Abstract

There are different effects of climate conditions on oceans and marine environment, most effects are negative, while there are some positive effects of these changes. Climate changes affect the oceans and marine species due to rising CO₂ levels, increased water temperatures, and low oxygen levels. The most negative effects are changes in water acidity, increased frequency and severity of marine events, and changes in the timing of seasonal events like reproduction and transition to the permanent habitat. Climate change poses significant risks to commercial fisheries, decreases the size and distribution of marine species, and affects life cycle events. Therefore, an effective strategy is required to protect oceans and the marine environment and reduce the negative impacts of climate change on fisheries and oceans.
