"You likely remember the 2023 Maui wildfires, a tragedy that killed more than 100 people and destroyed nearly 2,000 homes, all but erasing a historic island community. You may also remember that the fires began when a broken power pole owned by the local electric utility sparked against dry vegetation on a windy day.
But do you really know that? Were you there? How can you prove it?
In the aftermath of the Maui fires, thousands of people across all the major social media platforms shared posts and videos alleging that the fires had a more sinister origin. They posited that the government had used a “direct energy weapon,” or a form of laser, to ignite the area. Depending on the post you saw, this was part of a plot to reclaim the area for a high-speed rail line, or a high-tech “smart city.” A number of right-wing activists and social media personalities amplified these claims, including the late Charlie Kirk. At the same time, the Federal Emergency Management Agency saw accounts linked to China circulating rumors that a “weather weapon” had caused the fires. Other accounts alleged that the agency was going to seize the homes of people in Maui who applied for emergency aid, a claim that raised traumatic memories of colonization in a community with significant Indigenous historical and cultural ties.
Extreme weather events are always chaotic, and it’s always been easy for rumors to spread during moments of calamity, but the problem has never been as bad as it is now. The escalating pace of climate change has produced a series of supercharged wildfires, rapidly intensifying hurricanes, devastating drought, and sudden floods, all of which plunge communities into confusion and disarray. At the same time, the information landscape has never been more fragmented — major social media companies have given up on any pretense of fact-checking and content moderation; politicians often distort or politicize disasters; government agencies are short-staffed following DOGE cuts; and generative AI models have created an entirely new and little-understood way to source information. It’s not just your weird uncle seeing these rumors on Facebook: A recent report from the News Literacy Project found that a vast majority of teens encounter social media conspiracies, and a vast majority of teens who encounter those theories are inclined to believe them."
