A discussion of different approaches to climate policy
Last week, the U.S. government released the Fourth National Climate Assessment which outlined the dire economic and environmental consequences of climate change. Instead of highlighting key findings of the report—two good summaries are available here and here—we'll contextualize the current climate debate within legal history, which shows the limitations of current economically-focused arguments for climate policy.
A 2010 Yale Law Journal article by Jedediah Purdy situates the current climate debate within the long tradition of political argument about the natural world, and challenges assumptions that environmental values which appeal to moral and civic duty are too weak and vague to spur political action. In fact, Purdy argues that major environmental legislation emerged from "democratic argument over the value of the natural world and its role in competing ideas of citizenship, national purpose, and the role and scale of government." Purdy does more than just argue that environmental public language is more coherent than conventionally understood, he argues that understanding climate policy through economic self-interest diminishes the role political struggle plays in shaping national values and interests:
"Consider one example that makes little sense through the lens of narrow self-interest, much more as part of an ongoing debate over environmental values: the organizing project that has led 1015 city governments to adopt the goals of the Kyoto Protocol (a seven percent reduction in greenhouse-gas emissions from 1990 levels by 2012) through an instrument called the Mayors Climate Protection Agreement. Since the costs are not zero, and the benefits, in theory, are almost exactly that, the question of motivation is still fairly sharply presented.
In private interviews and public statements, city officials explain their efforts in several ways. They are quick to cite the advantage certain regions hope to enjoy from early adoption and manufacture of technologies that may later become standard. They embrace a simple public-choice motive: city governments hope to benefit from green-development block grants and, in the longer term, density-friendly economic development, and early efforts may position them to do both.
They also regard themselves as engaged in political persuasion that they hope will induce others to take similar action. Whether this is plausible is partly endogenous to the politics itself. This politics seeks to affect the reasons—specifically those grounded in environmental values—that people understand themselves to have for joining collective undertakings. Rather than a specimen of an independently established logic of collective action, it is an engagement with that logic itself."

- In a 2018 article, Purdy looks more deeply at the history of environmental justice, and why its concerns were left out of mainstream environmental law: "Mainstream environmental law was the last major legal product of 'the great exception,' the decades of the mid-twentieth century when, unlike any other time in modern history, economic inequality was declining and robust growth was widely shared." Link.
- The new climate reports have brought attention back to solar geoengineering, which the Guardian, covering a Gernot Wagner paper, notes is extremely inexpensive and possibly an option for desperate circumstances: "The IPCC [Intergovernmental Panel on Climate Change] report said geoengineering might be adopted as a temporary "remedial measure" in extreme circumstances." Link.
- A 2017 dissertation examines the environment as an object of politics, as opposed to natural capital, and argues that the environment is a "political problem that entails ongoing negotiations over the legitimacy of market rule, the role of the state in relation to the market, and the value of ecological stewardship." Link.
- "Although the EITC is one of the largest and most important public assistance programs in the U.S., we show that the EITC is actually one of the least expensive anti-poverty programs in the U.S., costing taxpayers about half as much as the school lunch and breakfast programs." Link.

"Many parents are saddled with large debt burdens, ultimately repaying just enough to avoid default and sometimes owing significantly more than their initial balance." Link.
- A summary of a new World Bank report on the future of work: "The report argues that, on balance, concerns about robot-induced unemployment appear to be unfounded. Instead, the future of work is driven by the competing forces of automation and innovation, the other ‘AI.'" Link. ht Sidhya
- New research explores whether Congressional staff actually recognize the opinions of their members' constituents. Among the findings: "Staffers who rely more heavily on conservative and business interest groups for policy information have more skewed perceptions of constituent opinion." Link.
- A new paper evaluates to what degree public policy represents mass public preference in the United States and finds that "policy outcomes are more conservative than preferences in each state."Link. Related, a recent paper by David Broockman and Christopher Skevron examine the misperception of constituency opinion among political elites. Link.

- JW Mason posted a long version of his Jacobin article on "how a decade of crisis changed economics": "It’s probably a mistake to see economists primarily as either carriers of valuable technical expertise or systematic expositors of capitalist ideology. They are participants in public debates just like anyone else. The profession as the whole is more often found trailing after political developments than advancing them." Link.

- Using genomes to find the path of the plague: "We describe five genomes from the second half of the 14th century ... Corroborated by historical and ecological evidence, the presented phylogeny could support the hypothesis of an entry of plague into Western European ports through distinct waves of introduction during the Medieval Period, possibly by means of fur trade routes, as well as the recirculation of plague within the human population via trade routes and human movement."Link.
