Ten years ago, the world stood at a crossroads, and the Paris climate treaty emerged as a beacon of hope. But here’s the shocking truth: despite its promise, the journey since has been fraught with challenges, controversies, and unexpected victories. Today, as we reflect on this pivotal moment, it’s clear that the treaty didn’t just change the world—it sparked a revolution in how we think about our planet’s future. And this is the part most people miss: the story of the Paris treaty is not just about agreements on paper; it’s about the relentless fight for survival, the power of the underdog, and the unexpected twists that have brought us to where we are today.
As a journalist covering the 2015 conference, I remember the skepticism in the air. Could 194 nations truly unite on something as complex as climate action? The night before the agreement, even the most seasoned observers doubted it. Yet, against all odds, they did. But let’s be honest: the Paris treaty wasn’t a magic bullet. It was a starting point, a fragile promise in a world teetering on the edge of climate catastrophe. Fast forward to today, and the narrative is far from simple. We’ve made progress, but we’ve also stumbled. The question remains: is it enough?
And this is where it gets controversial: In July 2024, the International Court of Justice (ICJ) delivered a ruling that could reshape the treaty’s legacy. For the first time, nations were legally obligated to act on climate change, with enforceable consequences for inaction. Greenpeace International hailed it as a game-changer, emphasizing that states must regulate businesses to prevent harm from emissions, regardless of where that harm occurs. But here’s the kicker: the ICJ also declared that the right to a clean, healthy, and sustainable environment is fundamental to all human rights. Bold? Absolutely. Achievable? That’s where opinions diverge. Critics argue that enforcement will be nearly impossible, while optimists see it as a turning point. What do you think? Is this ruling a breakthrough, or just another idealistic promise?
The journey to this ruling began with 27 law students from the University of the South Pacific in 2019. Facing the daunting question of what they could do about climate change, they didn’t let their status as students or their origins in small island nations hold them back. Instead, they embarked on a mission to take their case to the ICJ in The Hague. Partnering with Blue Ocean Law, an indigenous-led firm, and backed by Vanuatu as the plaintiff, they challenged the world’s most powerful nations. Their unanimous victory wasn’t just a legal win; it was a testament to the power of grassroots action. But the real test lies in implementation. Will nations act before they’re dragged to court, or will it take legal battles to force change?
One of the most overlooked aspects of the Paris treaty is the fight over the 1.5-degree target. Initially, global powers pushed for a ‘reasonable’ 2-degree threshold, a number that would have been catastrophic for many vulnerable nations. It was the Climate Vulnerable Forum, representing mostly Global South countries, that fought tirelessly to lower the target. Their chant, ‘1.5 to stay alive,’ became a rallying cry. Against all odds, they succeeded, and 1.5 degrees became the benchmark. Even though we’ve already breached this limit, imagine where we’d be if the target had been set at 2 degrees. Would we have grown complacent in the face of even greater devastation?
The ripple effects of this advocacy are profound. When small island nations demanded the 1.5-degree target, they also pushed for a special IPCC report on the policies needed to achieve it. Released in 2018, the report sent shockwaves around the world with its ‘12 years to act’ warning. It reshaped the global policy conversation, leading to ambitious goals like halving pollution by 2030. In the U.S., this momentum culminated in the Inflation Reduction Act, the most significant climate legislation in American history. Yet, the Act’s impact has been uneven, with parts of its funding and implementation still in limbo. Globally, progress remains patchy. Deforestation continues, fossil fuel subsidies persist, and our lifestyles remain largely unsustainable.
But here’s a glimmer of hope: the renewables revolution. A decade ago, renewables were more expensive and less accessible than fossil fuels. Today, solar power has outpaced nearly all predictions. In 2025, wind and solar surpassed coal as the world’s primary energy source. Countries like Denmark now get 90% of their electricity from clean sources, while in Pakistan, small-scale solar panels from China have sparked an energy revolution. Even in Australia, solar power is so abundant that electricity is free for three hours daily. Innovations in battery storage have addressed intermittency issues, with California now producing over 100% of its daytime electricity needs from renewables, storing the excess for nighttime use. China, too, has made strides, with its CO2 emissions stabilizing or declining over the past 18 months.
Is this progress enough? Not by a long shot. We’re still on track for 2.5 degrees of warming, a far cry from the 1.5-degree target. But we’ve ‘bent the curve’—before Paris, we were headed for 4 degrees. The question now is: can we bend it further, and faster? In an ideal world, global leaders would have heeded early warnings, and we’d be well into a sustainable energy transition. But thanks to the relentless efforts of activists, leaders, and nations, we’re not in the worst-case scenario either. Landmarks like the Paris treaty, the Vanuatu victory, and the renewables revolution matter. They show what’s possible when we fight for our future.
Here’s the provocative question to leave you with: As we celebrate these victories, are we doing enough to hold the powerful accountable? Or are we settling for incremental change when radical transformation is what’s needed? Share your thoughts in the comments—let’s keep this conversation alive. Because while it may have been too late to save everything for decades, it’s never too late to save what we can.
