Times were different when Line 5 was stretched underwater across the five miles of the Straits of Mackinac in 1953. The project was barely a blip in the news. People were hungry for new sources of energy to fuel their cars and homes. The pipeline existed for decades in a blissful state of anonymity.

Line 5, though, is no longer anonymous.

Over the last decade, most of the concern and criticism of Line 5 has been centered on the aging pipeline’s frailties, worry over its owner’s track record for pipeline safety, and a fear over the threat that the now very old infrastructure poses to the Great Lakes.

As Patrick Sullivan writes in this week's Northern Express - sister publication of The Ticker - there’s no question that a large-scale failure of Line 5 could be devastating to the lakes, but even as the line has been shut down over engineering concerns in recent weeks, some advocacy groups who oppose the pipeline have decided to add a new argument to the case that it should be removed: The fossil fuel carried by the line represents a significant potential to accelerate climate change, just as the people of this state have begun to recognize the consequences of climate failure, events like severe storms, flooding, and extreme heat.
