Learn what climate change is, and how it affects the planet

Climate Change poses an increasing threat to the stability of Earth’s systems. If we want to protect our planet from dangerous and unprecedented change, first we must understand the science behind climate change.

On this course you will explore this science, looking back across 4 billion years of Earth’s history to help you learn the difference between ‘natural’ from ‘human’ induced change; looking to the present to see how the impacts of climate change are already being felt; and finally looking to the future to see what it might hold for our planet.
