Opinion | Navigating a warming world
Summary
The planet is experiencing rapid warming with 2024 marking the hottest year on record at 1.55 degrees Celsius above pre-industrial levels. This decade is witnessing temperature thresholds previously thought distant, posing urgent climate risks including potential irreversible impacts due to climate overshoot.
Key Points
- Global temperature is rising rapidly, with 2024 being the hottest year on record at 1.55 degrees Celsius above pre-industrial levels.
- The 1.5 degrees Celsius warming threshold, once seen as a distant goal for 2100, is now being surpassed within this decade, increasing climate risks.
- Overshoot of temperature limits may cause irreversible environmental impacts and amplify risks through cascading hazards and teleconnections.
- Urgent action is needed to reduce emissions, enhance renewable energy, protect natural carbon sinks, and improve climate risk governance to manage overshoot and its consequences.
