Question 40. Which of the following best summarises the passage?
A. Earth’s climate naturally fluctuated through long-term cycles, yet modern warming is anomalous, rapid, and driven largely by anthropogenic carbon dioxide emissions.
B. Earth’s climate has always fluctuated through natural cycles, with modern warming reflecting a rapid phase shaped by both long-standing patterns and rising carbon dioxide levels.
C. Natural climate cycles historically governed temperature change, while recent warming represents an anomalous acceleration of these cycles alongside increased carbon dioxide concentrations.
D. Earth’s climate system experienced recurring natural fluctuations, and present warming combines rapid temperature rise with familiar mechanisms involving carbon dioxide.
