Brazil’s government has declared a public health emergency for the Yanomami people in the Amazon who are suffering from malnutrition and diseases such as malaria because of illegal mining.

The decree, signed by Health Minister Nisia Trindade on Friday, has no expiration date and allows for hiring extra personnel. It determines that the team in charge has to publish reports regarding the Indigenous group’s health and general well-being.

President Luiz Inacio Lula da Silva also created a multiministerial committee to be coordinated by his chief of staff for an initial period of 90 days. He is traveling to Roraima state’s capital, Boa Vista, where many ill Yanomami have been admitted to specialized hospitals.

The Yanomami are the largest native group in Brazil, with a population of around 30,000 that lives in an area larger than 9 million hectares (22 million acres) in the northern area of the Amazon rainforest, close to the border with Venezuela.

In recent years, specialists sounded the alarm that humanitarian and sanitary crises were taking shape. The report “Yanomami Under Attack,” written by the nonprofit Socio-Environmental Institute, points out that in 2021 the region was responsible for 50% of the malaria cases in the country. The same report said that more than 3,000 children were malnourished.

Illegal mining is the main root of the problems faced by the Yanomami people. Activists accuse miners of death threats, sexual violence and alcohol and drug abuse, especially against Indigenous children. The same report shows that the region had more than 40 illegal airstrips made by miners and that they had taken over some of the government health centers installed in the region.

Earlier this week, the Health Ministry had already designated a team for a special health mission in the Yanomami region. Lula scheduled an emergency trip to Roraima state following a report by independent local news website Sumauma, featuring shocking pictures of malnourished children.

According to the report, during the last four years of former President Jair Bolsonaro’s government, the death of children aged 5 or less had jumped 29% in comparison to the previous government. The same report shows that 570 Yanomami children died between 2019 and 2022 from curable diseases.

Lula tweeted that the government received information on the “absurd situation” of malnourishment in Yanomami children. The president will be accompanied by several of his ministers in Boa Vista.

Tons of waste dumped in poorly regulated riverside landfills or directly into the waterways that flow across three countries end up accumulating behind a trash barrier in the Drina River in eastern Bosnia during the wet weather of winter and early spring.

This week, the barrier once again became the outer edge of a massive floating waste dump crammed with plastic bottles, rusty barrels, used tires, household appliances, driftwood and other garbage picked up by the river from its tributaries.

The river fencing installed by a Bosnian hydroelectric plant, a few kilometers upstream from its dam near Visegrad, has turned the city into an unwilling regional waste site, local environmental activists complain.

Heavy rain and unseasonably warm weather over the past week have caused many rivers and streams in Bosnia, Serbia and Montenegro to overflow, flooding the surrounding areas and forcing scores of people from their homes. Temperatures dropped in many areas Friday as rain turned into snow.

“We had a lot of rainfall and torrential floods in recent days and a huge inflow of water from (the Drina’s tributaries in) Montenegro which is now, fortunately, subsiding,” said Dejan Furtula of the environmental group Eko Centar Visegrad.

“Unfortunately, the huge inflow of garbage has not ceased,” he added.

The Drina

The Drina River runs 346 kilometers (215 miles) from the mountains of northwestern Montenegro through Serbia and Bosnia. and some of its tributaries are known for their emerald color and breathtaking scenery. A section along the border between Bosnia and Serbia is popular with river rafters when it’s not “garbage season.”

Some 10,000 cubic meters (more than 353,000 cubic feet) of waste are estimated to have amassed behind the Drina River trash barrier in recent days, Furtula said. The same amount was pulled in recent years from that area of the river.

Removing the garbage takes up to six months, on average. It ends up at the municipal landfill in Visegrad, which Furtula said “does not even have sufficient capacity to handle (the city’s) municipal waste.”

“The fires on the (municipal) landfill site are always burning,” he said, calling the conditions there “not just a huge environmental and health hazard, but also a big embarrassment for all of us.”

Environmental woes

Decades after the devastating 1990s wars that accompanied the breakup of Yugoslavia, the Balkans lag behind the rest of Europe both economically and with regard to environmental protection.

The countries of the region have made little progress in building effective, environmentally sound trash disposal systems despite seeking membership in the European Union and adopting some of the EU’s laws and regulations.

Unauthorized waste dumps dot hills and valleys throughout the region, while trash litters roads and plastic bags hang from the trees.

In addition to river pollution, many countries in the western Balkans have other environmental woes. One of the most pressing is the extremely high level of air pollution affecting several cities in the region.

“People need to wake up to problems like this,” Visegrad resident Rados Brekalovic said.

As damaging as it was for more than 32 trillion gallons of rain and snow to fall on California since Christmas, a worst-case global warming scenario could juice up similar future downpours by one-third by the middle of this century, a new study says.

The strongest of California’s storms from atmospheric rivers, long and wide plumes of moisture that form over an ocean and flow through the sky over land, would probably get an overall 34% increase in total precipitation, or another 11 trillion gallons more than just fell. That’s because the rain and snow is likely to be 22% more concentrated at its peak in places that get really doused, and to fall over a considerably larger area if fossil fuel emissions grow uncontrolled, according to a new study in Thursday’s journal Nature Climate Change.

The entire western United States would likely see a 31% increase in precipitation from these worst of the worst storms in a souped-up warming world because of more intense and widely spread rainfall, the study said.

Scientists say the worst-case scenario, which is about 4.4 degrees Celsius (7.9 degrees Fahrenheit) of warming since pre-industrial times, looks a bit more unlikely since efforts are being undertaken to rein in emissions. If countries do as they promise, temperatures are on track to warm about 2.7 degrees Celsius (4.9 degrees Fahrenheit), according to Climate Action Tracker.

The National Weather Service calculated that California averaged 11.47 inches of precipitation statewide from Dec. 26 to Jan. 17 — including 18.33 inches in Oakland and 47.74 inches in one spot 235 miles north of San Francisco — because of a series of nine devastating atmospheric rivers that caused power outages, flooding, levee breaks, washouts and landslides. At least 20 people died.

“It could be even worse,” said study author Ruby Leung, a climate scientist at the U.S. Pacific Northwest National Lab. “We need to start planning how would we be able to deal with this.”

Leung used regional scale computer simulations to predict what the worst of the western winter storms will be like between 2040 and 2070 in a scenario where carbon emissions have run amok. She looked at total precipitation, how concentrated peak raining and snowing would be and the area that gets hit. All three factors grow for the West in general. California is predicted to get the highest increase in peak precipitation, while the Southwest is likely to see more rain because of a big jump in area of rainfall. The Pacific Northwest would see the least juicing of the three areas.

Overall precipitation is a bit lessened from adding all the factors, because just as the peak rainfall grows the rainfall on the edges of the storms is predicted to weaken, according to the study.

There are two types of storms that Leung said she worries about: Flash floods from intense rain concentrated over a small area and slower, larger floods that occur from rain and snow piling up over a large area. Both are bad, but the flash floods cause more damage and hurt people more, she said.

And those flash floods are likely to get worse from what Leung’s paper calls a “sharpening” effect that happens in an ever warmer world. That means more rainfall concentrated in the central areas of storms, falling at higher rates per hour, while at the outer edges rainfall is a bit weaker.

This happens because of the physics of rain storms, Leung said.

Not only can the atmosphere hold 4% more moisture per degree Fahrenheit (7% per degree Celsius), but it’s what happens in the storm that changes and makes the precipitation come down even more, Leung said. You’ve got air rising inside the storm with more water vapor condensing to produce rain and snow; it then releases heat “that kind of causes the storm to become more vigorous and stronger,” she said.

When water vapor condenses it comes down as rain and snow along the edges of the storm, but heating sort of squeezes that falling precipitation in toward the middle, Leung said.

“The concepts and impacts of how precipitation features are likely to change are well quantified and well explained,” said David Gochis, an expert in how water affects the weather at the National Center for Atmospheric Research in Boulder, Colorado, who wasn’t part of the study.

When she used computer simulations, Leung chose the most severe worst-case scenario for how the world’s carbon emissions will grow. It’s a scenario that used to be called business as usual, but the world is no longer on that track. After years of climate negotiations and the growth of renewable fuels the globe is heading to less warming than the worst case, according to climate scientist Zeke Hausfather of the tech company Stripe and Berkeley Earth.

“We are providing more of a worst-case scenario, but understanding that if we do take action to reduce emissions in the future, we could end up better,” Leung said. “If we control the emissions and lower the global warming in the future, we can limit the impacts of climate change on the society, particularly flooding and extreme precipitation that we are talking about in this study.”

Countless artists have taken inspiration from “The Starry Night” since Vincent Van Gogh painted the swirling scene in 1889.

Now artificial intelligence systems are doing the same, training themselves on a vast collection of digitized artworks to produce new images you can conjure in seconds from a smartphone app.

The images generated by tools such as DALL-E, Midjourney and Stable Diffusion can be weird and otherworldly but also increasingly realistic and customizable — ask for a “peacock owl in the style of Van Gogh” and they can churn out something that might look similar to what you imagined.

But while Van Gogh and other long-dead master painters aren’t complaining, some living artists and photographers are starting to fight back against the AI software companies creating images derived from their works.

Two new lawsuits —- one this week from the Seattle-based photography giant Getty Images —- take aim at popular image-generating services for allegedly copying and processing millions of copyright-protected images without a license.

Getty said it has begun legal proceedings in the High Court of Justice in London against Stability AI — the maker of Stable Diffusion —- for infringing intellectual property rights to benefit the London-based startup’s commercial interests.

Another lawsuit filed Friday in a U.S. federal court in San Francisco describes AI image-generators as “21st-century collage tools that violate the rights of millions of artists.” The lawsuit, filed by three working artists on behalf of others like them, also names Stability AI as a defendant, along with San Francisco-based image-generator startup Midjourney, and the online gallery DeviantArt.

The lawsuit said AI-generated images “compete in the marketplace with the original images. Until now, when a purchaser seeks a new image ‘in the style’ of a given artist, they must pay to commission or license an original image from that artist.”

Companies that provide image-generating services typically charge users a fee. After a free trial of Midjourney through the chatting app Discord, for instance, users must buy a subscription that starts at $10 per month or up to $600 a year for corporate memberships. The startup OpenAI also charges for use of its DALL-E image generator, and StabilityAI offers a paid service called DreamStudio.

Stability AI said in a statement that “Anyone that believes that this isn’t fair use does not understand the technology and misunderstands the law.”

In a December interview with The Associated Press, before the lawsuits were filed, Midjourney CEO David Holz described his image-making subscription service as “kind of like a search engine” pulling in a wide swath of images from across the internet. He compared copyright concerns about the technology with how such laws have adapted to human creativity.

“Can a person look at somebody else’s picture and learn from it and make a similar picture?” Holz said. “Obviously, it’s allowed for people and if it wasn’t, then it would destroy the whole professional art industry, probably the nonprofessional industry too. To the extent that AIs are learning like people, it’s sort of the same thing and if the images come out differently then it seems like it’s fine.”

The copyright disputes mark the beginning of a backlash against a new generation of impressive tools — some of them introduced just last year — that can generate new images, readable text and computer code on command.

They also raise broader concerns about the propensity of AI tools to amplify misinformation or cause other harm. For AI image generators, that includes the creation of nonconsensual sexual imagery.

Some systems produce photorealistic images that can be impossible to trace, making it difficult to tell the difference between what’s real and what’s AI. And while most have some safeguards in place to block offensive or harmful content, experts say it’s not enough and fear it’s only a matter of time until people utilize these tools to spread disinformation and further erode public trust.

“Once we lose this capability of telling what’s real and what’s fake, everything will suddenly become fake because you lose confidence of anything and everything,” said Wael Abd-Almageed, a professor of electrical and computer engineering at the University of Southern California.

As a test, The Associated Press submitted a text prompt on Stable Diffusion featuring the keywords “Ukraine war” and “Getty Images.” The tool created photo-like images of soldiers in combat with warped faces and hands, pointing and carrying guns. Some of the images also featured the Getty watermark, but with garbled text.

AI can also get things wrong, like feet and fingers or details on ears that can sometimes give away that they’re not real, but there’s no set pattern to look out for. And those visual clues can also be edited. On Midjourney, for instance, users often post on the Discord chat asking for advice on how to fix distorted faces and hands.

With some generated images traveling on social networks and potentially going viral, they can be challenging to debunk since they can’t be traced back to a specific tool or data source, according to Chirag Shah, a professor at the Information School at the University of Washington, who uses these tools for research.

“You could make some guesses if you have enough experience working with these tools,” Shah said. “But beyond that, there is no easy or scientific way to really do this.”

But for all the backlash, there are many people who embrace the new AI tools and the creativity they unleash. Searches on Midjourney, for instance, show curious users are using the tool as a hobby to create intricate landscapes, portraits and art.

There’s plenty of room for fear, but “what can else can we do with them?” asked the artist Refik Anadol this week at the World Economic Forum in Davos, Switzerland, where he displayed an exhibit of his AI-generated work.

At the Museum of Modern Art in New York, Anadol designed “Unsupervised,” which draws from artworks in the museum’s prestigious collection — including “The Starry Night” — and feeds them into a massive digital installation generating animations of mesmerizing colors and shapes in the museum lobby.

The installation is “constantly changing, evolving and dreaming 138,000 old artworks at MoMA’s Archive,” Anadol said. “From Van Gogh to Picasso to Kandinsky, incredible, inspiring artists who defined and pioneered different techniques exist in this artwork, in this AI dream world.”

For painters like Erin Hanson, whose impressionist landscapes are so popular and easy to find online that she has seen their influence in AI-produced visuals, she is not worried about her own prolific output, which makes $3 million a year.

She does, however, worry about the art community as a whole.

“The original artist needs to be acknowledged in some way or compensated,” Hanson said. “That’s what copyright laws are all about. And if artists aren’t acknowledged, then it’s going to make it hard for artists to make a living in the future.”
