The year is coming to a close, which means us bloggers are obliged to do a year-end post, looking back on the year’s events and looking ahead to what’s next. I’ll be honest, I had second thoughts about whether to publish this post at all — my outlook is pretty gloomy and I don’t want to be a spreader of gloom — but I figure you pay me for the straight scoop. So here it is.The broad story is that, as bad as it sometimes felt going through it, we are coming to the end of the most productive year of federal climate politics that any of us are likely to experience for a long, long time. I’m not sure it ever really sank in with most people, including Democrats in Congress, but this was the last big shot. After the Build Back Better Act passes (if it passes), that will be it for federal climate legislation. After that, those of us hoping for climate progress will have to forget about first-best solutions and begin thinking in terms of guerrilla actions, in states, cities, and the private sector. That’s a very different mindset than the push for a centralized solution.Let’s begin with a quick review of the events of the last year.Democrats’ inevitably disappointing legislation limps toward the finish lineJoe Biden entered his first term as president in an impossible situation. He was swept into office on a wave of high hopes, given total Democratic control over the federal government, in the wake of an election marked by expansive policy promises and record voter turnout. At the same time, his majority in the Senate — salvaged by the two miraculous Democratic wins in Georgia — is razor-thin. Given the effectively automatic use of the filibuster by Republicans these days, absent filibuster reform, Democrats simply can’t pass bills under regular order. They can only pass bills through budget reconciliation, and even on that, they need the votes of every single one of their senators to do anything. Given that basic structure, disappointment was inevitable. Biden and the Democrats started strong out of the gate. Congress delivered the Covid relief bill. Biden issued a flurry of executive orders. Vaccination rates began rising. As long as Democrats were doing stuff, taking action, controlling the news cycle, Biden’s approval rating held up.Around July-August, two things happened. First, Biden withdrew US troops from Afghanistan, after which the Taliban quickly took control, sparking an extended wave of hysterically negative mainstream press coverage. (Coverage of Biden in right-wing media was, of course, hysterically negative on day one and has been ever since.)Second, legislative action ground to a halt and segued into months of frustrating negotiations, which continue to this day.They split their big bill in two, allowing a bipartisan group of senators to hash out a roads-and-bridges infrastructure bill (the bipartisan infrastructure framework, or BIF) while leaving everything else to a second bill. The idea was to give Sens. Joe Manchin (D-WV) and Kyrsten Sinema (D-AZ) their bipartisan achievement, but to require that they pass it alongside a Dems-only reconciliation bill, the Build Back Better Act (BBB). At the time, Democrats from Biden and Senate Majority Leader Chuck Schumer (D-NY) and House Speaker Nancy Pelosi (D-CA) on down pledged that the BIF would not pass without the BBB. The bills were a single package, they all emphasized. “It's going to be either both or nothing,” Sen. Bernie Sanders (I-VT) said.What happened instead is that the bipartisan group put together a relatively bare-bones bill and got it passed through the Senate. That put immense pressure on the House to follow suit, despite everyone’s pledges. The progressive caucus, led by Rep. Pramila Jayapal (D-WA), held together and refused to pass the BIF for as long as it could, but in November, it relented and the House passed the bill. Progressives voted for the BIF based on a promise from Biden that he could secure Manchin’s vote for the BBB in something close to its
