Released on March 23, 2026, the latest State of the Global Climate 2025 report from the World Meteorological Organization (WMO) delivers a stark warning: Earth’s climate system is increasingly out of balance. A rapidly growing energy imbalance where more heat is absorbed than released, is driving unprecedented warming across the atmosphere, oceans, and cryosphere, pushing the planet toward long-term and potentially irreversible changes. 

Key Highlights 

• 2015–2025 are the hottest 11 years on record globally  

• Global temperature (2025): ~1.43–1.47°C above pre-industrial levels  

• 2024 reached ~1.55°C, the hottest year recorded  

• Earth’s energy imbalance at record highs, increasing rapidly over the past two decades  

• >90% of excess heat stored in oceans, the dominant heat sink  

• Ocean warming rate has more than doubled since 2005  

• Greenhouse gas concentrations at highest levels in at least 800,000 years (CO₂, methane, nitrous oxide) 

• Carbon dioxide: 423.9 ± 0.2 ppm = 152% of pre-industrial levels. 

• Sea levels continue long-term rise, driven by thermal expansion and ice melt  

• Ocean heat content at record highs for consecutive years 

• Precipitation and water cycle extremes increased, with many regions experiencing intense rainfall, flooding and equally severe droughts as the global water cycle becomes more erratic. Only a third of rivers had normal flow; the rest were unusually dry or wet. 

• Greenland, northern Canada, western Europe, Fennoscandia, the Mediterranean, and much of Asia saw unusually high temperatures. 

Cryosphere: Key Warning Signs 

• Arctic sea ice reached record lows in 2025, with the winter maximum at ~13.8 million km² (~5–7% below the 1991–2020 average) and summer minimum ~4.6 million km² (~10–15% below average)  

• Antarctic sea ice remained well below normal throughout the year, ranking third lowest on record, with ~2.1 million km² in February (~10–15% below average) and ~17.9 million km² in September (~5–10% below average) compared to the 1991–2020 baseline  

Overall, both polar regions show persistent and significant ice loss (roughly 5–15% below long-term averages), signaling accelerating warming and a weakening of Earth’s natural cooling systems 

Why Is Earth Out of Balance? 

The growing imbalance in Earth’s energy system is directly driven by human-induced climate change. The burning of fossil fuels, deforestation, and industrial activities have sharply increased greenhouse gas concentrations, trapping heat in the atmosphere, and preventing it from escaping into space. This “heat trapping” effect intensifies warming across all Earth systems, especially oceans, which absorb most of the excess energy, creating a cascading cycle of rising temperatures, melting ice, and disrupted climate patterns. 

Global Implications  

• Intensification of extreme weather events (heatwaves, floods, storms)  

• Accelerating sea-level rise, putting countries like Bangladesh, Maldives, Vietnam, Netherlands, and small island states at highest risk  

• Ocean warming and acidification, damaging marine ecosystems and fisheries  

• Increased risks to food security, water availability, and human health  

• Long-term and potentially irreversible impacts on glaciers, ice sheets, and ocean  

Urgent Response Needed 

• Rapid reductions in greenhouse gas emissions (phasing out coal and fossil fuels) 

• Accelerated transition to renewable energy systems  

• Strengthening climate adaptation and resilience strategies  

• Expansion of early warning systems for extreme weather  

• Protection and restoration of carbon sinks (forests, wetlands, oceans)  

• Stronger global cooperation and policy action to meet climate targets
