Current Wisdom: Record Global Temperature—Conflicting Reports, Contrasting Implications

The Current Wisdom is a series of monthly articles in which Patrick J. Michaels and Paul C. “Chip” Knappenberger, from Cato’s Center for the Study of Science, review interesting items on global warming in the scientific literature or of a more technical nature that may not have received the media attention that they deserved, or have been misinterpreted in the popular press.

Despite what you may think if you reside in the eastern United States, the world as a whole in 2014 has been fairly warm. For the past few months, several temperature-tracking agencies have been hinting that this year may turn out to be the “warmest ever recorded”—for whatever that is worth (keep reading for our evaluation). The hints have been turned up a notch with the latest United Nations climate confab taking place in Lima, Peru through December 12.  The mainstream media is happy to popularize these claims (as are government-money-seeking science lobbying groups).

But a closer look shows two things: first, whether or not 2014 will prove to be the record warmest year depends on whom you ask; and second, no matter where the final number for the year ranks in the observations, it will rank among the greatest “busts” of climate model predictions (which collectively expected it to be a lot warmer). The implication of the first is just nothing more than a jostling for press coverage. The implication of the latter is that future climate change appears to be less of a menace than assumed by the president and his pen and phone. 

Let’s examine at the various temperature records.

First, a little background. Several different groups compile the global average temperature in near-real time. Each uses slightly different data-handling techniques (such as how to account for missing data) and so each gets a slightly different (but nevertheless very similar) values. Several groups compute the surface temperature, while others calculate the global average temperature in the lower atmosphere (a bit freer from confounding factors like urbanization). All, thus far, only have data for 2014 compiled through October, so the final ranking for 2014, at this point in time, is only a speculation (although a pretty well-founded one).

The three major groups calculating the average surface temperature of the earth (land and ocean combined) all are currently indicating that 2014 will likely nudge out 2010 (by a couple hundredths of a degree Celsius) to become the warmest year in each dataset (which begin in mid-to-late 1800s). This is almost certainly true in the datasets maintained by the U.S. National Oceanographic and Atmospheric Administration (NOAA) and the UK Met Office Hadley Centre. In the record compiled by NASA’s Goddard Institute for Space Studies (GISS), the 2014 year-to-date value is in a virtual dead heat with the annual value for 2010, so the final ranking will depend heavily on the how the data come in for November and December. (The other major data compilation, the one developed by the Berkeley Earth group is not updated in real time).

GOP Blocks Marijuana Reform in DC

Last November, voters in Washington, DC overwhelmingly approved a referendum that would have legalized marijuana in the city.  Now that measure has been stymied by House Republicans–led by Rep. Andy Harris (R-MD).

From today’s Washington Post: The move “shocked elected DC leaders, advocates for marijuana legalization and civil liberties groups.”

As a constitutional matter, the Congress can set policies for the District of Columbia, but this is an awful move.  No vote on marijuana reform, just override the voter-approved measure by inserting language into a gigantic spending bill.

Isn’t it interesting that such tactics never seem to be used to downsize the federal government and reduce its powers?  Why not zero out the budget for the DEA or the Export-Import Bank?

New Study Finds Minimum Wage Increases Hurt Low-Skilled Workers

A new working paper from the National Bureau of Economic Research finds that significant minimum wage increases can hurt the very people they are intended to help. Authors Jeffrey Clemens and Michael Wither find that significant minimum wage increases can negatively affect employment, average income, and the economic mobility of low-skilled workers. The authors find that significant “minimum wage increases reduced the employment, average income, and income growth of low-skilled workers over short and medium-run time horizons.”  Most troublingly, these low-skilled workers saw “significant declines in economic mobility,” as these workers were 5 percentage points less likely to reach lower middle-class earnings in the medium-term. The authors provide a possible explanation: the minimum wage increases reduced these workers’ “short-run access to opportunities for accumulating experience and developing skills.” Many of the people affected by minimum wage increases are on one of the first rungs of the economic ladder, low on marketable skills and experience. Working in these entry level jobs will eventually allow them to move up the economic ladder. By making it harder for these low-skilled workers to get on the first rung of the ladder, minimum wage increases could actually lower their chances of reaching the middle class.

Most of the debate over a minimum wage increase centers on the effects of an increase on aggregate employment, or the total number of jobs and hours worked that would be lost. A consensus remains elusive, but the Congressional Budget Office recently weighed in, estimating that a three year phase in of a $10.10 federal minimum wage option would reduce total employment by about 500,000 workers by the time it was fully implemented. Taken with the findings of the Clemens and Wither study, not only can minimum wage increases have negative effects for the economy as a whole, they can also harm the economic prospects of  low-skilled workers at the individual level.

Four states approved minimum wage increases through ballot initiatives in the recent midterm, and the Obama administration has proposed a significant increase at the federal level. This study should give them a reason to reconsider.

Details of the Cromnibus

Last night, House and Senate negotiators released the legislative text for the government’s newest spending bill, dubbed the “Cromnibus.” The bill authorizes the government to spend $1.01 trillion on discretionary programs between now and September 30, 2015. The total spending level honors last year’s Ryan-Murray budget deal, but also makes a number of important changes to federal law.

These changes include:

Environmental Protection Agency (EPA): The EPA’s funding was cut by $60 million over last fiscal year. The agency’s budget has been cut by 21 percent since fiscal year 2010.

Department of Homeland Security (DHS): Following President Obama’s executive action on immigration, Republican sought to limit funding for DHS. According to the deal, DHS is only funded through February. The incoming Congress will need to fund the agency for the remainder of the fiscal year.

Internal Revenue Service (IRS): The IRS’ budget is cut by $345.6 million.

ObamaCare: The bill does not cut funding to ObamaCare implementation, but it also does not include any new funding to the Department of Health and Human Services and the Internal Revenue Service, the two agencies with primary implementation responsibilities. The bill also limits ObamaCare’s risk corridor provision, which provided a bailout to insurance companies.

Marijuana: The District of Columbia voted overwhelmingly in November to legalize marijuana. The Cromnibus halts the legalization process.

Yucca Mountain: The bill continues funding for the proposed nuclear storage site. Earlier this year, the Nuclear Regulatory Commission confirmed Yucca Mountain’s safety.

Overseas Contingency Operations: The budget deal also provides $64 billion in funding for military operations, including $5 billion for the fight against ISIS. The $64 billion is in addition to the $1.01 trillion in discretionary spending.

Internet Tax Moratorium: The federal moratorium on state and local internet taxes continues for one year.

 

Early Childhood Summit Don’t Lie?

When I first heard about the White House Summit on Early Education being held today, I worried. “I sure hope this isn’t going to be a PR stunt to cheerlead for government pre-kindergarten programs,” I thought. Then I got the announcement: U.S. Secretary of Education Arne Duncan will be having a Twitter chat with pop sensation Shakira in conjunction with the summit! “Oh, I was just being silly,” I said to myself, relieved that this would be a sober, objective discussion about what we do – and do not – know about the effectiveness of pre-K programs.

Okay, that’s not actually what happened. In fairness to Shakira, she does appear to have a very serious interest in children’s well-being. Unfortunately, the White House does not appear to want to have an objective discussion of early childhood education.

Just look at this, from the official White House blog:

For every dollar we invest in early childhood education, we see a rate of return of $7 or more through a reduced need for spending on other services, such as remedial education, grade repetition, and special education, as well as increased productivity and earnings for these kids as adults.

Early education is one of the best investments our country can make. Participation in high-quality early learning programs—like Head Start, public and private pre-K, and childcare—provide children from all backgrounds with a strong start and a solid foundation for success in school.

Let me count the ways that this is deceptive, or just plain wrong, as largely documented in David Armor’s recent Policy Analysis The Evidence on Universal Preschool:

  • The 7-to-1 ROI figure – for which the White House cites no source – almost certainly comes from work done by James Heckman looking at the rate of return for the Perry Preschool program. It may well be accurate, but Perry was a microscopic, hyperintensive program from the 1960s that cannot be generalized to any modern, large-scale program.
  • If you look at the longitudinal, “gold-standard” research results for Head Start, you see that the modest advantages accrued early on essentially disappear by first grade…as if Head Start never happened. And federal studies released by the Obama administration are what report this.
  • It stretches credulity to call Head Start “high quality,” not just based on its results, but on its long history of waste and paralysis. Throughout the 2000s the federal Government Accountability Office and general media reported on huge waste and failure in the program.
  • Most evaluations of state-level pre-K programs do not randomly assign children to pre-K and compare outcomes with those not chosen, the “gold standard” mentioned above. Instead they often use “regression discontinuity design” which suffers from several shortcomings, arguably the biggest of which is that you can’t do longitudinal comparisons. In other words, you can’t detect the “fade out” that seems to plague early childhood education programs and render them essentially worthless. One large-scale state program that was evaluated using random-assignment – Tennessee’s – appears to be ineffective.
  • The White House says early childhood programs can help “children from all backgrounds.” Not only is that not true if benefits fade to nothing, but a federal, random-assignment evaluation of the Early Head Start program found that it had negative effects on the most at-risk children.

I suspect the vast majority of people behind expanding preschool are well intentioned, and I encourage them to leverage as much private and philanthropic funding as they can to explore different approaches to pre-K and see what might work. But a splashy event intended to proclaim something is true for which we just don’t have good evidence doesn’t help anyone.

Let’s not mislead taxpayers…or kids.

Potential Path to a Green Card in Executive Action

In a little-noticed memo on November 20th, Department of Homeland Security Secretary Jeh Johnson ordered Customs and Border Protection and Citizenship and Immigration Services to allow unlawful immigrants who are granted advance parole to depart the United States and reenter legally.  This memo is based on a decision rendered in a 2012 Board of Immigration Appeals case called Matter of Arrabally. Allowing the immigrant to legally leave and reenter on advance parole means he or she can apply for a green card from inside of the United States–if he or she qualifies. 

Advance parole can be granted to recipients of DACA (deferred action for childhood arrivals) and DAPA (deferred action for parental accountability) if they travel abroad for humanitarian, employment, or educational purposes, which are broadly defined

Leaving the United States under advance parole means that the departure doesn’t legally count, so the 3/10 year bars are not triggered, and the unlawful immigrant can apply for a green card once they return to the United States through 8 USC §1255 if he or she is immediately related to a U.S. citizen.  Reentering the United States under advance parole means that the prior illegal entry and/or presence are wiped out in the eyes of the law.  Crucially, individuals who present themselves for inspection and are either admitted or paroled by an immigration officer can apply for their green card from inside of the United States and wait here while their application is being considered.

In such a case, unlawful immigrants who receive deferred action and who are the spouses of American citizens will be able to leave the United States on advance parole and reenter legally, allowing them to apply for a green card once they return.  Unlawful immigrants who are the parents of adult U.S. citizen children will be able to do the same.  Unlawful immigrants who are the parents of minor U.S. citizen children and are paroled back into the country will just have to wait until those children are 21 years of age and then they can be sponsored for a green card.

According to New York based immigration attorney Matthew Kolken, “President Obama’s policy change has the potential to provide a bridge to a green card for what could be millions of undocumented immigrants with close family ties to the United States.” 

Debunking the Debunking of Dynamic Scoring and the Laffer Curve

Many statists are worried that Republicans may install new leadership at the Joint Committee on Taxation (JCT) and Congressional Budget Office (CBO).

This is a big issue because these two score-keeping bureaucracies on Capitol Hill tilt to the left and have a lot of power over fiscal policy.

The JCT produces revenue estimates for tax bills, yet all their numbers are based on the naive assumption that tax policy generally has no impact on overall economic performance. Meanwhile, CBO produces both estimates for spending bills and also fiscal commentary and analysis, much of it based on the Keynesian assumption that government spending boosts economic growth.

I personally have doubts whether congressional Republicans are smart enough to make wise personnel choices, but I hope I’m wrong.

Matt Yglesias of Vox also seems pessimistic, but for the opposite reason.

He has a column criticizing Republicans for wanting to push their policies by using “magic math” and he specifically seeks to debunk the notion - sometimes referred to as dynamic scoring or the Laffer Curve - that changes in tax policy may lead to changes in economic performance that affect economic performance.

He asks nine questions and then provides his version of the right answers. Let’s analyze those answers and see which of his points have merit and which ones fall flat.

But even before we get to his first question, I can’t resist pointing out that he calls dynamic scoring “an accounting gimmick from the 1970s” in his introduction. That is somewhat odd since the JCT and CBO were both completely controlled by Democrats at the time and there was zero effort to do anything other than static scoring.

I suppose Yglesias actually means that dynamic scoring first became an issue in the 1970s as Ronald Reagan (along with Jack Kemp and a few other lawmakers) began to argue that lower marginal tax rates would generate some revenue feedback because of improved incentives to work, save, and invest.

Now let’s look at his nine questions and see if we can debunk his debunking:
