Sustainability and Climate Risk (SCR) — Question 53

An environmental agency for a southeast Asian nation increases funding to study historic climate change and its impacts. The agency funds a proposal for a scientific subject matter expert to conduct a large-scale study of the nation’s tree rings.
What information will this study most likely reveal?

Answer options

• A. Temperature anomalies up to 1°C
• B. Frequency of climate tipping points
• C. Temperature anomalies up to 10°C
• D. Frequency of global ice ages

Correct answer: A

Explanation

The study of tree rings, known as dendrochronology, primarily reveals historical temperature changes, which can show anomalies typically within a range of 1°C. The other options, such as the frequency of climate tipping points, temperature anomalies up to 10°C, and frequency of global ice ages, are not directly derived from tree-ring analysis.
