Hurricane Fiona is the most devastating storm to hit Atlantic Canada. International collaboration between ocean measurement institutions is necessary to help efficiently plan responses to hurricanes.
Hurricanes don’t usually maintain high wind speeds as they make their way toward Atlantic Canada. But ocean warming may be linked to the increasing intensity of storms like Fiona.
As the ocean temperature rises, many marine species are moving toward the north and south poles in search of cooler waters, thus rewriting the menus of seafood restaurants on the West Coast of Canada.
Tiny seashells draw carbon to the ocean floor when they die. This is the most significant geological process of carbon storage today, and it might increase in a warmer world, as it did in the past.
Sponges are ancient marine animals and have already shown robustness against stresses from climate change. New research now shows they can also tolerate low-oxygen conditions.
The ocean has been buffering us from the impacts of climate change, but it is reaching the limit of this capacity. Integrating ocean and climate policy will be crucial.

How scientists are improving their understanding of the connection between extremes and climate change – and what’s to come. Listen to The Conversation Weekly.
A new analysis, using 15 years of autonomous underwater measurements and simulations from the latest global climate models, refined our estimate of future ocean warming and sea level rise.
Corals in the Persian Gulf are tough - they can withstand temperatures that would kill corals elsewhere. And there’s good news: it’s easy to cross-breed their heat-tolerance genes into other corals.
Australia may warm by 4°C or more this century, the IPCC has found. As these IPCC authors explain, there is no going back from some changes in the climate system.

The triple whammy of the moon’s wobble, sea level rise and more intense storms will bring worse tidal floods into coastal communities in the 2030s. This includes in Australia.
A study of 183 coral reefs worldwide quantified the impacts of ocean warming and acidification on reef growth rates. Even under the lowest emissions scenarios, the future of reefs is not bright.
The Southern (Antarctic) Ocean is our planet’s primary storage of heat and carbon, and it’s home to extraordinary life forms, from tiny algae and spineless creatures to penguins, seals and whales.
