- Efforts to save kelp forests from ocean warming are ramping up
Kelp forests, critical biodiversity hotspots, are declining rapidly due to ocean warming, pollution, and urchin overpopulation. Tribal volunteers from the Haida Nation in British Columbia are removing purple sea urchins to protect kelp, while scientists highlight kelp's underappreciated potential to sequester carbon, comparable to tropical rainforests.
- They call it stupid hot for a reason: Heat muddles animal brains
Heat waves impair animal cognitive abilities, as shown by experiments with southern pied babblers struggling to solve problems in high temperatures. This cognitive decline in animals, linked to climate change, threatens survival and ecosystem stability by disrupting behaviors like foraging and predator avoidance.
