Climate Change

Climate change poses a significant threat to marine life in Nigeria.

There are various adverse effects on marine ecosystems.

One of the key impacts of climate change on marine life is ocean acidification.

Ocean acidification occurs when the ocean absorbs carbon dioxide from the atmosphere.

Rising sea levels are also a major consequence of climate change.

This rise results from the melting of polar ice caps and glaciers.

In Nigeria, this phenomenon can lead to coastal erosion, flooding, and habitat loss for marine species.

Another consequence of climate change on marine ecosystems is coral bleaching.

Coral bleaching is a process in which corals expel the algae living in their tissues.

This expulsion causes corals to turn white and potentially die.

Coral reefs are crucial habitats for various marine species.

The decline of coral reefs due to climate change poses a threat to biodiversity in Nigeria.

Specific Examples of Climate Change Impacts on Marine Ecosystems

• Loss of coral reefs due to bleaching events, leading to a decline in fish populations.
