*The greenhouse effect

*The greenhouse effect is an effect in t

he atmosphere as a result of the presence of certain gases, called the green

house gases.

*Greenhouse gases in the atmosphere a

re similar to the glass panes of a greenhouse which trap the heat and warm t

he greenhouse

*Which gases mae up the greenhouse ga

ses!

*Carbon dio"ide, chlorofluorocarbons#C$Cs%, methane nitrous o"ide, low le&el o'

one, and water &apour mae up the gre

enhouse gases

*With the e"ception of C$Cs, most of the

greenhouse gases occur naturally. (owe

&er, all of them are also the results of h

uman acti&ities.

*Today, data collected around the world sh

ow a steady increase in the concentration

of greenhouse gases. )t the same time, there is also rapid de&elopment and industria

lisation.

**ince the beginning of the +ndustrial e&olution, atmospheric concentrations of carbo

n dio"ide ha&e increased by nearly -/, th

e concentrations of methane ha&e more th

an doubled, and the concentrations of nitrous o"ide ha&e risen by about 01/.

*)s the concentration of greenhouse gases ris

es, the greenhouse effect increases, trappingmore heat in the atmosphere and raising the

a&erage temperature on 2arth.

*This o&erall rise in the a&erage temperature

of the atmosphere is nown as global warmi

ng. The increase in atmospheric temperature

has been high enough to cause changes in th

e global climate
