McGill-led research unravels mystery of how early animals survived ice age
New findings further our understanding of extreme climate change and evolution
Evidence: Antarctica’s thinning ice shelves causing more ice to move from land into sea

Drone images show Greenland ice sheet becoming more unstable as it fractures
The world’s second-largest ice sheet, and the single largest contributor to global sea-level rise, is potentially becoming unstable because of fractures developing in response to faster ice flow and more meltwater forming on its surface. Using custom-built drones strong enough…

Species can’t adapt to rapid environmental changes
Marine community composition shifts in predictable ways in warming oceans
Global simulations suggest plankton and fish species are showing resilience to climate change by going deeper underwater or moving to higher latitudes. Anticipating changes in community composition in response to warming is challenging because species respond differently and the interactions…
Changes in oxygen concentrations in our ocean can disrupt fundamental biological cycles
New research led by scientists at the University of Bristol has shown that the feedback mechanisms that were thought to keep the marine nitrogen cycle relatively stable over geological time can break down when oxygen levels in the ocean decline…
Meeting the challenges facing fisheries climate risk insurance
Insurance schemes with the potential to improve the resilience of global fisheries face a host of future challenges, researchers say. The world’s first “Fisheries Index Insurance” scheme, launched by an international consortium in July, is a sovereign-level instrument designed to…

El Nino swings more violently in the industrial age, compelling hard evidence says
El Ninos have become more intense in the industrial age, which stands to worsen storms, drought, and coral bleaching in El Nino years. A new study has found compelling evidence in the Pacific Ocean that the stronger El Ninos are…
Life under extreme conditions at hot springs in the ocean
The volcanic island of Kueishantao in northeastern Taiwan is an extreme habitat for marine organisms. With an active volcano, the coastal area has a unique hydrothermal field with a multitude of hot springs and volcanic gases. The acidity of the…
