One of our department’s academics, Prof. Dr. Coşkun Erüz, participated in TRT Trabzon Radio’s “From Life” program, where he extensively discussed the effects of increasing seawater temperatures on marine ecosystems. The program highlighted critical topics such as marine sciences, environmental awareness, and climate change, aiming to raise public consciousness in these areas.

The Role of Oceans in Our Planet

Prof. Dr. Erüz emphasized the crucial role of oceans in shaping Earth's climate system. Oceans, which cover approximately two-thirds of the Earth's surface, are among the key components that regulate global climate. The warming of oceans affects atmospheric temperatures and consequently determines global climate patterns. Changes in ocean temperatures impact not only marine ecosystems but also the entire planet's climate balance. Oceans absorb a significant portion of solar radiation and store part of the heat in the atmosphere, stabilizing global climate conditions.

Impacts of Rising Sea Water Temperatures

Prof. Dr. Erüz pointed out that the increase in seawater temperatures poses a significant threat to marine life cycles and the equilibrium of marine ecosystems. The warming of oceans enhances water evaporation, raising humidity levels in the atmosphere, which in turn alters precipitation patterns and triggers extreme weather events such as heavy rainfall and droughts. Using the Black Sea as an example, he noted that while rising temperatures have not yet caused major disruptions in the region, long-term consequences could include species migration or loss due to an inability to adapt. A temperature rise of 1-2 degrees Celsius in the Black Sea could threaten the structure and biodiversity of the local marine ecosystem.

The Connection Between Oceans, Freshwater, and Pollution

The relationship between freshwater sources and marine pollution was another key topic. Prof. Dr. Erüz explained how pollutants from freshwater sources entering the oceans harm marine ecosystems and can ultimately affect human health. Agricultural waste, including nitrates and pesticides, often reaches the seas, leading to toxic effects within ecosystems. Additionally, the rapid warming of the seas alters ocean currents and weather patterns, contributing to long-term changes in the global climate system.

Regional and Global Impacts

Prof. Dr. Erüz stated that regional weather conditions are directly influenced by seawater temperatures. For instance, temperature increases in semi-enclosed seas like the Black Sea significantly affect local climate and weather patterns. However, these changes are not just local concerns but part of a global issue. Even minor atmospheric changes can trigger large-scale alterations in oceanic systems, ultimately impacting the global climate. Therefore, efforts to address climate change and rising seawater temperatures should be a shared responsibility worldwide.

Conclusions and Future Perspectives

Prof. Dr. Erüz emphasized that while some marine species may currently tolerate rising temperatures, prolonged changes could lead to severe disruptions in marine ecosystems and shifts in species distributions. Sustainable marine management and environmental protection measures are essential to preserving ecosystem health.

Additionally, he highlighted the importance of global cooperation in combating climate change and marine pollution. Raising public awareness and promoting education on these issues will play a vital role in mitigating future impacts. He stressed the need for continued scientific research and the implementation of international policies based on global cooperation to protect marine ecosystems in the coming years.
