Aging infrastructure and climate change leave power grid vulnerable

Climate change and poor maintenance of the power grid are intensifying wildfires like the 2024 Smokehouse Creek fire, which devastated Texas, destroyed homes, and took two lives.

Taylor Dorrell reports for Outrider.


In short:

  • The Smokehouse Creek wildfire, sparked by a utility company’s equipment, burned over a million acres and killed two people in Texas.
  • Experts say the U.S. power grid is outdated, built for less extreme weather, and vulnerable to the growing impacts of climate change.
  • Public ownership of utilities is being debated as a possible solution to rising energy costs and the push for a greener grid.

Key quote:

“The grid in the United States is not built for significant weather events. It's built for normal everyday usage based on a climate of the 1950s or 1960s. The increased heat is contributing to outages and causing challenges of extreme heat for utility workers.”

— Jim Harrison, director of renewable energy at the Utility Workers Union of America

Why this matters:

As climate change drives more extreme weather, aging power infrastructure increases the risk of catastrophic events like wildfires. Without major upgrades to the grid, the U.S. faces rising costs, energy instability and public safety concerns.

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.
