The longest satellite record ever assembled shows that Greenland and Antarctica have lost 11.3 trillion metric tons of ice since the 1970s, raising global sea level by more than 3 centimeters (1.2 inches)—and that most of the loss has come from glaciers flowing faster into the ocean, not from melting at the surface.

📋 Key Takeaway
The longest satellite record indicates that Greenland and Antarctica have lost 11.3 trillion metric tons of ice since the 1970s, primarily due to glaciers moving faster into the ocean. This phenomenon affects global sea levels, which is significant for countries like Iran that may face rising coastal threats. The findings highlight the urgent need for climate action globally.
🔍 Quick Context Guide
💡 Bottom Line:
The accelerating loss of polar ice is a stark reminder of the urgent need for climate action to address rising sea levels.

📰 What Happened
Recent satellite data reveals that Greenland and Antarctica have lost a significant amount of ice, primarily due to glaciers moving faster into the ocean. This loss has contributed to rising global sea levels.
- 11.3 trillion metric tons of ice lost since the 1970s.
- Global sea levels have risen by more than 3 centimeters (1.2 inches).
💡 Why It Matters
🇮🇷 For Iran: Iran, with its extensive coastline, faces potential threats from rising sea levels, impacting its coastal cities and infrastructure.
🌍 Regional: Other regional countries with coastlines may also face similar threats, influencing regional stability and migration patterns.
🌐 International: The findings underscore the urgency for global climate action and cooperation to mitigate climate change effects.
📚 Background
