In this context, "work out" means to solve, figure out, or calculate something. The speaker has used this expression to mean that climate scientists look at long trends to "work out" (solve, figure out) how the climate is changing. Ex: I'm good at math. I can work out equations in my head. Ex: How did you work out 15 for that question? The answer is 3000.
