b. the drastic changes in weather system
c. the occurrence of droughts on agricultural lands

plz

The answer is A. This is true because it affects the oceans and our earth is made mostly out of water so it affects a lot of people unlike the others where some places don't grow agriculture. I feel like that's he best answer I hope I helped!

Global warming is the result of increased concentrations of greenhouse gases, such as carbon dioxide (CO2), in our atmosphere. 

An increased average global temperature will have many impacts. Ice that covers polar continents, such as Antarctica or Greenland, will melt, causing sea level to rise by about 4 to 6 meters as the melted continental ice flows into the ocean. 

The correct answer would be (A).
