Melting Glaciers, Flooded Cities: The Grim Reality of 3°C Warming
12 Nov, 2025
Summary
- Global warming on track to reach 2.3-2.5°C by 2100, despite Paris Agreement
- Catastrophic impacts like sea level rise, ice sheet collapse, and extreme weather
- Urgent need for drastic action to avoid "untenable future"
As of November 12, 2025, the world is hurtling toward a catastrophic climate future. A series of reports over the past month have revealed that global warming is on track to reach 2.3-2.5°C above pre-industrial levels by the end of this century, far exceeding the 1.5°C limit set by the Paris Agreement.
This grim outlook paints a picture of a world ravaged by the impacts of climate change. Megacities are being inundated by surging seas, while mountain glaciers and ice sheets crumble into the ocean. Deadly heatwaves, wildfires, and floods have become the new normal, with the worst impacts falling on developing countries least equipped to adapt.
Experts warn that even 2-3°C of warming would be catastrophic, triggering irreversible tipping points in the climate system. Sea levels could rise by several feet, threatening the viability of coastal cities worldwide. Droughts and water shortages would become widespread, while the collapse of ecosystems like the Amazon rainforest would accelerate global warming further.
