New research calls for aquatic deoxygenation to be recognized as a critical planetary process under threat. Oxygen is declining across oceans, coastal waters, rivers, lakes and streams, threatening the organisms and chemical processes that depend on it.

Scientists are sounding the alarm over a worsening situation in Earth’s oceans and freshwater systems, according to a new study that warns of “irreversible” changes our planet could be facing.
New research led by the Scripps Institution of Oceanography at UC San Diego has revealed the rapid disappearance of oxygen from bodies of sea and fresh water, leading to environmental changes that could endure for centuries if left unmitigated.
The new study, which appeared in the journal Limnology and Oceanography, argues that widespread aquatic deoxygenation—reduced levels of dissolved oxygen in oceans and coastal waters, lakes, rivers, and streams—is increasingly becoming a problem, and one that influences nine other crucial environmental processes.
These processes are all included in what is known as the Planetary Boundaries framework, a science-based tool that outlines the requirements of a safe operating space for humanity. Introduced in 2009 by Earth system scientists led by Johan Rockström, this framework identifies nine critical environmental processes that regulate Earth’s stability.
Specifically, the nine planetary boundaries outlined in this framework are climate change, biosphere integrity, land use changes, biogeochemical flow of nutrients, ocean acidification, freshwater changes, atmospheric aerosol loading, stratospheric ozone depletion, and pollution.
Now, the Scripps researchers behind the recent study say they believe dissolved oxygen levels should also be formally included in this framework.
Erica Ferrer, a Scripps Oceanography alumna and current postdoctoral scholar at UC Santa Barbara’s National Center for Ecological Analysis and Synthesis and lead author of the new study, says that her team’s work “is designed to elevate the profile of aquatic deoxygenation as a global threat and show that it does not operate in isolation.”
“The health and stability of our planet depends on the health and stability of aquatic ecosystems, which need oxygen to function normally,” Ferrer said.
Driving this growing problem, the new research says, is the excessive influx of nutrient pollution into water bodies, as well as anthropogenic warming, and changes occurring in natural ventilation systems within deep ocean waters.
With depleting oxygen levels scientists are seeing, longer-term changes to chemical and biological processes that regulate our planet’s climate are expected to occur. The decline, Ferrer and her colleagues argue, is also likely to impact a diverse range of aquatic organisms and ecosystems.
Even ocean mammals that acquire air at the surface are likely to be impacted, since deoxygenation can either cause the relocation or outright depletion of the organisms that make up their diets. This, in addition to causing severe damage to habitats and alterations to the food webs they depend on.
Ferrer and her colleague, study co-author and Scripps biological oceanographer Lisa Levin, are hopeful that their findings will encourage a deeper level of engagement on the potential ramifications of aquatic oxygen loss, and how other environmental challenges outlined in the planetary boundaries framework can act as multipliers, rather than separate existential concerns.
“Adding aquatic deoxygenation to the Planetary Boundaries framework will help us understand its impacts on Earth system stability,” Ferrer said in a statement, adding that mitigation of ocean deoxygenation impacts “represents a critical component of maintaining biodiversity and climate.”
Levin, Ferrer, and their colleagues’ study, “Abundant interactions and feedbacks between aquatic deoxygenation and the other planetary boundaries suggest ‘unsafe’ levels of oxygen loss with far‐reaching impacts,” appeared in the journal Limnology and Oceanography on June 30, 2026.

With summer heat comes pool parties, beach days, backyard cookouts, and, of course, swarms of bloodthirsty mosquitoes.
But while insect bites have always been a side effect of time spent outdoors, the species doing the biting are changing in historically temperate regions like New England. As climate change makes these areas warmer and wetter, their ranges are expanding—and any diseases they carry come with them.
In Connecticut, for example, a statewide mosquito monitoring program has detected 54 different species, including invasives like the Asian tiger mosquito, which can transmit potentially serious diseases including dengue and Zika. The mosquito’s historical territory is in hot and humid climates farther south, but it has been moving north.
As smoke from hundreds of burning wildfires spread across Canada and the United States, the first three operational satellites in the Google-backed FireSat program successfully launched into orbit. The satellites will begin providing wildfire detection capable of spotting even small fires in the United States, Australia, and Europe before the end of the year.
The launch of the microsatellites aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California on July 7, 2026 marks a transition to “initial operational capability” for the FireSat constellation managed by the nonprofit Earth Fire Alliance. After a three-month testing period, the three satellites will begin actively providing data to fire agencies while covering every fire-prone region on Earth at least twice per day.
FireSat represents the first satellite constellation purpose-built for detecting wildfires, including spotting smaller fires that other satellites may miss. The satellites were designed by California-based satellite manufacturer Muon Space and have received over $15 million from Google to support initial deployment. Other notable financial supporters include the Bezos Earth Fund that committed $26 million.

Fresh off a month that saw all but five states mired in severe drought, the US is reeling from multiple crises of national proportions.
First, there’s the record-breaking heat dome which is currently baking most of the continental US. According to the Guardian, over 100 million Americans are currently living under extreme heat warnings, forecasted to persist well into the weekend.
At the same time, the country is being smoked out by dozens of wildfires across North America, a situation the heat wave isn’t exactly helping. On top of that, smoke from over 800 blazes in Canada is helping choke out the US Midwest and North-East, making the air hazardous to breathe.
Things aren’t necessarily any prettier outside of the smoke-zone — just wetter. Communities situated around the Guadalupe River in Texas are reeling after near endless rainfall triggered massive floods across the state for the second year in a row.
So far, at least one person is dead, while thousands have been forced to evacuate. At least 57 counties representing over six million people were placed under flood watches over the past few days. With even more rain on the horizon, it remains to be seen when Texas will get relief from the torrential downfalls.
Stepping back, it’s clear this cascade of extremes isn’t happening in a vacuum. The overlapping wildfires, floods, and heat waves are all being amplified by the same climate forces: a rapidly warming planet, fueled in no small part by skyrocketing carbon emissions from the US itself.
All in all, it’s been an action-packed summer as the El Niño cycle rolls on — and unfortunately, the devastation is far from over.

While they were at it, the Trump administration also ripped up a project that would have vastly improved the country’s ability to monitor wildfires. The GeoXO program was a project originally encompassing six satellites that would greatly improve the resolution available to the National Oceanic and Atmospheric Administration to monitor atmospheric conditions like wildfire smoke, as well as weather events like lightning strikes, and climate observations such as color changes in the ocean’s surface.
The six satellites were meant to encompass three regions split between the US West, Central, and East. Starting in April 2025, however, the Trump administration directed the NOAA to make drastic cuts to GeoXO. These included cutting two satellites from the mission altogether — scrapping the central observation region entirely — and canceling major contracts for existing GeoXO instruments. The purported goal was to refocus the program on a “core weather mission,” as opposed to long-term climate monitoring, following the administration’s broader attacks on any effort to mitigate or even mention climate change.
One of those cancelled instruments, the GeoXO Atmospheric Composition device, was a high-resolution spectrometer designed to give the NOAA advanced capabilities to monitor air pollutants, like ozone, nitrogen dioxide, formaldehyde, and excess particulate matter. In the long term, the tool would have helped scientists paint a clearer picture of how particular weather events relate to broader climate shifts, an NOAA report explains.
Of course, the timing of the cancellation couldn’t have been worse. Huge swaths of the United States and Canada are currently being smoked out by noxious fumes emanating from hundreds of wildfires across North America.
Though the GeoXO program wouldn’t have gone live until the 2030s, Trump’s decision represents a devastating loss for our future ability to monitor this exact phenomenon, which is becoming something of an annual tradition for millions of people.
As Susan Anenberg, chair of environmental and occupational health at George Washington University observed, the NOAA “had spent years planning an air pollution instrument on the GeoXO satellite which would provide near-real-time, location-specific data on smoke levels, giving people the information they need to avoid exposure.”
Anenberg explained that the public health benefits this kind of monitoring would provide “could amount to about $13 billion per year.”
“As smoke events happen more often,” Anenberg continued, “we need more data, not less.”

A leaf-eared mouse living more than 6,700 meters (22,000 feet) above sea level in the Andes has shattered assumptions about where mammals can survive. Near the summit of an Andean volcano, where the air contains barely half as much oxygen as it does at sea level, scientists found something that should not have been there: [...]Climate change is being driven largely by the greenhouse gases we've pumped into the atmosphere, which trap more of the Sun's energy there. That added energy increases the odds of extreme events: longer, more intense heat waves and droughts, interspersed with excessive precipitation. But these sorts of events have happened in the past—how can we tell if any given weather disaster has been made more likely by the climate?
It's a question with implications for everything from building codes to disaster preparedness. And there's some good news: According to a report released by the US National Academies of Science on Thursday, the field of climate attribution is growing increasingly mature and can answer some questions for us with far greater confidence than it could just a decade ago. The report also notes that there are still important limits and suggests steps to address them.
Overall, this makes it clear that climate attribution is normal, mainstream science. And the fossil fuel industry views that as a problem, as it could make it easier to hold companies liable for damages. This has triggered a backlash that has Republicans in Congress and state governments threatening the National Academies' funding.

Climate change is poised to reshuffle the reliability problem facing decarbonized power systems, according to a new study that links weather extremes, long-term climate projections, and real-world infrastructure constraints. As grids rely more heavily on wind and solar, they become sensitive not just to the amount of renewable capacity installed, but to where that capacity is sited relative to transmission lines, load centers, and the local meteorological patterns that govern output.
Using high-resolution climate projections at 12-km scale, the researchers examined how future conditions could alter both renewable generation and electricity demand across two distinct US regions: New England and Texas. They then coupled these climate inputs with an optimization model operating at the county level, allowing the team to test how system design choices—particularly spatial siting of wind and solar and the presence of transmission bottlenecks—affect long-run adequacy.
The results suggest a sharp increase in resource inadequacy risk by mid-century. In both regions, climate change can drive prolonged periods of low renewable generation, which occur when meteorological conditions reduce wind and solar output while demand simultaneously rises. For Texas, the study finds the frequency of inadequacy events could increase dramatically—up to fivefold—if planning proceeds using non-climate-informed assumptions.
Crucially, the work shows that these risks are not determined by aggregate capacity targets alone. Fine-scale siting decisions can lock the system into unfavorable “weather-resource–grid” pairings, amplifying periods when local supply falls short and transmission limits prevent imports from compensating.
Yet the study also offers a pathway to resilience. Climate-informed planning can mitigate the emerging adequacy threat at relatively modest cost. Texas, for example, can maintain near-zero marginal investment cost by shifting wind capacity westward, improving alignment with future wind patterns and reducing reliance on constrained transfers.
New England requires a different strategy. The region faces a higher investment need—about a 2.34% increase—achieved through targeted solar and transmission expansion closer to load centers. This approach helps buffer localized shortfalls during future, climate-driven demand and renewable output mismatches.
Overall, the study argues that achieving climate-resilient decarbonization means moving beyond simple build-out schedules. Instead, it calls for high-resolution, climate-aware spatial planning that reveals siting opportunities invisible to coarse models—turning reliability from a static design metric into a dynamic, region-specific forecast problem.
