What To Do When Climate Change Feels Unstoppable – Clover Hogan’s TED Talk

Suffering from climate anxiety? Clover Hogan delivers this brilliant TED Talk on climate change that you’ll want to watch. Clover has experienced climate anxiety firsthand. However, she also understands the path to climate action starts with the one thing you can control: your mindset. She explains why challenging the stories that keep you feeling powerless can help you take the first step to protect the planet for generations to come.

Love, Sorrow And The Emotions That Power Climate Action – Knut Ivar Bjørlykhaug

Social worker and environmental activist Knut Ivar Bjørlykhaug delivers this inspiring TED talk on climate change. In it, Knut asks you to picture your favourite place in nature, and how would you then feel if it disappeared tomorrow? By doing so, Knut invites us to confront the deep, difficult emotions – love, sorrow and even rage – born from climate-driven ecological loss. By confronting these emotions, Knut argues we can power climate action.

Nature Is Everywhere, We Just Need To Learn To See It – Emma Marris

How do you define “nature?” Environmental writer Emma Marris argues that if we define nature as that which is untouched by humans, then we won’t have any left.

Instead, in this sustainability TED Talk, Emma urges us to consider a new definition of nature. A definition that includes not only pristine wilderness but also the untended patches of plants growing in urban spaces. In the process, Emma encourages us to bring our children out to touch and tinker with it, so that one day they might love and protect nature too.

The Most Important Thing You Can Do To Fight Climate Change: Talk About It – Katharine Hayhoe

How do you talk to someone who doesn’t believe in climate change? Climate scientist Katharine Hayhoe says it’s not by rehashing the same data and facts we’ve been discussing for years.

In this inspiring, pragmatic climate change TED Talk, Hayhoe shows how the key to having a real discussion is to connect over shared values like family and community. This can then prompt people to realise that they already care about a changing climate. “We can’t give in to despair,” she says. “We have to go out and look for the hope we need to inspire us to act. And that hope begins with a conversation, today.”

Climate Justice Can’t Happen Without Racial Justice – David Lammy

Why has there been so little mention of saving Black lives from the climate emergency? For too long, racial justice efforts have been distinguished from climate justice work, says David Lammy, Member of Parliament for Tottenham. In this powerful climate change TED talk about building a new movement to care for the planet, Lammy calls for inclusion and support of Black and minority leadership on climate issues. He also calls for a global recognition that we can’t solve climate change without racial, social and intergenerational justice. If you only watch one TED Talk today, make it this one.

Why Climate Change Is A Threat to Human Rights – Mary Robinson

Climate change is unfair. While rich countries can fight against rising oceans, poor people around the world are already having their lives upended – and their human rights threatened – by killer storms, starvation, and the loss of their own lands. In this passionate and inspiring sustainability TED Talk, the former Irish Prime Minister Mary Robinson asks us to join the movement for worldwide climate justice.

The Disarming Case To Act Right Now On Climate Change – Greta Thunberg

In this passionate call to action from November 2018, the then 16-year-old climate activist Greta Thunberg explains why, in August 2018, she walked out of school and organised a strike to raise awareness of global warming. This simple act of protesting outside the Swedish parliament grabbed the world’s attention. “The climate crisis has already been solved. We already have all the facts and solutions,” Thunberg says. “All we have to do is to wake up and change.”

The Link Between Climate Change, Health And Poverty – Cheryl Holder

For the poor and vulnerable, the health impacts of climate change are already here, says physician Cheryl Holder. Unseasonably hot temperatures, disease-carrying mosquitoes and climate gentrification threaten those with existing health conditions, while wealthier people move to higher ground. In this impassioned TED talk on climate change, Holder proposes impactful ways clinicians can protect their patients from climate-related health challenges. Holder also calls on doctors, politicians and others to build a care system that incorporates economic and social justice.

The Fastest Way To Slow Climate Change Now – Ilissa Ocko

“Cutting methane is the single fastest, most effective opportunity to reduce climate change risks in the near term,” says atmospheric scientist Ilissa Ocko. That’s because, unlike carbon dioxide, methane’s warming power doesn’t come from a gradual buildup over time. Instead, it is driven almost entirely by recent emissions. In this sustainability TED talk, Ocko identifies three main sources of methane pollution which, if addressed, could dramatically slow down the rate of global warming within years, not decades. “This is the methane moment,” Ocko says.

Climate Change Isn’t A Distant Threat – It’s Our Reality – Selina Neirok Leem

Every year, ocean levels rise and high tides flood the low-lying Marshall Islands in the Pacific, destroying homes, salinating water supplies and disrupting livelihoods. In this stirring poem and sustainability TED talk, youth climate warrior Selina Neirok Leem explains why adaptation using Indigenous solutions is the only choice for people on the front lines of climate change. “These islands are our ancestors, our predecessors, our homes,” Leem says. “We are at the risk of losing all of that for something we contributed very little to.”

How To Talk About Climate Change to Children

how to talk to kids about climate change

Talking to children about climate change can be daunting. Where to start, what to say, what to do, it can be tough figuring it all out. Here are some hints and tips from parents who have been there before, as well as some useful climate change resources for you and your kids.

In the early years, I thought I had parenting all figured out. Reusable nappies, check. Wooden toys, check. Reusable baby wipes, check. Hand-me-down baby clothes, check. What more could there be to bringing up a child in an eco-conscious way?

Then my kids started to grow up, and now I have a 10-year-old and a 6-year-old on my hands. They are influenced by what their friends are doing, what they see on TV and on social media, and more. It makes green parenting much harder than I ever could have imagined.

And then there’s the responsibility of talking to your children about big issues, such as climate change. That certainly wasn’t in any parenting manual I came across.

How To Talk To Children About Climate Change

Tips on talking to kids about climate change

It can be daunting talking to your kids about an issue as big, complicated, and scary as climate change. However, here are some tips about chatting to them about climate change at any age that will hopefully help make it less daunting for you. I’ve also got some resources for you if you feel like your climate change knowledge is lacking. And I’ve got child-centric climate change resources for your kids if they want to learn more at their own pace.

Tailor Your Approach When Chatting to Children About Climate Change

When I talk to my kids, I tailor my approach to make it age-appropriate. What I talk to my 10-year-old about climate change isn’t necessarily what I talk to my 6-year-old about.

With my 6-year-old, we chat more about nature and the environment. We chat about things that harm the environment, and positive things we can do to help the environment.

I’ve also found it’s easy to talk about changing weather patterns and how that links to climate change without it going too far over her head. More rain and more wind is an easy one to understand, that can be done without it sounding too scary.

My 10-year-old knows and understands a lot more, so we chat about more in-depth issues when she wants to. Sometimes she’ll come to us with questions about climate change, that we try to answer truthfully to the best of our knowledge.

That being said, you might be surprised what your child already knows or understands about climate change. If your kids are older, ask them what they already know. It can be a great starting point for you to chat a little more.

Make Your Daily Life A Learning Experience

You don’t have to go straight into the climate change chat head first. Instead, I started out when my kids were toddlers by always trying to make our daily life a learning experience.

It can vary depending on your life, and the things you do. How it looked for us is that I would chat to my kids on the walk to school about why walking is great for us and great for the environment. When we took the bus, train, or tram, it was a great time to chat about why public transport is better for the environment than taking the car. I got my kids to help me wash our reusable products, and I would chat about why reusable products are better for the environment than single-use.

Anything can be a learning experience or a talking point. And by giving your kids this bank of knowledge of positive changes that you can take to help the environment, can then be a useful step towards talking about some of the bigger climate change issues at a more age-appropriate time.

Focus On Action And Hope

I talked to Jen Gale, writer of the site Sustainable(ish) and author of the brilliant The Sustainable(ish) Guide to Green Parenting, about chatting to kids about climate change. One of her top recommendations that I love is focusing on action.

Jen says: “It’s very easy to get paralysed and overwhelmed. Focus on the things that you can do as a family, and especially if there’s anything that they can take ownership of at the age they are.”

Jen also recommends turning to the famous Fred Rogers quote, which says “Look for the helpers. You can always find people who are helping”. In the case of climate change, Jen recommends focusing on the positive stuff that other people are doing around the world. Jen says “there are so many amazing and inspiring stories out there to share.” Bringing hope to your climate change conversations can help kids to avoid feelings of overwhelm, and helps them focus on solutions.

Make It Clear The Grown-Ups Are Responsible

Something I am hyper-keen to instill in my children is that it isn’t kids who are responsible for taking action on climate change. Whilst the media likes to focus on young climate activists, as a parent I feel that many children unfairly take the burden when it comes to demanding action on climate change when it’s us adults that really need to step up.

I want my kids to have a childhood. So I make a point of talking to them about the adults and organisations doing great things for our planet and for people. I talk about local climate community work. And I talk to my kids about personal choices that my partner and I make – from walking and using public transport where we can, to not eating meat, to using ethical banks that don’t fund fossil fuels, and voting for parties with green policies.

Keep It Local

When talking to young children about climate change, Jen also recommends keeping things local and tangible.

Jen says “It’s hard enough for us as adults to grasp that turning our lights off might make a difference to the size of the polar ice cap, let alone for our kids. Things like litter picking are great, as it’s really easy to see both a cause and effect. You also feel like you’ve made a real difference. Dare I say it, it can also be quite fun too..!”

As a little 8 year old, litter picking was the first environmental activity I took part in. It definitely helped me establish that cause and effect that Jen talks about. This simple activity led me to want to learn more about the environment and ways to help. Being able to physically show them that other people are working towards a common goal can help give them encouragement and hope.

Alternatively, follow any local environmental charities. Then lookout for local family-friendly events that they might organise that you can take part in.

I’ve also taken my kids along to climate marches before. Something like this may or may not be suitable or accessible for you and your kids. However, I found it was a great way to tangibly demonstrate that it’s not just our family who are concerned about the climate.

Nuture A Love of Nature

Even if your kids are too young to talk to about climate change, you can help spark a love of the environment by nurturing a love of nature.

Jen says “We only protect what we love, and kids are fascinated by the world around them from a very young age. Nurture that natural curiosity. Point out nature when you see it, note the changing seasons, talk about how you can encourage more wildlife into your garden if you have one. There’s a great free app called ‘Seek’ from The WWF that allows you to take pictures of any plants, bugs, animals you see and then IDs them for you. My kids love using this.”

Watch The News

What also got me interested in all things environmental was my dad’s viewing habits. You see, whenever he was home from work, he always had the news on.

Seeing and hearing all this news from a young age really helped me connect the dots between the impacts of man and climate change.

Now, I don’t shy my kids away from the news. I find it good for them to know what’s going on in the world, within reason. They watch Newsround at school, which provides kid-centric news, without shying away from big issues. Then we chat about the news at home. Chatting about what they’ve seen on the news, helps them process what they’ve seen. And for climate change stories, it can help to discuss this further with adults rather than internalising negative emotions.

Useful Climate Change Resources For Children (And Adults!)

It can be daunting talking to kids about climate change. Especially if you don’t feel like you have the knowledge to be able to do so. Thankfully there are some really useful kids climate change resources that you can tap into, or let your kids have a look at by themselves.

Climate Change: The Facts

Whilst you certainly don’t need to have all the answers before you chat to your kids, you might find it helpful to have a little background knowledge. If you need an easy-to-understand primer about climate change, then watch David Attenborough’s Climate Change: The Facts before you talk to your kids. This is a no-nonsense guide to climate change that makes it easy to understand the causes of climate change and its impacts, as well as things we can do.

For older kids, it’s also a great introduction to climate change. My daughter watched this at 8 and it didn’t terrify her. However, I’d recommend watching it first before you decide if it’s suitable for your kids.

BBC Newsround

BBC’s Newsround has a useful short introduction to climate change that can make for a great starting point for a conversation.


For kids aged 7 to 11, the WWF has a useful and free downloadable climate change pack for teachers. You don’t have to be a teacher to download it, and it is full of useful climate change talking and learning points.

NASA’s Climate Kids

NASA has a really great website devoted to teaching kids about climate change and getting them talking. Here you’ll find games, activities, videos, and the answer to big climate change questions. From explaining what the greenhouse effect is, to how do we know the climate is changing, to the difference between weather and climate, and explaining what is climate change, it’s all here for kids to explore at their leisure.
