`CO_2` and `H_2 O` absorbs strongly in the infrared rrgion and its presence in the atmospheere dectrases the loss fo heat form the enrth by radistiion . This global warming is called the greenhouse effect (other gases , including the oxides of nitraongen form car exhauset freons from aerosols and refrigeratirs and methane from bacteria in the soil and in the rument cows , also add to the reeenhouse effect ). The concentration fo atmospheric `CO_2` has increased by `10%` . The is rsulting in the increase in the mean temperature fo the earth by `2. 5^@ C`, varying form `2^@ C` t the equlator to `4^@ C` at the poles . This could have dramatic effects on the climate.
As a result of freenhouse effect , thers can be :
A: an increase in rate of egvaporation of water thus, untimely more rain , floodingn tec .
B: tropical storms in certain parts of the workd
C: a decrease in `pH` of the soil
D: an increase in `pH` of the soil
select correct altemate :
A. `B,C,D`
B. `A,C,D`
C. `A,B,D`
D. `A,B,C`
