How do scientists use ice cores to predict the climate of Earth's past?


Select one:

They measure the amount of nitrogen released from the ice to provide evidence of how global warming has changed over time.

They use the different layers of ice to assume the change in sea level rise over time.

They use proxies such as pollen, dust, and volcanic ash within the different layers of ice to make predictions of what climate was like over time.

They measure the remains of living organisms that once lived on the ice, like penguin and polar bear bones, to infer what the climate was like in the past.
