New figures circulating online state that the world's oceans and atmosphere are trapping heat at a rate equivalent to the energy released by four Hiroshima atomic bombs every second. The comparison is being used to make the scale of global warming tangible, with commenters expressing alarm that warming has accelerated well beyond earlier estimates of one to two bombs per second.

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.

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.

The world's oceans absorbed a record amount of heat, equivalent to roughly 40 times humanity's total annual energy use. Scientists report the thermal energy injection is driving accelerating sea level rise and continued ocean acidification, with the findings renewing concern about the pace of global warming and its long-term effects on marine ecosystems and coastlines.

Greenpeace reports that last year the world's oceans absorbed heat equivalent to almost 40 times all energy humanity consumed, warning that 84% of global coral reefs have been hit by bleaching-level heat stress. The group blames fossil fuel corporations and industrial meat and dairy production for driving the warming, and is calling for action to protect the ocean.

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.

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 absorbed an extra 23 zettajoules of heat last year, setting a new record for the ninth consecutive year, according to a report. Scientists put the figure in perspective by comparing it to the energy of 12 Hiroshima bombs detonating every second for a year, underlining the scale of ocean warming driven by climate change.

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. The finding, reported by The Guardian, underlines the pace of global warming, with scientists warning that record ocean heat drives stronger storms, rising sea levels and marine heatwaves. Researchers say the continued rise in ocean heat content shows the planet's energy imbalance is worsening despite international climate pledges.

A newly released ocean report warns that seas are rising, ocean temperatures are climbing and acidification is worsening, with mounting consequences for coastal communities and marine life. Coverage highlights the combined pressures on the world's oceans and the growing urgency of climate action to limit further damage.

New reporting highlights that the world's oceans have become 20% more acidic since 1985. The increase is driven by seawater absorbing carbon dioxide from the atmosphere, a process that threatens marine life such as corals and shellfish. The finding is renewing discussion about the pace of ocean acidification and the urgency of cutting emissions.

The world's oceans absorbed a record amount of heat in 2025, taking in around 23 zettajoules — equivalent to roughly 40 times humanity's total annual energy use. Scientists link the warming to accelerating sea-level rise, as thermal expansion pushes water levels higher. The findings renew concern about the pace of climate change and the oceans' diminishing capacity to buffer global warming.

New findings show the world's oceans are becoming saltier and more acidic as marine heatwaves drive what researchers describe as a 'profound change' in ocean chemistry. Rising temperatures are intensifying evaporation in salty regions while increased carbon absorption is acidifying waters, threatening marine ecosystems, fisheries and coastal communities that depend on them.

A piece by student intern Arya Adhye examines the disappearance of the Great Barrier Reef, arguing that Australia's iconic coral system is vanishing at an alarming rate. The article, published by the Sierra Club, frames the reef's decline as a worsening environmental crisis tied to ocean warming, adding to a growing body of concern about the fate of the world's largest coral reef.

The world's oceans absorbed a record 23 zettajoules of heat last year, the highest annual figure ever measured, according to reporting by The Guardian. The finding underlines the scale of global warming, since the seas take up the vast majority of excess heat trapped by greenhouse gases. Scientists say rising ocean temperatures drive sea level rise, coral bleaching and more extreme weather.

A new report finds the world's seas took in a record-breaking 23 zettajoules of heat in 2025, leaving ocean waters hotter, higher and less hospitable to marine life. Scientists say the figures underline the accelerating pace of ocean warming driven by climate change, with rising sea levels and stressed ecosystems among the consequences being highlighted.

Scientists report that the world's oceans reached their highest recorded temperatures in 2025, with warming likened to the energy of a dozen Hiroshima bombs released every second. The record heat is raising alarm about coral bleaching, stronger storms, sea-level rise and disruption to marine ecosystems, with researchers urging faster cuts to greenhouse gas emissions.

The EU's Ocean State Report 10 has found that marine heatwaves in the Mediterranean have reached their highest level in two decades. The finding points to intensifying warming in one of the world's most vulnerable seas, with scientists warning of consequences for marine ecosystems, fisheries and coastal communities across the region.

The latest Copernicus Climate Change Service report finds that the heat stored in the world's oceans has reached its highest recorded level. Ocean heat content is a key indicator of climate change, since the seas absorb most of the excess heat trapped by greenhouse gases. Scientists say the record underscores the continued warming of the planet and its consequences for marine life, sea levels and extreme weather.

New analysis shows the world's oceans absorbed a record amount of heat in 2025, equivalent to roughly 23 zettajoules, or about 40 times humanity's total annual energy use. Scientists say the finding confirms oceans are absorbing the vast majority of excess heat trapped by greenhouse gases, with rising water temperatures driving sea level rise, coral bleaching and more intense storms.
