Alaska’s St. Paul Island struggles to survive as warming seas erase ice and upend life

On St. Paul Island in the Bering Sea, rising temperatures and disappearing sea ice have shattered the local economy, unraveled the community, and left residents fighting to preserve their way of life.

Joshua Partlow and Carolyn Van Houten report for The Washington Post.


In short:

  • Warmer waters around St. Paul Island led to the collapse of crab populations, the shutdown of the island’s major crab processing plant, and severe municipal budget cuts.
  • The absence of winter sea ice has accelerated coastal erosion, destroyed traditional hunting grounds, and threatened historic sites such as the island cemetery.
  • Scientists warn that continued climate-driven disruptions could erase decades of fisheries research and further imperil the island’s fragile ecosystem.

Key quote:

“We’re not freezing in the winter like we used to be.”

— Aaron Lestenkof, environmental monitor and Aleut resident of St. Paul Island

Why this matters:

The rapid warming of the Bering Sea and its devastating effects on St. Paul Island offer a stark glimpse into how climate change can dismantle a community’s fabric without warning. The collapse of snow crab populations, loss of sea ice, and crumbling infrastructure show how environmental changes hit hardest in isolated, Indigenous communities that depend directly on natural resources for survival. The environmental shifts also reverberate beyond the island, destabilizing fisheries that supply food across the United States and undermining decades of scientific understanding.

Toxic chemicals and climate change work together to harm fertility across species

In a recent review published in NPJ Emerging Contaminants, researchers examine how toxic chemicals can reduce fertility in both humans and wildlife, and how these effects are worsened by climate change.


In short:

  • Animals - including insects, fish, reptiles, birds, humans, and other mammals - are constantly simultaneously exposed to synthetic chemicals and the impacts of climate change, including rising temperatures.
  • Both of these stressors can harm fertility, and many of the impacts found are similar across species, such as effects on sperm and eggs.
  • The stress caused by these exposures also impacts overall health, harming animals’ ability to adapt to a changing environment and worsening global biodiversity loss.


Key quote:

“To build a sustainable future, we must recognize that chemicals, once released, don’t simply disappear. Instead, they contribute to the larger issue of driving humanity towards the exceedance of planetary boundaries when considered in combination with climate change and other planetary-level impacts.”


Why this matters:

While climate change and toxic endocrine disrupting chemicals (EDCs) are both individually well-established as health threats, few studies have examined the implications of the widespread simultaneous exposure experienced by humans and wildlife. Many EDCs can also impact health across multiple generations, meaning their harm continues long after the original exposure. To better tackle the issue of EDCs, the authors of this study emphasize the need for strong regulations that address chemicals by class, rather than individually.
