What variables besides those mentioned in this case study might scientists consider as they construct their models of climate change?

The use of computer models runs right through the heart of climate science.

From helping scientists unravel cycles of ice ages hundreds of thousands of years ago to making projections for this century or the next, models are an essential tool for understanding the Earth’s climate.

But what is a climate model? What does it look like? What does it actually do? These are all questions that anyone outside the world of climate science might reasonably ask.

Carbon Brief has spoken to a range of climate scientists in order to answer these questions and more. What follows is an in-depth Q&A on climate models and how scientists use them. You can use the links below to navigate to a specific question.

i believe the answer would be b. hope it : )
