In recent months, the UK has been experiencing an exceptional marine heatwave, contributing to record-breaking sea surface temperatures. In May 2023, temperatures were reported to be approximately 1.6°C above the 1961-1990 average, marking the warmest May since records began in 1850. Some regions, particularly in the North Atlantic, have shown anomalies of up to four degrees higher than normal, raising alarms among scientists about the long-term impacts on marine ecosystems.

This marine heatwave, classified as “moderate” in parts of the East coast and “extreme” elsewhere, has extended significantly beyond the expected duration. Such prolonged warmth, defined as marine heatwaves wherein temperatures exceed seasonal thresholds for more than five consecutive days, has persisted for weeks. With historical temperature data suggesting these conditions have not been recorded in 45 years, there is an urgent focus on how rising sea temperatures impact marine life, especially regarding breeding patterns and ecosystem balance.

The consequences of such heat anomalies are likely to include harmful algal blooms and increased jellyfish populations, which can disrupt local marine environments. These alarming shifts are attributed largely to human-induced climate change, with scientists warning that these heatwaves will become more frequent and intense in the future. As highlighted by experts, the pivotal question remains: can our seas endure the ongoing impact of human activity?

This question is at the core of the Sainsbury Centre’s latest initiative, “Can the Seas Survive Us?”, which features a series of exhibitions aimed at raising awareness about the interconnectedness of climate change and marine health. The programme includes three concurrent exhibitions – “A World of Water”, “Darwin in Paradise Camp: Yuki Kihara”, and “Sea Inside.” Running until October 26, 2025, the exhibitions draw attention to the urgent need for collective action to mitigate the impacts of climate change on marine ecosystems.

In a recent interview with artist Josh Kline, featured in the Sainsbury Centre’s Channel, he boldly stated, “Human beings will have to adapt to a more dangerous world with higher seas, more fires, and less arable land.” Kline’s work, which imagines dystopian futures affected by rising waters, reflects the harsh reality scientists now accept: radical climate change is unavoidable.

Moving forward, the Sainsbury Centre’s exhibitions not only spotlight the challenges facing our oceans but also seek to inspire action to restore marine habitats. As the discussions surrounding climate change intensify, the artworks presented offer a unique lens through which to view the relationship between humanity and the marine world. The message is clear: urgent action is required to foster a future where sea life can coexist with the realities of climate change, challenging us to rethink how we interact with our planet’s most vital resources.

The Sainsbury Centre’s programme invites visitors to engage with these themes critically, considering how our choices can influence the future of marine ecosystems. As global temperatures continue to rise, the question remains central: how can we harness this awareness to inspire meaningful change in our relationship with the seas?
