🗞️ Driving the news: A newly identified tipping point for ice sheet loss could lead to higher-than-expected sea level rise
• Warming seawater intruding beneath ice sheets creates cavities, leading to increased melting and ice collapse

🔭 The context: This feedback loop can be triggered by minor temperature increases, which could occur within the next few decades
• According to the scientists, current models may underestimate sea level rise because they don't fully account for seawater intrusion

🌍 Why it matters for the planet: Sea level rise threatens to submerge major cities and affect billions of people
• This highlights the urgent need for dramatic climate action to limit global warming

⏭️ What's next: Scientists plan to incorporate seawater intrusion into ice sheet models to better predict future sea level rise
• Monitoring and realistic modeling of these processes are essential for accurate predictions

💬 One quote: “With every tenth of a degree of ocean warming, we get closer and closer to passing this tipping point,” said Dr. Alexander Bradley of the British Antarctic Survey

📈 One stat: Seawater intrusion could double the rate of ice loss from some Antarctic ice shelves
