Climate change has been observed for hundreds of years by the plant specialists of three Odawa Tribes in the Upper Great Lakes along Lake Michigan. Sleeping Bear Dunes National Lakeshore is the focus of two National Park Service (NPS) studies of Odawa Traditional Ecological Knowledge (TEK) of plants, ecosystems, and climate change. Data collected during these studies contributed to developing Plant Gathering Agreements between tribes and parks. This analysis derived from 95 ethnographic interviews conducted by University of Arizona (UofA) anthropologists in partnership with tribal appointed representatives. Odawa people recognized in the park 288 plants and five habitats of traditional and contemporary concern. Tribal representatives explained that 115 of these traditional plants and all five habitats are known from multigenerational eyewitness accounts to have been impacted by climate change. The TEK study thus represents what Native people know about the environment. These research findings are neither intended to test their TEK nor the findings of Western science.
A loose raft of brown seaweed spanning about twice the width of the U.S. is inching across the Caribbean. Among annual Sargassum censuses in the Atlantic Ocean, “2018 was the record year, and we’ve had several big years since,” says Brian Lapointe, an oceanographer at Florida Atlantic University, who has studied seaweed for decades. “This is the new normal, and we’re going to have to adapt to it.”
A study published in Nature Climate Change examined how 10 big rivers in the Arctic had moved 50 years, and found they did not migrate as much as expected.
Seen as a bright spot in a troubled coastal economy, seaweed cultivation must overcome many obstacles to become big business in Alaska.
A volunteer program in Saanich, B.C., is helping to beat back invasive species on the island.
Harmful algal blooms will become a more common feature of a warming Arctic. Last summer, a massive bloom was detected off the coast of Western Alaska, almost by chance, when scientists sailing through the Bering Strait and Chukchi Sea found worryingly high levels of Alexandrium catenella.
Underwater forests, such as kelp forests, have been found to cover a large area and have the potential to absorb significant amounts of carbon dioxide, making them important in addressing the climate crisis, although more research is needed to understand their long-term carbon sequestration capabilities.
As the driest summer in Seattle’s record books ended, trees across the city were sounding silent alarms. It was the latest in a string of Seattle summers in the last decade, including a record-breaking heat dome in 2021, to feature drier conditions and hotter temperatures that have left many trees with premature brown leaves and needles, bald branches and excessive seeding –- all signs of stress.
