2. PRECARIOUS CONDITION
• Worldwide rise in temperature
•Severe weather conditions responsible
• World temperature has risen by 1.1° F (0.6° C) over the
past century
3.
4. EARTH: A HOT FURNACE
•2010 was the hottest year on record
• Average global temperature was of
14.63 degrees Celsius.
• The IPCC also predicts an increase in
average temperature between 2.5° F
(1.4° C) and 10.4° F (5.8° C) over the
next century,
• Rate of warming is
unprecedented in the last 10,000 years.
5. • The gases append to the planet's normal
greenhouse by:-
• permitting sunlight in
• but stopping some of the ensuing heat
from radiating back to space.
• The 21st century might see temperatures
rise of about 3 to 8 degrees
7. EFFECT: MELTING GLACIERS
•Increase in the worldwide
•sea level by 11 to 17 inches
(28 to 43 centimeters)
• melting ice glaciers that
threatens to swamp coastal
land areas and islands
8. EFFECT: SEVERE WEATHER
CONDITION
•Higher precipitation level
•El Nino
•Scientists Projections of
Global warming:-
9. FIGHT GLOBAL WARMING
• Efforts are being made by various nations to cut
down the rate of global warming
• The Kyoto agreement has been made between
various nations to reduce the emissions of
various green house gases
• Also many non profit organizations are working
for the cause
• Al Gore was one of the foremost U.S. politicians
is working on the hazards of global warming
10. Global Warming Skeptics
• They feel it is a good phenomena
• It will increase humidity in tropical deserts
• Higher levels of carbon dioxide in the
atmosphere will trigger plant growth.
• Earth will be a better place to live in
11. • Most of the global warming skeptics
believe that the global warming is not
actually occurring. They stress on the fact
the climatic conditions vary because of
• volcanism,
• obliquity cycle
• changes in solar output
• internal variability.
