Our oceans are hotter than ever. Scientists say they worry about what that means for our future

Our oceans are hotter than ever. Scientists say they worry about what that means for our future

Amid another record warm year for the planet, one of the most dramatic and alarming changes occurred in our oceans, according to the National Oceanic and Atmospheric Administration (NOAA). They are the warmest they've been in recorded history. In fact, the ocean heat has been topping its own record annually for the past seven years, with last year's record set despite the absence of El Niño — a warming in part of the Pacific Ocean that tends to drive up global temperatures.

Government of Canada invests in research to study the effects of contaminants on aquatic ecosystems in Central Canada

Government of Canada invests in research to study the effects of contaminants on aquatic ecosystems in Central Canada

The Government of Canada is further investing in research to better inform the protection of our oceans, lakes, rivers and waterways and the many species that call them home. The unfortunate reality is that microplastics and pharmaceuticals enter our water systems due to human activity. This means we must continue to study and understand the threats that our ecosystems face.

Deep water temperatures hit 'scary' highs in Gulf of St. Lawrence

Deep water temperatures hit 'scary' highs in Gulf of St. Lawrence

A decade-long warming trend in the Gulf of St. Lawrence continued in 2020 with deep waters reaching record highs, according to ocean climate data released Tuesday by the Department of Fisheries and Oceans. Water temperatures at depths of 200, 250 and 300 metres were higher than any measured in the Gulf since records started in 1915, hitting highs of 5.7 C, 6.6 C and 6.8 C. All were well above the normal variations.

A TALE OF THREE WATERSHEDS: WHAT WE KNOW — AND DON’T KNOW — ABOUT THE HEALTH OF CANADA’S FRESHWATER

A TALE OF THREE WATERSHEDS: WHAT WE KNOW — AND DON’T KNOW — ABOUT THE HEALTH OF CANADA’S FRESHWATER

Canada is famously home to 20 percent of the world’s freshwater — but how well are we stewarding this supply? WWF-Canada recently reassessed the health of our country’s 25 watersheds to better understand how they’re responding to threats from pollution, habitat loss and climate change. Our 2020 Watershed Reports found that 26 per cent of Canadas’s 167 sub-watersheds received a score of Good or Very Good, which is good or very good news! But what’s bad, or possibly very bad, is that nearly 60 per cent of these sub-watersheds received no score at all because they remain Data Deficient. In other words, we just don’t know. This lack of data is concerning as we need a complete picture to determine which areas need dedicated efforts to protect our freshwater ecosystems.
