Relentless drought in China, East Africa, the U.S. West and northern Mexico, devastating floods in Pakistan and Kentucky, scorching heat waves in Europe and the Pacific Northwest, destructive cyclones in southern Africa and intense hurricanes in the U.S. and Central America make up just some of the recent extreme weather events that scientists have long predicted would be more intense with a warming climate.

“With just over one degree of warming since pre-industrial times, we are already seeing more extreme weather patterns,” said Elizabeth Robinson, director of the Grantham Research Institute in London.

Scientists have been tracking precisely how much the climate has already changed due to human activity. Temperatures around the world have been inching upwards.

The average global temperature today, which tends to be compared to estimates for the pre-industrial era that kickstarted the mass burning of fossil fuels, has shot up between 0.9 and 1.2 degrees Celsius (1.6 to 2 degrees Fahrenheit) since 1850, in large part due to human activity, according to estimates in the most recent report by the Intergovernmental Panel on Climate Change. Most of that warming has happened from 1975 onwards, at a rate of 0.15 Celsius (0.27 Fahrenheit) to 0.2 Celsius (0.36 Fahrenheit) per decade.

Most people are living in areas that have heated up more than the global average, “partly that is urbanization — people move into cities, which are urban heat islands — and partly populations growing,” Robinson said. Urban areas, packed with plenty of heat-absorbing infrastructure like roads and buildings and less cooling tree cover, become “islands” of warmer weather.

Sea levels, which have swelled due to both warming, expanding oceans and the melting of ice over land, have also been jumping up more rapidly. In the twentieth century, seas were rising by about 1.4 millimeters (0.06 inches) a year, but that’s doubled to 3.6 millimeters a year (0.14 inches) in the past fifteen years, data suggests. Seas have risen by about 21 to 24 centimeters (8 to 9 inches) so far since 1880 on average, according to estimates, with the IPCC suggesting this will likely be up to 43 to 84 centimeters (17 to 33 inches) by 2100.

While the climate and global temperatures have fluctuated throughout the Earth’s history, it is the rate of change that is most alarming to researchers. Fossil fuels — made up of ancient decomposing plants and animals deep in the earth — have been dug up at extraordinary rates. Scientists are now starting to pinpoint “details about rates and magnitudes and timing of changes” as well as the varying impact on regions, said Brown University climate scientist Kim Cobb.

With the planet already facing the effects of climate change, adapting to hazards is one major way humans can limit the damage. Weather-related disaster deaths are generally trending lower globally as forecasts, preparedness and resilience improves, scientists say.

“The extent to which people are harmed by an extreme weather event is strongly influenced by government policies,” Robinson said, but added that “there are limits to adaptation.”

The Bill and Melinda Gates Foundation says it will commit $1.2 billion to the effort to end polio worldwide.

The money will be used to help implement the Global Polio Eradication Initiative’s strategy through 2026. The initiative is trying to end the polio virus in Pakistan and Afghanistan, the last two endemic countries, the foundation said in a statement Sunday.

The money also will be used to stop outbreaks of new variants of the virus. The announcement was made Sunday at the World Health Summit in Berlin.

The foundation says in a statement on its website that it has contributed nearly $5 billion to the polio eradication initiative. The initiative is trying to integrate polio campaigns into broader health services, while it scales up use of the novel oral polio vaccine type 2.

The group also is working to make national health systems stronger, so countries are better prepared for future health threats, the statement said.

“The last steps to eradication are by far the toughest. But our foundation remains dedicated to a polio-free future, and we’re optimistic that we will see it soon,” said foundation CEO Mark Suzman.

The eradication initiative is a public-private partnership led by a group of national governments that includes the Gates Foundation, Rotary International, the World Health Organization and the U.S. Centers for Disease Control and Prevention.

Sitting on a 7,000-hectare stretch of land in southwest Florida, Babcock Ranch has made a name for itself as the first solar-powered town in the United States. Its power comes from nearly 700,000 solar panels that supply energy to more than 2,000 homes and other buildings, including a health center and schools.

Syd Kitson, founder of the planned community, envisioned an environmentally friendly energy-efficient city. His dream became a reality in 2018.

“I believe deeply in respecting the environment and wanted to prove that you could build this new city and work hand-in-hand with the environment,” said Kitson, CEO of the real estate firm Kitson & Partners. “Our water management system is based around natural floodways. We also have 7,000 hectares we are preserving.”

The preserve protects natural habitats, scenic landscapes and water resources.

“It was just the kind of community my husband and I were looking for,” Shannon Treece told VOA. “We liked that the town was built for sustainability, including solar energy.”

Today, Babcock Ranch is also known as the town that came out practically unscathed Sept. 28, when Hurricane Ian came roaring through the area bringing record-breaking storm surges and winds over 160 kph.

Nearby Fort Myers by the Gulf of Mexico was devastated.

Babcock Ranch was built on a higher elevation to be above the storm surge. And the buildings were constructed to withstand hurricane-force winds.

Because of that, Shannon Treece and her family are among the 4,600 residents who decided to ride out the storm.

“It was a little scary,” she said of being in a hurricane for the first time. “We couldn’t see anything since we had blocked all the windows with storm shutters, but we could hear debris hitting the house. I am glad our house held up.”

Nancy Chorpenning and her husband also decided to stay put.

“The hurricane sounded like a locomotive coming through. But we never lost our electricity, access to the internet or our water,” she told VOA.

That’s because power lines from Babcock Ranch’s solar array and utility plants are underground, which shields them from high winds and bad weather, Kitson said.

Huge retaining ponds protect the homes from flooding, and the streets are designed to soak up floodwaters.

When building the town, “we spent a lot of time making sure Babcock Ranch was storm ready,” Kitson said. “We had minor damage from Hurricane Ian, like some downed small trees and torn roof shingles, but within a day, we were almost back to normal.”

Chorpenning thinks there are lessons to be learned from Babcock Ranch.

“We can be a model for other communities, showing the importance of water management and using solar energy,” she said. “We’re also showing how neighborhoods can live in concert with nature, partly by requiring that native plant species be planted in the community.”

The blueprint for the town is to grow into a much larger city. The developers have their sights set on constructing thousands more of the environmentally friendly homes, which would increase the population to 50,000 residents.

“I hope we are setting a good example for others to follow as we continue to protect the natural environment at the same time,” Kitson said.

Astronomers have observed the brightest flash of light ever seen, from an event that occurred 2.4 billion light-years from Earth and was likely triggered by the formation of a black hole. 

The burst of gamma rays — the most intense form of electromagnetic radiation — was first detected by orbiting telescopes Sunday, and its afterglow is still being watched by scientists across the world. 

Astrophysicist Brendan O’Connor told AFP that gamma ray bursts that last hundreds of seconds, as this one did, are thought to be caused by dying massive stars, greater than 30 times bigger than our sun. 

The star explodes in a supernova, collapses into a black hole, then matter forms in a disk around the black hole, falls inside, and is spewed out in a jet of energy that travels at 99.99% the speed of light. 

The flash released photons carrying a record 18 teraelectronvolts of energy — that’s 18 with 12 zeros behind it — and it has impacted longwave radio communications in Earth’s ionosphere. 

“It’s really breaking records, both in the amount of photons, and the energy of the photons that are reaching us,” said O’Connor, who used infrared instruments on the Gemini South telescope in Chile to take fresh observations early Friday. 

“Something this bright, this nearby, is really a once-in-a-century event,” he added. 

“Gamma ray bursts in general release the same amount of energy that our sun produces over its entire lifetime in the span of a few seconds — and this event is the brightest gamma ray burst.” 

The gamma ray burst, known as GRB 221009A, was first spotted by telescopes including NASA’s Fermi Gamma-ray Space Telescope, the Neil Gehrels Swift Observatory, and the Wind spacecraft Sunday morning Eastern time.  

1.9 billion-year-old movie

It originated from the direction of the constellation Sagitta and traveled an estimated 1.9 billion years to reach Earth — less than the current distance of its starting point, because the universe is expanding. 

Observing the event now is like watching a 1.9 billion-year-old recording of those events unfold before us, giving astronomers a rare opportunity to glean new insights into things like black hole formation. 

“That’s what makes this sort of science so addictive — you get this adrenaline rush when these things happen,” said O’Connor, who is affiliated with the University of Maryland and George Washington University. 

He added that though the initial burst may have been visible to lucky amateur astronomers, it has since faded out of their view. 

Over the coming weeks, he and others will continue watching for the signatures of supernovas at optical and infrared wavelengths, to confirm that their hypothesis about the origins of the flash are correct, and that the event conforms to known physics.

Supernova explosions are also predicted to be responsible for producing heavy elements — such as gold, platinum, uranium — and astronomers will also be on the hunt for their signatures. 

Astrophysicists have written in the past that the sheer power of gamma ray bursts could cause extinction-level events here on Earth. 

But O’Connor pointed out that because the jets of energy are very tightly focused, and aren’t likely to arise in our galaxy, this scenario is not something we should worry much about.

Young researchers and students are competing in a disaster challenge at a natural hazards forum in the Australian city of Brisbane.

The government-funded organization Natural Hazards Research Australia has said more Australians “than ever before are exposed to the damage and destruction of floods, bushfires, cyclones, heatwaves and storms.”

It reported that Australia has experienced 28 disasters that have cost more than $630 million, and 16 of these have occurred since 2000.

Experts have said that research is essential to improve Australia’s readiness for natural calamities.

At the inaugural Natural Hazards Research Forum in Brisbane, young researchers have been asked to solve a key conundrum in preparing communities for floods, fires and storms; how can disaster authorities get potentially life-saving advice to the “unengaged, the moving,” such as tourists or “the hard to reach”?

The winning entry aims to reach international tourists through Wi-Fi — essentially captive portals that compel visitors in flood or fires zones, for example, to watch a survival video before they can log onto the Internet at hotels, cafes or other destinations.

Mark Owens from the Country Fire Authority, an emergency service in the Australians state of Victoria, told VOA that the videos would be tailored for various locations and seasons.

“Making sure the message we actually get to them will actually change their behavior but also get them to do that for the future again and again, and that is why the videos will be tailored and changed seasonally, or, you know, if there is a La Niña coming through again,” he said. “So, you know, it might then really focus on floods for a big period of time instead of bushfire.”

Parts of Victoria state are currently facing one of the biggest floods in decades.

There have been rescues and evacuations along the Maribyrnong River in the city of Melbourne.

Thousands of people are also under evacuation orders for flooding in the states of New South Wales and Tasmania.

Two climatic phenomena — La Niña and the Indian Ocean Dipole — are fueling the flooding. Both occur naturally and are influenced by warmer ocean temperatures.  They are dumping above-average rainfall across much of Australia, and experts say they are being super-charged by climate change.

Sydney is having its wettest year on record. More than 2 meters of rain have fallen on Australia’s biggest city, breaking the previous record set in 1950.

Europe faces a higher-than-usual chance of a cold blast of weather before the end of the year, but the winter overall is likely to be warmer than average, the continent’s long-range weather forecaster said Thursday.

Temperatures this winter will be crucial for homeowners worried about the record cost of heating their homes, and for European policymakers seeking to avoid energy rationing because of reductions in Russian gas supplies.

“We see the winter as being warmer than usual,” said Carlo Buontempo, director of the Copernicus Climate Change Service that produces seasonal forecasts for the European Center for Medium-Range Weather Forecasts (ECMWF).

“Nevertheless, there is a still a significant chance of a block situation, which can lead to cold temperatures and low wind over Europe,” he told AFP as the service issued a monthly update to its forecasts.

A so-called block or blocking pattern in the winter can bring stable, often wind-free weather accompanied by freezing temperatures.

“This was looking more likely in November, but there now looks like a pronounced probability of a cold outbreak in December,” Buontempo added.

The ECMWF produces weather modelling with data from a range of national weather services around Europe.

Its forecasts are based on indicators such as ocean and atmospheric temperatures, as well as wind speeds in the stratosphere, but do not have the accuracy of short-range reports.

The models provide the “best information possible, to give a hint, to guide our decisions,” Buontempo said.

The European winter was expected to be warmer than usual because of the La Nina global weather phenomenon, which is related to cooling surface temperatures in the central and eastern equatorial Pacific Ocean.

“We know that in a La Nina year, the latter part of the European winter tends to favor westerly winds, so warm and wet,” Buontempo said.

The agency will update its winter season forecast next month when it will have greater confidence because “all the drivers for the winter will be more active,” he said.

Independent energy experts expect Europe to be able to withstand Russia’s gas cuts this winter, providing temperatures stay in line with or above the long-term average.

Governments have almost filled their strategic gas reserves and consumers are being urged to reduce their consumption.

The International Energy Agency, a Paris-based energy consultancy, believes that temperatures about 10% below average over the winter would put strain on the European gas system.

It has also said a late cold spell, when gas stocks are expected to be low, could be the “Achilles heel of European gas supply security.”

A monkeypox outbreak has been confirmed in the town of Mbonge, health authorities in Cameroon say, but armed separatists are preventing workers from investigating suspected cases.

Cameroon government officials say health workers have been deployed to the districts of Kumba and Mbonge to communicate to hundreds of civilians with suspected monkeypox infections to immediately isolate and avoid contact with other people and animals, including pets. 

Kumba and Mbonge are districts located in Cameroon’s English-speaking southwest region near the border with Nigeria. 

Emmanuel Lenya Nefenda, the highest ranking Cameroon public health official in Kumba, said civilians are being educated after a suspected monkeypox infection was confirmed in Kumba. He said the case was reported after the confirmation by Cameroon public health officials of a monkeypox outbreak in Bole Bakundu, a village in Mbonge. 

In order to prevent the spread of the highly contagious monkeypox, Nefenda said people should avoid contact with wild animals, avoid eating wild animals, and wear clean clothes, as opposed to “bush clothes” that may have had contact with rats or other animals.

Nefenda spoke from Kumba via the messaging app WhatsApp. 

The government says one case of monkeypox was confirmed in Kumba, and the patient is receiving treatment in a hospital isolation ward. Several dozen specimens have been collected from suspected patients and sent to specialized laboratories in Cameroon’s capital, Yaounde, for laboratory examinations. 

Health officials are warning civilians to take suspected patients to hospitals, and not to herbalists or African traditional healers in villages. But villagers say ongoing battles between separatists and government troops make it impossible for suspected patients to be transported to hospitals, which are far from towns. 

Separatists on social media platforms, including Facebook and WhatsApp, say any health worker sent by Cameroon’s central government in Yaounde should obtain an authorization from fighters. 

But the government says only Cameroon state officials can assure the safety of health workers assisting people suspected of monkeypox infections. 

Eko Eko Filbert, the highest government official in charge of public health in Cameroon’s English-speaking Southwest region where Kumba and Mbonge are located, said armed groups should allow medical staff members to render humanitarian services. 

Monkeypox is contagious, he said, but can be contained with the help of health workers.

Eko said no health official deployed to assist civilians suspected of monkeypox infection has been attacked, but that frightened health workers are scared of going out to search for patients and suspected patients. 

The government says it will protect both its citizens and health workers. 

The U.N. says Cameroon is a monkeypox endemic country but displacement away from established surveillance systems due to armed conflicts increase the risk of undetected transmission. 

On Wednesday, the World Health Organization said 21 countries in the past week reported an increase in monkeypox cases, mostly in the Americas, which accounted for almost 90% of all cases reported last week. 

The WHO says cases in the global monkeypox outbreak have topped 70,000 and warned that a decline in new cases does not mean people should drop their guard, as the slowdown in new cases worldwide could be the most dangerous time in the outbreak.

The U.N. says the disease causes fever, muscular aches and large boil-like skin lesions.

Taiwan lifted all its COVID-19 entry restrictions Thursday, allowing tourists unfettered access to the self-ruled island after more than 2 1/2 years of border controls.

Hong Kong and Taiwan, together with mainland China, required most visitors to complete a mandatory quarantine period throughout the pandemic, even as most countries reopened their borders to tourists.

Visitors are no longer required to quarantine upon entry, or take any PCR tests. Instead, they will need to monitor their health for a week after arriving, and obtain a negative result on a rapid antigen test the day they arrive. If people want to go out during the weeklong monitoring period, they need a negative test from either that day or the day before.

There are also no longer any restrictions on certain nationalities being allowed to enter Taiwan.

Dozens of visitors from Thailand were among the first to arrive under the new rules at Taiwan’s Taoyuan International Airport, which serves the capital Taipei, on a Tiger Air flight that landed shortly after midnight.

Tourists like 32-year-old Mac Chientachakul and his parents were excited to visit the island.

“Hot pot is my favorite dish in Taiwan,” Chientachakul said. “It’s my first thing to do … I miss it so much.”

Sonia Chang, a travel agent, said the changes are good for both the tourism industry and Taiwanese residents, who can now travel abroad without having to quarantine when they get home.

Valaisurang Bhaedhayajibh, a 53-year-old business development director of a design firm, called the new rules convenient.

“We don’t have to do the test before coming here, and also after arriving,” he said. “We are still required to do the self-test every two days, and everything has been provided” by Taiwanese authorities, including the rapid testing kits.

At a welcome ceremony in the Taoyuan airport’s arrival hall, the travelers from Thailand were met by the Taiwan Tourism Bureau’s director, Chang Shi-chung, who handed out gifts.

Taiwan’s tourism bureau estimated that a total of 244 tourists from some 20 tour groups will arrive Thursday.

With both Hong Kong and Taiwan getting rid of restrictions and welcoming back tourists, mainland China remains one of the few places in the world adamant in keeping borders closed and sticking to a “zero-COVID” strategy to stamp out the virus. Hong Kong ended its mandatory quarantine policy for inbound travelers late last month, requiring just a three-day self-monitoring period.
