The daughter of a woman who died during the 2021 Pacific Northwest heat wave is suing seven oil and gas companies for her mother’s wrongful death. Juliana Leon died of hyperthermia, or overheating, as a “heat dome” choked the region and sent temperatures in Seattle skyrocketing to 108 degrees. Nearly 200 people died during the heat wave. The lawsuit is the first of its kind and accuses the fossil fuel companies of concealing their role in creating the climate crisis and failing to warn people of the dangers of their emissions.

This comes as a new report today found half the world population endured 30 additional days of extreme heat over the past year due to human-created climate change.
