James Hansen, head of NASAs Goddard Institute for Space Studies, was arrested while protesting mountaintop removal coal mining in West Virginia. Hansen has been one of the most prominent scientists giving warning about the seriousness of climate change.
The problem of climate change is certainly serious enough to warrant civil disobedience, as recommended by Al Gore. Hopefully, such actions can help to draw attention to the myriad harms associated with coal mining and use. Increasingly, it makes sense to see coal as a densely packed form of carbon dioxide, already helpfully located underground, rather than a fuel we should be using.
