WHAT IS GLOBAL WARMING?y Global warming refers to an average increase in the Earth's
temperature, which in turn causes changes in climate. When
scientists talk about the issue of climate change, their concern isabout global warming caused by human activities. , in particular
the burning of fossil fuels and the resulting buildup of greenhouse
gases in the atmosphere, have influenced this warming trend.
y Rising in temperature.
y Greenhouse gases trap heat and light from the in the earths atmosphere

EFFECTSEFFECTS
ySunlight (shortwave radiation) passes easily through the earth's
atmosphere. Once it strikes and warms the earth's surface,
infrared radiation is given off and goes back into the atmosphere.
While some of this Infrared radiation or heat escapes into space,
most of it is absorbed or held by carbon dioxide and other greengases like water vapor, carbon dioxide, methane, nitrous oxide,
and ozone that exist in small quantities in the atmosphere.
y These gases form a `blanket' that keeps the earth an average of
33 degrees centigrade warmer.yWithout these gases the whole planet would be an icy wasteland
with an average temperature of 16 degrees centigrade below
freezing

Increase in carbon dioxide causeIncrease in carbon dioxide cause
earth to get warmerearth to get warmery CO2 contributes about 50% to the greenhouse effect
y Carbon dioxide is produced from burning wood, coal, gas, etc.
y The increase in carbon dioxide in the atmosphere is increasing the
heat being absorbed from the earth.y This trapped heat increases the
evaporation of water from the
oceans into the air to cause a greater
increase in warming of the atmosphere.
y CO2 has a forcing effect on climate.

EFFECTS OF OTHER GASESEFFECTS OF OTHER GASES
y Methane is emitted during the production and transport of coal,natural gas, and oil. decomposition of organic wastes in municipal
solid waste landfills and the raising of livestock.
y Nitrous oxide is emitted during agricultural and industrial
activities, as well as during combustion of solid waste and fossil fuels.
y Very powerful greenhouse gases that are not naturally occurring
include hydrofluorocarbons (HFCs),per fluorocarbons (PFCs), and
sulfur hexafluoride (SF6), which are generated in a variety of
industrial processes.
