Mediterranean diet named best diet for 2023

CNN
 — 

The gold medals are piling up. For the sixth year in a row, the Mediterranean style of eating earned the title of best overall diet, according to 2023 ratings announced Tuesday by U.S. News & World Report. Meals from the sunny Mediterranean also ranked first in the categories of diet best diet for healthy eating and best plant-based diet, the report said.

In two new categories added for 2023, the Mediterranean tied with the cholesterol-lowering TLC (Therapeutic Lifestyle Changes) and flexitarian diets as best family-friendly diet, and with DASH (dietary approaches to stop hypertension) for best bone and joint health diet.

“We’re always looking for more health conditions that we can address. But often there’s not enough scientific data examining diet X and condition X,” said Gretel Schueller, managing editor of health for U.S. News & World Report, who oversees the annual diet ranking.

“However, bone and joint health is an area where there’s a fair amount of scientific literature,” Schueller said. “We also recognize our population is aging so focusing on diets that can increase the quality of life among older individuals is an important element.”

Also new this year: Reviewers only ranked 24 diets instead of the 40 or so diets analyzed in past years. Five diets from the original list — vegetarian, vegan, Nordic, the traditional Asian and the glycemic index — were integrated by judges into the Mediterranean and other diets due to their underlying plant-based principles.

“The take-home message here is the recognition that the Mediterranean diet is really not just about the foods around the Mediterranean,” Schueller said. “You can take the the lessons and the approach of the Mediterranean eating pattern and apply it to any cuisine in any country.”

That approach is reflected within two new diets — Keyto and Pritikin — that were added to the review for 2023, Schueller said. (Yes. that’s Keyto with a Y.)

“We recognize that more and more people are eating sort of a plant-forward or plant-based diet or at least trying to,” she said. “The keto with a Y diet is supposed to be a flexible, low-carb Mediterranean plan.

“The Pritikin diet focuses on low-fat, high-fiber eating of whole foods, and is fairly flexible,” she added. “We are seeing a push towards eating more whole, unprocessed foods, which I think is a great thing.”

Numerous studies have found the Mediterranean diet can reduce the risk for diabetes, high cholesterol, dementia, memory loss, depression and breast cancer. The diet, which is more of an eating style than a restricted diet, has also been linked to stronger bones, a healthier heart and longer life.

The diet features simple, plant-based cooking, with the majority of each meal focused on fruits and vegetables, whole grains, beans and seeds, with a few nuts and a heavy emphasis on extra-virgin olive oil. Fats other than olive oil, such as butter, are consumed rarely, if at all, and sugar and refined foods are reserved for special occasions.

Red meat is used sparingly, usually only to flavor a dish. Eating healthy, oily fish, which are packed with omega-3 fatty acids, is encouraged, while eggs, dairy and poultry are eaten in much smaller portions than in the traditional Western diet.

Social interactions during meals and exercise are basic cornerstones of the Mediterranean style of eating. Lifestyle changes that are part of the diet include eating with friends and family, socializing over meals, mindfully eating favorite foods, as well as mindful movement and exercise.

Just as they did in 2022, the DASH and the flexitarian diet tied for second place in best overall diet. Similar to the Mediterranean style of eating, these diets reduce or eliminate processed foods and stress packing your plate with fruits, vegetables, beans, lentils, whole grains, nuts and seeds.

The DASH diet emphasizes limiting salt intake in its goal to reduce blood pressure, while the flexitarian diet, true to its name, allows an occasional indulgence of meat or poultry.

A panel of 33 experts examined top diets and ranked them in several categories: Did the diet include all food groups; was it evidence based; are needed foods available at any supermarket; how easy is the diet to prepare, and did it use additional vitamins or supplements.

“We focused on quality over quantity,” Schueller said. “Our reviewers felt there are some diets out there that are so wacky they’re not worth giving time to, such as the Dukan diet, which we no longer rank.”

The worst diet award went to the raw foods diet this year, at least in part due to the lack of nutritional completeness, which has raised safety concerns among the reviewers. Because followers can only eat unprocessed foods that haven’t been cooked, microwaved, irradiated, genetically engineered or exposed to pesticides or herbicides, reviews consider the diet almost impossible to follow.

The popular keto diet, along with the modified keto, was ranked 20 out of the 24 diets, followed by Atkins, SlimFast and Optavia. These diets emphasize eating high-protein or high-fat foods with minimal carbohydrates and receive low rankings because they are extremely restrictive, hard to follow and eliminate entire food groups.

Despite keto’s low overall rating, reviewers gave the keto diet first place for best short-term weight loss diet, Schueller said, quickly adding that these diets are not considered healthy as a lifestyle.

“These are the diets for someone who’s got a wedding or an event they want to go to in the next few months,” she said. “Will you lose weight in the short term? Absolutely. Will you keep it off for the next two years? Probably not.”

In the category of best (long-term) weight-loss diet, WW (formely called Weight Watchers) came in first, with DASH and TLC tied for second. WW also got top honors in the best (commercial) diet program, followed by NOOM and Jenny Craig.

Flexitarian and TLC shared the gold in the category of easiest diet to follow, while the Mediterranean and DASH diets tied for third.

The DASH diet took top honors as best diet for heart health and for people with diabetes, followed by the Mediterranean, flexitarian and Ornish diets. The Ornish diet was created in 1977 by Dr. Dean Ornish, founder of the nonprofit Preventive Medicine Research Institute in California.

The Ornish diet is combined with stress-management techniques, exercise, social support and smoking cessation, and according to Ornish is the only scientifically proven program to reverse heart disease without drugs or surgery

On Snake Island, the rocky Black Sea outcrop that became a Ukraine war legend

Leave a comment


Snake Island, Ukraine
CNN
 — 

Snake Island has a special place in Ukraine’s folklore, now more than ever. Its defiant defense – when a Russian warship was famously told to “go f*** yourself” – and then reconquest rallied a nation in the early months of the conflict with Russia, puncturing the myth of the invaders’ superiority.

Now, whipped by winter winds, it remains firmly in Ukrainian hands – a speck of rock that has both symbolic and strategic significance.

A CNN team became the first foreign media to visit the island since it was recaptured in June, and to speak with the commander of the operation that led to its liberation.

A few acres of rock and grass, treeless and difficult to access, Snake Island, also known as Zmiinyi Island, lies around 30 miles (48 kilometers) off the Ukrainian coast, near its maritime border with Romania.

Getting there proved challenging: An hour being pitched from wave to wave in a small boat, showered with spray, in sub-freezing temperatures. The Black Sea can be unforgiving, and so can its hazardous coastline. On the way back our dirigible boat got stuck on a sandbar, and it took six hours before we were transferred, one-by-one, to another vessel in the darkness.

Snake Island is now a desolate place, strewn with wreckage, its few buildings reduced to shells, its half-sunken jetty battered by the tide. It’s a graveyard of expensive military hardware – and is littered with unexploded ordnance and mines. This is not a place to be careless.

The CNN team saw at least four different kinds of landmines, Russian Pantsir surface-to-air missile systems, and an almost intact Tor anti-air missile complex. There was also the carcass of a Russian military helicopter that was hit.

Wondering among the wreckage, in a surreal scene, were dozens of cats, probably the descendants of the lighthouse pets from a more peaceful time.

Ukraine keeps a small military presence on the island as an observation mission. One of that detachment is actually Russian, a volunteer with the Ukrainian forces who goes by the call-sign Fortuna.

He’d been living with his family in Ukraine. “And here comes Russia attacking us. If some other country had attacked us we’d fight too.”

Nowadays, he says, the Russians aren’t doing much attacking, at least in this corner of Ukraine.

“At this stage the Russians only perform air strikes,” Fortuna told CNN. “So we can hear them coming. Plus we have observers all along the perimeter and we receive intelligence. So usually we are warned about a possible attack.”

Occasionally they will see a Russian warship in the distance.

“We need to be on guard 24/7 so we never get bored. There is always something to get busy with,” Fortuna says.

The troops here can’t communicate with their families. Even when there is a signal, turning on your phone invites a strike. The small boats used to ferry supplies are often unable to make the trip, so a rotation here can get extended by the elements, sometimes for a week.

Snake Island fell in the first few days of the invasion in February, as Ukraine struggled on multiple fronts against Russian forces. But before it did, there was a show of defiance that immediately became a meme for Ukraine’s determined resistance.

Ordered to surrender by an approaching Russian vessel, one of the small detachment there responded by radio: “Russian warship: Go f*** yourself.”

Those words were echoed on everything from T-shirts to postage stamps and road signs.

One of the small detachment on the island told CNN it was a pivotal moment, encouraging people to fight and volunteer.

The man who led the operation to expel the Russians from the island, after they occupied it for several months, cannot reveal his real name. As an officer in military intelligence he goes by the call-sign Shakespeare.

“There are just four or five officers like me in Ukraine,” he told CNN. “if I give any details, everybody will recognize me.”

But he did provide a detailed account of the plan to retake the island, which was successful by the end of June.

Much of the hard work was done in May, when exposed Russian positions were targeted. “It was all about choosing the right kind of artillery and combination of artillery,” Shakespeare said.

“The Russians made a mistake in estimating we cannot reach them there. They thought we could only fire multiple rocket launchers at them, so they installed anti-air systems on the island. They were able to intercept our rockets, but we used complex strikes.”

“They just lost manpower and lots of expensive vehicles for nothing. This was their main mistake.”

French-made CAESARS as well as Grad rocket launchers were used, he said, though he was less complimentary about the Ukrainian-developed Bogdana howitzer, which has a range of 40 kilometers (25 miles).

“It was breaking more than firing,” Shakespeare told CNN.

They were plenty of challenges, particularly as launching artillery across the sea is nothing like firing it across land. “Different conditions, so aiming is complicated,” he added. Reconnaissance drones helped make the artillery fire more accurate.

The Ukrainians also used the Turkish-supplied Bayrakhtar drone before the Russians introduced electronic warfare measures and air defenses on the island.

But the Russians had to ship equipment from Sevastopol in Crimea to defend the island. And that was their second mistake, Shakespeare said. This was a long and exposed supply line vulnerable to Ukrainian anti-ship missiles.

Shakespeare recalled the initial landing at the end of June, after Russian positions had been pummeled.

“It was a unit from Special Ops Forces and deminers from the marine corps. Combat swimmers, divers. They checked water for the mines. Then others could approach the island on the vessels.”

What they found was a deserted scrap yard.

“There was nobody there … They left in a hurry leaving behind ammunition and equipment.”

That included the nearly intact Tor complex. “If they’d had the time, they would have blown it up,” Shakespeare added.

Besides the huge boost to Ukrainian morale, the recapture of Snake Island had a strategic purpose.

“Controlling Snake Island allows you to control the mouth of Danube. Without securing (the) island signing the grain deal would have been impossible,” Shakespeare said, referring to the UN-brokered grain initiative agreed in July that allowed Ukraine to restart exports through the Black Sea.

Our visit is necessarily brief. Our hosts don’t want Russia to have the time to plan something and the weather is deteriorating. In the slate-gray of the winter afternoon we are whisked away for our rendezvous with the sandbar.

But the mystery of the island stays with you. It is reputed to be the burial place of Achilles and once had a Greek temple. It was fought over by the Russian and Ottoman empires. It seems that every crag and cave hides a story.

Now there is a modern legend to add to those fables.

Oil tankers are getting stuck in the Black Sea. That could become a problem

Leave a comment



CNN
 — 

A bottleneck is building across an important trading route for oil, which if left unresolved could knock global supply and boost prices at a fragile moment for energy markets.

As of Thursday, 16 oil tankers traveling south from the Black Sea were waiting to cross the Bosphorus strait into the Sea of Marmara, an increase of five from Tuesday, according to a report from Istanbul-based Tribeca Shipping Agency. A further nine tankers were waiting to cross southbound from the Sea of Marmara through the Dardanelles strait into the Mediterranean.

The snarl-up in waterways controlled by Turkey, which Turkish officials said is mostly affecting crude oil shipments destined for Europe, has caught the attention of UK and US government officials who are now in talks with Ankara to resolve the growing impasse.

The snag is linked to a Western price cap on Russian oil that came into effect on Monday. The cap is supposed to limit the Kremlin’s revenues without adding to stress on the global economy by reducing supply. But Turkey is insisting that vessels prove they have insurance that will pay out in light of the new sanctions, before allowing them to pass through the straits linking the Black Sea and Mediterranean.

Although currently causing no disruption to global oil supply and thus prices, the hold-up could become a problem if left unresolved, said Jorge Leon, senior vice president for oil market analysis at Rystad Energy. “This is a very popular route around the world for global trade and specifically for crude,” he told CNN Business.

Countries including Russia, Kazakhstan and Azerbaijan use the Turkish straits to get their oil to world oil markets.

The traffic jam in the Turkish straits arose following the imposition this week of the price cap on Russian oil. The cap bars ship owners carrying Russian oil from accessing insurance and other services from European providers unless the oil is sold for $60 a barrel or less.

In light of the cap, Turkish maritime authorities are concerned about the risk of accidents or oil spills involving uninsured vessels, and are preventing ships from passing through Turkish waters unless they can provide additional guarantees that their transit is covered.

In a notice issued last month by Turkey’s government ahead of the price cap, maritime director general Ünal Baylan said that given “catastrophic consequences” for the country in the event of an accident involving a crude tanker, “it is absolutely required for us to confirm in some way that their [protection and indemnity] insurance cover is still valid and comprehensive.”

The International Group of P&I Clubs, which provides protection and indemnity insurance for 90% of the goods shipped by sea, has said it cannot comply with the Turkish policy.

The Turkish government’s requirements “go well beyond the general information that is contained in a normal confirmation of entry letter” and would require P&I Clubs to confirm coverage even in the event of a breach of sanctions under EU, UK and US law, the UK P&I Club said in a statement.

Turkish officials say this position is “unacceptable” and on Thursday reiterated demands for letters from insurers. “The majority of the crude oil tankers waiting to cross the strait are EU ships and a majority of the petrol is destined for EU ports,” the Turkish maritime authority said in a statement.

“It is difficult to understand why EU-based insurance companies are refusing to provide this letter… for ships that belong to the EU, carrying crude oil to [the] EU when the sanctions in question have been set forth by the EU,” it added.

Western officials, clearly worried about potential disruption to oil supply, say they are in talks with Turkey’s government to resolve the situation.

US Deputy Treasury Secretary Wally Adeyemo told Turkish Deputy Foreign Minister Sedat Onal on a call that the price cap only applies to Russian oil and “does not necessitate additional checks on ships” passing through Turkish waters.

“Both officials highlighted their shared interest in keeping global energy markets well supplied by creating a simple compliance regime that would permit oil to transit the Turkish straits,” the Treasury Department said in a statement.

“The UK, US and EU are working closely with the Turkish government and the shipping and insurance industries to clarify the implementation of the Oil Price Cap and reach a resolution,” according to a statement from the UK Treasury.

“There is no reason for ships to be denied access to the Bosporus Straits for environmental or health and safety concerns,” it added.

Despite the backlog of tankers, the average waiting time to cross the Bosphorus strait is still well below where it was this time last year, according to Leon of Rystad Energy. “Given the reaction from UK and US officials, my hunch is that this is going to be resolved very soon,” he said.

US and China in first South China Sea encounter since Xi-Biden meeting

Leave a comment


Seoul, South Korea
CNN
 — 

The United States and Chinese militaries exchanged harsh words Tuesday after a US Navy warship performed the first freedom of navigation operation (FONOP) in the South China Sea since the leaders of the two powers met earlier this month in an attempt to ease tensions.

In a statement, the Chinese military claimed the USS Chancellorsville, a guided-missile cruiser, “illegally entered the waters near China’s Nansha Islands and reefs without the approval of the Chinese government.”

The move, according to China, shows the “US is a true producer of security risks in the South China Sea.” A statement from the US Navy’s 7th Fleet later Tuesday called the PLA’s account “false” and a continued misrepresentation of US actions in the South China Sea.

The encounter is the first in the South China Sea since US President Joe Biden and Chinese leader Xi Jinping met in person on the sidelines of the G20 summit in Indonesia two weeks ago, according to a US Navy spokesperson.

After that meeting, Biden said he and Xi made progress on cooling tensions in some areas but came nowhere near resolving the litany of issues that have helped drive the US-China relationship to its lowest point in decades.

China claims “indisputable sovereignty” over almost all of the 1.3 million square mile South China Sea as well as most of the islands within it, including the Nansha Islands, known outside China as the Spratlys.

They are home to military installations China has built on features claimed by other nations around the South China Sea, including the Philippines, a US treaty ally, and Vietnam.

People’s Liberation Army Col. Tian Junli, spokesman for the Southern Theater Command, said the PLA organized naval and air forces to follow, monitor, warn and eventually drive away the US warship.

China says this action by the US military “seriously infringes on China’s sovereignty and security” and is “hard proof is that the US is seeking maritime hegemony and militarizing the South China Sea,” according to a statement on its official Weibo account.

In its statement, the US Navy said the US cruiser conducted the FONOP “in accordance with international law and then continued on to conduct normal operations in waters where high seas freedoms apply.”

“The PRC’s behavior stands in contrast to the United States’ adherence to international law and our vision for a free and open Indo-Pacific region. All nations, large and small, should be secure in their sovereignty, free from coercion, and able to pursue economic growth consistent with accepted international rules and norms,” the US statement added.

Biden said he made that point to Xi at their meeting.

“I was clear that we will defend American interests and values, promote universal human rights and stand up for the international order and work in lockstep with our allies and partners,” Biden said.

Tuesday’s FONOP is an early indication Biden is not backing down on that promise.

“The operation reflects our commitment to uphold freedom of navigation and lawful uses of the sea as a principle. The United States is defending every nation’s right to fly, sail, and operate wherever international law allows, as USS Chancellorsville did here. Nothing the PRC (China) says otherwise will deter us,” Tuesday’s US Navy statement said.

Alaska crab season cancelled after billions vanish

Leave a comment



CNN
 — 

The Alaska snow crab harvest has been canceled for the first time ever after billions of the crustaceans have disappeared from the cold, treacherous waters of the Bering Sea in recent years.

The Alaska Board of Fisheries and North Pacific Fishery Management Council announced last week that the population of snow crab in the Bering Sea fell below the regulatory threshold to open up the fishery.

But the actual numbers behind that decision are shocking: The snow crab population shrank from around 8 billion in 2018 to 1 billion in 2021, according to Benjamin Daly, a researcher with the Alaska Department of Fish and Game.

“Snow crab is by far the most abundant of all the Bering Sea crab species that is caught commercially,” Daly told CNN. “So the shock and awe of many billions missing from the population is worth noting – and that includes all the females and babies.”

The Bristol Bay red king crab harvest will also be closed for the second year in a row, the agencies announced.

Officials cited overfishing as their rationale for canceling the seasons. Mark Stichert, the groundfish and shellfish fisheries management coordinator with the state’s fish and game department, said that more crab were being fished out of the oceans than could be naturally replaced.

“So there were more removals from the population than there were inputs,” Stichert explained at Thursday’s meeting.

Between the surveys conducted in 2021 and 2022, he said, mature male snow crabs declined about 40%, with an estimated 45 million pounds left in the entire Bering Sea.

“It’s a scary number, just to be clear,” Stichert said.

But calling the Bering Sea crab population “overfished” – a technical definition that triggers conservation measures – says nothing about the cause of its collapse.

“We call it overfishing because of the size level,” Michael Litzow, the Kodiak lab director for NOAA Fisheries, told CNN. “But it wasn’t overfishing that caused the collapse, that much is clear.”

Litzow says human-caused climate change is a significant factor in the crabs’ alarming disappearance.

Snow crabs are cold-water species and found overwhelmingly in areas where water temperatures are below 2 degrees Celsius, Litzow says. As oceans warm and sea ice disappears, the ocean around Alaska is becoming inhospitable for the species.

“There have been a number of attribution studies that have looked at specific temperatures in the Bering Sea or Bering Sea ice cover in 2018, and in those attribution studies, they’ve concluded that those temperatures and low-ice conditions in the Bering sea are a consequence of global warming,” Litzow said.

Temperatures around the Arctic have warmed four times faster than the rest of the planet, scientists have reported. Climate change has triggered a rapid loss in sea ice in the Arctic region, particularly in Alaska’s Bering Sea, which in turn has amplified global warming.

“Closing the fisheries due to low abundance and continuing research are the primary efforts to restore the populations at this point,” Ethan Nichols, an assistant area management biologist with the Alaska Department of Fish and Game, told CNN.

Stichert also said that there might be some “optimism for the future” as a few, small juvenile snow crabs are starting to appear in the system. But it could be at least three to four more years before they hit maturity and contribute to the regrowth of the population.

“It is a glimmer of optimism,” Litzow said. “That’s better than not seeing them, for sure. We get a little bit warmer every year and that variability is higher in Arctic ecosystems and high latitude ecosystems, and so if we can get a cooler period that would be good news for snow crab.”

Israel and Lebanon reach historic agreement, settling a years-long maritime border dispute

Leave a comment



CNN
 — 

Israel and Lebanon have reached a historic agreement, leaders on each side said separately on Tuesday, settling a years-long maritime border dispute involving major oil and gas fields in the Mediterranean.

The United States has been trying to broker a deal between the neighboring countries over the 860-square-kilometer (332-square-mile) area of the sea that has been under dispute for years.

It includes the Karish oil and gas field and a region known as the Qanaa prospect, which are expected to fall into Israeli and Lebanese waters respectively under the deal. Israel has said it would begin extracting oil and gas from Karish and exporting it to Europe imminently.

“The final version of the offer is satisfactory to Lebanon and meets its demands and preserved Lebanon’s rights of this natural wealth,” Lebanon’s President Michel Aoun said in a statement hours after receiving Israel’s final offer through US mediator Amos Hochstein.

Aoun said he hopes the agreement, which is yet to be signed, will be announced “as soon as possible.”

Israeli Prime Minister Yair Lapid said: “This is an historic achievement that will strengthen Israel’s security, inject billions into Israel’s economy, and ensure the stability of our northern border.”

The draft agreement meets all the security and economic principles laid out by Israel, Lapid said.

The Israeli prime minister will convene the security cabinet on Wednesday followed by a special meeting of the government, he said.

Lebanese officials have said the deal does not mean any “treaty” will be signed with Israel and this agreement is not a step toward normalization of relations between the two countries, which are technically at war.

Earlier Tuesday, Lebanese negotiator and deputy parliament speaker Elias Bou Saab told CNN that “Lebanon felt that [the deal] takes into consideration all of Lebanon’s requirements and we believe the other side should feel the same.”

Meanwhile, Israeli chief negotiator Eyal Hulata said: “All our demands were met, the changes that we asked for were corrected. We protected Israel’s security interests and are on our way to an historic agreement.”

On Tuesday, Lebanese Energy Minister Walid Fayyad also said the French energy company Total, which owns the contract to explore Lebanese waters, would start working on the Qanaa prospect “immediately.”

Talks gained momentum after London-based oil and gas exploration company Energean arrived in June to begin development of the Karish field on Israel’s behalf. Although the Energean ship is well south of the disputed area, part of the field is in an area Lebanon had claimed.

Hezbollah, the powerful Iran-backed Lebanese Shiite milita, had threatened Energean’s gas rig if they started producing gas before a deal had been struck.

On Tuesday, Hezbollah declined to comment when contacted by CNN, but the Iran-backed armed group has previously said it would abide by any agreement signed by the Lebanese government.

The historic agreement does not affect land borders, but it is likely to ease security and economic tensions for both nations.

Lebanon’s caretaker Prime Minister Najib Mikati said on Thursday that an agreement “will circumvent us from a definite war in the region.”

Asteroid that wiped out the dinosaurs also triggered a global tsunami

CNN
 — 

When a city-size asteroid slammed into Earth 66 million years ago, it wiped out the dinosaurs – and sent a monster tsunami rippling around the planet, according to new research.

The asteroid, about 8.7 miles (14 kilometers) wide, left an impact crater about 62 miles (100 kilometers) across near Mexico’s Yucatan peninsula. In addition to ending the reign of the dinosaurs, the direct hit triggered a mass extinction of 75% of animal and plant life on the planet.

When the asteroid hit, it created a series of cataclysmic events. Global temperatures fluctuated; plumes of aerosol, soot and dust filled the air; and wildfires started as flaming pieces of material blasted from the impact re-entered the atmosphere and rained down. Within 48 hours, a tsunami had circled the globe – and it was thousands of times more energetic than modern tsunamis caused by earthquakes.

Researchers set out to gain a better understanding of the tsunami and its reach through modeling. They found evidence to support their findings about the path and power of the tsunami by studying 120 ocean sediment cores from across the globe. A study detailing the findings published Tuesday in the journal American Geophysical Union Advances.

It’s the first global simulation of the tsunami caused by the Chicxulub impact to be published in a peer-reviewed scientific journal, according to the authors.

The tsunami was powerful enough to create towering waves more than a mile high and scour the ocean floor thousands of miles away from where the asteroid hit, according to the study. It effectively wiped away the sediment record of what happened before the event, as well as during it.

“This tsunami was strong enough to disturb and erode sediments in ocean basins halfway around the globe, leaving either a gap in the sedimentary records or a jumble of older sediments,” said lead author Molly Range, who began working on the study as an undergraduate student and completed it for her master’s thesis at the University of Michigan.

Researchers estimate that the tsunami was up to 30,000 times more energetic than the December 26, 2004 Indian Ocean tsunami, one of the largest on record, that killed more than 230,000 people. The energy of the asteroid impact was at least 100,000 times larger than the Tonga volcanic eruption earlier this year.

Brandon Johnson, study coauthor and an associate professor at Purdue University, used a large computer program called a hydrocode to simulate the first 10 minutes of the Chicxulub impact, including the formation of the crater and the beginning of the tsunami.

He included the size of the asteroid and its speed, which was estimated to be moving at 26,843 miles per hour (43,200 kilometers per hour) when it hit the granite crust and shallow waters of the Yucatan peninsula.

Less than three minutes later, rocks, sediments and other debris pushed a wall of water away from the impact, creating a 2.8 mile (4.5 kilometer) tall wave, according to the simulation. This wave subsided as exploded material fell back to Earth.

But as the debris fell, it created even more chaotic waves.

Ten minutes after impact, a ring-shaped wave about a mile high began traveling across the ocean in all directions from a point that was located 137 miles (220 kilometers) away from the impact.

This simulation was then entered into two different global tsunami models, MOM6 and MOST. While MOM6 is used to model deep ocean tsunamis, MOST is part of tsunami forecasting at the National Oceanic and Atmospheric Administration’s Tsunami Warning Centers.

Both models delivered almost the exact same results, creating a timeline of the tsunami for the research team.

An hour after impact, the tsunami had travel beyond the Gulf of Mexico into the North Atlantic Ocean. Four hours post-impact, the waves passed through the Central American Seaway and into the Pacific Ocean. The Central American Seaway once separated North and South America.

Within 24 hours, the waves entered the Indian Ocean from both sides after traveling across the Pacific and Atlantic oceans. And by 48 hours after impact, large tsunami waves had reached most of Earth’s coastlines.

The underwater current was strongest in the North Atlantic Ocean, the Central American Seaway and the South Pacific Ocean, exceeding 0.4 miles per hour (643 meters per hour), which is strong enough to blast away sediments on the ocean floor.

Meanwhile, the Indian Ocean, North Pacific, the South Atlantic and the Mediterranean were shielded from the worst of the tsunami, with lesser underwater currents.

The team analyzed information from 120 sediments that largely came from previous scientific ocean-drilling projects. There were more intact sediment layers in the waters protected from the tsunami’s wrath. Meanwhile, there were gaps in the sediment record for the North Atlantic and South Pacific oceans.

The researchers were surprised to find that sediment on the eastern shores of New Zealand’s north and south islands had been heavily disturbed with multiple gaps. Initially, scientists thought this was because of the activity of tectonic plates.

But the new model shows the sediments being directly in the pathway of the Chicxulub tsunami, despite being 7,500 miles (12,000 kilometers) away.

“We feel these deposits are recording the effects of the impact tsunami, and this is perhaps the most telling confirmation of the global significance of this event,” Range said.

While the team didn’t estimate the tsunami’s impact on coastal flooding, the model shows that the North Atlantic coastal regions and South America’s Pacific coast were likely hit with waves taller than 32.8 feet (20 meters). The waves only grew as they neared the shore, causing flooding and erosion.

Future research will model the extent of global flooding after the impact and how far inland the tsunami’s effects could be felt, according to study coauthor and University of Michigan professor and physical oceanographer Brian Arbic.

“Obviously the greatest inundations would have been closest to the impact site, but even far away the waves were likely to be very large,” Arbic said.

Tropical Storm Ian strengthens in the Caribbean and tracks toward Florida

Leave a comment



CNN
 — 

The ninth named tropical storm of the 2022 Atlantic hurricane season has formed across the central Caribbean Sea, and is forecast to turn into a hurricane before hitting Florida next week. If it does, it will be the first major hurricane to impact the state since 2018.

Tropical Storm Ian was located about 270 miles south-southeast of Kingston, Jamaica, as of 2 p.m. Saturday and moving west at 16 mph, according to the National Hurricane Center. “Significant strengthening is forecast during the next few days,” the center said.

The forecast shows Ian “as a major hurricane over the eastern Gulf when it is approaching the west coast of Florida,” after briefly passing over Cuba at or near major hurricane strength, the center said Friday. Much of the Gulf Coast of Florida, including the eastern Panhandle, could be at risk.

Forecast models on Saturday afternoon vary on where Ian may make landfall on Florida’s coast. The European model shows landfall near Tampa on Thursday morning, while the American model shows landfall near Pensacola Friday morning.

The official hurricane center track splits the difference between the models, showing landfall north of Tampa on Thursday morning.

Florida Gov. Ron DeSantis on Saturday expanded an emergency order from 24 counties to include the whole state, citing “foregoing conditions, which are projected to constitute a major disaster.”

“The Florida Division of Emergency Management, working together with the National Hurricane Center to evaluate weather predictions, has determined there is a continuing risk of dangerous storm surge, heavy rainfall, flash flooding, strong winds, hazardous seas, and isolated tornadic activity for Florida’s Peninsula and portions of the Florida Big Bend, North Florida, and Northeast Florida,” the order states.

Tropical storm-force winds could begin to affect southwest Florida early Tuesday, with landfall possible on Wednesday or Thursday.

After strengthening overnight, the storm – earlier known as Tropical Depression Nine – has maximum sustained winds of 45 mph (75 km/h) and is forecast to reach hurricane status within the next two days as it approaches the Cayman Islands by early Monday. Further strengthening is anticipated as the system approaches and crosses western Cuba by Monday evening.

“Ian is likely to be near major hurricane intensity when it approaches western Cuba,” the hurricane center said. “Since Ian is not expected to remain over Cuba long, little weakening is expected due to that land interaction.”

If it strengthens to a Category 3 or higher before reaching Florida, it would be the first major hurricane to make landfall there since Hurricane Michael in 2018, which was a monster Category 5 storm when it collided with the Florida panhandle. Michael also underwent rapid intensification before it made landfall, a phenomenon which has been made more likely as ocean temperatures warm due to the climate crisis.

A hurricane warning was issued for Grand Cayman, and a tropical storm watch is in effect for Little Cayman and Cayman Brac in the Cayman Islands and for Jamaica.

DeSantis on Friday requested federal emergency assistance in anticipation of the threat when he declared the state of emergency for two dozen counties. Under the state-level emergency order, members of the Florida National Guard will be activated and on standby awaiting orders.

The governor urged those in the potential path of the storm to prepare.

“This storm has the potential to strengthen into a major hurricane and we encourage all Floridians to make their preparations,” DeSantis said in a news release. “We are coordinating with all state and local government partners to track potential impacts of this storm.”

It has been a slow start to what was forecast to be an above-average hurricane season. Only one storm has made landfall in a US territory, and no hurricane has made landfall or threatened the contiguous states.

Now, a week past the peak of hurricane season, the tropics seem to have woken up, and forecasters are concerned people have let down their guard.

“After a slow start, the Atlantic hurricane season has ratcheted up quickly,” Phil Klotzbach, research scientist at Colorado State University, tweeted.

“People tend to lower their guard and think, oh, yeah, we’re out of the woods,” Maria Torres, hurricane center spokesperson, told CNN. “But in reality, the season continues. We are still in September; we still have October to go. Anything that forms over either the Atlantic or the Caribbean is something that we need to keep monitoring very closely.”

The Atlantic hurricane season ends November 30.

No matter what, if you live in the Caribbean, Florida and other states along the Gulf Coast, pay attention to the updated forecasts this weekend into early next week.
