Landfast sea ice, sea ice that is held stationary against the Antarctic continent, links firmly with many key climate processes, but its importance is only being fully realized as its extent dwindles.
Nutrients from the seabirds’ guano fuels the growth of carbon-storing phytoplankton, but penguin populations have plunged in the past 4 decades.
Antarctica’s Thwaites and Pine Island Glaciers are melting faster than they have in the past 5,500 years, new evidence shows. Against expectations, their pasts have been remarkably stable.
Tools developed for climate science can help researchers forecast ecological dipoles: the contrasting effects of climate on populations separated by thousands of kilometers.
Scientists are digging up Adélie penguin guano to study millennia of Antarctica’s history.
How quickly the penguins huddled when weather worsened provided clues about their feeding success and how climate change may alter the Antarctic biosphere, according to scientists.
The Galápagos cold pool is expanding northward as a result of climate change, and local penguin populations are rising.
New research that may presage effects of climate change on this species looks back 22,000 years, finding robust growth in the East Antarctic population as melting followed the last ice age.
