Moon ‘wobble’ and climate change could mean ‘double whammy’ of flooding in 2030s, NASA warns – The Washington Post

In the coming decades, higher tides coupled with sea-level rise will cause U.S. coastlines to experience a “dramatic” uptick in flooding, a new NASA study finds.

By the mid-2030s, scientists project that there could be a “rapid” increase in the frequency of high-tide flooding in several parts of the country, according to the report published last month in the Nature Climate Change journal by the NASA Sea Level Change Team at the University of Hawaii.

“We’re going to have sort of a double-whammy,” William Sweet, an oceanographer at the National Oceanic and Atmospheric Administration (NOAA) and author of the study, said Wednesday. “It means that coastal communities — unless they adapt and fortify — are likely to expect even greater flooding than they might otherwise.”

The increase in flooding is caused in part by the moon’s “wobble.” As it orbits Earth, the satellite’s angle relative to the equator changes over time. This phenomenon — spanning an 18.6-year period — influences how tides ebb and flow.

One half of this cycle subdues tides, making the high tides lower and the low tides higher. The second half amplifies them.

This latter part, combined with sea-level rise — a product of climate change — is what will lead to greater flooding in the next two decades, the study concludes.

To explain this phenomenon, one of the report’s authors, Gary Mitchum — associate dean at the University of South Florida’s College of Marine Science — likened it to a person flapping at water inside of a bathtub. While the liquid may not immediately overflow, the probability rises when more water is added.

“The little wave is the tide and the amount of water in the bathtub is sea-level rise,” Mitchum said. “The two are completely unrelated. But the combination of the two means that you’re liable to get sloshing out of your bathtub more often when you have sea-level rise and you have a bigger wave.”

According to the study, the most pronounced effects of this combination will be seen during the mid-2030s and into the 2040s, when the lunar cycle shifts again. However, some of the impacts are already being felt.

“It’s already occurring now, and they’re likely to continue to worsen as time goes on,” Sweet said.

Water spilling into communities from tidal effects is often thought of as a nuisance and happens regularly in coastal cities. Yet, a NOAA report published Wednesday notes tidal floods are increasing.

From May 2020 to April 2021, some cities along the Southeast Atlantic and Gulf coasts have either set or tied records for the amount of high-tide flooding — with Corpus Christi and Galveston in Texas and Bay St. Louis-Waveland, Miss., experiencing more than 20 days of flooding, according to NOAA.

The uptick in flooding caused by high tides is a trend that is expected to continue, according to the NOAA report. By 2030, seven to 15 days of such flooding is expected nationally. Two decades later, estimates indicate that there could be an average of 25 to 75 days a year.

These floods are much more than a minor inconvenience, said Phil Thompson, director of the University of Hawaii Sea Level Center, who was also part of the study.

“You might have a situation where a business might have its parking lot flooded 10 or 15 times in a month — that’s not a nuisance any longer. That’s a significant economic impact on that person,” Thompson said. “It’s really the accumulated impact of many small, seemingly minor issues. But when a minor issue occurs chronically, it becomes a bigger problem.”

While the predictions appear grim — with researchers saying not much can be done to change their estimates for the next few years — there are some measures that can be taken, said Ben Hamlington, NASA Sea Level Change Team’s lead.

In the short term, local communities have to adapt to changing environmental conditions and limit the impacts of sea-level rise. In the long-term, he said the global community must find ways to mitigate climate change.

“The goal needs to be to try to limit global warming and keep the sea-level rise that we see as low-level as possible — for instance, by reducing our emissions — in order to reduce some of these impacts,” Hamlington said. “So there are these bigger global discussions that play a very important role here.”

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.

This report by The Canadian Press was first published Sept. 9, 2024.
