Health-Care Costs and Climate Change

By James Kwak

That’s the average global temperature from 1998 through 2008, according to NASA. This, of course, is what enabled George Will to write, in 2009, “according to the U.N. World Meteorological Organization, there has been no recorded global warming for more than a decade.”

Of course, George Will is just a run-of-the-mill climate change denier with a gift for mis-using statistics. In this case, he was probably citing a World Meteorological Organization study that said, “The long-term upward trend of global warming, mostly driven by greenhouse gas emissions, is continuing. . . . The decade from 1998 to 2007 has been the warmest on record.” And here’s the long-term picture, also from NASA:

You all know this, so why am I bringing it up?

Well, look at this, from J. D. Kleinke of AEI in The Wall Street Journal:

Those are annual percentage changes in nominal terms, so his point is that annual increases are going down. But what does the long term look like?

Bad Data

By James Kwak

To make a vast generalization, we live in a society where quantitative data are becoming more and more important. Some of this is because of the vast increase in the availability of data, which is itself largely due to computers. Some is because of the vast increase in the capacity to process data, which is also largely due to computers. Think about Hans Rosling’s TED Talks, or the rise of sabermetrics (the “Moneyball” phenomenon) not only in baseball but in many other sports, or the importance of standardized testing scores in K-12 education, or Karl Rove’s usage of data mining to identify likely supporters, or the FiveThirtyEight revolution in electoral forecasting, or the quantification of the financial markets, or zillions of other examples. I believe one of my professors has written a book about this phenomenon.

But this comes with a problem. The problem is that we do not currently collect and scrub good enough data to support this recent fascination with numbers, and on top of that our brains are not wired to understand data. And if you have a lot riding on bad data that is poorly understood, then people will distort the data or find other ways to game the system to their advantage.

Readers of this blog will all be familiar with the phenomenon of rating subprime mortgage-backed securities and their structured offspring using data exclusively from a period of rising house prices — because those were the only data that were available. But the same issue crops up in many different stories covering different aspects of society.

The Economist Backs Cantwell-Collins

Which, attentive readers know, is the climate change bill that auctions almost all emission allocations starting on day one, and refunds most of the proceeds to households. Here’s the Economist story. (Technically, it’s just the columnist “Lexington,” but the Economist has a consistency voice and position unlike any other news publication.) Here’s an excerpt:

“Of all the bills that would put a price on carbon, cap-and-dividend seems the most promising. . . . The most attractive thing about the bill is that it is honest. To discourage the use of dirty energy, it says, it has to be more expensive. To make up for that, here’s a thousand bucks.

“This challenges the conventional wisdom in Washington, DC, that the only way to pass a global-warming bill is to disguise what’s in it. Leading Democrats try to sell cap-and-trade as a way to create jobs and wean America from its addiction to foreign oil.”

Another Path to Cap-and-Trade

There’s been a lot of talk about California’s budget crisis and its dysfunctional political system–a wound that was entirely self-inflicted by the anti-tax brigade, which made it possible for one-third of one house of the legislature to block any increase in taxes. (See Ezra Klein for more.) But there’s another area where California is putting Washington to shame: climate change.

The Economic and Allocation Advisory Committee to the California Air Resources Board recently released its recommendations for how emission permits under the state’s cap-and-trade system should be allocated (summary here). The basic principles are that most of the allocations should be auctioned off, and about three-quarters of the proceeds should be given back to households in the form of tax cuts or dividend checks, allowing families to cope with any increases in energy prices that result from emissions caps. This, of course, is a far cry from Waxman-Markey, which starts off by giving most allocations to polluting industries, but is closer to the bill introduced by Maria Cantwell and Susan Collins in the Senate.

The difference seems to be that in California, the Global Warming Solutions Act of 2006 mandated the creation of a cap-and-trade system (to get California to 1990 emissions levels by 2020) and handed the implementation details to the California Air Resources Board, which commissioned a panel of economists, public policy people, and businessmen to work out the details. (The Board is not bound to accept their recommendation, however.) So this is a contrast between letting regulators set rules and having Congressmen set rules. (In our current Congress, the latter gives coal-state Democrats an effective veto, since the Republicans will not provide significant votes to any Obama administration proposal.) In other contexts I’ve argued that regulators should not have too much discretion, but here it may turn out to be a better approach.

New Deal for U.S. Climate Policy?

This guest post was submitted by James K. Boyce, an economist at the University of Massachusetts, Amherst. He has been a proponent of a “cap-and-dividend” policy to curb global warming while protecting the incomes of American families.

Last Friday, Senators Maria Cantwell (D-WA) and Susan Collins (R-ME) unveiled the CLEAR (Carbon Limits and Energy for America’s Renewal) Act, which could break the impasse in the debate over U.S. policy on climate change (McClatchy coverage is here.)

CLEAR has won a favorable reception from a broad swath of the political spectrum, ranging from ExxonMobil to Friends of the Earth. The scroll of supportive statements on Cantwell’s website includes praise from the AARP, the American Enterprise Institute, former U.S. Labor Secretary Robert Reich, Alaska’s Republican Senator Lisa Murkowski, and MoveOn.org.

Speculators ‘R’ Us: The G8 And Energy Prices

The G8 summit was obviously disappointing, even for those with low expectations. Usually, the substance is lacking but the public relations are well managed. This year even the messaging was messed up – they said some new things on climate change but not what we were told they could say, the food aid/development package was lamer than advertized, etc. So the whole thing looks like an expensive flop.

But actually it was much worse. Continue reading “Speculators ‘R’ Us: The G8 And Energy Prices” →
