Global temperatures are expected to remain alarmingly high, surpassing the critical threshold of 1.5°C above pre-industrial levels for a significant number of years ahead, an analysis by the World Meteorological Organisation (WMO) and the UK’s Met Office has revealed. After the record temperatures of 2024, which marked the first time global averages exceeded this threshold, the new predictions suggest an 86% probability that another year within the next five could also breach it.

This sobering assessment highlights that, on average, global temperatures could range from 1.1°C to 1.9°C above the baseline of 1850-1900 during the years from 2024 to 2028. The analysis posits a 70% chance that the average temperature over this timeframe will exceed 1.5°C. Furthermore, there exists an 80% likelihood that at least one year between 2025 and 2029 could establish a new record for global temperatures, potentially surpassing the warmest year of 2023.

The first occurrence of annual temperatures exceeding 1.5°C has prompted intensified scrutiny of climate patterns and policies. Influential climate events such as El Niño, which has significantly contributed to the recent spikes in temperature, are seamless with these projections. Additionally, environmental changes are poised to exacerbate weather extremes. Forecasts indicate wet winters for northern Europe, raising severe flooding risks, particularly for regions that are susceptible to such climate hazards.

Professor Adam Scaife from the Met Office addressed these unfolding scenarios, noting that the occurrence of 1.5°C years is becoming increasingly commonplace. He remarked, “These are shocking statistics… we are going to see more of these.” While the prospect of a year exceeding 2°C of warming remains extremely unlikely—at only a 1% chance—the very fact that it is now conceivable speaks volumes about the increasingly precarious state of the global climate.

The recent surge in temperatures aligns closely with international climate commitments under the Paris Agreement, which aims to limit global warming to well below 2°C while pursuing efforts to curb it to 1.5°C. The latest data from the Copernicus Climate Change Service corroborates findings that the last year was the warmest ever recorded, exceeding 1.6°C above pre-industrial averages. As stated by UN Secretary-General António Guterres, the intensifying climate phenomena call for urgent measures to curtail carbon emissions, with aspirations for a 30% reduction in fossil fuel output and usage by 2030.

Despite these urgent calls, political momentum around climate action appears to be waning in various regions, complicating efforts to navigate the escalating crisis. The interconnection between environmental degradation—evidenced by rising wildfires, aqueous extreme weather, and drought conditions in critical areas like the Amazon—emphasises that immediate and comprehensive action is essential to mitigate further temperature rises.

Ko Barrett, WMO’s deputy secretary-general, highlighted the distressing trend, stating, “We have just experienced the 10 warmest years on record.” This observation intimates not only a future marked by further climatic instability but also that the repercussions will increasingly challenge economies, everyday life, and ecosystems worldwide. With scientific research suggesting a rapid acceleration of climate change, the evidence points towards an urgent mandate for policymakers to elevate their commitment to environmental sustainability.

The climate crisis is rapidly intertwining with the fabric of the global landscape, necessitating a collective shift towards more substantial action to avert catastrophic consequences and secure a sustainable future.
