A poisonous fish appeared in the Black Sea: a consequence of record warming

In the summer of 2025, invasive fish species from the Red Sea emerged in the Black Sea, which had not been observed there before. According to scientists, one such species is the toxic silver pufferfish, which has already managed to adapt to the new conditions.

Researchers conclude that the appearance of these fish in the Black Sea occurred due to the impact of global warming and climate change. The rise in water temperatures has favored the survival of such species that previously lived only in the warmer waters of the Red Sea.

In 2024, record high surface temperatures were recorded both in the European region and in Ukraine. These changes are caused by global warming, which affects the climate and environment on Earth.
