Infrastructure Matters

The good news is that 2018 wasn’t the hottest year on record, only the fourth hottest. The bad news is that the first, second, and third were 2015, 2016, and 2017. One record year doesn’t mean much as the average temperature of the planet is a somewhat “noisy” signal. But the trend is obvious and can’t be denied. How about this: 17 of the 18 hottest years on record have occurred since the year 2000.

This trend could be overlooked if one only looked at a particular locale like one state or even one country, but these statistics are based on the global mean temperature, measured by several different agencies, using differing techniques.

A proxy for the global temperature, isotopic analysis of ice cores at the poles can take us even further back in time, even past several glacial/interglacial cycles. It is hotter now than ever. The planet is warming overall and that is forcing other changes to the climate besides being simply hotter.

One of the more serious impacts which we are beginning to see already is an increase in the severity of weather phenomena. More intense hurricanes, heavier rainfall episodes, and more extended droughts can all be attributed to climate change.

The changes are a real existential threat to society. Our infrastructure must be remade to accommodate climate change. At the same time, we need to takes the steps necessary to slow planetary warming by reducing and ultimately abandoning the use of fossil fuels.

The text of the state of the union speech contained some mention of the need for attention to infrastructure. “Both parties should be able to unite for a great rebuilding of America’s crumbling infrastructure,” Trump told the assembled government leaders. “I know that Congress is eager to pass an infrastructure bill, and I am eager to work … on legislation to deliver new and important infrastructure investment.”

What wasn’t heard in the speech was any mention of climate change. In fact, climate change has been off the radar for the last three state of the union speeches. Simply replacing an old interstate highway bridge with a new one will not prepare us for the future. The bridges of the future will have to be higher to protect from increased flooding and built stronger to protect from hurricanes, tornadoes, or other storm events.

Coastal cities must plan for more flooding and more saltwater intrusion into their water systems. Power systems must not just be replaced but must be made more robust. It will be necessary to bury our electric transmission and distribution lines to protect them from untoward weather events.

An event, not out of the question, would be another record flood like the 1927 flood of the lower Mississippi River. An area, 27,000 square miles was flooded to a depth of 30 feet or more in Arkansas, Mississippi, and Louisiana. In today’s dollars that would be a several trillion dollar damage event.

Here in Arkansas, Governor Hutchinson is floating legislation to provide 300 million dollars annually for transportation infrastructure via a combination of sales and fuel taxes. Also planned is an increase in the registration fees for plug-in hybrid and fully electric cars such as the Chevrolet Bolt and the Tesla line. This is particularly wrong-headed as they are a solution to global warming. We should be promoting these vehicles, not punishing their use. The Governor’s plan is a business as usual infrastructure fix without any vision for the future and actually punishes actions needed for the future.
