This week, the United Nations released a damning report. The short version: We have about 12 years to actually do something to prevent the worst aspects of climate change. That is, not to prevent climate change—we're well past that point—but to prevent the worst, most catastrophic elements of it from wreaking havoc on the world's population. To do that, the governments of Earth need to look seriously at the forces driving it. And an honest assessment of how we got here lays the blame squarely at the feet of the 1 percent.

Contrary to a lot of guilt-tripping pleas for us all to take the bus more often to save the world, your individual choices are probably doing very little to the world's climate. The real impact comes on the industrial level, as more than 70 percent of global emissions come from just 100 companies. So you, a random American consumer, exert very little pressure here. The people who are actively cranking up the global thermostat and threatening to drown 20 percent of the global population are the billionaires in the boardrooms of these companies.

There are probably no individuals who have had a more toxic impact on public and political attitudes about climate change than the Koch brothers, and it would take an absurd amount of space to document all the money and organizations they've scraped together for that purpose. (Investigative reporter Jane Mayer's groundbreaking Dark Money does basically that.) And they have every reason to: In her book, Mayer notes that "Koch Industries alone routinely released some 24 million tons of carbon dioxide into the atmosphere a year."

But the scope goes far beyond merely sowing dissent and skepticism. While billionaires and the companies they run have spent years insisting that climate change either doesn't exist or is overblown, they've known the reality of the situation for a long time. PayPal cofounder Peter Thiel, for example, used to donate to the Seasteading Institute, which aimed to build floating cities in order to counteract rising sea levels. And Exxon Mobil allegedly knew about climate change in 1977, back when it was still just Exxon and about 11 years before climate change became widely talked about. Instead of acting on it, they started a decades-long misinformation campaign. According to Scientific American, Exxon helped create the Global Climate Coalition, which questioned the scientific basis for concern over climate change from the late '80s until 2002, and successfully worked to keep the U.S. from signing the Kyoto Protocol, a move that helped cause India and China, two other massive sources of greenhouse gas, to avoid signing.

Even when Republican lawmakers show flashes of willingness to get something done, they're swiftly swatted down. There are myriad examples, but one example comes via Dark Money, where Mayer describes an incident in April 2010 when Lindsey Graham briefly tried to support a cap-and-trade bill: A political group called American Solutions promptly launched a negative PR campaign against him, and Graham folded after just a few days. American Solutions, it turns out, was backed by billionaires in fossil fuel and other industries, including Trump-loving casino magnate Sheldon Adelson.

In recent years, fossil-fuel companies have tried to cast themselves as being on the same side of the general public. Just this month, Exxon pledged $1 million to fight for a carbon tax, a stopgap measure that charges a fee of $40 per ton of carbon produced and increases as production goes up. At a glance, that may seem magnanimous, but the truth is that Exxon can afford the tax. Not only is the oil and gas industry experiencing a serious boom right now, companies know that the only real solutions to climate change will hurt them even more than a measly tax.
