Reading Ancient Climate Records
Explain how ice cores preserve ancient air bubbles, isotope ratios, and volcanic markers allowing reconstruction of temperature and CO2 going back 800,000 years; describe tree rings, ocean sediment cores, coral skeletons, and pollen records as additional climate proxies; explain how climate models are built and validated against the palaeoclimate record; describe the IPCC process of synthesising scientific evidence across thousands of studies to produce consensus assessments

“Can your child explain how scientists know what the climate was like 500,000 years ago — what kind of 'time capsules' exist in nature that preserve ancient air and temperature records, and how do scientists read them?”
