Which of the following is least likely to be an effect of global warming?

Options

A. Increased frequency of huricanes
B. Loss of fertile delta region as for agriculture
C. Decreased rate of photosynthesis in vegetation
D. Shrinking of the polar ice regions

Answer

C

Explanation

Global warming is the current increase in temperature of the Earth.s surface (both land and water) as well as it.s atmosphere. Climatologists believe that it will lead to extreme weather conditions such as increase in the frequency and strength of hurricanes, increase in sea level and submergence of deltaic regions due to melting of polar ice, coupled with melting ice sheets and glaciers across Greenland, North America, South Americ, Europe and Asia. However, the gradual heating of Eath.s surface, oceans and atmosphere will not affect photosynthesis.
