World's Seas Hit Record High Temperature in July

The world's seas have recorded their highest temperatures for any July, with severe marine heatwaves affecting European waters.

According to the European Union's Copernicus Climate Change Service, the global average sea surface temperature outside the polar regions surpassed the previous July record set in 2023.

Surface air temperatures globally in July 2026 were only 0.01C cooler than in July 2024, making them the joint-second warmest Julys on record. Western Europe experienced its hottest June-July period on record, with extreme temperatures contributing to wildfires across parts of the Mediterranean.

The first two months of summer 2026 were 2.79C hotter than usual, surpassing the previous record set four years ago. Central Europe has also been hit by a heatwave, with national temperature records falling in countries including Austria and Slovakia.

The prolonged heat has dried vegetation and increased conditions conducive to fires. Climate scientist Samantha Burgess described the summer as 'a clear example' of climate breakdown intensifying interconnected extremes.

Widespread dry conditions observed in May and June worsened in July, with exceptionally low rainfall and soil moisture recorded across much of western Europe. France, Spain and parts of Germany and the UK were among the affected regions.

Low river flows disrupted water supplies, irrigation and power generation, including in downstream countries. A shortage of cooling water forced two coal-fired power plants in Poland to shut last week.

The heat and drought pose major environmental threats to Europe's economy, with early estimates indicating that the June heat caused €2 billion in crop losses for grain farmers.

The record temperatures and heatwaves have significant implications for the environment and human health. As the world continues to experience rising temperatures, it is essential to take action to mitigate the effects of climate change.

In conclusion, the record high temperatures in the world's seas and the severe heatwaves in Europe are a stark reminder of the urgent need to address climate change. The impacts of climate change are far-reaching and devastating, and it is crucial that we take immediate action to reduce our carbon footprint and transition to renewable energy sources.

The effects of climate change are not limited to the environment; they also have significant economic and social implications. The heatwaves and droughts have already caused significant damage to crops and infrastructure, and it is essential that we take steps to adapt to the changing climate and build resilience in our communities.

As the world continues to experience the impacts of climate change, it is essential that we work together to find solutions and take action to mitigate its effects. The record high temperatures in the world's seas and the severe heatwaves in Europe are a wake-up call, and it is crucial that we respond with urgency and determination.
