The world’s oceans experienced the second-highest recorded temperatures for May, with an average sea surface temperature of 20.79°C, raising concerns about their ability to absorb carbon dioxide amidst rising CO₂ levels peaking at 426 parts per million. Scientists warn that the ocean’s capacity to mitigate climate change may diminish due to increasing marine heatwaves and long-term warming trends, particularly in the North Atlantic. Recent data indicates that while surface temperatures remain high, May marked a slight decrease in temperature rise relative to pre-industrial levels, with varying weather patterns across different regions.
