Sea ice thickness is inferred by […]

New research by LLNL scientists shows that satellite measurements of the temperature of the troposphere (the lowest region of the atmosphere) may have underestimated global warming over the last 40 years. One of the physical processes they looked at was tropical water vapor like shown in this NASA image. Credit: […]

This was taken in the Scotia Sea during the coring campaign in 2007. Credit: Michael Weber New calculations show the rise due to warming would be 30% above forecasts. Global sea level rise associated with the possible collapse of the West Antarctic Ice Sheet has been significantly underestimated in previous […]

Destruction of the Larsen B platform in Antarctica, images from January 31 to April 13, 2002. Credit: NASA   ANIMATION Fractures from melting and run-off will indirectly lead to sea level rise. More than a third of the Antarctic’s ice shelf area could be at risk of collapsing into the sea […]

Using sea charts and satellites, the effort will trace how the kelp beds are changing in response to global warming and commercial harvesting. PHOTOGRAPH: GETTY IMAGES THIS STORY ORIGINALLY appeared in Canada’s National Observer and is part of the Climate Desk collaboration. An ambitious project to map and monitor sea kelp forests along the entire […]

Oxygen levels in the ancient oceans were surprisingly resilient to climate change, new research suggests. Scientists used geological samples to estimate ocean oxygen during a period of global warming 56 million years ago — and found “limited expansion” of seafloor anoxia (absence of oxygen). Global warming — both past and […]

Fishing boats amidst “Arctic sea smoke” near Qingdao, China on January 7th. Arctic sea smoke is a result of frigid air passing over relatively warm water; the phenomenon is rare, even in the Arctic.

ANIMATION For animals in the Arctic, life is a balancing act. Seasonal cues, such as warmer spring temperatures or cooler temperatures in the fall, tell animals when to migrate, when to mate, and when and where to find food. Predators and prey, birds and mammals alike follow this natural schedule, […]
