The growth of plants in some Arctic lakes has increased significantly in the past 150 years. Scientists attribute this increase in plant growth to the increase in surface air temperatures on Earth, also known as global warming.

Which of the following best explains how global warming can cause an increase in plant growth in Arctic lakes?
A.
Global warming can cause droughts that limit the amount of water available to plants.
B.
Increasing air temperatures can cause Arctic lakes to remain frozen all year long.
C.
Global warming can cause a decrease in carbon dioxide needed for photosynthesis.
D.
Increasing air temperatures can cause an increase in the growing season of Arctic plants.
