Post Carbon Fellow Richard Heinberg was quoted on the dangers of geoengineering in this article in the San Jose Mercury News.

From the article:

“Research into geoengineering is a distraction from the hard work of reducing carbon emissions,” said Richard Heinberg of the Santa Rosa-based Post Carbon Institute.

“If something goes wrong, we may not be able to undo or control the damage,” said Heinberg, who is particularly opposed to efforts to block sunlight. “The metaphor ‘playing with fire’ hardly begins to communicate the level of risk we are talking about.”
