Projected increases are most prominent in the Western US, with smaller changes elsewhere. Future mortality burden is also dependent on population and baseline death rate changes.
The Salmon River and many of its tributaries in Alaska's Brooks Range now have toxic levels of metals, exceeding EPA safety thresholds for aquatic life. This contamination, likely due to thawing permafrost exposing sulfide minerals, may explain the recent dramatic decline in chum salmon returns to this watershed, impacting local communities dependent on the salmon for both livelihood and sustenance.
Amazonian freshwaters are critical for global climate, harbor exceptional biodiversity, and support millions of people, but they often get overlooked compared to the Amazon rainforest. The authors emphasize the interconnectedness of the Amazon's hydroclimate, biodiversity, and human dimensions, advocating for a more holistic approach to conservation that prioritizes freshwater ecosystems alongside their terrestrial counterparts.
