Kristen Villebrun and Wendy Bush hoped they wouldn't have to pray for Chedoke Creek, but four years after they first raised alarm about the water's condition, they were part of an Indigenous full moon ceremony to do just that. About 50 people showed up near Princess Point on the dark and frigid Monday evening for the monthly ceremony, which was particularly special as it focused on Chedoke Creek. The body of water that runs into Cootes Paradise had about 24 billion litres of sewage and storm water runoff leak into it due to a gate being left open.

Harmful algal blooms work by disrupting food webs, Dr Caron said. Creatures such as shellfish, anchovies and sardines consume the toxins before then being eaten by larger marine mammals. "They eat a meal of those highly toxic fish and then they become toxified themselves, and if they get enough of that material, it of course can kill them, which is happening now," he said.
What’s behind this rapid increase isn’t totally clear yet. “These temperatures just rocketed up, people haven’t had a chance to puzzle it all out,” Johnson said. Some scientists are concerned the scale of these new records could mark the start of an alarming trend. Others say record-breaking temperatures like these are always concerning but to be expected given the human-caused climate crisis. All agree the consequences are likely to be significant. Warmer oceans bleach coral, kill marine life, increase sea level rise and make the ocean less efficient at absorbing planet-warming pollution – the warmer oceans get, the more the planet will heat.
Last summer, scientists at the National Oceanic and Atmospheric Administration observed dust blowing 85 miles from its source: Lake Abert and Summer Lake, two dried-up saline lakes in southern Oregon. This has happened before: Saline lakebeds are some of the West’s most significant sources of dust. California's Owens Lake is the nation's largest source of PM10, the tiny pollutants found in dust and smoke, while plumes blowing off the 800 square miles of the Great Salt Lake’s exposed bed have caused toxin-filled dust storms in Salt Lake City.
Some parts of the Arctic don't look very polar anymore. Many regions are likely transforming from snowfall- to rainfall-dominant climates, according to the National Oceanic and Atmospheric Administration. "At the fringes, the transition is essentially occurring already," John Walsh, chief scientist at the International Arctic Research Center at the University of Alaska Fairbanks, said in a briefing at the fall meeting of the American Geophysical Union on Tuesday.
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.
Clean-up crews and the US Coast Guard are trying to locate the source of an oil spill spotted in the Gulf of Mexico after deadly Hurricane Ida. Recent satellite photos by the National Oceanic and Atmospheric Administration (NOAA) showed the slick about two miles (3km) off Port Fourchon, Louisiana. It appears to be coming from a source underwater at an offshore drilling site, the Associated Press reports.
As the climate continues to warm at an alarming rate, experts warn if dramatic steps to mitigate global warming are not taken, the effects in Canada’s Prairie region will be devastating to the country’s agriculture sector. According to Environment and Climate Change Canada, the country is warming, on average, about double the global rate. Scientists with the National Oceanic and Atmospheric Administration in the U.S. recently found 2020 was earth’s second-hottest year on record, with the average land and ocean surface temperature across the globe at 0.98 of a degree C above the 20th-century average. However, the agency found the northern hemisphere saw its hottest year on record, at 1.28 degrees C above the average.
