Punishing heatwaves scorch continents as global oceans hit record June temperatures

Global average ocean temperatures reached an unprecedented high in June 2026, registering 20.98°C, surpassing previous records from 2023 and 2024. This record ocean warmth is attributed to a combination of long-term human-induced climate change and the emergence of an El Niño weather pattern. Experts predict that these temperatures are likely to climb further in the coming months as the strong El Niño develops, potentially leading to increased global temperatures, accelerated sea level rise, and more severe extreme weather events.

Concurrently, punishing heatwaves have been scorching continents, with Europe experiencing severe and widespread conditions since late May, and a second, more intense heatwave gripping the region in June. Numerous European countries, including France, Spain, and the UK, have reported broken temperature records, with some areas seeing land surface temperatures exceeding 50°C. Scientists have indicated that such an intense European heatwave would have been virtually impossible without the influence of climate change, and over 1,300 deaths in Europe have been linked to the extreme heat.

North America, particularly the United States, has also been affected by an extreme heatwave since late June 2026, placing nearly half the nation under a significant heat risk. Temperatures in many areas of the US are projected to reach between 38-43°C. These global phenomena underscore warnings from the United Nations that global temperatures are expected to remain at or near record levels in the near future, emphasizing ongoing climate challenges.
