The Trump administration axed climate change from its national security strategy, with huge implications for how America adapts to the threats of a warming world. But thatâs not the only way weâre seeing the environmental fallout of Trumpâs national security agenda.
Along our borders with Canada and Mexico, conservation and climate justice fights are getting tangled up with national security interests. To the south, Trumpâs proposed wall threatens dozens of endangered species, like the Mexican gray wolf. And in the north, Canadaâs purchase of the Trans Mountain Pipeline hinges in part on a U.S. assessment of national security threats.
The wall
The Department of Homeland Security essentially has a get-out-of-federal-law pass that allows them to ignore environmental regulations. In the case of the border wall, the department can move forward with construction without an environmental impact analysis and wonât be subject to following the Endangered Species Act or National Environmental Policy Act.
This capacity to be above the law has enormous impacts for the survival of species found along the U.S.-Mexico border. Leading scientists, including Paul Ehrlich and E.O. Wilson, published an article on the dangers in the journal BioScience last week. More than other 2,500 other scientists signed onto a call to action urging Homeland Security to follow federal law, evaluate the environmental impact of its border wall, and take action to mitigate the harm.

The wall would restrict the movement of communities and scientists working on conservation on both sides of the border, says lead author Rob Peters. Beyond the human angle, âany sort of barrier to the free movement of animals is a threat to their existence,â Peters says. âThe borderlands are not the empty wastelands that so many people think they are. Theyâre incredibly rich in biodiversity.â According to the report, the wall would impact up to 62 species listed as critically endangered, endangered, or vulnerable by the International Union for Conservation of Nature.
The pipeline
Meanwhile, up north, itâs now up to federal authorities, with Trump making the ultimate decision, to allow or veto Canadaâs purchase of Kinder Morganâs TransMountain Pipeline.
Kinder Morgan halted non-essential spending on the pipeline expansion this spring and was ready to drop the project completely. Thatâs when the Trudeau administration announced it was going to foot the bill to keep the flailing project alive.
So, why does that require Trumpâs approval? Canadaâs purchase of TransMountain includes the acquisition of an offshoot pipeline: the Puget Sound Pipeline, which moves oil from British Columbia to Washington state. As a result, the deal canât move forward without national security clearance from the U.S. Committee on Foreign Investments. Itâs also subject to review by the State Department, which issues presidential permits for cross-border liquid pipelines.
Normally, those procedures are pretty cut-and-dry. But under the Trump administration, experts say, anything goes. âOnce upon a time, there was a set of regulations that could tell you more or less what the considerations were. I donât think those are operative at all right now,â says Tom Sanzillo, director of finance at the Institute for Energy Economics and Financial Analysis. âI think whatever the president wants heâll do,â Sanzillo says.
In its 2017 National Security Strategy, the Trump administration mentions streamlining federal approval of pipelines as a good thing for Americans. But these are weird times; trade tensions and Trumpâs fighting words with Trudeau over the summer could make the U.S. president an unlikely trump card for those hoping the pipeline deal will die.
There are legitimate concerns about Canada owning a slice of American energy infrastructure, according to Clark Williams-Derry, director of energy finance at Seattle-based think tank Sightline Institute (Williams-Derry was also the webmaster for Grist back in 1999). âThis is the only case for a foreign government to outright own a U.S. pipeline. Itâs a little bit unsettling,â Williams-Derry says.
If Trump decides he doesnât want to Canada to have the Puget Sound Pipeline, it would deal a significant blow to the Kinder Morgan Deal. But both Williams-Derry and Sanzillo say that although it would further delay the Trans Mountain Pipeline expansion, it wouldnât altogether kill it. With $3.5 billion on the line, Kinder Morgan and Trudeauâs government could find a way to take the Puget Sound Pipeline out of the deal in order to bypass U.S. intervention on the purchase.
The looming threat
And if the pipeline expansion is successful and leads to significantly more crude oil pumping out of Albertaâs tar sands, thereâs another huge threat to consider: âClimate change is certainly a threat to national security,â says Williams-Derry. âIf a hostile foreign power said, âWeâre going to devastate Miami or weâre going to increase the chance of a major incident on the Gulf Coast,â we would say, âNo way. Absolutely not.ââ
And climate change is a concurrent threat for species at the border. The wall would hamper their efforts to adapt, especially in places like in the Southwest where animals may migrate to cope with drought. âWe canât say exactly how [climate change] is going to affect them,â says Rob Peters. âBut we sure as hell can say it ainât going to be good.â
