Global warming, which is caused by the accumulation of greenhouse gases in the atmosphere from human activities (e.g., burning fossil fuels), has been contributing to gradual increases in Earth’s average surface temperature. The consequences of global warming are diverse, affecting ecosystems, weather patterns, and human societies. Key effects include rising temperatures, melting ice caps, rising sea levels, ocean acidification, extreme weather events, disruption of ecosystems, and socioeconomic consequences. Global warming leads to the higher occurrence and severity of heatwaves, affecting both natural ecosystems and human societies. In addition, global warming exacerbates glacial and polar ice cap melting, leading to coastal erosion and floods. Ocean acidification, which is caused by the uptake of excess carbon dioxide by oceans, adversely affects marine life, particularly coral reefs. Disruptions of ecosystems affect the distribution and behavior of plant and animal species, leading to changes in biodiversity and potential ecosystem collapse. Fisheries are crucial to societies globally, providing access to food, fostering economic progress, and preserving cultural traditions. They contribute to the global economy by providing employment opportunities and supporting companies involved in processing, distribution, and trade. Moreover, fisheries play a major role in scientific study, technological advancement, and understanding marine ecosystems. The effects of global warming on fisheries are complex and require a comprehensive understanding of their interconnections. This knowledge is essential for formulating adaptable strategies, sustainable fisheries management methodologies, and policies to mitigate the detrimental effects of global warming on fisheries. Collaborative efforts are necessary to reduce greenhouse gas emissions, transition to renewable energy sources, optimize energy efficiency, and adapt to climate change.
