Climate Change and Marine Habitats
Climate change refers to long-term alterations in temperature, precipitation patterns, and other elements of the Earth’s climate system, largely attributed to human activities, particularly the emission of greenhouse gases. According to the Intergovernmental Panel on Climate Change (IPCC), the ocean plays a crucial role in regulating the Earth’s climate, and its health is closely linked to the health of the planet (IPCC, 2020). Marine habitats, including oceans, coral reefs, and coastal regions, are profoundly impacted by climate change through various processes, which compromises the ecological integrity, productivity, and resilience of these systems. Understanding these impacts is critical, as the oceans are not only home to a vast array of biodiversity but also play a significant role in regulating climate and supporting human livelihoods. For instance, the ocean’s ability to absorb carbon dioxide and regulate the Earth’s temperature is essential for maintaining a stable climate (National Oceanic and Atmospheric Administration, 2020). Moreover, the ocean’s productivity supports the livelihoods of millions of people worldwide, providing food, income, and employment opportunities (Food and Agriculture Organization, 2018).
Key Aspects Affected by Climate Change
Temperature Increase
Rising ocean temperatures lead to habitat degradation for various marine species. For example, altering thermal regimes impacts fish species’ reproductive cycles, dispersal patterns, and food availability, disrupting marine food webs and leading to shifts in species distributions (Hansen et al., 2016). This, in turn, can have cascading effects on the entire ecosystem, leading to changes in species composition and biodiversity.
Ocean Acidification
Increased carbon dioxide absorption lowers seawater pH, creating a more acidic environment. This condition adversely affects shell-forming organisms such as corals, mollusks, and some plankton species, which struggle to maintain calcium carbonate structures vital for their survival and growth (Sabine et al., 2004). Ocean acidification can also impact the growth and development of marine organisms, leading to reduced productivity and changes in species distributions.
Deoxygenation
The warming waters hold less dissolved oxygen, exacerbating hypoxic conditions, especially in coastal areas. This leads to ‘dead zones,’ where aquatic life cannot survive, impacting fisheries and marine biodiversity (Hale et al., 2018). Deoxygenation can also have significant economic and social impacts, particularly for communities that depend on fishing and tourism.
Sea-Level Rise
Melting ice caps and thermal expansion of seawater contribute to rising sea levels, threatening coastal habitats such as mangroves, salt marshes, and coral reefs, which act as buffers against storms and support extensive marine biodiversity (IPCC, 2019). Rising sea levels can also lead to increased erosion, flooding, and saltwater intrusion, impacting human settlements and infrastructure.
