For this week’s deeper dive, a closer look at the Trump administration’s rollbacks on climate regulations.

In the past week, the Trump administration revoked a scientific finding that long has been the central basis for U.S. action to regulate greenhouse gas emissions and to fight climate change.

In 2009, a government declaration known as the “endangerment finding” determined that carbon dioxide and other greenhouse gases threaten public health and welfare. The Obama-era finding is the legal underpinning of nearly all climate regulations under the Clean Air Act for motor vehicles, power plants and other pollution sources that are heating the planet.

The Environmental Protection Agency rescinded this rule. The repeal eliminates all greenhouse gas emissions standards for cars and trucks and could unleash a broader undoing of climate regulations, experts say.

U.S. President Donald Trump called the endangerment finding “one of the greatest scams in history,” claiming falsely that it “had no basis in fact” or law.

Environmental groups said the plan would keep polluting, gas-burning cars and trucks on U.S. roads for years to come, threatening the health of millions of Americans, particularly children and the elderly.

But EPA Administrator Lee Zeldin, a former Republican congressman who was tapped by Trump to lead the agency last year, has criticized his predecessors in Democratic administrations, saying that they were “willing to bankrupt the country” in the name of tackling climate change.

John Rapley, contributing columnist for The Globe and Mail, wrote about the price of this move – and why it was a sure vote-winner.

Rapley notes that in Trump’s campaign, he offered something for everyone in reversing the climate initiatives of previous administrations: Fossil fuel companies got favourable policies and consumers were promised cheap gas and cars.

“All told, in his determination to deliver immediate benefits to his followers by scrapping environmental initiatives, Mr. Trump is creating added costs for them. This could turn into a major political headache for him.”

While his climate denialism is so far benefiting his rich backers, his mass base hasn’t been seeing the savings.

“To paraphrase Trotsky, we may not be interested in climate change, but climate change won’t allow us to escape its net. If we don’t pay the price of arresting it now, we’ll get the bill in due course – and the sticker shock could end political careers.”

So, Rapley asks: What will finally bring down Donald Trump? Maybe it’s climate change.
