On the Bright Side: Three Full Decades of CO2-Induced Vegetative Greening in China

Here we introduce a new feature from the Center for the Study of Science, “On the Bright Side.” OBS will highlight the beneficial impacts of human activities on the state of our world, including improvements to human health and welfare, as well as the natural environment. Our emphasis will typically focus on the oft-neglected positive externalities of carbon dioxide emissions and associated climate change. Far too often, the media, environmental organizations, governmental panels and policymakers concentrate their efforts on the putative negative impacts of potential CO2-induced global warming. We hope to counter that pessimism with a heavy dose of positive reporting on the considerable good humans are doing for themselves and for the planet.

According to Piao et al. (2015), the reliable detection and attribution of changes in vegetation growth are essential prerequisites for “the development of successful strategies for the sustainable management of ecosystems.” And indeed they are, especially in today’s world in which so many scientists and policy makers are concerned with what to do (or not do) about the potential impacts of CO2-induced climate change. However, detecting vegetative change, let alone determining its cause, can be an extraordinarily difficult task to accomplish. Nevertheless, that is exactly what Piao et al. set out to do in their recent study.

More specifically, the team of sixteen Chinese, Australian and American researchers set out to investigate trends in vegetational change across China over the past three decades (1982-2009), quantifying the contributions from different factors including (1) climate change, (2) rising atmospheric CO2 concentrations, (3) nitrogen deposition and (4) afforestation. To do so, they used three different satellite-derived Leaf Area Index (LAI) datasets (GLOBMAP, GLASS, and GIMMIS) to detect spatial and temporal changes in vegetation during the growing season (GS, defined as April to October), and five process-based ecosystem models (CABLE, CLM4, ORCHIDEE, LPJ and VEGAS) to determine the attribution.

Poll: 51% Say Business Owners Should Serve Same-Sex Couples, but 59% Say Wedding Businesses Should Be Allowed to Decline

A recent AP/GfK poll finds a slim majority (51%) of Americans say businesses with religious objections should be required to serve same-sex couples. Forty-six percent (46%) say these business owners should be allowed to refuse service. However, for business owners specifically offering wedding-related services, Americans say these particular businesses “should be allowed to refuse service” by a margin of 59% to 39%. 

These results correspond with the nuanced argument Cato scholar Roger Pilon recently made in the Wall Street Journal. Pilon explains that businesses open to the public ought to serve everyone; however, business owners with religious objections (who are not a monopoly) should not be forced to participate in the creative act of planning and participating in the wedding of a same-sex couple. Referring to two couples who recently were heavily fined for declining to provide services for same-sex weddings, he writes:

“Because they represent their businesses as open to the public, the Kleins and Giffords shouldn’t be able to deny entrance and normal service to gay customers… But it is a step further—and an important one—to force religious business owners to participate in a same-sex wedding, to force them to engage in the creative act of planning the event, baking a special-order cake for it, photographing it, and so on.”

Americans seem inclined to support this nuanced view that businesses should serve all customers regardless of sexual orientation, religion, race, gender, income, national origin, etc.—but that wedding-related businesses requiring owners’ direct participation in the wedding should not be forced to provide service against the owners’ religious beliefs.

Keeping Their Promises

In blogs over the last several months, I have revisited the fiscal records of the eight Republican presidential candidates who have gubernatorial experience. As the 2016 race heats up, the candidates will begin making many promises on tax and spending issues, but will we be able to believe them?

The records show that some governors worked hard to limit the size and scope of government. Others grew government with more spending and higher taxes. The candidates fit into three categories: the “A’s,” the falling grades, and the consistent “B’s”.

Three of the former governors earned at least one “A” during their tenure: George Pataki of New York, Jeb Bush of Florida, and Bobby Jindal of Louisiana. Pataki earned high marks for slashing state spending by $2 billion and cutting the personal income tax. Bush passed a billion dollar property tax cut coupled with a large business tax cut. Jindal dramatically cut spending. Spending is down 9 percent in Louisiana since fiscal year 2009.

No Markets, Then No Water. California’s Avoidable Crisis

This is what happens in a world without markets for water, as Eli Saslow reports in the Washington Post:

Their two peach trees had turned brittle in the heat, their neighborhood pond had vanished into cracked dirt and now their stainless-steel faucet was spitting out hot air. “That’s it. We’re dry,” Miguel Gamboa said during the second week of July, and so he went off to look for water….

For a few days now, they had been without running water in the fifth year of a California drought that had finally come to them. First it had devastated the orchards where Gamboa and his wife had once picked grapes. Then it drained the rivers where they had fished and the shallow wells in rural migrant communities. All the while, Gamboa and his wife had donated a little of their hourly earnings to relief efforts in the San Joaquin Valley and offered to share their own water supply with friends who had run out, not imagining the worst consequences of a drought could reach them here, down the road from a Starbucks, in a remodeled house surrounded by gurgling birdbaths and towering oaks.

The article reads like science fiction. And it’s so tragic, because markets could go a long way toward allocating California’s water to its highest-valued uses, as Peter Van Doren and Gary Libecap discussed recently. More Cato studies on water markets here.

Kasich’s Fiscal Record

John Kasich, the Governor of Ohio, makes his presidential announcement today. He becomes the 16th person to join the Republican field and the 8th current or former governor.

Kasich is a fiscal policy expert. He has made a federal Balanced Budget Amendment a key talking point in his speeches and appearances so far, and was known for being a budget cutter while in Congress. His record in Ohio tells a very different story. Spending has risen rapidly  during Kasich’s tenure in Columbus.

Data from the National Association of State Budget Officers illustrates the rapid growth general fund spending. From fiscal year 2012, Kasich’s first full fiscal year, to fiscal year 2015, general fund spending increased in Ohio by 18 percent. Nationally, state general fund spending increased by 12 percent during that period. Kasich’s proposed budget for fiscal year 2016 increased spending further. It included a year-over-year increase of 11 percent. The average governor proposed a spending increase of 3 percent from fiscal year 2015 to fiscal year 2016.

Finding Rights in the Constitution

Last month, when Justice Anthony Kennedy found that same-sex marriage was a “fundamental right,” did he and the four other justices for whom he wrote find a “new” constitutional right? Or is it rather, as some of us have long argued, that the Constitution protected that right for nearly a century and a half, like the right to same-sex sodomy (Lawrence v. Texas), to sell and use contraceptives (Griswold v. Connecticut), to educate one’s child in a parochial school (Pierce v. Society of Sisters), and, dare I say, to freedom of contract in employment (Lochner v. New York)?

I address those questions in a piece in today’s National Law Journal, defending Kennedy’s conclusion in Obergefell v. Hodges but taking exception to his reasoning. The fundamental right to same-sex marriage rests mainly, he argued, on the liberty interest that is protected under the Fourteenth Amendment’s Due Process Clause. Not so, said Justice Clarence Thomas in his dissent. Drawing extensively on John Locke’s state-of-nature approach to political legitimacy, which the Founders and Framers drew on as well, Thomas argued that the Obergefell plaintiffs were not denied the right to marry. They were perfectly free to go to any willing clergyman who would marry them—and the state would not have interfered with their liberty to do so. What they wanted, he saw, was a state license, the state’s positive recognition of the marriage, and the legal benefits that go with the state’s recognition.

Kennedy’s conclusion as against the state, therefore, belongs properly not under the Fourteenth Amendment’s Due Process but under its Equal Protection Clause. The state denied same-sex couples the same benefits it granted opposite-sex couples and thus discriminated against them. Thus, the right to marry someone of the same sex may be a natural right that anyone would enjoy in the state of nature; but once we leave that state, if an actual state we’re in grants the privileges of marriage, the denial of those privileges is properly litigated against the state under the Equal Protection Clause. Unfortunately, Thomas never developed those points—nor could he have without coming out for same-sex marriage—nor did Kennedy’s brief and gauzy discussion of equal protection get to the heart of the matter either.

Funding Highways: States Can Do It

Congress faces a deadline at the end of July to extend federal highway funding. Policymakers are likely to cobble together a short-term fix for the funding gap in the Highway Trust Fund (HTF), rather than enacting a permanent solution.

Annual HTF spending is projected to be $53 billion and rising in coming years, while HTF revenues will be $40 billion. That leaves an annual funding gap of at least $13 billion. A good permanent fix would be to cut federal spending by $13 billion to match the revenues. State governments could fill the gap with their own funding, efficiency improvements, or privatization.

That straightforward decentralization solution is not popular with highway lobby groups, and it is usually not mentioned as an option by reporters. A recent Washington Post Wonkblog column is typical. It examined road quality and potholes in the states, and then concluded that more federal money was needed.

The Post published my letter in response to Wonkblog on Saturday:

The article noted that some states (such as California) have many car-damaging potholes, while others (such as Florida) have very few. It said that “we haven’t been putting enough money into the Highway Trust Fund.”

Actually, the data reveal that California ought to be learning lessons from Florida on how to spend existing funds more efficiently. The fact that some states have much better highways than others shows that states can solve their own highway problems — without the top-down federal actions suggested in the article.

Here are some of the details from the original Wonkblog story:

… 28 percent of the nation’s major roadways—interstates, freeways, and major arterial roadways in urban areas—are in “poor” condition.

[Other than D.C.] … the worst roads are in California where 51 percent of the highways are rated poor. Rhode Island, New Jersey and Michigan all have “poor” ratings of 40 percent or more. Dang.

And while everybody loves to make fun of Florida, the Sunshine State actually has the smallest percentage of bad roads in the nation—only 7 percent. Nevada, Missouri, Minnesota and Arkansas round out the top 5.

Note that Florida is a warm and sunny, while Minnesota is cold and snowy, yet they both have very good roads. Meanwhile, California is warm and sunny, while Michigan is cold and snowy, yet they both have very poor roads. Wonkblog correctly notes, “I might have expected weather and latitude to play a big role in road quality, but that doesn’t seem to be the case here.”

So far so good, but then Wonkblog jumps to his predetermined solution, and completely ignores the implication of the data he had just presented. He says, “One main reason why our roads are in such bad shape is that we haven’t been putting enough money into the Highway Trust Fund to keep up with infrastructure needs.”

According to Wonkblog’s own chart, only 10 percent of the roads in Minnesota are in “poor” condition, while 51 percent in California are poor. Thus, bad roads are clearly a state-level failing. Wonkblog immediately grabs for the magic wand of more federal funding, but he might have asked what it is that states like Minnesota are doing right with the existing funding.  

The other weird thing about Wonkblog’s conclusion is that he says, “we haven’t been putting enough money into” the HTF. But, of course, it is spending that might affect road quality, not the revenues “into” the fund. If you look at HTF spending, it has remained high in recent years because Congress has filled it with general fund revenues, as I chart here.

In sum, there are apparently dramatic differences in road quality between the states. That may stem from differences in state funding, state efficiency, and state competence, but seemingly not climate conditions. All the states have the ability by themselves to have high quality roads, but some states it appears have important road-investment lessons to learn from the others.
