The growing problem of climate change, especially global warming, is among the most pressing challenges of our time. Preserving ecosystems is essential to combat these changes and protect the planet. One promising approach is leveraging blue carbon<\/strong>, which represents the carbon stored in coastal and marine ecosystems.<\/p>\n\n\n\n

What is Blue Carbon?<\/h2>\n\n\n\n

Blue carbon refers to the carbon stored in coastal blue carbon ecosystems such as salt marshes, seagrasses, and mangroves<\/strong>. These ecosystems act as vital carbon sinks, sequestering large amounts of carbon dioxide from the atmosphere.<\/p>\n\n\n\n

Unfortunately, these ecosystems have been disappearing at an alarming rate. Over the past several decades, an estimated one-third of global coastal blue carbon ecosystems have been lost. This destruction has dire consequences, releasing between 0.15 and 1.02 billion tons of carbon<\/strong> into the atmosphere annually, thereby contributing to climate change.<\/p>\n\n\n\n

The Role of Blue Carbon Ecosystems <\/h2>\n\n\n\n

Coastal blue carbon ecosystems are invaluable not only for sequestering carbon but also for their role in maintaining biodiversity and supporting human wellbeing. However, their degradation turns them from carbon sinks into carbon sources, intensifying global warming and disrupting marine life.<\/p>\n\n\n\n

The Impact of Global Warming on Marine Ecosystems<\/h2>\n\n\n\n

One example of how global warming affects ecosystems is the rapid growth of green seaweed Ulva<\/strong>, especially in coastal regions. For instance, Ulva prolifera (U. prolifera)<\/strong> <\/em>has become the dominant species in the Yellow Sea in China, creating trans-regional disasters<\/strong> through macroalgal blooms known as green tides.<\/p>\n\n\n\n

Key Factors Influencing Ulva Growth<\/h2>\n\n\n\n

The proliferation of U. prolifera typically begins in the southern Yellow Sea during mid-April to early May, with seawater temperature<\/strong> identified as a crucial factor. At the end of green tides (mid-July to early August), massive fronds of U. prolifera sink to the seabed or remain suspended at varying depths, where they gradually decompose.<\/p>\n\n\n\n
