A severe marine heatwave sweeping across the western Mediterranean has triggered widespread concern among scientists, with sea surface temperatures soaring to unprecedented levels for this time of year, threatening marine life and ecosystems across the region.
Since late June, waters around Spain’s Balearic Islands, particularly off the coast of Mallorca, have seen temperatures consistently above 30°C, a level typically not reached until much later in summer.
Portugal’s maritime authority confirmed that the Algarve region experienced a significant marine heatwave between June 28 and July 9, with sea temperatures as much as 5°C above the 20-year average.
This event is now being described as the most extreme marine heatwave recorded in the western Mediterranean during this part of the year.
Such extreme ocean temperatures are being linked to the human-driven climate crisis, which continues to intensify the frequency, duration, and severity of marine heatwaves globally.
Scientists warn that prolonged exposure to elevated sea temperatures can have devastating consequences for marine biodiversity.
The heat stress can weaken sea creatures to the point of exhaustion, preventing them from feeding, migrating, or reproducing.
In many cases, marine species may go into a non-reproductive survival mode, disrupting ecological balance and future population stability.
The Mediterranean Sea, already one of the fastest warming marine environments in the world, is home to countless unique and sensitive marine species, many of which are now at heightened risk due to the increasing temperature anomalies.
Meanwhile, across the globe in South Korea, an unrelated weather emergency unfolded as torrential rainfall caused deadly landslides and widespread flooding.
Since Wednesday, South Korea has experienced relentless rainstorms, prompting authorities to elevate landslide alerts to the highest level in multiple regions, particularly across Chungcheong.
By Saturday, at least four people were confirmed dead and two others remained missing.
In South Chungcheong province, over 500mm of rainfall had been recorded in Seosan, resulting in the evacuation of more than 7,000 people and significant property damage to at least 600 buildings.
Nearly 3,000 evacuees had still not returned to their homes by the weekend.
Further east, Tropical Storm Wipha intensified the region’s climate challenges by striking parts of Southeast Asia.
The storm initially impacted the Philippines before veering south of Taiwan and making landfall in Guangdong province, China.
As Wipha moved, it brought intense rainfall and winds to Hong Kong, where more than 110mm of rain fell in just three hours and wind gusts reached up to 100mph.
Flights were grounded by Cathay Pacific, and widespread damage was reported, including collapsed trees and scaffolding.
Wipha is expected to move toward northern Vietnam later this week, with forecasters warning of potentially severe flooding due to heavy rainfall.
These climate-related incidents underscore the growing frequency and intensity of extreme weather events globally.
As sea temperatures continue to rise and weather systems become more volatile, scientists and environmental agencies emphasize the urgent need for collective climate action to safeguard both human communities and ecosystems.
