Military Defies Trump's Orders: Pentagon Plans for Addressing Climate Change


September 16, 2017

Unlike his White House boss, Defense Sec. Jim Mattis does not believe that climate change is a "hoax" invented by the Chinese. The Defense Department has warned for years that climate change is a national security threat and, despite President Trump's orders, the agency continues to take steps to help the military prepare for the impacts of a warming planet. In an unprecedented act of defiance, the Pentagon is continuing to prepare to deal with the effects of climate change -- even though Trump told them to stop.

Pentagon Moves Ahead with Obama-era
Climate Preparation Plan Despite Trump's Orders

(September 15, 2017) -- The Department of Defense (DoD) has warned for years that climate change is a national security threat and, despite President Trump's orders, the agency continues to take steps to help the military navigate and prepare for the impacts of a warming planet.

As Military Times reports, the Pentagon is plowing ahead with its 2014 "Climate Change Adaptation Roadmap" even though Trump issued an executive order in March seeking to reverse Obama-era federal climate and clean energy initiatives.

Under Obama's orders, the Defense Department issued directive 4715.21 in January 2016 to implement the roadmap, which "lays out reasonable adaptation and mitigation actions to ensure or at least bolster our national security against measured and measurable climate change events, whatever the causes, or the duration, of the observed events," as retired Navy Adm. Frank Bowman said.

But now -- thanks to Trump–the agency is reviewing directive 4715.21 "to determine if it should be suspended, revised, or rescinded," Pentagon spokesman Lt. Cmdr. Patrick Evans told the publication.

However, the department is still preparing for the effects of climate change even though Trump told them to stop. For instance, as Military Times reports, the Naval Facilities Engineering Command (NAVFAC) Mid-Atlantic has been taking steps to protect the Hampton Roads base in Virginia -- home to 60 Navy ships, hundreds of fix-wing and rotary aircraft and more than 83,000 active duty personnel.

The 2014 climate roadmap, which Trump invalidated, stipulated that the assets were protected from a "projected sea-level rise of 1.5 feet over the next 20 to 50 years."

"I can't talk the science, but I can tell you what we've done," Todd Lyman, NAVFAC Mid-Atlantic spokesman, explained. "For many years, NAVFAC has been replacing any single-deck pier with double-deck piers. We've also built structures here at a higher elevation than code requires in an effort to improve stormwater management. The goal is for us to continue our mission, maintain resilience."

According to Military Times:
The DoD has found space to maneuver by separating the argument of climate change from the threats that more extreme sea states, wind and flooding can generate. Essentially, the DoD is moving forward by leaving the semantics of climate change to others.

"As Secretary Mattis has said, the department evaluates all potential threats that impact mission readiness, personnel health and installation resilience, then uses that information to assess impacts and identify responses," Evans said. "The effect of a changing climate is one of a variety of threats and risks, but it's not a mission of the Department of Defense."


It looks like the Pentagon's strategy is just to avoid using language related to climate change and instead focus on how the military can fortify its installations against extreme weather events and natural disasters (which, like Hurricanes Harvey and Irma, are linked to climate change.)

Unlike his White House boss, Defense Sec. Jim Mattis does not believe that climate change is a "hoax" invented by the Chinese.

"Climate change is impacting stability in areas of the world where our troops are operating today," Mattis wrote in March. "It is appropriate for the Combatant Commands to incorporate drivers of instability that impact the security environment in their areas into their planning."



Intensity of Hurricane Harvey's
Devastation Linked to Warming

Tropical storm Harvey is by any standard off the scale. Some parts of Texas have received in just over a week the rainfall they would normally expect in an entire year, and the storm is described as generating as much rain as would normally be seen only once in more than 1,000 years.

Exceptional as it is, Harvey is not a direct consequence of climate change, in the judgment of one leading climate scientist, professor Stefan Rahmstorf, co-chair of Earth System Analysis at the Potsdam Institute for Climate Impact Research (PIK) in Germany.

However, Rahmstorf couples his clear rebuttal that the warming climate triggered Harvey with a significant qualification. The increased heat accumulating in the atmosphere, he said, has almost certainly intensified the storm's destructiveness, in line with other evidence suggesting a link between extreme weather and the human influence on the climate.

Extreme Rainfall
In a statement released by PIK, he said:
"Storm Harvey was not caused by climate change, yet its impacts—the storm surge and especially the extreme rainfall -- very likely worsened due to human-caused global warming.

Asking for a single cause of a specific weather event usually doesn't make sense, since there's always a number of factors at play. What can be said is whether and how climate change affects the character of some extreme events. Scientific findings from past decades offer some insights here.

A logical consequence of global warming is a global increase of extreme rainfall events -- in the case of Harvey, it is in fact the heavy rain and the resulting flooding which is probably the greatest threat.

The increase of extreme precipitation is due to the fact that warmer air can hold more water vapor.

A global increase of daily rainfall records is indeed seen in the rainfall observations, as has been shown in a PIK study. This trend will continue as long as we keep pushing up global temperatures by emitting greenhouse gases.

"More tentative, yet quite possibly also relevant, is a general slowdown of atmospheric summer circulation in the mid-latitudes. This is a consequence of the disproportionally strong warming in the Arctic. It can make weather systems move less and stay longer in a given location -- which can significantly enhance the impacts of rainfall extremes, just like we're sadly witnessing in Houston."


In what sounds like support for Rahmstorf's tentative suggestion, a BBC journalist reported on Tuesday, "The big problem with tropical storm Harvey is just how slow-moving it has become, with the centre of the storm just meandering around, allowing moisture to pile in continuously from the Gulf of Mexico, and that has fed torrential rain, which has affected the same areas for several days now."

Strongest Storms
Rahmstorf said that no change in the overall frequency of tropical storms was expected, and no significant change had been observed so far. But theory and models both suggest there was likely to be a change in the intensity of storms.

"The strongest tropical storms could become even stronger due to increasing sea surface temperatures, because this is where these storms get their energy from," he said. "That's the reason they develop only above water warmed to at least 26°C.

It is under debate whether observational data support the theoretical expectation of an increase in the strongest storms, since these are rare and the observational data series therefore need to be very long and homogeneous to be conclusive.

Rising seas are a clear result of global warming, causing ocean levels to increase by roughly 20cm since the late 19th century. Thermal expansion of sea water, melting mountain glaciers and mass loss in Greenland and Antarctica are the main contributors."


Tim Palmer, Royal Society research professor in climate physics at the University of Oxford, UK, said that perhaps the single most important question for attributing Harvey to climate change is whether such stationary hurricanes would become more commonplace in the future.

"This is a question about possible changes in circulation, and hence dynamics," he said. "There is still uncertainty about many aspects of the dynamics of climate change, and this will only be addressed by investment in climate models and the top-of-the-range supercomputers needed to run them.

"This is an area where UK scientists must continue to collaborate strongly with their colleagues in Europe."

Dave Reay, professor of carbon management at the University of Edinburgh's School of Geosciences, UK, said, "Flood defense plans based only on past events will become obsolete as our warming atmosphere delivers much more rain and much more often. President Trump may have withdrawn the U.S. from the Paris climate agreement, but he can't opt out of the laws of physics."

Other countries are also struggling with severe flooding. Reports from Bangladesh, for instance, said that by late August more than 100,000 people in flood-affected areas had sought refuge in emergency centers.
