The Science of Climate Change

Climate change is no longer a distant threat or just a possibility, it is now a reality for all of us. In this pathway, Kevin Trenberth, a renowned climatologist, delves into the science behind climate change. He first introduces the climate system, its main components and forces.

Tackling the Plastic Crisis

Plastic pollution is by far the biggest threat to our oceans and this remains an incredibly tough problem to solve. Plastic credits could potentially serve as one of the much needed solutions for this crisis.

The Scale of the Net Zero Challenge

The price of meeting net zero is estimated to be between $100-150 trillion over the next 30 years. Regardless of this cost, we need to reach net zero before climate change does irreversible damage to the environment and the economy.

ESG, Sustainability and Impact Jargon Buster

ESG, sustainability, impact… they all just mean green, right? Not quite. Despite being used often interchangeably, there are distinct differences between these terms.

What if the deepest climate solution isn’t just policy or technology — but remembering who we are? In 2019, artists issued an open call to the world: share a Letter to the Earth — a poem, manifesto, message — to pause from business as usual and speak directly to the living world.

Over the years, thousands responded. Children begging for their futures. Parents pleading for forgiveness. Scientists sharing their nightmares. Leaders confronting their limitations. Activists galvanising us into action.

But through it all, a distinct message emerged - a message of remembrance. A remembering that we are connected to the Earth. That the Earth gives us life and sustains us. That the Earth is soil beneath our feet to be felt, to be tended, and to be restored. That the Earth is alive and that we are a part of it.

“I want you to respect me. I want you to embrace me. To listen.” — Mother Earth, voiced by Nemonte Nenquimo, Indigenous Waoroni activist and leader from the Ecuadorian Amazon, in her letter to camera (June 2024).

The crisis of disconnection

In our increasingly urbanised environments, it is easy to forget our inherent interconnectedness with the natural world. More than half the human population now lives in cities, and by 2050 that could rise to 70%. Meanwhile, loss of biodiversity, habitat fragmentation, and reduced access to green space mean many people scarcely experience intact nature.

“Nature connectedness is now accepted as a key root cause of the environmental crisis”, says Miles Richardson, Professor of Nature Connectedness, University of Derby in a report published this summer which found that people’s connection to nature has declined by more than 60% since 1800 – Britain ranking at the very bottom for nature connectedness in Europe.

This isn’t just sentimental. When people lose their felt connection with nature, they are less likely to act to protect it. As David Attenborough is often reported to have said, “No one will protect what they don't care about; and no one will care about what they have never experienced.”

How we reconnect: Letters to the Earth in action

At Letters to the Earth, we’ve developed practices and programmes that help people reclaim their bond with the living world. More than just going for a walk or learning about a particular species, we take people outside to build their relational attachment with the natural world - one that is deeply felt and personal, rather than intellectual or led by data. According to Miles Richardson, this is key. The types of activity he suggests are especially effective in increasing nature connectedness are those that activate the senses, engage emotions, draw our attention to beauty, and help us to explore meaning and cultivate compassion.

One foundational technique:

The Sit Spot

  • Participants choose a place in nature that is easily accessible to them - it could be on their doorstep, in their garden, a local park or another natural or wild place.
  • Over multiple visits, they sit quietly, still, with no distraction.
  • Rather than observing nature as a spectacle, they imagine entering the homes of other beings, inhabiting that space with respect and curiosity.
  • Over time, relationships form — seasonal changes, animal movements, plant life cycles become teachers.
  • This practice, when repeated, deepens sensory awareness, emotional openness, and creative insight.

Aside from the sit spot, we run Nature Think Tanks: gatherings where participants share the insights they’ve received from their time in nature, and explore implications for regenerative leadership, business models, and cultural systems. What if an organisation could be designed like a living forest — resilient, adaptive, interdependent?

Beyond the well-known mental health benefits of doing so, connecting with nature inspires something deeper: a sense of responsibility. Those who feel a genuine relationship with the natural world and feel interconnected with nature are far more motivated to protect and restore it. A 2022 systematic review ‘The Relationship Between Connectedness to Nature and Pro-Environmental Behaviors’ showed a significant positive correlation between connectedness to nature and pro-environmental behaviours.

Rethinking business and culture

If leaders, sustainability directors, educators, and policymakers began thinking like nature, what would change?

At the forthcoming Blue Earth Summit 2025 in London, we will host Nature Break events (October 1516): guided walks, writing postcards to/from Earth, and practices of reconnection woven into the conference. These are open to all — designed to seed new relational practices among individuals and organisations.

If joining in London isn’t possible, then you can sign up for a free Nature Think Tank Webinar on Tuesday 2nd December (12:30–1:30pm): tickets here.

About the author

Letters to the Earth

Letters to the Earth is an award-winning global public engagement and creative organisation, mainstreaming connection with nature for a more sustainable and regenerative world. They work with leaders, businesses, and organisations across sectors to place nature at the centre of culture and decision-making, helping to inform and guide ambitious environmental responsibility. Their outdoor immersions, letter writing workshops and storytelling campaigns inspire love and respect for the natural world in everyone and build mass engagement in environmental action. Since 2019, thousands of people around the world have been writing their Letters to or from the Earth. The letters and their messages are amplified in public artworks, media campaigns and at global climate conferences. A collection of curated letters has been published by HarperCollins UK and US in an award-winning book, Letters to the Earth, Writing to a Planet in Crisis, introduced by actor Dame Emma Thompson and illustrated by Jackie Morris. In 2020 Letters to the Earth was nominated Best Campaign by Julie’s Bicycle’s Creative Green Awards. In 2022 they won the inaugural Global Dimensions Teachers Choice Award for their 'deeply moving and motivating' educational and community resources.
