Noatak Revisited
- Returning to the Noatak River after 30 years, Waterman found it dramatically changed: flooded, warm enough to swim in, and unusually mosquito-infested in late August.
- He observed significant brush growth due to the "greening" of the Arctic, highlighting the radical environmental shifts.
Permafrost Thaw
- The thawing permafrost, described as "frozen spinach left out on the counter," releases ancient plant matter.
- Microbes consuming this matter release carbon dioxide and methane, accelerating the climate crisis.
Wildlife Impacts
- Climate change impacts Arctic wildlife in complex ways; while some species decline, others surge.
- Caribou, a keystone species, are diminishing across the Arctic due to habitat loss and changing conditions.
