The physical impact of the climate crisis is impossible to ignore, but experts are becoming increasingly concerned about another consequence - the strain it is putting on people’s mental wellbeing. Even in the UK, a recent study found that people who experience extreme weather such as storms or flooding are 50% more likely to suffer from mental health problems, including stress and depression, for years afterwards. Soon after he started studying climate anxiety among young people, Dr. Patrick Kennedy- Williams, a clinical psychologist from Oxford, discovered worrying levels of environment-related stress and anxiety in children much younger than he assumed. “What I was most surprised by is how young the awareness and anxiety starts. My own daughter was just six when she came to me and said: ‘Daddy, are we winning the war against climate change?’ For Elizabeth Wathuti, a climate activist from Kenya, her experience of climate anxiety is not about the future but what is happening now. “People in African countries experience eco-anxiety differently because climate change for us is about the impacts that we are already experiencing now and the possibilities of the situation getting worse,” she said. She works with young people through the Green Generation Initiative she founded and sees the effects of eco-anxiety first-hand. A common worry she hears among students is: “We won’t die of old age, we’ll die from climate change.” Kennedy-Williams says there is no way to completely insulate young people from the reality of the climate crisis, and argues that would be counterproductive even if it were possible. Rather, parents should talk to their children about their concerns and help them feel empowered to take action, however small, that can make a difference. “Record and celebrate the changes you make. Nobody is too small. Make connections with other people and at the same time realise that you are not going to solve it on your own.” 20-year-old Clover Hogan clearly agrees with this advice. She set up Force of Nature, a project aimed at helping young people realise their potential to create change. Hogan’s group aims to target people aged 11-24 with a crash course in the climate crisis that helps them navigate their anxiety and realise their potential to get involved, take action and make a stand. “This is only the beginning,” said Hogan. “We’re going to see massive, massive widespread climate crisis in every country around the world, so it’s about developing the emotional resilience to carry on.” (Adapted from theguardian.com)
