US hurricane rebuilding rules must adapt to ‘era of climate change’: expert

After an extreme weather event, such as Hurricane Ian which devastated parts of Florida last month, most Americans choose to rebuild rather than move to less hazardous areas.

But as climate change increases the frequency and scale of natural disasters, does US policy need to adapt?

Gavin Smith, a professor of environmental planning at the University of North Carolina, worked for several states following major hurricanes, including Katrina in Mississippi (2005) and Matthew in North Carolina (2016).

According to him, current reconstruction standards are not up to the challenges posed by climate change, but correcting them will require real “political will.”

Smith’s responses to AFP have been lightly edited and condensed for clarity.

Current reconstruction rules

Q: What are the rules for re-construction after a hurricane, and are they adapted to climate change?

A: Communities must comply with the local codes and standards in place in their jurisdiction before the storm struck.

In the US, we have the National Flood Insurance Program (NFIP), which has historically been subsidized by the federal government. 

For a community to join the program, it has to adopt certain flood risk reduction standards. They include building codes as well as land use plans.

Then, if a home is damaged in the storm more than 50 percent of their value, it must be built back to the most recent code and standards in place.

Our standard for flood is rebuilding largely back to the “100 year flood,” more accurately termed the one percent annual chance flood event. But in an era of climate change, that “100 year” flood is happening more and more often.

Most risk reduction codes and standards often reflect a climate of the past.

For example, we spent $14 billion rebuilding the levee system in New Orleans after hurricane Katrina. That levee system was built back to the “100 year flood.” 

So you could make the argument that in the era of climate change, that levee system is already out of date.

Political will

Q: What do you expect from government officials?

A: Disasters can present opportunities to rebuild communities safer.

What I’m suggesting is that if we’re going to spend hundreds of millions of dollars building these communities back, we need to require communities to adopt higher codes and standards. 

But that takes political will of both members of Congress and local elected officials.

These are really difficult trillion dollar questions.

You’ll also have builders and the private sector saying, “We should limit those kinds of regulations, as we need to quickly rebuild.”

It takes a lot of political will for a mayor or for a governor to say “No, we’ve got to do what’s right in the long run.:

Unfortunately, people don’t get elected by saying “I am going to require higher standards.”

That’s not a winning slogan. It takes political will to say, enough is enough, we need to adopt higher standards, it’s going to take time, cost more, and people may have to pay more to do it.

That said, we also need to make sure we include equity in processes adopted to develop those standards.

The shrimpers and the crabbers that live in a very modest house on the water, if we make them adopt higher standards, can they afford it?

Rules for resilience

Q: Concretely, what would be these better standards?

A: A really simple way to think about it is “where” and “how” you build in relation to natural hazards, including those exacerbated by climate change.

The “how” include elevating structures, more stringent standards for wind performance, like better roof shingles, hardening our infrastructure — communication systems, bridges, roads, levees… We can also do this by protecting natural systems like dunes and wetlands.

The “where” is what we would often refer to as land use planning.

Should we be putting a hospital, or a school, in an area subject to storm surge? Probably not. 

A community may choose to say, we’re not going to build a house within 200 meters of the beach. 

Or adopt a gradual disinvestment strategy in extremely risky areas (managed retreat). It’s very difficult to do politically, but it’s happening on a small scale.

Resilience is really about a series of protective measures or choices. It’s not just one. A levee, if that’s your only protection and it fails, to me that’s not resilience.

China calls for dialogue amid rising Iran-Israel conflict

The Chinese government emphasized on Monday the importance of “creating the conditions to return to the proper path of dialogue” between Iran and Israel, which have exchanged attacks in recent days resulting in more than 20 Israeli and over 220 Iranian deaths.

Chinese Foreign Ministry spokesperson Guo Jiakun expressed deep concern at a press conference over the Israeli attacks on Iran and the “sudden escalation” of the military conflict.

Guo called on all parties to “take immediate measures to ease tensions and prevent the region from descending into further turmoil,” stating that “force cannot bring lasting peace.”

“If the conflict between Israel and Iran continues to intensify or even expand, the countries of the Middle East will be the first to suffer the consequences,” he added, while noting that China “will continue to maintain communication with the relevant parties, promoting peace and dialogue.”

Chinese Foreign Minister Wang Yi spoke last Saturday with his Iranian and Israeli counterparts to condemn the Israeli airstrike on Iranian territory, which he described as a “violation of international law” with the potential to trigger “disastrous” consequences.

In both calls, Wang reiterated China’s rejection of the use of force, defended diplomacy as the only solution to the Iranian nuclear dispute, and offered China’s mediation to prevent further destabilization in the Middle East.

Suspect arrested in killing of Minnesota legislator and husband, governor Says

Minnesota Governor Tim Walz announced on Sunday the arrest of Vance Luther Boelter, 57, the main suspect in the killing of Democratic legislator Melissa Hortman and her husband in a Brooklyn Park suburb on Friday night.

Boelter, who also reportedly shot State Senator John Hoffman and his wife early Saturday morning, was apprehended in Sibley County following an intensive manhunt involving hundreds of law enforcement officers.

In a public statement, Governor Walz condemned Boelter’s “unthinkable actions,” which resulted in the death of a woman who “shaped the core of who we are as a state.”

“We cannot become numb to this. We are a deeply divided nation,” Walz said in a statement posted on his X account.

“We move forward not with hatred or violence, but with humility, grace, and civility,” he added.

Expressing solidarity with the victims’ families, Walz said the entire state of Minnesota is in mourning. He also thanked law enforcement for their bravery and professionalism: “They have saved lives,” he emphasized.

“As we heal, we will not let fear win,” Walz concluded. “We must honor Melissa by moving forward with understanding, service, and above all, humanity.”

Throughout Sunday, police and sheriff units searched a rural area in Minnesota for Vance Luther Boelter, a security company director and preacher who, according to Governor Walz, acted out of politically motivated violence.

40,000 tourists stranded in Israel amid airspace shutdown over Iran conflict

Approximately 40,000 tourists are stranded in Israel following the closure of the country’s airspace amid escalating hostilities with Iran, the Israeli Ministry of Tourism reported on Monday.

The ministry has set up a virtual office to provide information via email (virtual@goisrael.gov.il) and phone (+972-53-583-5808), as well as a Facebook page called Israel Virtual Tourist Office.

Israeli Tourism Minister Haim Katz is in contact with hotels and accommodations across the country to offer support to tourists in need, the ministry added.

Many stranded travelers are considering crossing overland into Jordan or Egypt to seek flights from those countries. The Israel Airports Authority reminded the public that land border crossings remain open.

Three German tourists stranded in Jerusalem told EFE today that they have not received any assistance from their country’s embassy in Israel, and their primary option currently is to cross into Jordan to catch a flight from there.

Since early Friday morning, Israel launched operations against Iran, targeting military personnel and infrastructure, including energy and nuclear facilities, as well as numerous residential areas in Tehran.

In response, Iran has fired hundreds of ballistic missiles at Israel, some of which have struck various locations across the country, leaving at least 24 dead so far, according to Israeli authorities.

Iranian health officials report at least 224 deaths, mostly civilians, including at least 17 senior military officials—nine from the Revolutionary Guard—and more than a dozen nuclear scientists.

The Israeli military has warned that many more “targets” remain, while Iran’s Revolutionary Guard declared on Monday that it will continue missile attacks against Israel until its “destruction.”
