Global Temperatures Poised to Exceed Key Thresholds in Coming Years
World Meteorological Organization forecasts significant likelihood of record-breaking heat within the next five years.
The World Meteorological Organization (WMO) has issued a report revealing that there is an 80% chance that global temperatures will break at least one annual heat record between 2025 and 2029. This projection raises concerns about the increased risk of extreme weather events, including droughts, floods, and forest fires.
The report also indicates a small possibility that a year could occur before 2030 with global average temperatures at least 2°C above preindustrial levels, an outcome scientists have termed 'shocking.'
This report follows the trend of the previous decade, which included the hottest ten years ever recorded.
The analysis synthesizes short-term weather observations and long-term climate projections, suggesting a 70% chance that the average temperature for 2025-2029 will exceed 1.5°C above preindustrial levels, bringing the world closer to breaching the primary target set by the Paris Agreement—a treaty aimed at limiting global warming.
Moreover, there is an 86% likelihood that the 1.5°C threshold will be exceeded in at least one year within the next five years, a significant increase from 40% reported in 2020.
The year 2024 marked a critical point when the global temperature exceeded the 1.5°C threshold on an annual basis for the first time.
This measure was deemed implausible in earlier predictions.
As of now, scientists estimate that warming has reached approximately 1.4°C above preindustrial levels, based on a baseline from 1850-1900.
The report provides a comprehensive overview based on contributions from 220 models across 15 different institutions, including the UK’s Met Office and the Barcelona Supercomputing Centre, highlighting how Arctic regions are predicted to warm at a pace 3.5 times faster than the global average.
This rapid warming is attributed to feedback mechanisms such as melting sea ice, which diminishes the Earth's capacity to reflect sunlight.
Regions such as the Amazon rainforest are expected to encounter more frequent droughts, while other areas, including northern Europe and South Asia, anticipate increased rainfall.
Experts indicate that the next few years are likely to experience extreme climatic conditions, with predictions suggesting that 2025 may emerge as one of the warmest years on record.
The WMO’s climate services director described the outlook as 'worrying' for both heatwaves and public health, calling for urgent climate action to mitigate these risks.
The report asserts that while the likelihood of temperatures exceeding 2°C is presently low—approximately 1%—the statistical significance of this possibility has grown, highlighting a concerning shift in climate trends.
The combination of factors contributing to this increase includes phenomena such as El Niño, which influences global temperature fluctuations.
The findings of this report underscore the pressing challenge faced by global leaders in their efforts to curb climate change, with extreme weather events expected to increasingly affect economies, natural ecosystems, and community well-being around the world.
