A global review has found that cigarette butts account for roughly 12% of litter in aquatic environments, making them one of the largest single sources of marine and freshwater pollution. The findings highlight the scale of plastic contamination from tobacco filters, which contain cellulose acetate and can release toxic chemicals as they break down in water.

Scientists report that as the Pacific Ocean warms, its water 'ages' are behaving counterintuitively: younger water is getting older while older water is getting younger. The finding points to shifting circulation and mixing patterns in the world's largest ocean, with implications for how heat and carbon are stored and moved. Researchers say the trend adds to concerns about how warming is altering ocean systems.

SpaceX's Starship completed a full-duration test flight of roughly three hours, returning through the atmosphere and splashing down in the Pacific Ocean north of Hawaii. The flight marks another step in the rocket's development campaign, with observers tracking how the vehicle handled reentry and recovery. SpaceX has not detailed the outcome of every test objective, but the splashdown confirms the ship survived to its planned end point.

Corporations frequently defend their fossil fuel emissions as insignificant compared to the global total, a framing critics call misleading. A new Guardian piece examines what the true cost of those emissions would be if their full environmental and economic impact on the oceans were properly counted, challenging the industry's 'drop in the ocean' argument and reigniting debate over corporate accountability for climate damage.

Scientists and US media are raising alarms about a slow-moving, planetary-scale Kelvin wave in the Pacific making its way toward the California coast. The ocean phenomenon could raise sea levels by up to a foot as El Niño conditions keep warm water trapped along the coastline. Observers warn the combined effect could worsen coastal erosion and flooding risks for communities already exposed to rising seas and winter storms.

SpaceX's Starship completed a test flight with a splashdown in the ocean, with the rocket appearing to burn up as it descended. The landing marks another step in the company's testing campaign for the vehicle it eventually intends to use for missions to the Moon and Mars.

New research reported by The Guardian shows Earth microbes can survive in laboratory conditions replicating the ocean beneath the ice of Enceladus, Saturn's icy moon. The findings strengthen the case that the moon's subsurface sea could be habitable, fuelling discussion among scientists and space enthusiasts about the search for life beyond Earth and future missions to Enceladus.

Two powerful hurricanes are simultaneously churning in the Pacific Ocean, drawing attention from weather watchers and news outlets. Details on their projected paths and potential impact on land or shipping routes remain limited, but the rare pairing of two major storms in the basin is prompting discussion as meteorologists track their movement and intensity.

The International Union for Conservation of Nature used the UN General Assembly and New York Climate Week to advance its agenda on nature protection, ocean conservation and climate action. The organisation says the gatherings offered a key moment to push for stronger commitments linking biodiversity and climate policy ahead of upcoming global negotiations.

A Chinese deep-ocean drilling vessel has returned to port carrying core samples collected from the South China Sea, which state media and scientists have described as scientifically precious. The specimens are expected to aid research into the seabed's geology and the region's resource potential, at a time when the South China Sea remains a focal point of both scientific work and territorial disputes involving China and its neighbours.

Maersk is highlighting how artificial intelligence is transforming global ocean shipping networks, from route optimisation to supply chain planning. The Danish shipping giant says AI adoption is changing how cargo moves across the world's maritime trade routes. The piece adds to a wider industry conversation about automation and efficiency in logistics as companies seek resilience after years of disruption.

SpaceX's Starship has returned to Earth, splashing down after its latest flight test. The rocket's descent into the ocean marks another milestone in the company's program to develop the massive spacecraft for future missions to the Moon and Mars. Reactions are focused on how the vehicle performed during reentry and landing, and what the results mean for upcoming test flights and NASA's lunar plans.

UNESCO has unveiled its ONE OCEAN installation during the UN General Assembly in New York. The installation forms part of the organization's ongoing ocean advocacy, timed to coincide with the annual gathering of world leaders where marine protection and climate issues are on the agenda.

Tropical Storm Hanna has formed in the Atlantic Ocean, according to forecasters, who say the storm currently poses no threat to land. It is being closely tracked as the season's weather systems develop, but officials report no immediate concerns for coastal areas as Hanna remains over open water.

Storms linked to the El Niño weather pattern are tearing away large chunks of the California coastline, according to reporting in The Atlantic. The article examines how intensifying ocean storms are accelerating coastal erosion, costing communities land and infrastructure along the Pacific shore. The story is being shared widely across environmental and science-focused audiences as extreme weather linked to climate patterns draws renewed attention.

NewsNation is explaining Kelvin waves, large pulses of unusually warm water that travel eastward along the equatorial Pacific beneath the surface. These events can shift ocean temperatures, strengthen storms and influence whether California sees heavy rainfall, making them closely watched indicators for forecasters tracking El Niño-style patterns and the state's water outlook.

Tropical Storm Hanna has formed in the Atlantic Ocean, becoming the latest named storm of the season, while Tropical Storm Fay has weakened back into a depression. Forecasters are tracking both systems, and attention now turns to their projected paths and any potential threats to land.

SpaceX's Starship Flight 14 completed its deorbit burn, with the ship splashing down in the Pacific Ocean as planned. The event was streamed live, drawing attention from space enthusiasts tracking the test flight's progress and performance.

The New York Times reports that the current El Niño pattern is influencing storm activity on opposite sides of the United States. The climate phenomenon, marked by warmer Pacific Ocean waters, is altering jet stream behavior and steering weather systems, shaping storm tracks for both the West and East coasts this season.

Scientists and commercial fishermen in the United States are calling on federal agencies to continue funding a deep-ocean observation system that monitors conditions far below the surface. The system provides data used for research and fishing operations, and supporters warn that cutting funding would leave a gap in understanding of deep-sea conditions and their effects on marine life and coastal economies.

Tropical Storm Hanna has formed in the Atlantic Ocean, according to reports carried by AP News and multiple local US outlets. Forecasters say the storm currently poses no threat to land, so no coastal warnings have been issued. Coverage so far focuses on tracking its position and movement, with stations from Texas to Florida passing along the advisory to audiences watching the Atlantic season.

The Atlantic reports that parts of California's coastline are literally falling into the ocean, pointing to ongoing coastal erosion along the state's edge. The piece highlights how cliffs and shoreline are collapsing as seas rise and storms wear away the land, raising questions about what this means for the communities and infrastructure built along the Pacific coast.

A new tropical storm has formed in the Atlantic Ocean, according to reports from US news outlets. Details about the storm's name, strength, and projected path have not yet been made available.
