If the temperature of the earth keeps increasing due to the burning of fossil fuels and all other reasons that cause Global Warming, then what all can happen to the earth? Statement A: Changes in weather.

Statement B: Melting of all the glaciers into water. This will cause an increase in the sea level and widespread decrease in the snow and ice.

Statement C: Afforestation. Required to answer. Single choice.

Statements A and B.

Explanation:

Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect" — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change. Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as "feedbacks."

what's the question?

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
