Question

Quizplus · Accepted Answer

Photos of glaciers, while useful for observing changes in glacier size and position over time, are not a direct method for measuring historical temperatures. Other options like radioisotopes, pollen grains, air bubbles in ice cores, and tree rings provide more direct evidence of past climates and temperatures.
