Essentially, through Democratic and Republican administrations, we've done far too little. There are a few comprehensive state-level plans: California is acting, and environmental justice groups in New York State, for instance, have painstakingly put together a Climate and Community Protection Act that's a model for others.
But at the federal level, where it really counts, we've fallen farther and farther behind the physics of climate change.
Which brings us back to Ocasio-Cortez. Her plan for a Green New Deal--endorsed "in concept" in recent days by one presidential aspirant after another--is among the first Washington efforts to approach climate change at the right scale.
The call to get off fossil fuel by the 2030s is hard but technically achievable; the guarantee of a job in the renewable industry to anyone who wants one would actually provide the labor required to make a transition of this magnitude.
Backers plan two years of hearings to shape the final package--but if we follow their lead, get ready to follow European nations away from gas-powered cars, and prepare for public transit to get a serious shot in the arm.
Since some have begun calling her by initials now, it's worth comparing AOC to that other New Yorker, FDR.
The young people of the Sunrise Movement, who have done the most to push the Green New Deal, and who enlisted Ocasio-Cortez in their gutsy Capitol Hill protests, are far closer to meeting the scientific requirements of the moment than the various luminaries (Michael Bloomberg, George Shultz, James Baker) who propose what they consider "politically realistic" grab bags of carbon taxes and regulatory overhauls.
Not only have those gone nowhere politically, but they wouldn't make enough change fast enough. In the end, after all, global warming is a math problem.
Since some have begun calling her by initials now, it's worth comparing AOC to that other New Yorker, FDR. His New Deal morphed over time as some initiatives floundered and others flourished. But what stayed the same--and what made the difference--was the scale. He was attacking the problem of the Great Depression with programs of great size.
There are other similarities too, I think, not least among them the joy that they each bring to the task. (If you want to see the World War II-era equivalent of AOC's dance, take a look at FDR's discussion of "my little dog Fala").
The great governmental gift lies in figuring out first what needs to happen and then at figuring out what is required to meet that need, both in terms of policy and in terms of politics. Ocasio-Cortez can apparently do it backwards, and in heels.
