Killer Whales Lingering in Newly Melted Arctic Ocean, Despite Risks of Ice Entrapment
Melting ice opens new predation ground for killer whales as they spend more time in previously neglected territory. Killer whales are intelligent, adaptive predators, often…
Rainfall in Arctic Will Soon Be More Common Than Snowfall – Decades Earlier Than Thought
Changes will happen decades earlier than previously thought. More rain than snow will fall in the Arctic and this transition will occur decades earlier than…
Rhythms of the Krill: Exploring Response to Visual Changes During Arctic Night
New research explores animals’ visual rhythms during the Arctic polar night. Around 11:30 a.m. or so, you might find yourself hankering for lunch. The reason…
Flawed Climate Models? Arctic Ocean Started Getting Warmer Decades Earlier Than We Thought
The Arctic Ocean has been getting warmer since the beginning of the 20th century – decades earlier than records suggest – due to warmer water…
Ancient Driftwood Tracks 500 Years of Arctic Warming, Currents, and Sea Ice
Fallen trees kept afloat in sea ice reflect accelerated ice loss in the last 30 years. A new study reconstructs the path of frozen trees…
New DNA Research Shows Humans Did Not Cause Woolly Mammoths To Go Extinct – Climate Change Did
New DNA research shows the world got too wet for the giant animals to survive. For five million years, woolly mammoths roamed the earth until…
New Understanding of the Arctic’s Carbon Cycle – How Carbon Is Transferred Between Land, Ocean, and Atmosphere
New research from UMass Amherst shines light on poorly understood processes of how carbon dissolved in Arctic rivers affects our world. In a pair of…
