🌍 1.5°C Isn’t Enough—New Study Warns Ice Sheets Need 1°C to Survive

The Paris Agreement’s 1.5°C goal may not be enough to prevent catastrophic ice loss, says a new study in Communications Earth & Environment. Researchers from Durham University warn that even at 1.5°C, Greenland & Antarctica could melt enough to cause meters of sea-level rise, displacing millions.

🔬 Key Findings:

• Ice sheets are losing 370 billion metric tons/year at just 1.2°C warming (IPCC).

• 1.5°C could trigger unstoppable ice loss, flooding coastal cities.

• A safer target? 1°C or lower—but CO₂ levels are already 424 ppm (vs. 350 ppm in the 1990s).

⚠️ Why It Matters:

• 230 million people live within 1 meter of sea level.

• Once ice melts, recovery could take millennia—even if temps drop.

• "Every fraction of a degree matters," says lead author Prof. Chris Stokes.

🌊 The Urgency:
Policymakers must act now to avoid irreversible damage. The time to #SaveOurIce is running out.
