According to scientists, these extreme weather events are not “natural” disasters. A team of researchers already published a study finding that the Fourth of July heat wave would have been “virtually impossible” but for the climate crisis. Other studies – using methods recently validated by the National Academy of Sciences, the country’s top scientific advisory body – found that the pollution from individual big oil companies such as ExxonMobil, Chevron, Shell and BP made some past climate-exacerbated heatwaves at least 10,000 times more likely compared with preindustrial levels.

Big oil’s role in these disasters was no accident. Decades ago, these companies were predicting that their fossil fuels would cause, in their own words, “globally catastrophic” climate harms that would create “more violent weather” and........
