The world is experiencing significant warming, with May recently reported as the second hottest on record, according to the European Union’s climate monitoring service. The temperature remained just below the 1.5 degrees Celsius mark above preindustrial levels, a threshold critical to avoiding severe climate impacts.
Research from the Copernicus Climate Change Service shows that while waterways in many regions are heating up, the North Atlantic had especially high temperatures due to a marine heatwave. Similarly, the Mediterranean Sea recorded much warmer averages, impacting local ecosystems.
At the UN Ocean Conference in Nice, France, experts discussed these alarming trends. Rising ocean temperatures are pushing marine life to migrate. This shift disrupts food chains and threatens biodiversity. Our oceans cover 70% of the planet and play a vital role in regulating climate, but climate change is making storms more intense, leading to increased flooding and destruction.
In Europe, some areas are facing the driest conditions since 1979. Britain is grappling with its worst drought in decades, along with Denmark and the Netherlands. These changing weather patterns raise concerns about future water supply and agriculture.
Historically, May 2025 was marked by a brief dip in global temperatures, hitting 1.4°C above preindustrial levels. Carlo Buontempo, director of the Copernicus Climate Change Service, noted that this was a rare moment, as most months since early 2024 have exceeded 1.5°C, as targeted in the Paris Agreement.
While this brief respite is welcome, it may not last. Scientists predict that the 1.5°C threshold will likely be breached again. Over the last year, temperatures averaged 1.57°C above the historical benchmark. The Intergovernmental Panel on Climate Change (IPCC) warns there is a 50% chance we will exceed this goal between 2030 and 2035.
The World Meteorological Organization (WMO) has also indicated a 70% likelihood that the period from 2025 to 2029 will see average temperatures above the 1.5°C limit. Experts agree that even small increases in temperature lead to more severe weather events and ecological damage. Reports stress that limiting warming to 1.5°C, rather than 2°C, could significantly reduce catastrophic effects on our planet.
As climate change continues to unfold, the impacts will touch all aspects of our lives— from food security to biodiversity. Understanding these changes and preparing for their consequences is crucial for our future.
