Lesson C6 - Ocean's thermal inertia and climate regulation (advanced students)
Through a documentary analysis and an experiment, the students learn about the role of the ocean’s thermal inertia (compared to the land) in climate regulation.
The oceans absorb most of the solar radiation reaching the Earth (approximately 70% of the Earth is covered by oceans).
The oceans are an important heat sink and have already absorbed 90% of the heat from global warming.
The oceans’ capacity to absorb heat and their large thermal inertia contribute to regional and global climate regulation.
The large thermal inertia of the oceans means that they cool down slowly when cooled and warm up slowly when heated.
The oceans contribute to a mild climate – warmer winters and cooler summers – along the coastlines.
