More importantly, Kelly is tightening control over the information that makes it to the president’s desk, Cheney said. Trump, who has praised Kelly’s leadership at the Department of Homeland Security and considers him a “tough guy,” may be more inclined to consider the challenges posed by climate change through the lens of national security.

Under Kelly, Southcom “played a major role in the rollout of the climate change adaptation roadmap,” said John Conger, who served as deputy undersecretary in the Pentagon comptroller’s office and assistant secretary of defense for energy, installations and environment under President Barack Obama.

At Southcom, Kelly worked to mitigate security crises caused by extreme weather patterns in Central and South America and the Caribbean. His annual overviews argued that humanitarian assistance for natural disasters was crucial to stabilize the region, and he noted that mass migrations and transnational organized crime were often tied to these natural disasters.

“You can’t operate in that region without being aware of how vulnerable these countries are and how climate change is affecting them,” said Sherri Goodman, who, under President Bill Clinton, became the Pentagon’s first deputy undersecretary of defense for environmental security. “Southcom (under Kelly) had been engaged in bolstering their security, because when they are threatened by rising sea levels and extreme weather it’s harder to defend from other threats like narcotrafficking and migration flows.”

U.S. military installations themselves are imperiled. Scientists estimate that rising sea levels threaten at least 128 U.S. military bases and installations, nine of which are major hubs for the U.S. Navy. Crucial waterfront installations are facing hundreds of floods a year, and some could be mostly submerged by 2100, according to a report from the Union of Concerned Scientists.

In June, Trump announced that he would withdraw the United States from the Paris climate accord, a move reportedly pushed by White House strategist Steve Bannon. Trump’s pick to lead the Environmental Protection Agency, Scott Pruitt, has expressed skepticism about global warming and said during his confirmation hearings that it had leveled off, an assertion refuted by scientists.

But as chief of staff, Kelly, at a minimum, is expected to ensure the president hears from all sides on this issue and others.

“Kelly is going to make sure that the voices that need to be heard are heard,” said Andrew Holland, director of studies and senior fellow for energy and climate at the nonpartisan policy organization American Security Project.

And his efforts on this topic may have more success than the much-publicized attempts of the president’s daughter, which included sit-downs with Al Gore and Leonardo DiCaprio and enlisting Apple’s Tim Cook to speak to her father. Ivanka Trump made climate change one of her signature issues, but her approach seemed to backfire.

“The military’s view is ‘who cares if there is a scientific debate, what’s happening now is real…and we still have to plan for it,’” said Holland.
