When Bucks County, Pennsylvania, filed a lawsuit last week against major oil and gas companies for climate damages, Commissioner Chair Diane Ellis-Marseglia pointed to “unprecedented weather events here in Bucks County that have repeatedly put residents and first responders in harm’s way, damaged public and private property and placed undue strain on our infrastructure.” The county argues oil companies’ “campaigns to deceive and mislead the public about the damaging nature of their fossil fuel products” delayed climate action for decades, robbing communities of precious time to mitigate the climate-driven disasters they now face.
One of those disasters occurred last year, when a rainstorm in Bucks County caused deadly flash flooding that swallowed vehicles and killed 7 people, including two children. Scientists said the deluge and its aftermath — not the county’s first “100-year flood” in recent years — are a harbinger of the intense and dangerous rainstorms that a warming climate is making more likely.
As the science connecting climate change to more frequent and severe weather events becomes clearer, there is mounting evidence that members of the fossil fuel industry coordinated to downplay that link — evidence that could be valuable to lawsuits seeking accountability.
Bucks County is just one in a growing list of communities taking legal action against fossil fuel companies in the wake of deadly extreme weather events. Multnomah County, Oregon sued oil, gas, and coal majors after a 2021 heat dome that killed nearly 70 people. On the 10 year anniversary of Superstorm Sandy, New Jersey’s attorney general took Exxon, Chevron, and other oil giants to court, citing the billions of dollars in damage and deaths the hurricane caused in the state. In the first-ever racketeering lawsuit against Big Oil companies, Puerto Rico municipalities are seeking to recover costs incurred by Hurricane Maria.
Fossil fuel majors, these cases argue, should help communities pay for the costs of adapting to and recovering from climate disasters given the industry’s early research into — and subsequent denial of — their products’ harm. “We’re already seeing the human and financial tolls of climate change beginning to mount,” said Commissioner Ellis Marseglia. “If the oil companies’ own data is to be believed, the trend will continue.”
It’s a trend that the fossil fuel industry worked to obscure for decades. A collection of evidence just published to ClimateFiles.com reveals the extent to which oil companies and their trade associations sought to deny and downplay the relationship between climate change and extreme weather.
Nicky Sundt, a climate expert and former communications director for the U.S. Global Change Research Program during the George W. Bush administration, said she tried to publicly communicate the science behind that link, but was “stymied over and over again” by industry interests inside and outside the White House — an experience she has discussed with The Guardian and PBS Frontline.
“By interfering with the communications of climate science to the public, [the fossil fuel industry] knew that the public was less likely to become agitated and do something about it,” Sundt said. “The consequence was to slow efforts to reduce our emissions, and to leave us more unprepared for the impacts of climate change. The longer you wait, the more expensive it is to deal with all of these issues, and they’ve eaten up incredibly important time we needed.”
In 1997, fossil fuel interests successfully convinced prominent United States officials to oppose U.S. ratification of the Kyoto Protocol — an international climate agreement that would have limited greenhouse gas emissions decades ago.
A year later, the American Petroleum Institute (API) — the largest........
