Dr. John Crusius, a research chemist at the U.S. Geological Survey (USGS), was denied approval to publish a research paper on natural solutions to climate change by agency officials. After several months of review, Dr. Crusius was told that he could only publish the paper in his personal capacity, and must not disclose his government affiliation in the paper. Dr. Crusius alleges that he was targeted because his work focuses on climate change. He told the New York Times: "There is no doubt in my mind that my paper was denied government approval because it had to do with efforts to mitigate climate change. If I were a seismologist and had written an analogous paper about reducing seismic risk, I’m sure the paper would have sailed through.”
