Billionaire industrialist David Koch, who spent vast sums of his billions in personal fortune promoting climate denialism and other right wing causes over the last four decades, died Friday at 79.
His legacy in modern American politics was summed up by The New York Times:
Three decades after David Koch's public steps into politics, analysts say, the Koch brothers' money-fueled brand of libertarianism helped give rise to the Tea Party movement and strengthened the far-right wing of a resurgent Republican Party.
Koch was a controversial figure. His vast fortune—made in large part through fossil fuel extraction and manufacturing, though the company has interests in nearly everything—made him and his brother Charles two of the richest people in the world. The brothers spent at least $100 million since the 1970s promoting right-wing causes, and David ran for vice president as a member of the Libertarian Party in 1980.
One of the causes Koch dumped his fortune into promoting was climate crisis denialism.
By making vast sums of money from destroying the planet and then fighting against efforts to stem the flow of the crisis, tweeted Native American activist Tara Houska, Koch was a double damage denialist.
"Let's not forget the massive network of oil pipelines, refineries, and fossil fuel expansion projects that David Koch was directly responsible for," said Houska. "He funded climate deniers while he contributed to climate change, in the range of a 300 million ton carbon footprint annually."
On Twitter, HuffPost environmental reporter Alexander Kaufman noted the irony of Koch dying as the effects of the climate crisis the billionaire activist had a large hand in perpetuating are being increasingly felt around the globe.
"He deployed his stupendous fortune funding climate denial in the years when the science was clear and there was still time to avert catastrophic warming," said Kaufman. "He died as fires raged from the Amazon to the Arctic."
In a piece for Earther, Brian Kahn wrote that Koch and his brother's funding of the movement to obfuscate the costs of the climate crisis made them even more than the "arch-villains" they were from funding other right-wing causes. And, said Kahn, David Koch now gets to avoid the consequences of his actions.
"Climate change is a form of violence that will largely affect people with little power to address it or relatively little role in creating it," wrote Kahn. "Death is an escape hatch for David Koch while the rest of us are left scrambling for the emergency brake before we go over the cliff."
Koch's libertarianism led him to take some positions—such as his support of gay marriage and opposition to the war on drugs—that might make his legacy seem mixed. But, as media critic Adam Johnson pointed out, that's "trivial" in the context of Koch's full record.
"People will try to be nice and note David Koch opposed the war on drugs/militarism," Johnson tweeted, "but the money he gave opposing these twin evils was trivial compared to the funds he gave supporting candidates that backed the war on drugs/militarism and the related ideology of starving poor people."
The Koch borthers' reported antipathy to President Donald Trump, Jack Mirkinson wrote at Splinter, was hardly enough to offset the damage they did by promoting the Republican Party.
"The Kochs were not happy with everything Donald Trump did, but that is a low standard for anyone walking the planet—and anyway, they loved his tax plan," wrote Mirkinson.
The Intercept's Mehdi Hasan said on Twitter that Koch will be remembered in the short term for his wealth, philanthropy, and work to advance right-wing causes. But, Hasan said, that pales in comparison to his role as a "climate denier."
"That'll be his long-term legacy," said Hasan, "funding the effort to downplay an existential threat to all of us."
