Early Mediterranean warming: a concerning climate signal for summer 2026
via Business News3 min read
The Mediterranean basin is experiencing an unusually large thermal anomaly for this time of year, with surface temperatures in several areas of the western Mediterranean five to six degrees above seasonal averages, according to the European climate monitoring program Copernicus. Environmental engineer and climate expert Hamdi Hached stated on June 8, 2026, that this warming is premature, having begun in late May, whereas marine temperatures typically peak at the end of summer. This increase is linked to a recent heatwave in Western Europe, where Spain and Portugal recorded atmospheric temperatures of 37 to 40 degrees Celsius, amplified by a thermal dome. The Mediterranean Sea absorbed significant thermal energy, leading to a rapid rise in its surface temperature. Hached expressed concern that the summer season is starting with an already significantly warmed sea, which could lead to longer, more frequent, and more intense marine heatwaves. He noted that in 2025, parts of the western Mediterranean, off Algeria and Spain, saw marine temperatures exceed 30 degrees Celsius for the first time, indicating a worrying trend rather than an isolated event. Beyond marine ecosystems, a warmer sea acts as a large reservoir of energy and humidity, potentially fueling more violent weather events such as intense rains and storms when cooler air masses pass over it. Hached suggested that several recent significant weather events in the Mediterranean region could be linked to accumulated heat

President Kaïs Saïed chaired a meeting on the afternoon of July 22, 2026, at the Carthage Palace, focusing on water and electricity cuts and fires affecting several regions of the country. The meeting included the Minister of Interior, Khaled Nouri; the Minister of Equipment, Housing, and acting Minister of Industry, Mines, and Energy, Salah Zouari; the Minister of Agriculture, Water Resources, and Fisheries, Ezzeddine Ben Cheikh; the CEO of the Tunisian Electricity and Gas Company Steg, Fayçal Trifa; the CEO of the National Water Exploitation and Distribution Company Sonede, Abdelhamid Mnaja; and the Director General of the National Civil Protection Office, Colonel Mohamed Rached Souissi. Kaïs Saïed stated he was closely monitoring the situation nationwide, describing the recent water and electricity cuts and fires as "abnormal phenomena." He affirmed that the state would not remain passive against those seeking to harm citizens and incite tensions. The head of state addressed water and electricity distribution interruptions exceeding 24 hours in several regions, deeming the situation unacceptable and calling for an immediate end. He also stressed the need to inform citizens in advance of scheduled cuts and to choose appropriate times when such cuts are unavoidable. Kaïs Saïed commended the efforts of Civil Protection units, in coordination with military, security, and administrative structures, for their rapid and effective interventions in controlling fires. He concluded b
Wajih Dhokkar, a doctor and member of the Tunisian Organization of Young Doctors, stated on Wednesday, July 22, 2026, that the organization estimates between 150 and 200 deaths due to heatstroke in recent days. These figures are based on information gathered from young doctors in public hospitals, as the Ministry of Health has not released official data. Dhokkar noted that deaths occurred in various settings, including emergency services, at home with SAMU intervention, and among hospitalized patients whose conditions worsened due to thermal stress, requiring transfer to intensive care. He also mentioned that some hospitals, such as Charles-Nicolle Hospital in Tunis, experienced power outages affecting certain medical services, though priority services like emergencies and intensive care were spared. Dhokkar criticized the lack of official communication from the Ministry of Health regarding the human toll of the heatwave, calling it a significant failure to citizens' right to information. He also highlighted the absence of an official declaration of a health emergency and clear public guidelines, which he believes is inadequate given the severity of the situation. This statement follows a call from the Tunisian Organization of Young Doctors for authorities to establish a national crisis unit, publish health impact data, and reinforce healthcare facilities. The Ministry of Health has not yet released any detailed official report on deaths or hospitalizations related to the hea
The Tunisian Electricity and Gas Company Steg has published a technical framework on July 22, 2026, officially allowing the integration of battery energy storage systems BESS into low-voltage grid-connected photovoltaic installations. This development applies to both individuals and professionals with solar installations connected to the national grid, aiming to improve energy management. This move comes as Tunisia faces an exceptional heatwave, leading to record electricity consumption and repeated power outages due to the strain on a grid largely dependent on thermal power plants. Battery storage is seen as a way to enhance the resilience of photovoltaic installations and reduce reliance on the grid during peak demand or outages. The new framework recognizes the role of batteries in optimizing self-consumption and providing backup power when the grid is unavailable. Batteries can store energy produced during the day for use in the evening or during power interruptions, with the document also allowing for hybrid inverters. Strict technical requirements are in place, including international safety and performance standards for equipment and detailed technical documentation from installers. Special attention is given to fire prevention, ventilation, and cooling conditions. For systems exceeding 100 kWh, factory tests are required to ensure reliability. The framework also mandates compatibility between batteries and inverters and requires a Battery Management System BMS for con
