This report compiles the most significant extreme weather events that occurred during 2025 and analyses their possible relationship with climate change. This analysis enables what is known as climate attribution to be carried out, which, on the one hand, can indicate a higher probability of events such as heat waves, fires, droughts, as well as heavy rains, floods or hurricanes, as a consequence of climate change; and, on the other hand, can point to possible changes in the intensity or extent of these events.

Over the last ten years, the global average temperature has risen by 0.3°C. Although this increase may seem small, it translates into an average of 11 additional days of extreme heat per year. In addition, heatwaves have become ten times more likely, underscoring that every tenth of a degree we manage to avoid is, in itself, a significant achievement.

The impacts of the extreme events of 2025 highlight the vulnerability of certain regions of the Global South, with the disproportionate risk faced by women in places such as South Sudan being particularly notable, where their lower job qualifications force them into more exposed jobs, such as agriculture or street vending.

Another injustice of the climate crisis highlighted in the report concerns the scientific studies themselves, as climate models are better calibrated for the northern hemisphere. This, together with the lack of observational data in the southern hemisphere, hinders the accuracy of analyses and the quality of predictions for countries in the Global South.

The report urges improved adaptation measures in response to the climate emergency, but also warns that in some cases, as happened during Hurricane Melissa, these measures may prove insufficient. This highlights the need to drastically reduce emissions in order to curb the escalating impacts.
