Final answer:
Computer models are not infallible at predicting climate change due to their simplified versions of the Earth. They are based on previous and current data but may not capture all the complexities of the climate system.
Step-by-step explanation:
Computer models are not infallible at predicting climate change because they use simplified versions of the Earth to create the model. These models are based on previous and current data such as dimensions and locations of glaciers, water levels in lakes, rivers, and oceans, and changes in Earth’s orbit around the sun and the activity of the sun itself. While computer models can provide valuable insights, they are limited by the simplifications made in the modeling process, which may not fully capture all the complexities of the Earth's climate system.
