Harvard and Yale alumni held a protest for fossil fuel divestment on the field at half-time at the annual Harvard-Yale game.

The Bolivian coup government accuses Morales of "sedition" and terrorism, based on an audio recording calling for protest strikes.

Protests are not terrorism, and even less is advocating protests terrorism. The use of the term "sedition" proves the injustice of the charges, since it simply means "criticizing the government," and a government which makes that a crime is unfit to rule.

Stiglitz: It's time to retire metrics like GDP. They don't measure everything that matters.

I propose three numbers to measure the overall health of the economy:

• What fraction of the cost of basic needs can some with a 20th percentile income have?
• What fraction of the cost of basic needs can someone with no income have for basic needs?
• What is the most a person with a 20th percentile income or less ever has to pay in order to access medical treatment?

In Iran, Iraq and Lebanon, people are protesting against the power of the government of Iran. Too bad that many of them are protesting to demand subsidized fossil fuels. That's exactly the thing to kill billions of people, given time.

The article errs in equating Iranian influence with Shi'ite power. The Shi'ites are the majority in Iraq, by far, and they will surely continue to be the dominant group in Iraq whether Iran is involved or not. The crucial question is whether they will admit individual Sunnis on a basis of equality, or crush them to the point that they rebel yet again.

All the avenues of research can't reduce the greenhouse footprint of aviation if people keep flying more. We need global taxes on flying, designed to discourage it.

With enough investment, we could also build high-speed trains as China has done. They could replace most air travel, and the remainder we could perhaps live with.
