#Teach4Climate | Essential Principle 3: Life on Earth depends on, is shaped by, and affects climate. Teachers, get tips for teaching this essential climate principle. The essence of this principle is that life affects the climate system and in turn, the climate dictates where and how species can survive. Life affects the composition of the atmosphere and therefore the climate because different life forms take in and release gases like carbon dioxide, methane and oxygen at different rates. As the climate changes, species and ecosystems respond by adapting, migrating or reducing their population. Gradual shifts in the climate are easier to adapt to than abrupt swings, and this is certainly true for humans as well as other species.
