Which Cities To Save From The Changing Climate

2 minutes

After several years of brutal flooding and hurricanes in the U.S., a distressing debate is emerging: if there is not enough money available to protect every coastal community from the effects of global warming, how do we decide which ones to save first.

Recent research looked at the costs involved in providing basic

storm-surge protection in the form of sea walls for all coastal cities with

more than 25,000 residents. That number

was $42 billion. Expanding the list to

include communities smaller than 25,000 people would increase that cost to more

than $400 billion. Realistically, that is

just not going to happen.

This particular study only looked at sea walls and no other methods

for minimizing flood risk, such as moving homes and businesses away from the

most flood-prone areas. It also didn’t

look at additional and costlier actions that will be required even with sea

walls, such as revamping sewers, storm water, and drinking water

infrastructure.

The facts are that many cities, especially small ones, will not be

able to meet the costs facing them.

Those that can’t will depend on federal funding. But even optimistically large proposals for

federal infrastructure spending are likely to fall far short of the vast

need. Ultimately, the money will end up

being spent where it can do the most good – even if it means that some places

are left out.

But what criteria will be used to direct the money? Economic value? Historic significance? Population?

Political influence?

This is a looming and massive issue whose chief obstacle may be that many officials refuse to acknowledge that it is happening. This is the next wave of climate denial – denying the costs that we are all facing.
