World's oceans

Iranians are describing the growing isolation of the country's aviation sector, saying it increasingly cuts them off from the rest of the world. According to IranWire, reduced international flight connections and limited access to aircraft and parts have left travellers facing fewer options, higher costs and longer routes, deepening a sense of separation that people compare to having an ocean between them and the outside world.

Scientists have issued what they call their strongest warning yet about the changes transforming the world's oceans, with rising sea levels among the main concerns. The report highlights how warming waters and melting ice are accelerating shifts that threaten coastal communities worldwide. In Spain and Spanish-speaking countries, the findings are drawing attention to the risks facing low-lying coastal areas and what governments may need to do in response.

Greenpeace says the world's seas last year absorbed heat equivalent to nearly 40 times all energy humanity used, warning that fossil fuel companies and industrial meat and dairy production are driving the warming. The group highlights that 84% of global coral reefs have been hit by bleaching-level heat stress and is calling for stronger protection of the ocean and a move away from the industries it blames.

Tamil-language climate coverage is warning that a potential El Nino event in 2026 could bring destruction unlike anything seen in the past 1,000 years, sparking debate about how dangerous the phenomenon might be for the world. The claims are circulating widely among Tamil-speaking audiences concerned about extreme weather, droughts and heatwaves tied to shifting Pacific ocean temperatures.

The world's oceans absorbed a record amount of heat in 2025, warming by around 23 zettajoules, roughly 40 times humanity's total annual energy use. The finding, reported by the Guardian from ocean heat data, underscores how seas are taking up most of the excess energy trapped by greenhouse gases, accelerating warming, sea level rise and marine stress.

Satellite imagery has revealed the massive scale of routine oil pollution in the world's oceans, according to a report published by Mongabay. The findings are accompanied by an interactive map documenting oil slicks across the seas. The data suggest chronic pollution from shipping and other sources is far more widespread than previously understood.

The Copernicus Atmosphere Monitoring Service has published its latest report, finding that the world's oceans absorbed a record 23 zettajoules of heat last year, nearly 40 times humanity's total annual energy use. The report also notes that sea levels are rising faster, now reaching 4.2 millimetres per year, underlining the accelerating impact of global warming.

A new report by Mercator Ocean International finds the world's oceans are warming at an alarming pace, with far-reaching consequences for marine life, coastlines, and communities worldwide. The nonprofit, which compiled the underlying data, warns that rising ocean temperatures threaten ecosystems and the people who depend on them, prompting widespread concern among scientists and environmental observers.

The world's oceans absorbed an extra 23 zettajoules of heat last year, setting a new record for the ninth consecutive year, according to a recent report. To illustrate the scale, scientists compare it to the energy of roughly twelve Hiroshima bombs detonating every second for an entire year, underlining the pace of global warming.

The world's oceans absorbed a record amount of heat in the past year, equivalent to roughly 40 times humanity's total annual energy use, according to findings reported by The Guardian. Scientists say the thermal energy influx is driving accelerating sea level rise and ongoing ocean acidification, intensifying concerns about the pace of climate change and its effects on marine ecosystems and coastal communities.

Scientists have issued what is being described as their starkest warning yet about profound changes sweeping the world's oceans. The report highlights accelerating shifts in marine systems, with widespread coverage of the findings by international news outlets including CNN and Yahoo News. The warning points to serious consequences for marine life and coastal communities if current trends continue.

The world's oceans are absorbing record levels of heat, with scientists describing marine environments as transforming before our eyes. Rising ocean temperatures signal accelerating climate change, with consequences for sea levels, marine ecosystems and extreme weather patterns. Oceanographic reporting has highlighted the milestone, prompting renewed concern among researchers and climate watchers about the pace of global warming.

Fishermen along Latin America's Pacific coast are reporting sharply reduced catches as ocean warming intensified by El Nino pushes tuna, anchovies and other key species toward cooler waters. Half-empty nets threaten livelihoods in coastal communities that depend on some of the world's richest fishing grounds, raising concerns about food supply and export earnings across the region.

The annual Copernicus Ocean State Report, released Wednesday, documents profound changes at both ends of the planet, with Arctic waters warming rapidly, sea ice shrinking and wildlife losing habitat in polar regions. News outlets including The Japan Times are highlighting the findings, which underscore how quickly climate change is transforming the world's polar oceans.

The EU's Copernicus Marine programme has published its tenth Ocean State Report, documenting major changes to the world's seas over 40 years. Ocean waters are hotter and around 17% more acidic than four decades ago, while the Arctic has lost a Spain-sized area of sea ice per decade and the Mediterranean is experiencing more frequent marine heatwaves.
