Earth's temperature

Samantha Burgess explains how researchers estimate the Earth’s temperature and monitor a changing climate. The episode examines the observations and international scientific collaboration behind global temperature records, and the work involved in assessing the planet’s changing conditions rather than treating a single local measurement as a global answer.

…of heat-trapping gases alter Earth's temperature. It addresses misconceptions about saturation and compares greenhouse forcing with other natural and human influences on the planetary energy balance. Measurements provide a basis for evaluating their relative contributions.
