2024 Confirmed as Earth's Hottest Year, Breaching Key Climate Threshold
Global temperatures in 2024 temporarily exceeded the critical 1.5°C warming limit, underscoring the escalating impacts of climate change.
- NASA and other global agencies confirmed 2024 as the hottest year on record, with average temperatures 1.47°C above pre-industrial levels.
- For over half of 2024, temperatures exceeded the critical 1.5°C threshold outlined in international climate agreements, though this breach is not yet sustained over decades.
- The warming trend has been driven by greenhouse gas emissions, with carbon dioxide levels now at approximately 420 parts per million, a significant rise from pre-industrial levels.
- Extreme weather events intensified in 2024, including 27 billion-dollar disasters in the U.S., with Hurricane Helene causing $79 billion in damages and claiming 219 lives.
- Scientists warn that rapid emission reductions are essential to avoid long-term breaches of the 1.5°C limit, as the planet continues to experience worsening wildfires, rising sea levels, and intensified heat waves.
