The New York Times (NYT) recently published an article titled "Climate Change Can Cause Bridges to 'Fall Apart Like Tinkertoys,' Experts Say," written by Coral Davenport. Multiple lines of evidence and examples not only refute this claim as false but expose the sheer absurdity of the claim.

These sorts of absurdly false claims have been tried before, for instance, when the I-35W bridge collapsed in Minneapolis, MN in 2007. An article in 2007 by Noel Sheppard at NewsBusters exposed the claim as false:

A former member of the Clinton administration, and current Senior Fellow at the virtual Clinton think tank the Center for American Progress, claimed Monday that global warming might have played a factor in the collapse of the I-35W bridge in Minneapolis last week.

I kid you not.

Writing at Climate Progress, the global warming blog of CAP, Joseph Romm - who served as Acting Assistant Secretary of the U.S. Department of Energy in 1997 and as Principal Deputy Assistant Secretary from 1995 though 1998 - stated in a piece amazingly entitled "Did Climate Change Contribute To The Minneapolis Bridge Collapse?"

Unsurprisingly, the actual cause had nothing to do with climate change at all but rather an engineering failure that used undersized gusset plates that were too thin for the load of the bridge:

The investigation revealed that photos from a June 2003 inspection of the bridge showed gusset-plate bowing. On November 13, 2008, the NTSB released the findings of its investigation. The primary cause of the collapse was the undersized gusset plates, at 0.5 inches (13 mm) thick. Contributing to that design or construction error was the fact that 2 inches (51 mm) of concrete had been added to the road surface over the years, increasing the static load by 20%. Another factor was the extraordinary weight of construction equipment and material resting on the bridge just above its weakest point at the time of the collapse. That load was estimated at 578,000 pounds (262 tonnes), consisting of sand, water, and vehicles.

So, human error and extra weight, not climate change, was determined to be the cause of the bridge's failure.

Fast forward to the present. The NYT's article makes similar claims:

Bridges designed and built decades ago with materials not intended to withstand sharp temperature swings are now rapidly swelling and contracting, leaving them weakened.

"It's getting so hot that the pieces that hold the concrete and steel, those bridges can literally fall apart like Tinkertoys," Dr. Chinowsky said.

As temperatures reached the hottest in recorded history this year, much of the nation's infrastructure, from highways to runways, has suffered. But bridges face particular risks.

Really? The bridges in question weren't engineered to handle daily temperature swings? A natural event that happens daily across seasons? That sounds like poor planning. Besides the absurdity of that claim, there are two further contradictory points to consider.

First, in the United States, we've seen far worse sustained heatwaves before, such as in the 1930s when the July 1936 heatwave hit America's Midwest, where some places experienced up to 14 days of above 100°F temperatures. This is evidenced by the graph in Figure 1, provided by the U.S. Environmental Protection Agency.
