Less than two months after President Trump said he did not believe a federal report outlining the existential threat of man-made climate change, the Department of Defense has released its own report on how to manage the “effects of a changing climate.” As part of the defense spending bill for fiscal year 2018, the Pentagon was asked to create “a list of the ten most vulnerable military installations within each service” in addition to “combatant commander requirements resulting from climate change over the next 20 years.” The 22-page report begins with 11 words that contradict the commander-in-chief’s description of climate change as a “very expensive” hoax. It states, “The effects of a changing climate are a national security issue.” Those lines comprise “the strongest part of the report,” retired naval officer David Titley, who once headed the Navy’s Task Force Climate Change, tells Mother Jones in an email.
