Key points:
- Paleo proxies (short for paleoclimate or paleoenvironmental proxies) are tools scientists use to recreate past climate and environmental conditions.
- These indicators or records help researchers understand historical climate variations and long-term trends since direct measurements from the distant past are impossible.
- They provide invaluable insights into Earth’s climatic history and how it has evolved over time.
- These tools have limitations, with some proxies only capturing temperature changes over long timescales, and global temperature claims may lack precision.
Why in news?
- The recent claim that July 2023 included the warmest day in more than 100,000 years is unsupported by science.
