- The world is set to overshoot the 1.5°C global warming limit, with the 2023-2025 period breaching this threshold.
- Climate scientists warn of devastating consequences, including severe weather, ecosystem collapse, and irreversible tipping points.
- The Paris Agreement's 1.5°C target is considered failed due to a decade of weak action on emissions.
- Natural carbon sinks (forests, oceans) are weakening, accelerating CO2 buildup in the atmosphere.
- Tipping points, such as Amazon rainforest dieback and Arctic permafrost melt, could trigger cascading climate disasters.
- Ocean warming and marine heatwaves threaten coral reefs, which may die off by mid-century.
- Greenland and Antarctic ice sheets are melting rapidly, risking unstoppable sea-level rise.
- The Atlantic Meridional Overturning Circulation (AMOC) could collapse, disrupting global weather patterns.
- Geoengineering proposals, like solar radiation modification, are controversial and risky.
- Negative emissions (e.g., reforestation, carbon capture) are needed but remain politically and technologically unfeasible at scale.
