WMO Climate Outlook 2025-2029 delivers a crucial forecast, indicating that global temperatures will remain at or near record highs over the next five years. This continued warming is set to intensify climate risks, affecting societies, economies, and sustainable development worldwide.
Understanding the WMO Climate Forecast for 2025-2029
According to the report, the annually averaged global mean near-surface temperature for each year between 2025 and 2029 is predicted to rise between 1.2°C and 1.9°C above the average levels recorded from 1850 to 1900. This substantial increase highlights a concerning trend: our planet is heating at an unprecedented rate.
Moreover, the forecast gives an 80% chance that at least one year between 2025 and 2029 will surpass the warmest year on record, currently set by 2024. Even more striking, there is an 86% chance that at least one year during this period will exceed the critical 1.5°C warming threshold above pre-industrial levels.
WMO Climate Outlook: Why These Predictions Matter
The predicted rise in global temperatures is more than just a number. There is a 70% chance that the average warming over the five years from 2025 to 2029 will surpass 1.5°C. This probability has risen sharply from previous years, reflecting accelerating climate change:
- 47% chance in last year’s 2024-2028 report
- 32% chance in the 2023 2023-2027 report
Every additional fraction of a degree in warming increases the severity of climate impacts. These include:
- More frequent and intense heatwaves
- Severe rainfall and flooding events
- Prolonged droughts affecting agriculture and water supply
- Accelerated melting of ice sheets, glaciers, and sea ice
- Rising ocean temperatures and sea levels
Such changes pose serious threats to global ecosystems and human well-being.
Implications for Societies and Economies
The WMO climate outlook emphasizes that the rising temperatures will significantly challenge sustainable development goals worldwide. Communities will face greater risks from natural disasters, threatening food security, health, infrastructure, and economies.
Governments, businesses, and individuals must prepare and adapt to these intensifying impacts. Investing in climate resilience, reducing greenhouse gas emissions, and accelerating clean energy transitions are more urgent than ever.
Final Thoughts
WMO Climate Outlook 2025-2029: Staying Ahead with WMO’s Climate Update
The WMO Global Annual to Decadal Climate Update 2025-2029 provides an essential guide for policymakers, researchers, and the public. It highlights the urgent need for decisive climate action to mitigate risks and safeguard our future.
By understanding these forecasts and their implications, we can better prepare for a changing world — ensuring resilience and sustainability for generations to come.
