The piece argues that dust storms—historically deadly 'Dust Bowl' events—are returning to the US as hotter, drier conditions and waning vegetation lift dust into the sky, with health risks ranging from dust pneumonia to Valley Fever; it cites 2025 events in El Paso and New Mexico and warns that climate change could make such 'deathstorms' more frequent and costly unless mitigation and forecasting improve.
Dust storms, heavy rain and lightning across several districts in Uttar Pradesh killed at least 96 people and injured more than 50, with fatalities from collapsing walls and fallen trees; emergency teams cleared debris, authorities pledged relief and compensation, and Chief Minister Yogi Adityanath ordered rapid relief operations focused on Prayagraj and surrounding areas.
A localized Martian Year 37 dust storm lifted water vapor into the middle atmosphere at levels up to ten times typical, with hydrogen at the exobase rising about 2.5×. This suggests small, regional storms contribute to Mars’s long-term water loss and challenges the idea that southern-summer global events were the main driver, using data from ExoMars TGO, MRO, and the Emirates Mars Mission.
A computational study shows Venus’ winds help moderate its extreme day–night temperatures, with highland regions staying nearly constant while lowlands swing by several kelvin; the research also notes frequent dust storms that could affect landers, arguing for a regional approach to mission planning and landing-site selection (e.g., DaVINCI and EnVision).
NASA’s MAVEN orbiter has captured the first confirmed electrical signal consistent with lightning in Mars’ atmosphere—a low-frequency ‘lightning whistler’ likely produced inside dust storms. The discovery confirms Martian atmospheric electricity, though the discharges are weaker than Earth’s, and researchers will continue searching for clusters to map where such events occur and how they influence Martian chemistry.
Two NASA missions—MAVEN in orbit and the Perseverance rover on the surface—have detected signals suggesting lightning or related electrical discharges in Mars' dusty atmosphere. MAVEN identified a rare whistler radio signal from a 2015 data set, while Perseverance recorded crackling sounds during dust storms likely from electrostatic discharges in charged dust clouds. Taken together, the findings strengthen the case that Mars experiences dust-driven electrical activity, with possible implications for atmospheric chemistry and the planet's environment, though large lightning bolts remain unlikely.
A new study shows that small, regional dust storms on Mars can lift water vapor to higher altitudes and boost hydrogen escape, significantly contributing to the planet's long-term water loss and prompting updates to climate models.
A new study argues that Martian dust storms generate electrostatic discharges that create high-energy electrons, driving reactions between atmospheric CO2 and ground chloride salts to form perchlorates and carbonates without liquid water. This electrochemical pathway also explains the observed isotopic imbalances, with lighter isotopes preferentially involved in these reactions. The research, demonstrated in lab chambers simulating Mars’ environment, suggests electrical processes are a key driver of Mars’ surface chemistry, poses ongoing challenges for future missions (due to perchlorates), and may have parallels on other dusty worlds.
China and Mongolia are engaged in efforts to combat dust storms and desertification, with China sharing its expertise and Mongolia hosting a UN conference on the issue, amid concerns over environmental degradation, climate change, and territorial sensitivities.
Scientists have detected tiny lightning bolts on Mars for the first time, occurring around dust storms and dust devils, which helps explain the presence of oxidants like hydrogen peroxide on the planet and opens new avenues for understanding Martian weather and potential habitability.
New research reveals that dust storms around the Great Salt Lake are more frequent than previously thought, posing health risks especially to children due to toxic metals like arsenic and lead. The study highlights the need for better monitoring and preventative measures to protect communities from airborne pollutants originating from the lake's receding shoreline and industrial activities.
Burning Man attendees in Nevada's Black Rock Desert face severe weather, including dust storms, high winds, heat, humidity, and potential flooding, causing delays, injuries, and challenging conditions at the festival.
Researchers have found that 78% of dust storms on Mars are preceded by increased solar heating, suggesting a potential method for forecasting these storms. Dust storms pose significant challenges for Mars missions, affecting rovers and future crewed missions by covering solar panels with dust. The study, using data from NASA's Mars Reconnaissance Orbiter, highlights the correlation between warmer days and dust storm activity, although the exact physics of storm formation remains unclear. This research could aid in predicting and preparing for dust storms on Mars.
A team of scientists from the University of Colorado Boulder has identified weather patterns that may trigger major dust storms on Mars, which could pose risks to future human missions. Using data from NASA's Reconnaissance Orbiter, they found that around 68% of these storms are preceded by a rise in surface temperatures due to warm and sunny weather. Understanding these patterns is crucial for predicting and mitigating the impact of dust storms on Mars, especially as NASA plans to land astronauts on the planet by 2030.
Increasing winds are causing dust storms at the Burning Man encampment in Black Rock City, Nevada, with conditions expected to worsen on Friday. The National Weather Service has issued warnings for gusts up to 40 mph, which can cause problems for outdoor activities and result in blowing dust. Showers and possibly a thunderstorm are forecasted for Friday, along with cooler temperatures. The wet conditions have already delayed the construction of art installations and camp structures. Burning Man runs through Monday, with planned burns depending on the weather.
