President Joe Biden rejoined the controversial Paris Climate Accord, which punishes the use of fossil fuels such as oil, by signing an executive order during his first day in the White House on Jan. 20.

Biden additionally ordered a halt to the construction of the Keystone XL pipeline on the same day, to the economic detriment of the United States and Canada.

Former President Donald Trump, announced the withdrawal of the United States from these agreements in 2017 because they damaged the country’s economy and they are based on theories about climate change, strongly scientifically controversial

“Compliance with the terms of the Paris accord and the onerous energy restrictions it has placed on the United States could cost America as much as 2.7 million lost jobs by 2025 according to the National Economic Research Associates,” President Trump explained in announcing his withdrawal from those treaties. 

He added, “This includes 440,000 fewer manufacturing jobs—not what we need—believe me, this is not what we need—including automobile jobs, and the further decimation of vital American industries on which countless communities rely.  They rely for so much, and we would be giving them so little.”

“Russia and Venezuela will be thrilled to know their market share will increase thanks to the Biden Administration’s fumble,” wrote author Daniel Turner, noting the international strategic implications of that decision. 

Likewise, the premier of the province of Alberta, Canada, Jason Kenney, expressing annoyance that Biden did not consult with Canada before acting, estimates that the province stands to lose about $1 billion if the project is canceled.

“If the U.S. government refuses to open the door to a constructive and respectful dialogue about these issues, then it is clear that the government of Canada must impose meaningful trade and economic sanctions in response to defend our country’s economic interests,” Kennedy warned, according to local media outlet City News.

Part of Keystone XL has been built, but is not operational. The 1,210-mile pipeline would transport 830,000 barrels per day of crude oil from Hardisty (Alberta) to Steele City (Nebraska). 

It would then go to the company’s existing facilities to reach the U.S. Gulf Coast, one of the world’s largest oil refining centers.

Along with these executive orders Biden signed a dozen more, basically dedicated to wiping out the Trump administration’s accomplishments, denying Americans the benefits gained from them.
