A report that argues global warming is a greater threat to world security than terrorism and predicts a warming future where "disruption and conflict will be endemic features of life," may sound like it came from a radical environmental group - but it didn't. Unless you consider the Pentagon a radical environmental group. The report, submitted last fall, but only recently released to the media, looked specifically at what would happen if the world's climate were to abruptly shift, rather than change at a constant pace, as most people naturally assume it would do.
