Nova Scotia releases public education campaign on blue-green algae

Water Canada

A new public education campaign will help Nova Scotians become more aware of blue-green algae when enjoying the province’s outdoors with the arrival of warmer weather. Cyanobacteria, or blue-green algae, are naturally occurring in freshwaters like lakes, ponds, rivers, and streams. They can flourish in water high in nutrients, especially during hot, dry conditions. The bacteria can be harmful to people and fatal for animals, so it is important that Nova Scotians know what to look for and how to protect themselves, their families, and pets.

Compare and Contrast: Pharmacy in the sea: Dolphins ‘use coral as medicine for skin ailments’

The Guardian

Who doesn’t like a bath scrub? Dolphins definitely do: they are known for being clever, playful, tactile animals, and they like to rub against rough surfaces, nap in coral beds and soak on sponges like guests at an underwater spa. However, dolphins may be getting more from their bath scrubs than just relaxation and leisure. A study published today suggests that bottlenose dolphins may be self-medicating their skin ailments with the help of corals, adding to growing research on their previously unexplored medicinal properties.

How Atlantic Canada’s warming ocean could impact everything from seaweed to lobster

CBC News

An Atlantic Canadian biotechnology seafood company says it’s seeing the effects of warming ocean temperatures as levels of the cold-water seaweed it harvests have plunged in one area. Acadian Seaplants converts the seaweed Ascophyllum nodosum into ingredients used in many food, household and fertilizer products. But the southern range of Ascophyllum in Massachusetts is now far less productive than it used to be, according to Acadian Seaplants CEO J.P. Deveau. Click here to continue reading

Flood fight ramps up in Minnedosa amid heavy rainfall

CBC News

The flood fight continues in parts of western Manitoba. And with a rainfall warning in place due to a weather system expected to bring 30 to 40 millimetres by Friday morning, people in the southwestern town of Minnedosa were frantically sandbagging and pumping water throughout a downpour Thursday, as the Little Saskatchewan River inched higher. Right now, volunteers are using sandbags to reinforce dikes on the north and south sides of the river to hold the water back from nearby homes and businesses. Click here to continue reading

For wetland plants, sea level rise stamps out benefits of higher CO2

Water Canada

Wetlands across the globe are in danger of drowning from rising seas. But for decades, scientists held out hope that another aspect of climate change — rising carbon dioxide (CO2) — could trigger extra plant growth, enabling coastal wetlands to grow fast enough to outpace sea-level rise. That helpful side effect is disappearing, they discovered in a new study. Conserving wetlands is critical both to fight climate change and adapt to it. Besides providing habitat, wetlands sequester massive amounts of carbon and protect people from some of climate change’s more extreme effects, such as hurricanes and typhoons.

Co-Operators renews commitment to building flood resilience

Water Canada

Co-operators has renewed its multi-year funding commitment to Partners for Action (P4A), a research initiative at the University of Waterloo that focuses on empowering Canadians to become flood resilient, with a three-year commitment of $500,000 towards program delivery and research. The increasing frequency and severity of extreme weather and its devastating impacts are top of mind for Canadians after the severe flooding in British Columbia late in 2021, and more recently the flooding in Manitoba.

Community to meet to discuss proposed feedlot near fragile Alberta recreational lake

CTV News

Cottage owners and farmers who say a proposed feedlot threatens the water quality of a popular lake are to gather this weekend to discuss how they can keep making their case to the regulatory body that will rule on the project. Pigeon Lake is unusual in that it’s fed by runoff, not streams or rivers, and is drained by a single creek. That makes the lake highly vulnerable to algal blooms fed by nutrients washing into its waters. Click here to continue reading

Compare and Contrast: The Lasting Agreement – California’s long legacy of trying to solve its water problem

Comstock’s Magazine

If there’s one thing people in the West know how to fight over, it’s water. California was built on scarcity, whether it be gold or silver, land or water. In the mid-1800s, when European Americans arrived to the land where Indigenous people had lived for at least 10,000 years, they wasted no time staking their claims. A big head-scratcher for those early colonizers was how to get water to sustain burgeoning towns. California’s hydrology didn’t match where people wanted to live. Click here to continue reading

Compare and Contrast: Climate change will force big shift in timing, amount of snowmelt across Colorado River Basin

Science Daily

New research predicts that changes in mountain snowmelt will shift peak streamflows to much earlier in the year for the vast Colorado River Basin, altering reservoir management and irrigation across the entire region. The basin stretches from sea level at the Gulf of California to higher than 14,000 feet in the Rocky Mountains of Colorado and provides critical water to cities and farmers within the basin and beyond. Significant water is diverted to large population centers, including Albuquerque, Denver, Los Angeles, Salt Lake City, San Diego and Santa Fe. Click here to continue reading

York research team removes harmful waste from Canada’s groundwater

Water Canada

An internationally recognized leader in the development of novel green technologies, Professor Satinder Kaur Brar, Lassonde School of Engineering, is on a mission to add value to residues and remove toxic compounds from the environment that pose extreme hazards to ecological and human health. Brar’s research hinges on two main themes: the removal of emerging contaminants such as plastics, chemical antibiotics, and pesticides from wastewater and drinking supply water; and value-addition of wastes.
