Download: Harvard’s geoengineering failure, and extending the life of nuclear plants


In March 2017, at a small meeting in Washington, DC, two Harvard professors, David Keith and Frank Keutsch, developed a plan to carry out what would have been the first attempt at solar geoengineering in the stratosphere.

The basic principle behind solar geoengineering is that by spraying particles on Earth’s surface, humans can direct sunlight back into space to combat climate change. But critics say interventions that could change the global climate are too dangerous to study in the real world.

A single, small balloon experiment came to represent all of these fears—and, in the end, it was more than the researchers bargained for. Last month, ten years after the project was first planned, Harvard announced that the project had ended. So what went wrong? And what does that failure say about the freedom researchers have to investigate this sensitive issue? Read the full article.

Why is the life cycle of nuclear power plants increasing?

The average age of nuclear power generation worldwide is increasing. In the US, which has more reactors than any other country, the average is 42 years old. About 90% of the reactors in Europe have been around for 30 years or more.

Old rectors, especially small ones, have been closed in many groups due to financial problems, especially in areas with cheap electricity, such as cheap gas. But there may still be plenty of life left in old nuclear weapons.
