🗞️ Driving the news: A new study warns that even temporarily surpassing the 1.5°C global warming threshold could cause irreversible climate impacts, such as long-term sea level rises and the thawing of carbon-rich permafrost
The study stresses that overshooting this limit would not deliver the same outcomes as preventing it altogether

🔭 The context: The 1.5°C target, established by the Paris Agreement, is slipping out of reach as global emissions continue to rise
Existing climate pledges point to nearly 3°C of warming by 2100, far beyond what is considered safe for the planet

🌍 Why it matters for the planet: Exceeding 1.5°C could trigger tipping points with lasting impacts for centuries, including devastating consequences for low-lying island nations and global ecosystems

⏭️ What's next: To avoid these irreversible changes, emissions must be cut drastically by 2030, and net zero must be achieved by 2050
Massive scaling of carbon removal technologies will also be needed if overshoot occurs

💬 One quote: “Even if you brought temperatures back down again, the world... is not the same as if you didn't overshoot" - Carl-Friedrich Schleussner, the study's lead author

📈 One stat: Existing climate pledges would result in nearly 3°C of warming by 2100, according to the UN
