50 years in the making: Why it took US Congress so long to act on climate

In interviews, Gore and other veterans of the nation’s failed attempts at climate legislation pointed to several reasons that a climate bill is about to become law at last — passing the Senate by a razor-thin majority of 51-50, with the tiebreaking vote of Vice President Kamala Harris.

All said that the incontrovertible evidence that climate change has already arrived — in the form of frighteningly extreme wildfires, drought, storms and floods afflicting every corner of the United States — has helped build political support. Increasingly, the sheer volume of real-time data has overwhelmed the well-financed, multidecade strategy of oil, gas and coal companies to sow doubt about the severity of climate change.

But they also pointed to a shift in strategy, which set aside what experts consider the most efficient way to cut carbon dioxide emissions, a tax on pollution, for the less-effective but more politically palatable approach of monetary incentives to industries and consumers to switch to clean energy. Essentially, lawmakers replaced the sticks with carrots.

William Nordhaus, who first conceived of the carbon tax as a young economist at Yale University in the 1970s, wrote in an email, “Carbon taxes have proven a toxic mix with politics, although the toxicity varies across countries. Subsidies, by contrast, are catnip to the elected.”

President Joe Biden has promised that the United States will stop adding carbon dioxide to the atmosphere by 2050. All major economies must follow suit to constrain average global temperature rise to 1.5 degrees Celsius above preindustrial levels, scientists say. That’s the threshold beyond which the likelihood increases significantly of catastrophic droughts, floods, wildfires and heat waves. The planet has already warmed an average of about 1.1 degrees Celsius.

False Starts

A few years after Moynihan’s memo to the Nixon White House, Nordhaus proposed an elegant solution: governments should put a tax, fee or some other price on carbon pollution.

He would later receive the Nobel Memorial Prize in Economic Sciences for showing that “the most efficient remedy for problems caused by greenhouse gases is a global scheme of universally imposed carbon taxes.”

By 1988, climate change had started making headlines. James E. Hansen of NASA told a Senate committee that human-caused global warming had already begun. The next year, Hansen testified before a Senate subcommittee chaired by Gore, who sensed momentum was building to pass a law to stop the planet from warming any further.

As vice president in 1993, Gore helped promote a measure that would accomplish the same thing as a carbon tax.

But after the bill passed the House, Republicans attacked it as an “energy tax” and the Senate never took it up. The following year, Republicans promised to lower taxes and reform government and won control of both houses of Congress for the first time since 1952.

“It was kind of crazy, because Clinton and Gore made the House vote for the thing even though it was suicide,” said Paul Bledsoe, who was a Senate staffer at the time and later worked in the Clinton administration. “That set back climate politics for more than a decade. It was politically devastating.”

Climate policy remained dormant in Washington until 2009, when President Barack Obama tried again with a “cap-and-trade” bill. While not a direct carbon tax, it would have placed a shrinking cap on the amount of carbon dioxide pollution that could be emitted each year and forced industries to pay for permits to pollute.

History repeated itself. The measure passed the House but within days Republicans labeled it an “energy tax.” Although Democrats controlled both houses of Congress, the Senate never took up the bill, unable to muster enough votes in their own party to pass it in the face of Republican opposition.

Sen. Sheldon Whitehouse, D-R.I., recalled Sen. Harry Reid of Nevada, then the majority leader, telling him in July 2010 that there would be no further efforts to move climate legislation.

Democrats had fought hard to enact the Affordable Care Act “and they didn’t want any more conflict,” Whitehouse said Reid told him.

The aftermath “was a long, grim period,” Whitehouse said. In 2012, he began making almost weekly speeches from the Senate floor, continuing to this day, warning about the dangers of global warming.

“I just decided, look, we’re not going to stop talking about climate change in this place,” he said.

Shifting Politics and Another Chance

As efforts on Capitol Hill to address the climate crisis sputtered and stalled, the politics were beginning to shift, according to activists and lawmakers.

The evidence of climate change became increasingly visible in congressional districts, with powerful storms causing death and destruction, a megadrought threatening water supplies, and dangerous heat waves taxing electrical grids.

A major 2017 scientific report, the National Climate Assessment, detailed the economic cost of climate change, from record wildfires in California, crop failures in the Midwest and crumbling infrastructure in the South. Over the past five years the United States has experienced 89 weather and climate disasters with damage of more than $1 billion each, costing the nation a total of $788 billion and 4,557 lives, according to the National Oceanic and Atmospheric Administration. Last summer was the hottest on record in the contiguous United States, but it is on pace to be outstripped this summer.

By and large, Republicans stopped denying the planet is warming and instead objected to climate action on economic grounds.

At the same time, the plunging cost of natural gas and renewable energy has weakened the coal industry. Environmentalists forged alliances with groups they had previously sparred with, like unions and farmers. They began to talk about climate change not only as a threat to polar bears and coastlines, but also as an opportunity for the United States to develop a new economy untethered to fossil fuels.

“The movement had to mature,” said Sen. Brian Schatz, D-Hawaii, who fought back tears immediately after Sunday’s vote. “There’s plenty to catastrophize about, but that was no way to build political momentum. We started to try to answer the question, ‘What’s in it for me if we take climate action’ as a farmer, a surfer, a blue collar union worker.”

Biden took that cue, equating climate action with jobs when he won the White House in 2020, partly with help from a record turnout of young, climate-minded voters.

But Joe Manchin, the Democrat from coal-rich West Virginia and a crucial swing vote in an evenly divided Senate, would determine the limits of what was possible.

As Democrats sought to advance a broad spending bill that would include climate provisions, senators took one last stab at putting a price on carbon. They tried to include a measure that would have rewarded electric utilities that replaced fossil fuels with clean sources of energy and penalized those that did not. That provision would have enabled the United States to meet Biden’s long-term climate goals, and rapidly transform the nation’s energy sector.

Manchin rejected the plan.

In mid-July, Manchin appeared once again to scuttle negotiations, but two weeks later announced a surprise agreement with Sen. Chuck Schumer, D-N.Y., the majority leader.

The final bill includes a modest short-term fee for excess methane, a potent greenhouse gas, emitted from oil or gas operations. But lawmakers abandoned a carbon tax, at least for now. Still, most Democrats called it a critical first step.

It breaks “this logjam we’ve been living with forever,” said Sen. Tina Smith, D-Minn.

“A better world is possible. That’s been what I’ve worked for all these decades,” said Sen. Edward Markey, D-Mass., who wrote the failed 2009 cap-and-trade bill when he served in the House.

Democratic lawmakers said they expected the Biden administration would issue additional regulations to curb carbon pollution from power plants, automobiles and oil and gas wells. And some, like Whitehouse, said they hope that Congress would eventually approve a carbon tax, noting that a few Republicans, including Sens. Mitt Romney of Utah and Lindsey Graham of South Carolina, are willing to discuss it.

Whitehouse recently gave his 285th Senate floor speech on the climate crisis, speaking in front of the same worn green sign proclaiming “Time to Wake Up” that has served as a backdrop to his soliloquies for a decade. Despite finally witnessing the passage of major climate legislation, he has no plans to stop. “We’re still not on a pathway to safety,” he said.

Nordhaus agreed. “A journey does begin with a single step,” he said. “But if this is the last step, then we are in for a fiery future.”
