which one of the following describes a positive, amplifying feedback effect that is expected with climate change? group of answer choices warming causes ice sheets to melt, which exposes dark ocean surfaces, which absorb more heat. warming increases rates of plant photosynthesis, which helps to remove carbon dioxide from the atmosphere. warming allows forests to migrate further north, which helps to remove carbon dioxide from the atmosphere. warming leads to higher evaporation, which increases cloud formation, which reflects radiation back into space.
