A major climate change report  Friday by over a dozen U.S. federal agencies outlines the potential for significant economic and environmental damages in the coming years. The report included a chapter on the potential for impacts on roads, bridges and other infrastructure.

Paul Chinowsky, a co-author of that chapter, is the director of ŷ���ڱ���Ƶ Boulder's Program in Environmental Design and a professor in the . His research focuses on costs, adaptations and infrastructure impacts related to climate change.

As part of the release of the report, Dr. Chinowsky was in the New York Times this weekend:

Nevertheless, despite the satisfaction at seeing their scientific work made public, many of the authors expressed disappointment that Mr. Trump’s strategy appears to be to ignore the findings and move forward with plans to undo climate change policies.

“It’s incredibly frustrating,” said Paul Chinowsky, a professor of civil engineering at the University of ŷ���ڱ���Ƶ, Boulder, and a co-author of the report’s That chapter concludes that more extreme storms, flooding and heat waves, along with rising sea levels, will damage the nation’s roadways, leading to dangerous infrastructure collapses and up to $21 billion in damage by the century’s end.

“I’m watching these arguments between politicians and scientists, but I’m on the ground with public works officials who say that argument’s irrelevant,” Mr. Chinowsky said. “People are going to get hurt and die if we don’t change the policy.”
