Global Water Loss Happens Almost Entirely in the Southern Hemisphere
A recent study suggests that the Southern Hemisphere not only is more vulnerable to climate change but also loses significantly more water than the Northern Hemisphere.
How Llama Poop Is Helping an Andean Community Adapt to Melting Glaciers
Reintroducing these animals can enrich barren soils and potentially reduce water contamination, a study shows.
A 150-Day Periodicity is Revealed in the Southern Extratropics
An internally generated 150-day periodicity is newly identified in the Southern Hemisphere extratropical large-scale atmospheric circulation, which arises from the annular mode’s propagating regime.
The Crust Travels to the Earth’s Core and Back in Record Time
Subduction of continental crust around the Gondwana supercontinent may explain the mantle Dupal anomaly of the southern hemisphere.
Diagnosing Neptune’s Chilly Summer
A pandemic project analyzing a trove of infrared images revealed an unexplained phenomenon taking place in Neptune’s atmosphere.
Current History: Exploring the Past of the Tasman Leakage
A new study sheds light on an important Pacific-to-Atlantic connecting current, including the global changes that led to its flowing that ushered in near-modern ocean circulation.
Is Earth’s Albedo Symmetric Between the Hemispheres?
The two hemispheres feature the same planetary albedo despite a larger land fraction in the north, because storms over the southern ocean are cloudier than their northern counterparts.
Southern Hemisphere Sediments Show Surprising Pliocene Cyclicity
New, high-resolution paleoclimate reconstructions with 100,000-year rhythms may offer insights into how Earth’s climate system operated during a time when the planet was warmer than it is today.
Estimating the Likelihood of Future Temperature Extremes
A prototype model allows scientists to investigate how wind eddies and other atmospheric phenomena may affect the prevalence of heat waves and cold snaps in the Southern Hemisphere.
