This year showed us what is possible when the world commits to action, and what happens when we hesitate.
Taken together, these stories tell us something important. The planet is under pressure, but it is not beyond hope. We have proof that global cooperation can work. We have communities adapting in real time. We have leaders, scientists, and everyday people choosing to act, even when the odds feel stacked against them.
2025 gave us a rare bit of environmental good news. The infamous hole in the ozone layer over Antarctica shrank to one of its smallest and shortest-lived sizes since 1992. Scientists aren’t calling it a full recovery just yet! Decades of work remain, but the progress is undeniable.
This milestone is a testament to what happens when the world actually works together. Decades ago, countries agreed to phase out ozone-depleting chemicals, a commitment under the Montreal Protocol. That decision, sustained over years of regulation and monitoring, is paying off in a visible, measurable way.

Climate change is not a distant threat. Across Africa, extreme weather hit hard. Floods, droughts, heat waves, and unpredictable rains disrupted livelihoods, destroyed crops, and forced families from their homes. According to the World Meteorological Organization, the continent is feeling the growing intensity of climate impacts more acutely than ever.
In Kenya, communities in the highlands of Elgeyo Marakwet were caught off guard by landslides after unusually heavy rains. Homes collapsed, and families were displaced. Local residents said they had never seen rainfall like it. These disasters are not isolated incidents but part of a pattern that is reshaping the landscape of everyday life.

Nigeria also faced catastrophic flooding, with the Mokwa region in Niger State hardest hit. Torrential rain and the failure of local water management submerged entire towns. Thousands lost their homes, and hundreds of lives were claimed.

Beyond Africa, the planet witnessed one of the most devastating ecological events of the year. In the Kerch Strait of the Black Sea, two tankers sank or ran aground, spilling heavy fuel oil into the sea. The spill killed at least 32 dolphins. Seabirds fared no better, with estimates of 15,000 to 20,000 dead or oil-covered birds. The images of wildlife struggling in the slick waters are a stark reminder that climate and environmental disasters are not only about humans but the fragile ecosystems we share.

These events show that whether it is flooding in towns, landslides in highlands, or oil-soaked seas, the impacts of extreme weather and environmental mismanagement ripple far and wide. They leave communities reeling and wildlife struggling to survive.
The natural world is sending out a warning. According to the International Union for Conservation of Nature, nearly 49,000 species worldwide are now threatened with extinction. Mammals, amphibians, corals, sharks, rays, and freshwater species are all under pressure. Each number represents a living creature struggling to survive in a world reshaped by human activity.

Bird populations are also in decline. A 2025 global assessment found that 61 per cent of assessed bird species are losing ground, driven by habitat loss, deforestation, climate change, and human expansion. These birds are more than background scenery; they are pollinators, pest controllers, and vital links in ecosystems that support food security and clean water.
Illegal trapping and trafficking of African greys has largely led to their decline.
The scale of this loss can be hard to grasp, but the consequences are tangible. Every species lost is a thread removed from the complex web of life that sustains us. The biodiversity crisis is not just about animals and plants; it is about the resilience of the planet itself, and by extension, our own survival.
In September 2025, the Second Africa Climate Summit convened in Addis Ababa. African leaders, policymakers, civil society groups, and climate practitioners came together with a clear message: Africa is ready to lead, innovate, and invest in its own climate future.
The summit emphasised Africa-led solutions, shifting the conversation from climate aid to climate investment. The focus was on long-term financing for green energy, sustainable agriculture, nature-based solutions, climate adaptation, and resilient infrastructure. This approach positions the continent not just as a recipient of support but as a hub for climate innovation, ready to attract investment and implement solutions that work for local communities.
Kenya and other African nations are increasingly showing that climate resilience can go hand in hand with economic growth. Solar projects, reforestation initiatives, and smart agriculture are just a few examples of how African countries are turning climate challenges into opportunities for leadership, job creation, and sustainable development.
The ACS2 outcome is a reminder that solutions often emerge where they are most needed. Africa is proving that with vision, coordination, and investment, the continent can be a driving force for the green transition.

In 2025, a surprising trend emerged in Kenya. A recent survey showed that public concern for climate change has dropped sharply, even as worry about deforestation remains relatively high at 43 per cent. This contrast highlights a gap between awareness and the pressing realities of climate impacts.
Those realities are hard to ignore. Analysts warn that Kenya could lose up to Sh870 billion annually due to floods, droughts, infrastructure damage, and failed harvests. These losses threaten long-term development goals and underscore that climate change is not a distant threat but a daily economic challenge.
Kenya’s situation reflects a broader dilemma: the impacts of climate change are growing faster than public perception of the threat. Bridging this gap is critical, both for fostering action at the community level and for shaping policies that protect livelihoods, infrastructure, and the environment.
A greener future is possible, but not if we ignore the problem
Across Africa, climate change is no longer just an environmental issue; it is reshaping where and how people live. A 2025 report warns that climate stress will sharply increase migration and displacement across the continent. By the end of 2024, around 185,000 people were already internally displaced, many repeatedly, by droughts, floods, and storms.
Pastoralists and rural communities bear the brunt of this upheaval. In northern Kenya, counties like Turkana and Garissa see families moving in search of water and grazing land, while riverine and flood-prone zones force other communities to flee rising waters. Each displaced family tells a story of uncertainty, loss, and the relentless pressure of changing weather patterns.
These movements are more than statistics; they reveal the human toll of climate change, showing how fragile livelihoods, food security, and community ties can be when nature’s patterns no longer follow tradition. For Africa, and for Kenya in particular, addressing climate-driven displacement is not only a humanitarian challenge but a test of resilience, adaptation, and foresight.
In November 2025, world leaders and climate practitioners gathered in Belém, Brazil, for COP30. Set against the backdrop of the Amazon rainforest, the summit was meant to move past promises and push for real action.
There were reasons for some cautious optimism. COP30 emphasised turning previous climate agreements into concrete steps, particularly on adaptation. Financing for climate resilience was boosted, and a transition framework sought to protect workers and marginalised communities as economies shift away from fossil fuels. Indigenous voices were given unprecedented representation, highlighting the importance of protecting forests and traditional land stewardship.
Yet challenges remain. A clear roadmap to phase out fossil fuels was not agreed upon, and many commitments were left voluntary or vague.
For Africa and countries like Kenya, COP30 signals both opportunity and caution. Progress on adaptation and justice-oriented climate action could benefit vulnerable regions, but without firm global mitigation, communities will continue facing mounting climate pressures. COP30 was a step forward, but the path ahead remains uncertain, and action will need to follow promises to truly make a difference.

Even in a year dominated by climate crises, there are stories of courage, ingenuity, and impact that remind us that change is possible. The Goldman Environmental Prize, often called the “Green Nobel,” recognised Semia Gharbi for her relentless fight against international waste trafficking. Her work shines a light on hidden global supply chains that dump hazardous waste in vulnerable communities, and it demonstrates how one person’s persistence can hold corporations and governments accountable.

Meanwhile, the UNEP Young Champions of the Earth program highlighted inspiring entrepreneurs under 30 who are creating innovative solutions for sustainability. Among them was Kenyan Joseph Nguthiru, whose initiatives are tackling local environmental challenges while creating economic opportunities.
These young leaders are proof that climate action isn’t just about policy and regulations, it’s also about creativity, commitment, and people turning ideas into tangible impact.

These awards remind us that progress often comes from the ground up. While global summits and regulations are crucial, it is the everyday heroes, working in communities across the world, who push the boundaries of what’s possible and inspire us all to do more.
As we move into a new year, the question is not whether climate change will shape our lives. The real question is how we respond. The choices we make, what we support, what we consume, and what we demand from leaders will determine whether next year’s story leans more toward recovery or regret.
We hope this post reminds you that climate change is not a single headline. It is a collection of choices, consequences, and moments that shape how we live now and what we pass on.
The needle can still move. But only if enough of us decide that it should. Share this to spread the message and let us know what you think!
