#6 Y9 CC L2 Evidence for Climate Change

This podcast explores the diverse range and reliability of evidence supporting climate change. It investigates ice cores, which offer objective atmospheric data spanning up to 1.5 million years, though they are limited to specific polar regions. Listeners will learn how global temperature records provide objective measurements, despite early 19th-century thermometer data being less precise. The discussion contrasts scientific methods with paintings and diaries, noting they offer valuable qualitative proxy data but face risks of artistic bias. Finally, it examines Arctic sea ice positions, which have shown a 13.4% decline per decade since 1979. By evaluating these sources, the podcast highlights why understanding data reliability—how accurately it represents our real world—is essential for geographic study.Watch the full‑colour YouTube video for richer visuals, clearer explanations, and boosted Geography learning.
