A free online course reveals the frightening reality and health dangers of climate change. But it also involves you in the solutions.

The predictions are numerous and disastrous. As the Earth warms, extreme weather is expected to increase injuries and affect mental health. The collection of greenhouse gases will likely affect our lungs. Vector-borne diseases — diseases spread by ticks and insects — will increase. A free, self-paced, massively open online course called Climate change and health exposes the frightening reality and involves the participants in the solutions.

The course was developed by Rainer Sauerborn, a public health expert and member of the Intergovernmental Panel on Climate Change (IPCC), the United Nations climate panel, with educational engineer Sophie-Hélène Goulet.

Videos, quizzes, and interactive exercises help you understand how climate change affects health, how humans might adapt to physical changes on Earth, and how you can take care of your own health while helping support the planet . It includes commentary and research from authors and IPCC experts from 10 countries.

Climate change and health is friendly and adapts at its own pace. It encourages students to reflect on their own environment and to advocate for better health for themselves and others. And while it’s possible to purchase a certificate of completion from Springer Nature, the instructional publisher that hosts the course, its evidence-based lessons are free for everyone.
