Warm oceans refer to areas of the sea where the surface temperature is higher than average, typically above 25 degrees Celsius (77 degrees Fahrenheit). These temperatures can influence weather patterns, marine ecosystems, and the distribution of marine life. Warm oceans are often found in tropical regions and can be affected by phenomena such as El Niño. The warmth of ocean waters can lead to coral bleaching, which occurs when corals expel the algae living in their tissues, causing them to turn white and become more vulnerable. Additionally, warm oceans can intensify storms and hurricanes, making them more powerful and potentially more destructive.
