"Of the 34 planetary vital signs scientists track, 22 are at record levels in 2025. The year 2024 was the hottest on record, likely warmer than any period in 125,000 years, according to the report. More concerning is that warming is accelerating. Reduced aerosol emissions-typically a public health benefit-have paradoxically removed particles that were masking warming. Combined with changes in cloud behavior and declining planetary reflectivity, Earth is now absorbing more solar energy than most models predicted."
"The report, published in BioScience and backed by approximately 15,800 scientists worldwide, arrived at a pivotal moment. UN Secretary-General António Guterres said at COP30 that the world has "failed to ensure we remain below 1.5°C" and that a temporary overshoot "starting at the latest in the early 2030s-is inevitable." He called the Paris Climate Accord's 1.5°C target threshold for atmospheric warming "humanity's red line," warning that "even a temporary overshoot will have dramatic consequences.""
Global indicators show accelerating, unprecedented change: 22 of 34 planetary vital signs reached record levels in 2025 and 2024 was likely the warmest year in 125,000 years. Reduced aerosol emissions, altered cloud behavior, and declining planetary reflectivity have increased net solar absorption beyond most model projections, accelerating warming. Fire-related tree cover loss reached an all-time high, with tropical primary forest fire losses increasing 370% in one year. UN leadership states that remaining below 1.5°C has failed and a temporary overshoot in the early 2030s is inevitable, with dramatic consequences. Immediate individual and collective actions can reduce impacts on people and ecosystems.
