Unusual marine heat waves are affecting major ocean basins globally, prompting scientists to introduce a new term: super marine heat waves. According to Boyin Huang, a NOAA oceanographer, these heat waves present unprecedented sea surface temperatures that ecosystems have never experienced before.
An intense marine heat wave was observed off the coasts of the UK and Ireland starting in April, with temperatures rising significantly earlier in the season than usual. Similarly, Australia's renowned coral reefs have suffered due to heat waves on both coasts.
As the consequences of climate change grow, the oceans are absorbing excess heat trapped by greenhouse gases, leading to dramatic impacts on marine life, sea levels, and weather patterns. Coral reefs are particularly vulnerable; nearly 84% of these delicate ecosystems faced bleaching-level heat stress between January 2023 and March 2025.
Last year marked the hottest on record, resulting in accelerated sea level rise attributed primarily to thermal expansion from warmer ocean water, rather than traditional causes such as melting ice sheets.
The situation underscores the critical need to address climate change and its repercussions on the world's oceans, ensuring both ecological balance and the survival of marine species.
