Unraveling the Mediterranean Heatwave: What It Means for Our Marine Life

A recent heatwave in the Mediterranean Sea has alarmed scientists about its effects on marine life. This summer, sea surface temperatures off Mallorca have frequently surged above 30°C (86°F). Portugal’s maritime authority reported that the southern Algarve experienced a similar heatwave, with temperatures reaching up to 5°C above the average for the last two decades.

This latest marine heatwave is unprecedented for this time of year. While water temperatures above 30°C can happen in late summer, such heat this early is unusual. The high temperatures can lead to serious consequences for marine ecosystems. Many sea creatures expend energy quickly, making survival difficult. Some may even enter a survival mode that hinders reproduction.

Recent studies highlight a significant increase in marine heatwaves. According to a report by NOAA, the frequency and intensity of these heatwaves have nearly doubled over the past century due to climate change. This puts species like coral and fish at risk, potentially disrupting entire ecosystems.

In South Korea, heavy rainfall has caused devastation, leading to at least four deaths and leaving two people missing. Torrential downpours have threatened lives and properties, prompting landslide warnings in several regions.

Since the rains began, Seosan has recorded over 500mm of rainfall in just a few days. Nearly 3,000 residents have been displaced, and reports indicate damage to over 600 properties.

Meanwhile, Tropical Storm Wipha has also impacted countries in Southeast Asia. After hitting the Philippines, it brought heavy rain and strong winds to Hong Kong, causing flight cancellations and uprooted trees. The storm is now headed toward northern Vietnam, where more heavy rain is expected.

The combination of marine heatwaves and severe rainfall shows how climate change intensifies weather extremes. It serves as a reminder of our environment’s vulnerability and the urgent need for action to protect it.
