The rapid melting of Antarctic ice poses a threat to halt deep ocean currents, which would have a negative impact on the climate, the movement of fresh water and oxygen, as well as nutrients necessary for life, for centuries, as per claims from the scientific community, reported by DW. Deep ocean currents surrounding Antarctica may slow by more than 40% over the course of the next 30 years, according to a recent study that was published in the journal Nature on Wednesday. According to the study, in a high-emission scenario, the "overturning circulation" of the ocean's deep waters will reduce by 40% by 2050, with consequences lasting "for generations to come."
Coastal communities in Quebec's Gaspé Peninsula fight ravaging seas, climate change by retreating Social Sharing
Against the ravaging seas, Quebec's coastal communities have learned through bitter experience that the way to advance against climate change is to retreat. Over the past decade, civilization has been pulled back from the water's edge where possible along the eastern stretch of the Gaspé Peninsula where coastline is particularly vulnerable to erosion. Defences erected against the sea ages ago have been dismantled, rock by rock, concrete chunk by chunk.
Empowering B.C. communities to protect their local watersheds
The extreme climate impacts experienced in B.C. in 2021 are ushering in new mainstream vocabulary as more and more people grapple with the enormity of the consequences taking place. Heat domes. Atmospheric rivers. Ecosystem resilience. Watershed security. Climate anxiety. All recent additions to our everyday lexicon. Climate change has swiftly become the climate crisis, as the catastrophic flooding and landslides in recent weeks have shown, preceded by the record heat waves, drought and fires of the summer.
‘Mayhem’: Severe wildfires could threaten water supply for communities, expert warns
There is more to learn about the consequences of intensifying wildfires on community watersheds across Canada, but a large, severe fire followed by heavy precipitation could seriously affect drinking water, says a wildfire research scientist with the Canadian Forest Service. An intense fire can burn through vegetation and soil that serve to absorb and more evenly distribute precipitation or melting snow, and also naturally filter sediment and toxins before the water even reaches a community’s drinking-water source, Francois-Nicolas Robinne said in an interview from Edmonton.
First Nations workers in Sask. sacrifice wages, vacation to run underfunded water systems
Rebecca Zagozewski is the executive director of the Saskatchewan First Nations Water Association, a non-profit organization that works to build First Nations’ capacity to take care and control of their own water services. She says recruitment and retention of water treatment plant operators is a “real problem” on Saskatchewan First Nations, largely because they often can’t pay operators competitive wages.
