The correct option is D All of the above
Climate change is a serious problem in the 21st century. Increased temperature resulting from increase in concentration of greenhouse gases can lead to melting of ice and rise in sea levels which may in turn impact coastal areas and some of them may get submerged. Climate change may also lead to changes in cropping pattern and agriculture in general, natural terrestrial systems and water resources. Polluted atmosphere can have a negative impact on human health.
