Earth experienced its hottest year on record in 2024, crossing a critical climate threshold of 2.7°F above preindustrial levels, according to global scientists. Key findings include record ocean heat, widespread extreme weather, and atmospheric carbon dioxide hitting unprecedented levels.
The year was marked by devastating events such as U.S. flash floods, California wildfires, and severe hurricanes. Nearly 40% of the global population faced their warmest year ever, with countries like Brazil, Canada, and China setting local records. Scientists warn that without urgent action to cut greenhouse gas emissions, these trends may worsen.
Sea ice in Antarctica remained at historic lows, and experts predict rising global averages will cross permanent thresholds within a decade, risking catastrophic climate impacts. Calls for decisive climate policies are growing as the crisis intensifies.
