Is Climate Change Impacting Your Mental Health?

What we’re now growing to understand is that this includes not just physical, but also mental health. If world governments don’t rise to the challenge, they could face a human-made mental health crisis at a very large scale.

In 2017, severe hurricanes highlighted the fact that surviving a major storm can leave people with a significant psychological legacy. In the aftermath of Hurricane Sandy, for example, people developed anxiety, PTSD and survivor’s guilt in response to living through the historic storm. Meanwhile, in Puerto Rico — which had a poor public health infrastructure before Hurricane Maria — the psychological challenges posed by survival also took a heavy toll.

When your livelihood is closely connected with the environment around you, changes to that environment can be devastating — especially when it’s also tied to your personal or cultural identity.

Even in developed nations with good infrastructure, treating people who suffer from the psychological aftermath of traumatic climate events can be challenging. In Australia, for example, farmers are reluctant…
