Students often underestimate Global Change because it appears early in the syllabus, but AP questions here test application, not memorized definitions alone.
Large-scale environmental changes including climate change, ozone depletion, invasive species, and mitigation/adaptation. On the AP Environmental Science exam, items from Global Change often ask you to apply course concepts to a scenario you have not memorized verbatim rather than recall isolated terms.
College Board topic statements for this unit include Climate change science, greenhouse gases, mitigation and adaptation; and Ozone depletion, ocean acidification, invasive species and global impacts.
On the AP Environmental Science exam, Global Change is weighted at roughly 15%–20% of the multiple-choice section. That is enough to matter on score day even if your class spent only a few weeks here—especially when questions combine this unit with later material.
Time pressure makes Global Change tempting to rush—especially when numbers or dates appear in every option. Slow down enough to identify what the question is actually asking before eliminating distractors.
Try explaining this unit's core idea to someone else in under 60 seconds. If the explanation drifts, you found a gap worth fixing before test day.
