The Lut Desert in Iran is an exceptional natural laboratory to study how wind moves sediment across the landscape. A new study quantifies erosional and depositional sediment fluxes of the desert.
In a happy accident, scientists found a potential solution to an atmospheric chemistry mystery. Their findings could be a missing piece in the iodine cycle and in atmospheric models.
A new study reveals the atmospheric paths of storm events that can deliver a decade’s worth of rain in a few hours to the Atacama Desert.
In experiments conducted in Biosphere 2, invasive buffelgrass weathers higher temperatures and drought conditions better than its native brethren.
Bacteria can speed up the growth of biocrust-forming organisms in nurseries, providing more material for restoration of degraded dryland soil.
Dunes may morph or creep in new directions in a warming world.
Hand axes, hippo bones, and a stack of ancient lake beds show that arid Arabia experienced intervals of humid weather, spurring pulses of human migration over the past 400,000 years.
Without water, photosynthesis shuts down. To survive dry spells, desert microbes scavenge traces of hydrogen from the air and burn it for energy. Some even use hydrogen to fuel carbon fixation.
A fence spans Australia’s Strzelecki Desert, keeping dingoes out of the southern side. Drone and satellite technology have illustrated how removing this top predator changes vegetation growth.
Indigenous Peoples from the Arctic and the U.S. Southwest have joined together to tackle issues of food sovereignty in two environmental extremes. Their bond led to a swift response to COVID-19.
