Directions :
\nThe following five (5) items consist of two statements, Statement I and Statement II. Examine these two statements carefully and select the correct answer using the code given below.<\/p>\n

Statement I :
\n34. Global warming signifies the rise in global surface temperature.
\nStatement II :
\nThe increase of concentration of greenhouse gases in the atmosphere causes the rise in global surface temperature.<\/p>\n

\nBoth the statements are individually true and Statement II is the correct explanation of Statement I.
\n<\/section>\n
\n– Statement I: Global warming refers to the long-term increase in the average temperature of the Earth’s climate system, primarily observed as a rise in global surface temperature since the pre-industrial period.
\n– Statement II: Greenhouse gases (like carbon dioxide, methane, nitrous oxide, etc.) trap heat (infrared radiation) in the Earth’s atmosphere, creating a warming effect. An increase in the concentration of these gases enhances this trapping, leading to a rise in global surface temperature. This increase is primarily attributed to human activities.
\n<\/section>\n
\nStatement II provides the fundamental mechanism behind the phenomenon described in Statement I. The enhanced greenhouse effect caused by increased greenhouse gas concentrations is the principal driver of current global warming.
