Rates of Chinook salmon bycatch in the Pacific hake fishery rise during years when ocean temperatures are warmer, a signal that climate change and increased frequency of marine heatwaves could lead to higher bycatch rates, new research indicates.

There has been much buzz about the warming planet’s melting Arctic region opening shipping routes and lengthening travel seasons in ocean passageways that ice once blocked. Expanded fishing, trade and tourism is envisioned.

Seabirds, from cormorants to puffins, spend most of their lives at sea.

An El Niño event has officially begun. The climate phenomenon, which originates in the tropical Pacific and occurs in intervals of a few years will shape weather across the planet for the next year or more and give rise to various climatic extremes.

Changes to the flow of the Labrador Current along the coast of Newfoundland and Labrador to Nova Scotia are leading to sudden warmings or drops in the oxygen levels of the waters in several regions including the St. Lawrence Gulf and Estuary.

By 2030, if the 30 by 30 initiative supported by more than 100 countries is successful, 30% of our land and ocean ecosystems will be designated protected areas meant to safeguard biodiversity and help limit the impacts of climate change.

Many of the world’s largest aquatic food producers are highly vulnerable to human-induced environmental change, with some of the highest-risk countries in Asia, Latin America and Africa demonstrating the lowest capacity for adaptation, a landmark study has shown.
