Hundreds are set to descend on Tahiti for Olympic surfing. Can locals protect their way of life?

"...TEAHUPO'O, French Polynesia (AP) Peva Levy said he felt a powerful, natural energy known as mana when he surfed Teahupo'os waves on a piece of plywood for the first time, rushing down a crumbling white surf in front of an untouched volcanic beach several years before the steady streams of surfers started arriving when the village got its first asphalt road over fifty years ago..."

Pipe leaking sewage into Red River not fixed yet, Winnipeg Councillor says

"...Despite the dilution, the presence of so much sewage in the river will increase levels of nitrogen and phosphorous in the river, leading to more green algae in Lake Winnipeg. In a statement Friday afternoon, the Chiefs of Treaty One Nations expressed alarm at the environmental impact of the leak, and called for a proactive response from the city, rather than its current reactive course of bypassing the pipe. Our First Nations rely on our waters for sustenance, yet our lands and waters are increasingly encroached upon, hindering our ability to practice traditional livelihoods,” Chief Gordon BlueSky of Brokenhead Ojibway Nation — the Treaty One Nations chair — said..."

Can Animals Evolve Fast Enough to Keep Up with Climate Change? Hakai Magazine

"...In a new comprehensive review, Diamond and her colleagues pulled together existing research on how quickly species can evolve climate-relevant traits, such as the ability to withstand high temperatures, dry conditions, or ocean acidification. Their sweep of the literature revealed plenty of good news. One of the laboratory experiments they looked at, for example, showed that one species of green algae, Chlorella vulgaris, can rapidly evolve to tolerate temperatures 3 oC higher than its usual optimum..."

Climate change is further reducing fish stocks with worrisome implications for global food supplies

"...Threats to seafood access arent just due to overharvesting. There is a growing body of research showing that higher water temperatures due to climate change can impact the presence and abundance of the catch, through shifts in species distribution and changes in the species caught. This impacts the amount that can be harvested, as well as the nutritional value of that harvest..."

Zebra mussels found in Clear Lake, Man., raising concerns about spread of invasive species

"...Now that they're in Clear Lake, there is concern for lakes both inside and outside Riding Mountain park. “As far as we know, Clear Lake is now the most western lake in Canada to be invaded with zebra mussels, and we don't want them to spread westward,” Higgins said, adding it's even more important now that Parks Canada continue its stringent boating protocols to contain the spread. He said water bodies with higher calcium make it harder for the mussels to thrive..."

Kelp Keeps a Record of Environmental Calamity Hakai Magazine

"...On November 14, 2016, a huge earthquake rocked Kaikura, a town on New Zealand's South Island, killing two people, triggering a tsunami, and thrusting stretches of coastline six meters up out of the sea. Biologists Ceridwen Fraser and Jon Waters were watching the aftermath on television. We were seeing images of kelp and [abalone] lifted out of the water and dying, says Waters..."

Team effort needed to tackle Manitoba lake pollution, experts say

"...More and more blue-green sludge has washed up on the banks of Lake Winnipeg in recent years, threatening the health of both the lakes aquatic species population and the water supply. Lake Winnipegs watershed spans one million square kilometres with various sources polluting it, including contaminants from the Red River, the Saskatchewan River, the Dauphin River, municipal wastewater treatment plants, urban lawns and gardens, and agricultural runoff. Inoka Amarakoon, assistant professor in the department of soil science at the University of Manitoba, said better nutrient management is the only way to control and prevent increased blooms..."
