Just a three hour drive from the ongoing international climate negotiations taking place in Warsaw, Poland, a natural gas pipeline explosion on Thursday killed two people and injured 13 others, revealing a deadly irony within the pervasive dangers—both local and planetary—presented by humanity’s continued dependency on fossil fuels.

The pipeline disaster, which generated a fireball that incinerated a row of houses, “occurred in the early afternoon in the western village of Jankow Przygodzki,” the Associated Press reports.  “[Local TV news] footage showed yellow flames and black smoke billowing above the village’s rooftops and some houses on fire. They were still burning hours after the blast.”

According to a nearby hospital, one adult and one child remain in critical condition.

Malgorzata Polkowska, a spokeswoman for the Gaz-System S.A. corporation which operates pipeline, called the explosion “a very large-scale tragedy.”
