grasses, roots, sticks, much of it
dating back to 30,000 years.
13. The Larsen B sector collapsed and broke up, 3,250 km² of ice 220 m thick
disintegrated in just 35 DAYS. "hotspot of global warming."
14. GREENLAND MELTING
The rate of ice-mass loss from an island in
Greenland increased by 250 percent
during a period spanning May 2004 to
April 2006 relative to the period from April
2002 to April 2004,a study concludes.
IF ENTIRE GREENLAND OR WEST
ANTARCTICA MELTS SEA LEVEL RISE 20
FEET Worldwide!

CHOOYU GLACIER POR TAGE GLACIER 2004
18. Rongbuk Glacier - Northern slope of Mount Everest
IF GLOBAL WARMING CONTINUES AT THIS
RATE RIVER GANGA WILL BECOME SEASONAL
IN 35 YEARS!!!
19. Warming Winds, Rising Tides:
Oceans
Coral reefs are probably
the most complex
ecosystems on the planet,
home to hundreds of
thousands of species.
High water temperatures
caused coral bleaching and
subsequent death or
adverse change to sixteen
percent of world reefs
overall and up to 46
percent in parts of the
Indian Ocean.
Aquatic Life Dependent
On Them are Dying.
20. OCEAN TEMPERATURE RISE IMPACTS:
STRONGER STORMS, TORNADOES, HURRICANS
HURRICANE KATRINA –AUGUST 29,2005
INCREASE IN PRECIPITATION – RELOCATED.
MUMBAI FLOODS, 26 JULY 2005
37 inches of rain in 24 hrs
Water levels reached 7 ft.
MORE WATER EVAPORATION IN OCEAN, LANDS
SUCKED UP- SEVER DROUGHTS
WIND AND WATER CYCLES CHANGE
21. Pushing the Boundaries of Life:
Temperate Zone
"We are running into a really
serious loss of biodiversity."
2/3 of butterfly species with long
observational records had shifted
northward by from 22 to 150
miles, consistent with
temperature increases in Europe.
22. SOLUTIONS
The Most Important Things You Can Do about
Rapid Climate Change:
1. Understand the Problem, its causes
2. Do Something Today to Reduce Greenhouse
Gas Emissions, find solutions.
Its time to ACT.
"In my view, climate change is the most severe
problem that we are facing today -- more serious
even than the threat of terrorism."
- David A. King, Chief Scientific Advisor to the British Government
