Yet again, the world’s leaders convened, debated, produced lofty rhetoric—and left without the binding commitments, measurable targets, or decisive action that the science demands. The fact that several of the most influential leaders and governments did not attend speaks volumes. The US administration did not even bother to send delegates; however, over 100 state and local US leaders did show up. And even though China’s leadership was absent, it did send a large delegation.

Such absences are not neutral gestures; they are active signals of indifference at a moment when ecosystems are unravelling, and the window for meaningful intervention is narrowing. The persistent sabotage by powerful fossil-fuel interests, coupled with governments more preoccupied with short-term political gains than long-term planetary stability, amounts to a dereliction of responsibility so severe that future generations may struggle to comprehend our complacency.

This wilful inertia stands in stark contrast to the foundations of modern civilisation. It is science—not ideology, not wishful thinking—that has underpinned millennia of progress. Every comfort, technology, and medical safeguard we now take for granted is the result of systematic inquiry, evidence, testing, and refinement. From vaccines and antibiotics to electricity, aviation, digital communication and space exploration, science has shaped the modern world at every level, structuring our knowledge and empowering us to overcome threats that once seemed insurmountable.

To shrug off this legacy, to dismiss scientific evidence as mere opinion or “fake news”, is not only hypocritical but profoundly irresponsible. It is, frankly, stupidity on a scale that borders on self-sabotage and defies belief.

Whether out of exhaustion, tribal loyalty, cynicism or convenience, too many voters who elect such leaders appear to have ceded their responsibility to think critically—to discern credible information from manipulative noise. The rise of populism, misinformation and conspiratorial narratives has been fuelled by social media platforms designed not to inform but to inflame. Yet democratic freedoms are sustained only when citizens are informed, engaged and sceptical in the right way: sceptical of untruths, not of facts. Education, effort and intellectual curiosity are not optional extras; they are obligations. If we expect to enjoy the benefits of democracy and other hard-won freedoms, we must accept the responsibilities that accompany them.

Despite this bleak landscape, resignation is not an option. Despair, however understandable, is a luxury that the planet cannot afford. While many marine ecosystems—coral reefs, most acutely—are under escalating threat from warming seas, acidification, and compounded human pressures, there are still places where reefs thrive, demonstrating resilience when given the chance.

These pockets of hope should not lull us into complacency; rather, they should galvanise us. The truth is stark: Earth is already sliding into a new mass extinction, largely witnessed in silence. But the trajectory is not set in stone. Every degree of warming avoided, every ecosystem spared, every policy strengthened matters.

Science gives us the tools to understand what is happening and the pathways to change it. What remains is the courage—political, collective, and individual—to act. The time for equivocation has passed. The obligations of the present moment are clear, and history will judge how we respond.
