- 1Earth microbes survive simulated Enceladus ocean conditions●Earth microbes survive simulated conditions of Saturn moon's ocean
New research reported by the Guardian shows that Earth microbes were able to survive in laboratory simulations of the ocean conditions thought to exist on Enceladus, Saturn's icy moon. The findings suggest life as we know it could potentially endure in the subsurface sea beneath the moon's ice shell, fuelling discussion about future missions to search for life there.
- 2Earth absorbs heat equal to four Hiroshima bombs every second●Climate is accumulating 4 Hiroshima atomic bombs worth of heat per second
A widely shared explanation of ocean and climate data states that the planet is accumulating heat at a rate equivalent to roughly four Hiroshima atomic bomb explosions per second. The comparison, popularised by climate scientists to make the scale of global warming graspable, is drawing attention as a stark illustration of how much excess energy greenhouse gases are trapping in Earth's systems, mostly absorbed by the oceans.

Geoscientists report that the tectonic plate system beneath the Pacific Northwest is showing signs of tearing, according to new research published via ScienceDaily. The finding concerns the Cascadia region, where the oceanic plate descends beneath North America and poses major earthquake hazards. Readers are discussing the implications for seismic risk along the US West Coast.
- 4Ocean chemistry sustained Earth's oxygen, study finds●How ocean chemistry helped life keep breathing
A new study from researchers at the University of California, Riverside finds that changes in ocean chemistry played a key role in allowing life on Earth to keep producing oxygen over billions of years. The research suggests seawater composition helped regulate the balance of elements that microbes relied on, explaining how Earth's atmosphere stayed breathable through major shifts in the planet's history.
- 5Healthy reef sounds used to restore damaged coral●From the documentary, "How To Live On Planet Earth", how a # CoralReef is being restored using sounds of healthy coral r
The documentary 'How To Live On Planet Earth' highlights a coral reef restoration method that pairs lab-grown corals with recordings of sounds from healthy reefs, which can attract fish and other marine life back to damaged areas. Viewers are sharing the clip and calling the approach inspiring, adding to wider online conversation about ocean restoration efforts.
- 6Ocean floor found to strongly influence global climate●Earth’s ocean floor has a surprisingly powerful effect on climate
New reporting highlights that Earth's ocean floor plays a far larger role in regulating the climate than previously understood. The seafloor influences how heat and carbon are stored and exchanged between the ocean and the atmosphere, processes that are central to climate models and projections. Coverage on multiple outlets is drawing attention to how much of the planet's climate machinery sits beneath the waves, largely out of sight.
- 7Bezos gives $25M for Pacific protection as climate fund nears end●Jeff Bezos gave $25M to protect the Pacific—but his climate fund still has about $7M left to spend
Jeff Bezos has pledged $25 million to protect the Pacific Ocean, according to Fortune. The grant comes from his $10 billion Earth Fund, which reporters note has only about $7 million left to distribute, raising questions about how much more climate philanthropy the fund can support and when it will be fully spent.
- 8Powerful Storms Continue to Prowl the Pacific●Powerful Storms Continue to Prowl the Pacific https://science.nasa.gov/earth/earth-observatory/powerful-storms-continue-
NASA's Earth Observatory reports that powerful storms continue to move across the Pacific Ocean, with satellite imagery tracking their progress. The images highlight the scale and intensity of the weather systems churning over the region. Observers are sharing the update as the storms remain active and closely watched for impacts on shipping, coastlines and island communities.
- 9SpaceX Starship Ends Flight Early with Fiery Pacific Splashdown●SpaceX’s Starship Makes Fiery Splashdown in Pacific Ocean After Early Return from Orbit Mission
SpaceX's Starship returned to Earth ahead of schedule, making a fiery splashdown in the Pacific Ocean during its latest orbital test mission. The early return cut short plans for the flight, though details on what prompted it have not been confirmed. The splashdown adds to the ongoing series of high-profile test flights as SpaceX continues developing the vehicle for future missions.
