The World Meteorological Organization (WMO) Report 2025 has delivered a powerful warning about the state of our planet. According to the latest data, global temperatures are rising faster than ever, extreme weather events are becoming more frequent, and urgent action is needed to avoid long-term damage. From melting glaciers to deadly heatwaves, the report highlights the growing impact of climate change on ecosystems, economies, and everyday lives. This year’s findings serve as a crucial reminder that the time to act is now—before these warnings become irreversible realities.
Introduction
The climate crisis is no longer a distant threat—it’s here, and it’s getting worse. The WMO Report 2025, officially the “WMO Global Annual to Decadal Climate Update (2025-2029)” released by the World Meteorological Organization on May 28, 2025, delivers a sobering look at our planet’s climate trajectory. This global climate report provides critical climate change data, highlighting rising global temperatures, extreme weather trends, and the urgent need for action. As we face a climate emergency 2025, this report serves as both a warning and a call to action for governments, businesses, and individuals.

Key Findings of the WMO Report 2025
The WMO environmental report offers a detailed forecast for 2025-2029, based on data from 101 countries and various scientific organizations. Here are the most significant WMO climate findings:
- Temperature Projections: The report predicts that global mean near-surface temperatures for each year between 2025 and 2029 will be between 1.2°C and 1.9°C higher than the 1850-1900 pre-industrial average. This global warming update 2025 suggests we’re on track for some of the hottest years in history. There’s an 80% chance that at least one year in this period will surpass 2024, currently the hottest year on record 2025, with a global mean temperature of 1.55 ± 0.13°C above pre-industrial levels.
The 1.5°C Threshold, a critical limit set by the Paris Agreement, with a 70% chance that the five-year average for 2025-2029 will also surpass this mark. - Regional Climate Variations: The report highlights significant regional differences. The Arctic is warming faster than the global average, amplifying risks like permafrost thaw and sea ice loss. Precipitation patterns are also shifting, with big regional variations that could lead to droughts in some areas and floods in others. These findings align with the UN climate report 2025, emphasizing the need for region-specific adaptation strategies.
- Irreversible Impacts: Some climate changes are now locked in for centuries. Sea-level rise 2025 has accelerated, doubling from 2.1 mm/year (1993-2002) to 4.7 mm/year (2015-2024). Ocean warming, with oceans absorbing 90% of excess heat, has reached record levels, fueling stronger storms and causing coral bleaching. Glacier mass loss from 2021-2024 was the most severe in three years, particularly in regions like Norway, Sweden, Svalbard, and the tropical Andes.
| Climate Indicator | Key Data (2024-2025) | Impact |
|---|---|---|
| Global Temperature | 2024: 1.55 ± 0.13°C above 1850-1900; 2025-2029: 1.2°C-1.9°C | Record-breaking heatwaves, increased extreme weather |
| Sea-Level Rise | 4.7 mm/year (2015-2024), doubled from 2.1 mm/year (1993-2002) | Threatens coastal communities, ecosystems |
| Ocean Heat Content | Record highs for 8 consecutive years | Stronger storms, coral bleaching, ecosystem disruption |
| Glacier Mass Loss | Most severe 3-year loss (2021-2024) | Reduced water availability, rising sea levels |
| Greenhouse Gas Levels | Record highs in 2023 (CO2, methane, nitrous oxide) | Accelerates warming, long-term climate impacts |

The Human and Environmental Toll
The WMO global climate indicators reveal a crisis that’s already reshaping lives. Extreme weather trends 2025, including record-breaking heatwaves, droughts, and floods, displaced 36 million people in 2024—the highest in 16 years. In China, 15 million were displaced after a Sichuan earthquake, while hurricanes in the US and floods in Brazil and Africa affected millions more. These weather extremes 2025 are not just natural disasters; they’re climate-driven events that undermine resilience and create new risks for vulnerable populations.
- Sea-Level Rise: The accelerated rise threatens coastal cities and small island nations, with economic and ecological consequences.
- Ocean Warming: Record ocean heat content in 2024 fueled stronger storms and disrupted marine ecosystems, impacting fisheries and coastal livelihoods.
- Food and Water Security: Droughts and shifting precipitation patterns are increasing food insecurity, with at least eight countries reporting a million more people facing acute food insecurity in 2024 compared to 2023.
These impacts highlight the human cost of the climate crisis 2025, making it clear that inaction is not an option.

Comparing IPCC vs WMO Report
While the WMO Report 2025 focuses on short-term climate projections (2025-2029), the IPCC reports provide longer-term assessments, often looking decades ahead. The WMO’s annual updates, like this one, offer timely data on immediate trends, complementing the IPCC’s broader scenarios. Both emphasize the 1.5°C threshold, but the WMO’s focus on near-term risks underscores the immediate need for action, while the IPCC provides a framework for long-term mitigation and adaptation strategies.
A Glimmer of Hope: Renewable Energy
Despite the dire warnings, the WMO Report 2025 offers hope through the rapid growth of renewable energy. In 2023, renewable capacity additions surged by nearly 50% compared to 2022, reaching 510 gigawatts. This growth, driven by solar, wind, and hydropower, is a critical step toward decarbonization. However, the report stresses that greenhouse gas levels 2025 remain at record highs, with CO2, methane, and nitrous oxide continuing to rise.
To limit warming to 1.5°C, global emissions must peak before 2025 and be reduced by 43% by 2030. Methane emissions, a potent greenhouse gas, need to be cut by about a third. These targets are ambitious but achievable with global cooperation and investment in sustainable technologies.

The Path Forward: Urgent Climate Action
The WMO Report 2025 is a call to action, emphasizing the need for immediate and deep emissions reductions. Here’s what needs to happen:
- Policy Leadership: Governments must strengthen Nationally Determined Contributions (NDCs) under the Paris Agreement and secure ambitious financing at COP29 to turn plans into action.
- Business Innovation: Companies should invest in renewable energy, energy efficiency, and sustainable practices to reduce their carbon footprint.
- Community Resilience: Early warning systems and climate services, as highlighted in the report, can protect communities from extreme weather events, but they require global investment.
- Individual Action: From reducing energy use to advocating for change, individuals can contribute to a more sustainable future.
The report also underscores the importance of global cooperation. The climate crisis knows no borders, and initiatives like the UN climate report 2025 and international summits are critical for coordinating efforts.
Engaging with the Climate Crisis
The climate crisis can feel overwhelming, but it’s also an opportunity to unite as a global community. Stay informed through reports like the WMO Report 2025, support sustainable initiatives, and advocate for policies that prioritize the planet. Together, we can turn the tide against the climate emergency 2025 and create a sustainable future for all.
Conclusion
The WMO Report 2025 is a stark reminder that the climate crisis is escalating, with rising global temperatures, sea-level rise, and extreme weather events reshaping our world. Yet, it also offers hope through the growth of renewable energy and the potential for collective action. By understanding these findings and acting decisively, we can mitigate the worst impacts and build a more resilient future. The time to act is now—every degree, every action, and every voice matters.
FAQs
