Record-Breaking Heat: A Call to Action in the Face of Climate Change
The planet has witnessed unprecedented temperature levels, with global averages exceeding preindustrial levels by 1.75ºC for 18 out of the last 19 months. This alarming trend underscores the urgency with which we must address climate change, especially given that 2024 has been recorded as the hottest year in history, marking the first time we surpassed the critical 15-degree Celsius threshold.
January 2025 brought shocking statistics as well, becoming the warmest January since global records began. The global average temperature reached 13.29ºC, which is a staggering 0.79ºC higher than the average from 1991-2020. These figures are not mere data points; they reveal the reality of our changing climate. Across Europe, even in the midst of winter, average temperatures soared to 18ºC, 2.5ºC above normal, according to the Copernicus Climate Change Service. This anomaly includes regions stretching from southern Europe to close to the Arctic, indicating that the impacts of climate change are widespread.
This alarming data indicates a sustained period where the global average temperature has exceeded the 1.5ºC threshold—an established safety limit set by scientists and enshrined in the Paris Agreement for 2100. It is essential to comprehend that we are not just experiencing isolated heat waves; we are witnessing a systematic, long-term trend that threatens the very fabric of our environment.
In January 2025, despite the development of the La Niña phenomenon—which usually cools global temperatures temporarily—we saw continued record-breaking warmth. This contradicts expectations and highlights the compounded effects of climate change that cannot be ignored. As Samantha Burgess, Climate Manager at the European Centre for Medium-Range Weather Forecasts, pointed out, the persistence of these extraordinary temperatures serves as a stark reminder of the challenges ahead.
The warming of ocean waters is another critical aspect of this climate crisis. In January 2025, excluding polar regions, ocean temperatures reached 20.78ºC, only 0.19ºC shy of the highest recorded level for that month in 2024. This heating of ocean waters poses significant risks to marine ecosystems and the livelihoods that depend on them.
As January came to a close, February brought startling temperatures in the North Pole, where readings reached around 0ºC—just above the melting point of sea ice. This is particularly concerning as it jeopardizes the thickening and expansion of the Arctic ice cap during this time of year. Furthermore, it is noteworthy that January recorded one of the lowest extents of Arctic sea ice, being 6% below average and nearly tied with January 2018.
These developments signify a climate emergency that could have dire consequences. The evidence could not be clearer: our planet is warming at an alarming rate, and the time for action is now. As we face an existential challenge, it is paramount for individuals, governments, and organizations to come together to create and implement effective solutions to combat climate change. The stakes have never been higher, and inaction could lead to catastrophic outcomes for future generations.
