**Summary:**

1. **Urgent Warning**  
Scientists from **15 countries** have issued an open letter highlighting that the potential collapse of the **Atlantic Ocean’s main circulation system (AMOC)** has been severely underestimated, posing a significant risk to global climate stability.

2. **Signs of Weakening**  
Oceanographer **Stefan Rahmstorf** notes that the AMOC has shown signs of weakening over the past **60 to 70 years** , including a persistent **cold spot** in the northern Atlantic and **record-low salt levels** in seawater.

3. **Tipping Point Estimates**  
Rahmstorf estimates there is a **50% chance** the AMOC could reach a critical tipping point this century, leading to drastic climate changes.

4. **Potential Consequences**  
The collapse could result in severe outcomes such as regional cooling in **northwestern Europe** , altered rainfall patterns, and increased **sea levels** , affecting millions.

5. **Global Impact**  
The warning emphasizes the interconnectedness of climate systems and the urgent need for action to mitigate potential impacts on global weather and ecosystems.
