🗞️ Driving the news: A 2021 study in Nature Geoscience reveals the Atlantic Gulf Stream is at its weakest in over 1,600 years due to rising global temperatures from human-induced climate change. This slowdown threatens to exacerbate climate change impacts globally

🔭 The context: The Gulf Stream, part of the Atlantic Meridional Overturning Circulation (AMOC), plays a vital role in regulating Earth's climate by redistributing heat
Its weakening is attributed to climate change, impacting weather patterns and sea levels.

🌍 Why it matters for the planet: The AMOC's slowdown could lead to more extreme weather, higher sea levels, and reduced habitability of land
It decreases the ocean's ability to absorb atmospheric CO2, increasing greenhouse gas levels.

⏭️ What's next: While a complete halt of the AMOC is unlikely, its continued weakening is expected. Monitoring and research into ocean circulation and potential weather impacts are crucial for climate action.

💬 One quote: "Scientists warn that should increasing temperatures persist, the AMOC could reduce by at least 34% to 45% and reach a critical 'breaking point' by 2100," highlighting the urgency of addressing climate change.

📈 One stat: The AMOC could weaken by 34% to 45% by 2100 if current temperature trends continue.
