The Impact of Climate Change on Ocean Life
Climate change is not just a land-based issue. It’s a deep-sea problem too, affecting the vast and diverse world beneath the ocean’s surface. This section will delve into the profound effects of climate change on marine biodiversity and the ecosystems that scuba divers love to explore.
Climate Change and Marine Biodiversity
Marine biodiversity refers to the variety of life forms in the ocean, from the tiniest plankton to the largest whales. This biodiversity is under threat due to climate change. Rising temperatures, ocean acidification, and sea-level rise are all consequences of climate change that can disrupt the delicate balance of marine ecosystems.
- Rising Temperatures: Warmer waters can lead to the migration of marine species to cooler areas, disrupting local ecosystems and food chains.
- Ocean Acidification: Increased carbon dioxide (CO2) absorption leads to more acidic oceans, affecting the survival of shell-forming marine life like corals and shellfish.
- Sea-Level Rise: Rising sea levels can lead to the loss of crucial coastal habitats such as mangroves and seagrass beds.
The following table summarizes the damage that rising temperature can cause to marine life.
| Marine Species | Impact of Climate Change |
| Coral | Coral bleaching due to warmer sea temperatures, difficulty building skeletons in more acidic waters |
| Shellfish | Difficulty forming shells in more acidic waters, changes in distribution due to temperature changes |
| Sea Turtles | Rising sea levels affecting nesting sites, temperature-dependent sex determination skewed by warmer sands |
| Sharks | Changes in distribution due to temperature changes, potential declines in prey species |
| Plankton | Changes in distribution and abundance due to temperature changes, base of the food chain so impacts are felt up the chain |
| Whales | Changes in distribution due to temperature changes, potential declines in prey species |
| Seagrass | Damage from more frequent and intense storms, potential benefits from increased carbon dioxide |
| Mangroves | Loss of habitat due to rising sea levels, damage from more frequent and intense storms |
Climate Change and Coral Reefs
Coral reefs, often referred to as the “rainforests of the sea,” are particularly vulnerable to climate change. These vibrant ecosystems are home to a quarter of all marine species, despite covering less than 1% of the ocean floor. Here’s how climate change is impacting these underwater paradises:
- Coral Bleaching: This occurs when corals, stressed by warm sea temperatures, expel the symbiotic algae living in their tissues, causing them to turn white. Without these algae, corals struggle to grow and reproduce, leading to a decline in reef health.
- Ocean Acidification: As mentioned earlier, more acidic waters make it harder for corals to build their calcium carbonate skeletons, slowing reef growth and making corals more susceptible to damage.
- Storm Frequency and Intensity: Climate change can lead to more frequent and intense storms, causing physical damage to coral reefs.
