How do you feel about climate change? I’m guessing that, like most of us who take this problem seriously, you might find it worrying but try not to think about it too much. You do what you can – eat less meat, try not to fly, sign endless petitions – but try not to let it dominate your day-to-day life.

On a good day, this is how I deal with it too – doing what I can but trying not to get too freaked out. But I have to be honest, on bad days it really scares me. We are already seeing major impacts like melting glaciers, climate change-intensified hurricanes, forest fires, droughts and flooding. And unless humanity wakes up soon, we are in big trouble.

I think one of the less-reported aspects of climate change is its impact on our mental health, especially among the young. In a YouGov survey last year, one in three young people in Britain reported feeling scared (33%), sad (34%) or pessimistic (34%) about climate change, with 28% feeling ‘overwhelmed’. This breaks my heart for those young people, but it’s not surprising, because they will be most affected by climate change throughout the course of their lifetime. If you are a parent or grandparent, you may also be deeply worried about the kind of planet we will bequeath the next generation and the one after that – this is one reason why so many eco-activists are grandparents. They get it and feel compelled to act.

Reasons to be hopeful

So far, so gloomy. Which is why I am happy to tell you about the book I am currently reading, Not the End of the World: Why We Can Be the First Generation to Build a Sustainable Planet, by Hannah Ritchie. She is a data scientist at Oxford University and tells the story of feeling so freaked out as a student studying Earth Sciences, that she almost changed career. The onslaught of anxiety-provoking lectures on her course – and especially the stories about climate disasters she obsessively read in the media – were just overwhelming.

But this is a profoundly hopeful and optimistic book, because Ritchie argues that when you look at the actual data and key trends in energy use, pollution reduction, and so on, the real story is very different from the one we see in the media.

Let me be clear: Ritchie is no climate denier. She is a scientist who understands and accepts the prevailing scientific view – that climate change is real, it’s happening now, is man-made and unless we act fast to limit rising temperatures, humanity and all life on Earth is in big trouble. It’s just that she makes a compelling case that we have already made huge strides, at unprecedented speed, for example in decarbonising our energy production. In many industrialised countries we have virtually phased out the most polluting/carbon-emitting coal-fired power stations and rapidly developed green energies like solar, wind, hydroelectric and (somewhat controversially) nuclear.

Clean energy is now cheaper than its fossil-fuel alternatives and this will accelerate the more we adopt it at scale. This change is inevitable – as is the switch to electric cars/buses/trucks. As the cost of these green energies and modes of transport plummets, there is literally no reason not to make the switch, despite the increasingly devious and desperate tactics of the fossil-fuel industry. Sorry folks, this change is inevitable, whether you want it to be or not.

We have solved global problems before

Another argument I found really powerful and persuasive is that the global community has overcome two major environmental challenges before: acid rain in the 1980s and the ozone hole in the 1990s. In both cases, these were serious problems that required the global community to work together, despite resistance from the polluting industries that were causing the problems. And what led to the changes? Intense pressure from the public.

This led politicians to act, global treaties to be signed, industry to grudgingly change its polluting behaviour and, in both cases, drastic reductions in the harm to our environment. Now, climate change is a much bigger and more complex problem, but Ritchie argues – and I strongly believe – that if we all put enough pressure on our politicians, as well as using our consumer power to boycott the most climate-wrecking corporations/energy sources, we can solve this problem.

So if you or someone you love is struggling with climate anxiety, I strongly recommend you buy this book. It’s also packed with suggestions about how we, as individuals and communities, can make changes in the way we eat, shop and travel that can make a big difference. I am feeling hopeful about this problem for the first time in years, so I hope it will help you feel the same way too.

Sending you love and warm thoughts ❤️
