El Niño, a naturally occurring climate pattern that involves unusually warm surface waters in the central and eastern equatorial Pacific Ocean can alter atmospheric circulation and significantly influence rainfall and temperatures patterns far beyond the ocean, according to the World Meteorological Organization (WMO). The WMO, the United Nations’ weather agency, says this warming is already underway and getting stronger. In an Oct. 8 update, it put the chance of an El Niño continuing through February 2027 at nearly 100%. It expects the event to be strongest in December. Regional forecasters predict a 90% chance of heavier-than-usual rain in southern Ethiopia, central to southern Somalia and northeastern Kenya between October and December 2026. Excessive rainfall could cause flooding, destroy crops, spread disease and make health services inaccessible in some areas, depending on local conditions and the season.

Action Against Hunger, an international aid organization, says families in southern Madagascar are enduring food shortages earlier than usual following a season of poor harvests. Its teams are treating children for malnourishment, as households continue to endure worsening food insecurity. Cuts in aid are also making help to tackle malnourishment harder to obtain. The United Nations International Children’s Fund (UNICEF) reported on Aug. 21 that 205 health and nutrition facilities in Somalia had closed because of funding cuts, forcing families to travel farther to find care.…This article was originally published on Mongabay

PORTLAND, Maine (AP) — The Supreme Court has declined to hear the case of a lobster fisherman who alleged the government requiring commercial fishing boats to use electronic tracking devices amounts to unreasonable search and seizure. Maine lobster fisherman Frank Thompson sued after his state began requiring all federally permitted lobstermen to install GPS trackers on their boats to collect data that will help manage the industry. Thompson appealed to the high court after losing at the appeals court level. The Supreme Court formally denied Thompson’s petition on Oct. 5. The decision allows the state to collect “critically important” data, said Carl Wilson, commissioner of the Maine Department of Marine Resources. “It will inform the lobster stock assessment, enhance offshore enforcement, and support better decision-making in a range of federal management contexts,” Wilson said in a statement. Thompson’s lawsuit raised questions about the limits of government surveillance and the ways commercial fisheries are managed. Pacific Legal Foundation, which represented Thompson, said in a Tuesday statement that “the fight over whether the government can use industry regulations to sidestep Fourth Amendment protections is far from over.” The foundation said in a blog post that the court’s decision means some 1,200 Maine lobster fishermen who hold federal permits can be tracked. However, the legal battle over government surveillance isn’t over, the foundation said. Environmental groups that have called for more commercial fishing surveillance cheered the decision. Some have said the industry needs to be monitored more closely to protect rare North Atlantic…This article was originally published on Mongabay

Fishers have caught at least 440 invasive lionfish off the coast of Porto Seguro in northeastern Brazil in recent weeks. The local government paid fishers to harvest the fish in an attempt to curb the rapid spread of a species that can decimate native fish stocks, Mariana Martins writes for Mongabay Brasil. Lionfish (Pterois volitans), which are native to the Indo-Pacific and Red Sea, have no natural predators along Brazil’s coastline and are preying upon the young of local species. The fish have already damaged coral reef ecosystems in the North Atlantic, including the Caribbean. Now they have also reportedly reached the Abrolhos reefs, the largest and richest reef system in the South Atlantic. “By preying on juveniles of commercially exploited species, there is a depletion of fish populations,” Carlos Hackradt, biologist and coordinator of the Marine Ecology and Conservation Laboratory at the Federal University of Southern Bahia, told Martins. “This brings serious consequences for the ecosystem, affects the fishing economy and harms tourism on degraded reefs.” Abrolhos is home to mushroom-shaped coral structures, locally known as chapeirões, and supports at least 90 coral and 266 fish species, including the goliath grouper (Epinephelus itajara) and blue parrotfish (Scarus coeruleus), which are nationally listed as critically endangered and endangered, respectively. Abrolhos is also the main breeding and nursing ground for humpback whales (Megaptera novaeangliae) in the Western South Atlantic. While the presence of lionfish there has been confirmed, their extent has not yet been measured. “It has only just happened,” Hackradt…This article was originally published on Mongabay
