Suppose that a group of climate scientists claims that they can predict future impacts of global climate change with 98% accuracy. Why should you be skeptical of this claim?
A) They do not have reliable methods to measure this change.
B) Their predictions are based on incomplete information about species diversity and interactions of living organisms with each other and with their environments.
C) They should be focusing their predictions based only on climate change in the polar regions where the greatest effects of climate change are experienced.
D) They have not accounted for abiotic factors that affect global climate change in their predictions.
