As climate change reshapes Arctic food webs, ringed seals will swim into risky polar bear territory if the menu is varied enough.
That’s the central finding of a new study published in Ecology Letters. UBC researchers tracked 26 ringed seals and 39 polar bears in eastern Hudson Bay, using GPS and dive information to analyze how the animals found, and avoided becoming, food.
New analyses of ancient ice from Antarctica and the air contained inside it are extending the history of Earth’s climate records and expanding researchers’ understanding of how the planet has changed over the last 3 million years.
Sea ice around Antarctica expanded for several decades until a dramatic decline in 2015. The reasons behind this are revealed by research from the University of Gothenburg.
New Stanford-led research traces a direct line from warmer, wetter weather to a mosquito-borne disease epidemic. The findings could help inform policy and interventions to blunt such outbreaks.
Commercial whaling has left the bowhead whale vulnerable for many generations to come.
Small changes to aircraft flight paths to avoid the atmospheric conditions that create condensation trails – known as contrails – could reduce aviation’s global warming impact by nearly half, a new study suggests.
