The ongoing conflict in the Middle East is creating ripple effects far beyond rising gas prices, with global food security now at serious risk due to disrupted fertilizer supplies. The largely blocked Strait of Hormuz has become what UN Food and Agriculture Organization chief economist Máximo Torero Cullen calls “a critical failure point for global food security.”

Approximately one-third of the world’s seaborne fertilizer trade typically passes through this strategic waterway, making the current blockade a significant threat to agricultural production worldwide. When fertilizer supplies are disrupted, crop yields can plummet, potentially leading to food shortages and price spikes that disproportionately affect vulnerable populations.

The crisis highlights the fragility of global supply chains and the interconnected nature of modern agriculture. Many countries depend heavily on imported fertilizers to maintain their food production levels, leaving them exposed when geopolitical conflicts disrupt trade routes.

However, experts suggest this crisis could serve as a catalyst for positive change. Transitioning to more sustainable agricultural practices could help build resilience against both geopolitical disruptions and climate-related threats. Strategies such as regenerative farming, reduced chemical dependency, and diversified supply chains could help insulate food systems from future shocks while simultaneously reducing environmental impact.

For tens of millions of years, mangrove forests have stood as nature’s ultimate survivors, thriving where land meets sea in some of Earth’s harshest conditions. These remarkable trees have mastered the art of living in saltwater, creating vast coastal ecosystems that serve as powerful weapons against climate change by storing enormous amounts of carbon in their roots, trunks, and surrounding soil.

Beyond their role as carbon storage champions, mangroves form living shields that protect millions of people from storm surges and coastal flooding. Their intricate root systems act as natural breakwaters, absorbing wave energy and preventing erosion that could devastate coastal communities. These forests also support incredible biodiversity, serving as nurseries for countless fish species and providing habitat for birds, reptiles, and marine life.

However, new research reveals a troubling paradox: while mangroves are among our most effective natural allies in fighting climate change, they may not be able to withstand the very problem they help solve. Rising sea levels driven by global warming threaten to push even these resilient ecosystems beyond their survival threshold. The modeling study suggests that the rate of sea level rise may soon outpace the mangroves’ ability to adapt, potentially triggering a devastating feedback loop where the loss of these forests releases stored carbon back into the atmosphere.

This threat represents more than just the loss of trees—it signals the potential collapse of a critical natural infrastructure that protects both climate stability and human communities worldwide.

Duke Energy is poised to receive $28.4 million in federal taxpayer funding to upgrade two aging coal-fired power units at its Roxboro plant in Person County, North Carolina. The federal grant would be supplemented by an additional $44 million from ratepayer funds, bringing the total investment to over $72 million for the coal facility improvements.

The funding announcement comes as Person County residents are already grappling with significant energy infrastructure changes in their community. The area is simultaneously dealing with the construction of new natural gas power plants, pipeline development, and a proposed Microsoft data center that would dramatically increase local energy demand.

The Roxboro plant upgrades are part of a broader national initiative, with similar coal plant improvement projects planned across 13 locations nationwide. This federal investment in coal infrastructure represents a notable shift toward supporting fossil fuel facilities at a time when many utilities are transitioning away from coal-fired power generation due to environmental concerns and economic factors.

The timing of these coal plant upgrades has raised questions among environmental advocates about the long-term energy strategy for the region, particularly given the concurrent natural gas development and the growing energy needs from technology companies establishing data centers in North Carolina. The combination of these projects signals a continued reliance on fossil fuel infrastructure despite ongoing climate commitments at state and federal levels.

The federal government is preparing to step in with its own 10-year management framework for the Colorado River if the seven states that depend on this critical water source cannot reach an agreement by summer’s end. Scott Cameron, acting commissioner for the Bureau of Reclamation, announced the ultimatum at a water conference in Boulder, Colorado.

The Colorado River Basin is experiencing its worst water year on record, intensifying pressure on negotiations that have been deadlocked for months. The river supplies water to approximately 40 million people across Arizona, California, Colorado, Nevada, New Mexico, Utah, and Wyoming, making any management decision crucial for the region’s future.

Years of severe drought, combined with rising temperatures and increased water demand, have pushed the river system to critical levels. Major reservoirs like Lake Mead and Lake Powell have dropped to historic lows, forcing difficult conversations about water allocation among the basin states. Despite the urgency of the situation, the states have struggled to agree on how to share reduced water supplies and implement necessary conservation measures.

If federal intervention becomes necessary, it would mark a significant shift in how the Colorado River is managed. The Bureau of Reclamation’s imposed framework would override state-level negotiations and establish binding water use guidelines for the next decade, potentially reshaping water rights and usage patterns across the entire Southwest.

The U.S. Department of Energy announced a massive $700 million funding package on Thursday aimed at bolstering the nation’s declining coal industry, drawing sharp criticism from environmental advocates who argue the move prioritizes outdated energy sources over cleaner alternatives.

The funding, sourced from the Defense Production Act, includes $425 million specifically designated to extend the operational lifespan of 12 coal-fired power plants across multiple states. Among the recipients, the Wheeling Power Company will receive $50 million to “modernize” its Mitchell Plant facility in Moundsville, West Virginia. The remaining $275 million will reportedly fund the construction of two new coal plants, as part of what officials are calling an “energy dominance” strategy.

Environmental groups have condemned the announcement, emphasizing that coal remains one of the most polluting and increasingly expensive forms of energy generation. Critics argue that the substantial federal investment contradicts national climate commitments and represents a step backward in the transition toward renewable energy sources. They point to coal’s significant contribution to greenhouse gas emissions and air pollution, which pose serious risks to public health and environmental quality.

The funding comes at a time when the coal industry has been struggling economically, with many plants closing due to competition from cheaper natural gas and renewable energy sources. While supporters argue the investment will preserve jobs and maintain energy security, opponents question whether taxpayer dollars should support an industry that many consider obsolete in the face of climate change.

What would you grab if you had just minutes to evacuate your home before a wildfire or hurricane struck? Your family photos? A beloved pet? That handmade quilt from your grandmother?

This deeply personal question lies at the heart of the Museum of Unnatural Disasters, a powerful new pop-up exhibit that has opened in Washington DC. The interactive display forces visitors to confront the human reality behind climate change statistics by focusing on the impossible choices people face when extreme weather threatens everything they hold dear.

The museum brings together an unlikely coalition of voices – disaster survivors sharing their harrowing experiences, lawmakers grappling with policy responses, and activists demanding urgent action. Through personal stories and immersive displays, visitors experience what it means to lose a lifetime of memories to rising floodwaters or watch irreplaceable family heirlooms turn to ash in a wildfire.

The exhibit arrives at a critical moment as extreme weather events become increasingly frequent and severe across the United States. By transforming abstract climate data into visceral, emotional experiences, the museum aims to bridge the gap between scientific warnings and public understanding. Rather than overwhelming visitors with statistics about global temperature rise, the display asks them to imagine their own most treasured possessions at risk, making the climate crisis intensely personal and immediate.

Montana is preparing for what could be one of its most challenging wildfire seasons in recent years, as a dangerous combination of environmental factors creates elevated fire risk across the state. Officials warned this week that drought conditions, unusual wind patterns, and warmer-than-average winter temperatures are setting the stage for above-normal wildfire activity in 2026.

The concerning forecast comes as the state grapples with ongoing climate challenges that have made wildfire seasons increasingly unpredictable and severe. Warmer winter temperatures have reduced snowpack levels, while persistent drought conditions have left vegetation dry and highly combustible. When combined with expected wind events throughout the fire season, these factors create ideal conditions for rapid fire spread and intensity.

Adding to the challenges, Montana’s firefighting infrastructure faces significant strain. Volunteer fire departments, which often serve as the crucial first responders to emerging blazes, are struggling with recruitment and staffing shortages. Meanwhile, federal firefighting agencies are undergoing organizational changes that could impact response capabilities during critical moments.

The early warning allows communities across Montana to begin preparation efforts, including vegetation management, emergency planning, and resource allocation. State officials emphasized the importance of proactive measures, as the convergence of drought, heat, and wind creates conditions where small fires can rapidly escalate into major emergencies that threaten both natural landscapes and human communities.

When the third known object from the galactic space beyond our Sun barreled through the solar system last year, Earth was in a terrible spot to view its flyby. Thankfully, however, a spacecraft that was previously busy mapping Mars took advantage of much better positioning for a closer look.

Cheap Seats

Astronomers have now observed three interstellar objects as they’ve flown through the solar system: 1I/ʻOumuamua, which shocked astronomers in 2017; 2I/Borisov, which followed in 2019 and behaved almost identically to a solar system comet; and now 3I/ATLAS, which was found buzzing toward the Sun in July 2025. As soon as 3I/ATLAS was spotted, pretty much every telescope on the planet took a look. The data swiftly revealed much that intrigued astronomers: while 3I/ATLAS was behaving essentially like a standard comet, its chemistry was nothing like its solar system counterparts, and its coma and dust outflow were strangely shaped. Among other oddities, it seemed to counterintuitively have a dust tail that pointed toward the Sun.

Better View from Mars

The Tianwen-1 spacecraft, which entered Martian orbit in early 2021 and has been diligently mapping the Red Planet ever since, has a high-resolution camera that’s normally pointed at the planet’s surface. By spinning the spacecraft around, a team of researchers led by Xin Ren (National Astronomical Observatories, Chinese Academy of Sciences) repurposed the camera to act as a small telescope when 3I/ATLAS flew by. In another cosmic coincidence, 3I/ATLAS happened to pass very near Mars last fall, and this close approach gave Tianwen-1 a great out-of-plane view of the coma. The orbiter managed to capture 57 images of 3I/ATLAS over three days last fall, representing China’s first-ever observations of an object from an asset in deep space.

As new surveys begin to turn up interstellar interlopers more often, this improvised observation makes a tidy point: the spacecraft already scattered across the solar system can double as a fleet of opportunistic comet-watchers, each offering a view we simply can’t get from home.

Planets that get too close to their host stars are liable to be engulfed and consumed. New research explores how to identify stars that have had a planetary snack.

It’s Snack Time

Being a planet that closely orbits its star is dangerous, and various dynamical processes can draw a planet inward past the point of no return. When a planet vanishes beneath the surface of its host, it eventually disintegrates within the star, its atoms mixing into the blazing stellar soup.

This outcome is likely extremely common across the universe, and researchers have begun to see evidence for it: stars that appear to have absorbed angular momentum from their planets, white dwarfs with uncanny metals in their spectra, and stars with chemical abundances that don’t match those of their siblings. Now, in a recent publication led by Kaitlyn Lane (Vanderbilt University), researchers seek to find observational signatures of planetary engulfment of rocky exoplanets by main-sequence stars.

Modeling Engulfment

Lane’s team focused on main-sequence stars in the range of 0.5 to 1.4 solar masses, using one-dimensional analytical models to determine which of these stars will most readily display signs of having engulfed a planet. They simulated the stars as they consumed either an Earth-like planet or a super-Earth with the same composition as Earth but 15 times its mass.

After that relatively lengthy phase, the process proceeds rapidly: as the planet inches deeper into its star, the drag forces grow stronger and the planet’s demise accelerates, with the planet disintegrating over the course of hours. In the last phase, the planet makes its final plunge and is destroyed in a half hour.

Signs of Planets Past

Lane’s team found that the planets tended to be destroyed fully within the outer convective layer of their stars, except in the case of the most massive stars studied here. For more massive stars, the outer convective zone is shallower than it is for the less massive stars, allowing a chunk of each planet to survive the passage through the convective zone to reach the radiative zone below.

In the 1.4-solar-mass case, part of the planet survives to reach the radiative zone, but the shallowness of the star’s convective zone means that the disintegrated planetary material is easier to observe.

While the authors acknowledge that there’s more work to be done — they plan to investigate the impacts of planetary engulfment on stellar structure more closely, for example — this work represents an important foray into identifying targets for future studies of stars that have eaten their planets.
