How do data collected from ice cores provide evidence for climate change.

Ice cores can tell scientists about temperature, precipitation, atmospheric composition, volcanic activity, and even wind patterns. The thickness of each layer allows scientists to determine how much snow fell in the area during a particular year. The weight of each year's snowfall compresses down the previous layers of snow, and after many years, all of this pressure helps to form glacial ice. ... They collect ice cores in many locations around Earth to study regional climate variability and compare and differentiate that variability from global climate signals

the answer to your question is b

not sure if this what   you'r looking for would be percent composition
