Jim Salter at Ars Technica: "Learn to think in sed, awk, and grep"

Saltar provides an overview of redirection and three commonly used command line tools in a nice article at Ars Technica. While these may seem like esoteric utilities, they can be truly useful for a variety of data cleaning and processing tasks. While the article doesn't provide a comprehensive overview of the commands -- it would be impossible to do so in anything short or readable -- it does help one understand how the commands work and how they can be used. A recommended, quick read and longer-term reference. (h/t sixcolors.com)

Deregulation in the Trump era - and rolling it back

A lot has been made, rightly so, in recent days of President Biden's rollbacks of the Trump Administration's gleeful dismantling of environmental, health, and other regulatory safeguards. Both the NYT and Brookings have been keeping track of what's happening on the regulatory front, with Brookings doing so since at least 2018 if not earlier.

Brookings breaks down the regulatory changes into 12 discrete categories, spanning topics from COVID to Environment to Telecommunications.

NYT focuses on >100 Environmental regulations and rules rolled back by the Trump administration.

Both sources are interesting and useful. I'm looking for an analog for the current administration -- a rollback of rollbacks tracker, if you will.

Washington Post: If I were still working at the EPA, I would resign

Bernard D. Goldstein, former chairman of the Clean Air Scientific Advisory Committee and EPA assistant administrator for R&D under Reagan:

I had hoped that Wheeler would reverse Pruitt’s initial policies. Instead, he has taken them well beyond the point that, were I a member of CASAC, I would have resigned. Neither my conscience, nor my concern for the respect of my peers, would have allowed me to provide advice on a complex health-related subject when I cannot interact in a scientific consensus advisory process with those who have the necessary expert credentials.

I cannot ask President Trump’s EPA assistant administrator for research and development to resign. That position remains unfilled. Nor is it likely that any credible scientist would accept such a nomination. But I urge the current members of CASAC to step down rather than seemingly acquiesce to this charade. The EPA’s leadership is destroying the scientific foundation of environmental regulations, to the detriment of the health of the American people and our environment.

Science vs Fringe Thinking: EPA Science Panel Considering Guidelines That Upend Basic Air Pollution Science

NPR, reporting on a recent EPA Meeting:

At a public meeting Thursday that ran nearly two hours long, multiple members of that committee, including Chair Tony Cox and Steven Packham of the Utah Division of Air Quality, said they do not agree that breathing air polluted with soot can lead to an early death.

“[Committee] members have varying opinions on the adequacy of the evidence supporting the EPA’s conclusion that there is a causal relationship between [particulate matter] exposure and mortality,” said Cox, reading from the committee’s draft recommendations before explaining that he is “actually appalled” at the lack of scientific evidence connecting particulate pollution to premature death.

From Nature:

A quarter of a century of research has shown that breathing in fine airborne particles emitted by cars, power plants and other sources shortens people’s lifespans. But that scientific consensus is now under attack from a top advisor to the US Environmental Protection Agency (EPA), just as the agency is rushing to revise the national air-quality standard for such pollution before the end of President Donald Trump’s first term. Scientists fear that the result could be weaker rules on air pollution that are bad for public health — and based on politics, not science.

The case has been made — repeatedly — that the health and economic benefits of the Clean Air Act and subsequent regulatory processes are clear. This is summarized succinctly in the figure below, which shows energy consumption, vehicle miles traveled, GDP, and total emissions of EPA criteria pollutants.

Figure from The Lancet Commission on Pollution and Health

Let’s put aside the economic argument and focus on the principles that undergird the Clean Air Act - protection of public health, with standards set to protect the most vulnerable. This critical prerogative is undermined by these (and other) recent efforts to roll back regulations that have clear and demonstrable health benefits. This is yet another example of the Trump administration’s abnegation of responsibility to the health and welfare of the US population.

For more information, see Gretchen T. Goldman and Francesca Dominici’s discussion in Science and their claim-by-claim evidence base. See also a nice summary of the issue at NRDC and a letter from Professor John Samet to the EPA that comprehensively outlines issues with changes to the evidence review process for the National Ambient Air Quality Standards.

Some more graphs of Beijing's Air Pollution

A bunch of folks across the internet have been doing some great stuff with the air quality data coming out of China via official channels and the US Embassy twitter feeds. My advisor asked for some graphs of available data. They are posted below (all were created in R using ggplot2). If time ever permits, I’ll post some interactive visualizations.

Lisa Jackson on the Moth

Lisa Jackson, former EPA Administrator, tells an audience at the Moth about how she transitioned into Environmental Engineering. Great story.

Not compromise, but capitulation.

In a letter to Lisa P. Jackson, the E.P.A. administration, the head of the White House office of regulatory affairs, Cass Sunstein, said that the president was rejecting her proposal to tighten the standard.

"He has made it clear he does not support finalizing the rule at this time," Mr. Sunstein said.

He said that changing the rule now would create uncertainty for business and local government. He also said there was no compelling reason to rewrite the ozone standard in advance of the scheduled reconsideration in 2013, a key demand of business interests.

Mr. Sunstein told Ms. Jackson that since the rule is due for reconsideration in 2013, an earlier review would promote confusion and uncertainty.

"In this light," he wrote, "issuing a final rule in late 2011 would be problematic in view of the fact that a new assessment, and potentially new standards, will be developed in the relatively near future."
