The satellite time-lapse you see here isn't a simulation. It's a terrifying, real-world look at the 2024 Rio Grande do Sul floods, a climate catastrophe unfolding in just a few frames.
The GIF begins in early 2024, showing the city of Porto Alegre and the Guaíba Lake under normal conditions. The land is green, and the rivers are calm. But as the dates advance to late April / early May, the final frame shows a horrifying transformation. A deluge of dark, sediment-filled water explodes from the riverbanks, swallowing entire landscapes and swamping the northern parts of the metropolitan area. This is what it looks like when a region receives months' worth of rain in just a few days—an event scientists have directly linked to the intensifying power of climate change.
This disaster is not an isolated incident. It is a stark warning.
Three Decades of Broken Climate Promises
For over 30 years, the world's most vulnerable countries have been calling for climate justice at UN climate summits. Yet the Rio Grande do Sul floods reveal the catastrophic cost of delays and broken promises:
In 2009 at COP15 in Copenhagen, wealthy nations promised $100 billion annually by 2020 to help developing countries combat climate change. That goal wasn't met until 2022—and even then, at least one-third came from re-labeled existing aid budgets rather than new funding.
At COP26 in Glasgow (2021), nations committed to doubling adaptation finance by 2025 and made the first-ever explicit mention of phasing down coal. Yet the final text was weakened at the last minute, changing "phase-out" to "phasedown" of coal—a crucial difference that has allowed continued expansion of fossil fuel infrastructure.
A year later at COP27 in Sharm el-Sheikh (2022), developing countries finally won the historic establishment of a Loss and Damage Fund—after three decades of advocacy. This breakthrough came after Pakistan's devastating 2022 floods, which submerged one-third of the country and killed tens of thousands. Yet even at COP28 in Dubai (2023), initial pledges reached only $700 million—a mere 0.1% of the estimated $671 billion needed annually.
And while COP28 marked the first-ever UN agreement to "transition away from fossil fuels", the language was deliberately weakened to keep oil-producing nations on board, stopping short of the explicit "phase-out" that science demands.
COP30: Brazil's Moral Imperative
As Brazil hosts the critical COP30 climate summit in Belém in 2025, this GIF serves as powerful, non-negotiable evidence. The abstract debates over climate finance and adaptation become painfully concrete when you watch a major city disappear under water. The hundreds of thousands displaced by this flood are the human face of delayed climate action.
The flooded streets of Porto Alegre are a damning indictment: every broken promise, every watered-down commitment, every year of delay translates directly into human suffering. While developing countries struggle to secure promised adaptation funding, fossil fuel subsidies globally reached $5.9 trillion in 2020 alone—$11 million per minute.
Hosting COP30 gives Brazil both a unique platform and a moral responsibility. The world is watching, and the evidence of what's at stake—as seen in this very time-lapse—is undeniable. The discussions in Belém must move beyond promises and deliver real, immediate, and funded action to prevent more regions from suffering the same fate.
