France - Un feu a pris en fin d'après-midi mercredi à proximité du sentier de randonnée GR20, l'incendie qui a déjà ravagé 150 hectares mobilise trois Canadair et 200 hommes.

Un incendie a ravagé 150 hectares depuis mercredi après-midi dans la commune de Palneca (Corse-du-Sud), dans le centre de l'île à l'Est d'Ajaccio, à proximité de plusieurs sentiers de randonnée dont le GR20, qui ont été fermés partiellement, a appris l'AFP auprès des pompiers. Par ailleurs, l'île est en vigilance orange canicule.

D'importants moyens déployés. L'opération est complexe du fait de la configuration des lieux, cette forêt de pins, dans un relief compliqué de moyenne montagne, est inaccessible à pied. Le feu court actuellement sur 7 km de lisières, ce qui laisse présager un chantier de plusieurs jours pour les pompiers. Selon eux, la priorité est de créer une barrière de retardant sur la ligne de crête, à la limite des deux départements, afin que l'incendie ne continue pas sa progression vers la Haute-Corse.

À la mi-journée, l'incendie avançait sur certains fronts et mobilisait quatre Tracker, trois Canadair, un détachement d'intervention héliporté ainsi qu'environ 200 hommes au sol.

Randonneurs et baigneurs évacués. Les flammes traversant des sentiers de randonnée - le célèbre GR20, mais aussi le Mare Monti et le Mare a Mare -, ceux-ci ont été fermés au niveau du sinistre et les pompiers ont demandé aux refuges environnants de garder les randonneurs ou de les rediriger vers d'autres chemins. Mercredi en fin d'après-midi, une dizaine de randonneurs et de personnes qui se baignaient dans la rivière en contrebas de la forêt avaient été évacués par hélicoptère.

Trois autres départs de feux. Alors que l'île est placée en vigilance orange canicule depuis mardi comme onze autres départements du Sud-Est et que les températures atteignent des records, quatre départs de feu ont eu lieu mercredi en Corse-du-Sud. Environ 80 hectares ont brûlé à Appietto, à une dizaine de kilomètres au-dessus d'Ajaccio, dans un incendie qui a menacé des habitations mais est désormais sous contrôle.

Un incendie maîtrisé à Ocana. Un départ de feu a également touché le village d'Ocana, à une vingtaine de kilomètres à l'Est d'Ajaccio, vers trois heures du matin jeudi. Des maisons ont été menacées, mais l'incendie est désormais maîtrisé après avoir parcouru trois hectares.

Corse-du-Sud: 150 hectares burned in Palneca, three other starts

A fire late afternoon on Wednesday near the GR20 hiking trail, the fire that already ravaged 150 hectares mobilizes three Canadair and 200 men.

A fire has ravaged 150 hectares since Wednesday afternoon in the town of Palneca (Southern Corsica), in the center of the island to the east of Ajaccio, near several hiking trails including the GR20, Which were partially closed, AFP learned from the firefighters. Moreover, the island is in vigilance orange heat wave.

Significant resources deployed. The operation is complex because of the configuration of the places, this pine forest, in a complicated relief of medium mountain, is inaccessible on foot. The fire is currently running on 7 km of edges, which suggests a site of several days for firefighters. According to them, the priority is to create a delay barrier on the crest line, at the limit of the two departments, so that the fire does not continue its progression towards Upper Corsica.

At mid-day, the fire was advancing on certain fronts and mobilized four Trackers, three Canadair, a helicopter intervention detachment and about 200 ground troops.

Hikers and bathers evacuated. Flames crossing hiking trails - the famous GR20, but also the Mare Monti and the Mare a Mare - have been closed at the level of the disaster and the firemen have asked the surrounding refuges to keep the hikers or to redirect them To other paths. Wednesday afternoon, a dozen hikers and people bathing in the river below the forest had been evacuated by helicopter.

Three more starts of fire. While the island is placed in vigilance orange heat wave since Tuesday like eleven other départements of the South-East and that the temperatures reach the records, four starts of fire took place on Wednesday in Corse-du-Sud. Around 80 hectares burned in Appietto, about ten kilometers above Ajaccio, in a fire that threatened homes but is now under control.

A controlled fire in Ocana. A fire start also hit the village of Ocana, about twenty kilometers east of Ajaccio, around three in the morning on Thursday. Houses have been threatened, but the fire is now under control after crossing three hectares.

An international team of climate researchers from the US, South Korea and the UK has developed a new wildfire and drought prediction model for southwestern North America. Extending far beyond the current seasonal forecast, this study published in the journal Scientific Reports could benefit the economies with a variety of applications in agriculture, water management and forestry.

Over the past 15 years, California and neighboring regions have experienced heightened conditions and an increase in numbers with considerable impacts on human livelihoods, agriculture, and terrestrial ecosystems. This new research shows that in addition to a discernible contribution from natural forcings and human-induced global warming, the large-scale difference between Atlantic and Pacific ocean temperatures plays a fundamental role in causing droughts, and enhancing wildfire risks.

"Our results document that a combination of processes is at work. Through an ensemble modeling approach, we were able to show that without anthropogenic effects, the droughts in the southwestern United States would have been less severe," says co-author Axel Timmermann, Director of the newly founded IBS Center for Climate Physics, within the Institute for Basics Science (IBS), and Distinguished Professor at Pusan National University in South Korea. "By prescribing the effects of man-made climate change and observed global ocean temperatures, our model can reproduce the observed shifts in weather patterns and wildfire occurrences."
