WMO: Global Temperature Could Temporarily Exceed 1.5°C Limit Within Five Years

The World Meteorological Organisation (WMO) has recently released a report indicating a significant risk of the annual average global temperature momentarily surpassing 1.5°C above pre-industrial levels within the next five years. This increase signals a concerning approach towards the upper limit of global warming targets established by the Paris Agreement, emphasizing the urgency for enhanced climate action.

According to the WMO's findings, there is an 80% chance that we will witness a temporary leap beyond the 1.5°C threshold at some point between 2024 and 2028. This projection is not a prediction of long-term climate trends, which the Paris Agreement aims to mitigate, but rather a short-term fluctuation that underscores the immediate impacts of global warming.

The report forecasts that the global mean near-surface temperature for each year from 2024 to 2028 will be between 1.1°C and 1.9°C above the baseline period of 1850-1900. There is an 86% probability that this period will witness the hottest year on record, surpassing the temperatures of 2023. Furthermore, the likelihood of the average temperature for the five-year span from 2024 to 2028 exceeding 1.5°C above pre-industrial levels is now at 47%, a noticeable increase from the 32% probability for the 2023-2027 period reported last year.

Implications for Global Climate Goals

This alarming update comes as the United Nations Secretary-General António Guterres delivered a significant speech advocating for more ambitious climate measures. His address was strategically timed ahead of the G-7 summit, set to take place in Italy from June 13 to 15, underscoring the critical need for global leaders to commit to more rigorous efforts in combating climate change.

The WMO's report serves as a crucial reminder of the pressing challenge that climate change poses to the global community. It calls for immediate and decisive action to curtail greenhouse gas emissions and halt the temperature rise, to align with the long-term goals of the Paris Agreement. As the world edges closer to the 1.5°C mark, the need for concerted international collaboration and innovative solutions has never been more apparent.

The findings underscore the urgency of adopting sustainable practices and policies that can effectively reduce the impacts of climate change. As global temperatures continue to trend upwards, the window for achieving the targets set out in the Paris Agreement narrows, making the forthcoming G-7 summit a pivotal moment for climate diplomacy.
