march 28 2009 ,saturday-different places in thje world support earth hour ,an occassion in which the lights turned off in 1 hour ,started from 8;30 to 9;30 pm ,to reduce heat around the world .in our house ,i also did it this is the only way to help earth against global warming.

before we discuss global warming,first i’ll share you a story,about sunny.everyday sunny visits earth to give heat in every living things ,and after the day he’ll return back to the sun .but one day he’s trap in our planet  because of the green house effect.days passed by lots of sunny trap inside our planet which causes more heat in our planet.

global warming & green house effect

the story illustrates how global warming start . the earth’s atmosphere plays an important role in making the environment warm .the atmosphere allows solar radiation to pass &bring heat to the to the earth’s surface . the earth’s surface absorbs this radiant energy .much of this solar radiation bounces back to atmosphere as infrared waves .gases in the atmosphere like carbon dioxide ,methane ,nitrous oxide,hallocarbons &ozome reflect this infrared waves in this process heat is trapped.this is is now what we called green house effect .green house effect brings benefits in living things .but as years passed by,too much heat cause lots of problems .global warming is born. global warming is the process in which the world suffers from the heat &after many years that passes ,the heat increases .which can cause ice or polar regions melt . this will result on rising of sea levels.global warming started during the industrial revolution in the late 1800s in which they uses coal to multiply their production the coal releases carbon dioxide
