Federal climate report: US energy, transportation sectors not prepared for warming

The U.S. energy and transportation sectors are unprepared for the impacts of climate change they are helping stoke, according to a new federal report that warns of "longer and more frequent power interruptions."

U.S. infrastructure is threatened by higher temperatures, stronger storms, increased flooding and longer, more intense droughts, according to the Fourth National Climate Assessment. While locational effects differ, "all regions will be affected by climate change," the authors conclude.

The assessment is the first federal climate change report written wholly under the Trump administration and its release on Black Friday was widely viewed as a tactic to limit its circulation. Experts say humans have about a decade to prevent the most catastrophic impacts of climate change and the U.S. is behind the necessary pace of emissions reductionsto do so.
