🌍Scientists Uncover Secret Heat Source Beneath East Antarctica

🌍 East Antarctica Warming Faster Than Expected: Hidden Climate Driver Discovered

📌 Introduction

For decades, scientists believed East Antarctica’s icy interior was stable. But a 30-year climate study has revealed a hidden atmospheric mechanism rapidly warming the region — which holds most of the world’s glacial ice.

🔍 The Discovery

Researchers from Nagoya University analyzed temperature data from 1993 to 2022 at remote weather stations — Dome Fuji, Relay, and Mizuho. They found that East Antarctica’s interior is warming at 0.45–0.72°C per decade, outpacing the global average.

🌊 The Hidden Climate Driver

The warming is driven by warm air transported from the Southern Indian Ocean. Shifts in ocean temperatures are altering atmospheric circulation, funneling heat deep into Antarctica — a process not captured by current climate models.

❄ Why It Matters

East Antarctica contains 70% of Earth’s freshwaterice loss could accelerate, contributing significantly to global sea level rise. This challenges long-held assumptions about Antarctic stability.

📊 Key Facts from the Study

• Duration: 30 years (1993–2022)
• Stations Used: Dome Fuji, Relay, Mizuho
• Warming Rate: 0.45–0.72°C per decade
• Cause: Warm air inflow from Southern Indian Ocean
• Risk: Faster ice melt, underestimated sea level rise

🌐 Global Implications

This discovery is a wake-up call for climate scientists and policymakers. If hidden climate drivers like this remain unaccounted for, future projections of ice loss and sea level rise could be dangerously low.

📝 Conclusion

Antarctica’s icy heart is not immune to climate change. This hidden heat source could reshape our understanding of polar stability — and intensify the urgency for global climate action.
