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
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.
• The gases append to the planets 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
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
EFFECT: SEVERE WEATHER CONDITION •Higher precipitation level •El Nino •Scientists Projections of Global warming:-
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
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
• 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.
