As Global Temperatures Continue to Rise, the Water Levels of Some

As global temperatures continue to rise, the water levels of some peatlands are expected to drop, exposing the peat to the air and causing it to decompose. Which of the following is most likely to result from this change in water levels?

A) the decomposition would cause the release of more carbon dioxide into the air, further contributing to global warming
B) the decomposition would cause the release of less carbon dioxide into the air, and have no effect on global warming
C) peatlands would become larger in size, and aid in the removal of carbon dioxide from the atmosphere
D) peatlands would become smaller in size, and aid in the removal of carbon dioxide from the atmosphere
