Global temperatures remained near-record highs in April, according to the European Union’s climate monitor, the Copernicus Climate Change Service (C3S). This persistence in high temperatures, despite the expectation that they would cool down following the fading of El Niño conditions in 2023, has raised concerns among climate scientists. Johan Rockstrom, director of the Potsdam Institute for Climate Impact Research, expressed serious worry over this trend, stating that the world seems to be stuck in an accelerated step-change in warming. In April, global temperatures were the second-highest on record since 1940, drawing on extensive data from satellites, ships, aircraft, and weather stations. Almost all of the last 22 months have seen temperature increases surpassing 1.5 degrees Celsius above pre-industrial levels. This threshold is significant as it marks the limit set by the Paris Agreement to avoid catastrophic environmental changes. The study conducted by C3S indicates that the current global temperature stands at 1.39 degrees Celsius above pre-industrial levels. Based on the warming trend observed over the last three decades, the service projects that the 1.5-degree mark could be breached by mid-2029, or even sooner. Samantha Burgess, a climate scientist at the European Center for Medium-Range Weather Forecasts, which oversees C3S, echoed these projections, emphasizing the necessity to focus on minimizing further warming even after the 1.5-degree threshold is crossed. Julien Cattiaux, a climate scientist at the French National Center for Scientific Research (CNRS), noted the alarming pace at which temperature increases are occurring. However, he stressed the importance of continued action despite the daunting statistics. The rapid rise in temperatures has been primarily attributed to the burning of fossil fuels, which has long been identified as the primary driver of global warming. While the role of fossil fuels is well-established, scientists are still investigating other potential contributors to this persistent warming, including changes in global cloud patterns, airborne pollution, and the Earth's carbon storage capabilities in natural sinks like forests and oceans. The past two years, 2023 and 2024, have been the hottest on record, and 2025 is projected to follow suit, becoming the third-hottest year. Climate models predicted that we could experience this level of warming, but the current temperatures are at the upper boundary of those predictions. Burgess acknowledged that while the recent acceleration in warming is a cause for concern, determining if this trend will persist over the long term requires additional data. Historical climate data from sources such as ice cores, tree rings, and coral skeletons support the notion that the Earth is currently experiencing its warmest period in the last 125,000 years. Industry insiders warn that the breach of the 1.5-degree Celsius threshold is imminent and will have severe consequences for the environment and human societies. They urge policymakers and the public to intensify efforts to reduce greenhouse gas emissions and implement adaptation strategies. Rockstrom emphasized the need for immediate and substantial action to stabilize the climate, highlighting the risks of irreversible damage. The Potsdam Institute for Climate Impact Research is renowned for its cutting-edge research on the impacts of climate change, providing crucial insights for global policy-making. In summary, the stubbornly high global temperatures in April underscore the urgency of addressing climate change. Despite the alarming projections, scientists and experts insist that continued action is essential to mitigate the worst outcomes and adapt to the changes already underway.
