Sloths, the famously slow-moving yet adorable creatures native to Central and South America, could face extinction by the end of the century due to climate change.

Researchers investigating how sloths respond to rising temperatures have found that the animals' slow metabolism and limited ability to regulate body temperature may leave them unable to survive in a warming world—especially for populations living in high-altitude regions.

"Despite being iconic species, comprehensive long-term population monitoring simply hasn't been conducted at a scale that reflects the true challenges sloths face," lead researcher Rebecca Cliffe told Newsweek. "However, from our 15 years of working with sloths in Costa Rica, we are very concerned. In areas where sloths were once abundant, we have observed their populations completely disappear over the past decade."

The study, published in PeerJ Life & Environment, focused on two-fingered sloths inhabiting both lowland and highland environments in Costa Rica.

"Sloths are uniquely vulnerable to rising temperatures due to their physiological adaptations," Cliffe said. "They survive on an extremely low-calorie diet, so conserving energy is critical for them.

"One key way they do this is by not actively regulating their body temperature like most mammals do—temperature regulation is an energy-intensive process."

A major concern is that sloths' slow digestion rates—up to 24 times slower than similar-sized herbivores—make it difficult for them to increase food intake to meet rising metabolic demands.

This slow metabolic rate, combined with their minimal energy-processing capacity, means that sloths cannot easily balance the increased energy requirements brought on by higher temperatures.

“Texas has this sort-of macho heat thing, that we’re ‘Texas tough’ and we’re not going to let a little heat stop us. Heat builds character and sweat is how you get tough,” Jeff Goodell said, adding that such attitudes are “really dangerous.”

The report by the Potsdam Institute for Climate Impact Research (PIK) details nine factors that are crucial for regulating the planet's ability to sustain life.

In six of these areas, the safe limit has already been exceeded in recent years as a result of human activity.

The crucial threshold for ocean acidification could soon become the seventh to be breached, according to the PIK's first Planetary Health Check.

The safe boundaries that have already been crossed concern crucial -- and related -- factors including climate change; the loss of natural species, natural habitat and freshwater; and a rise in pollutants, including plastics and chemical fertilisers used in agriculture.

"As CO2 emissions increase, more of it dissolves in sea water... making the oceans more acidic," Boris Sakschewski, one of the lead authors, told reporters.

"Even with rapid emission cuts, some level of continued acidification may be unavoidable due to the CO2 already emitted and the time it takes for the ocean system to respond," he explained.

"Therefore, breaching the ocean acidification boundary appears inevitable within the coming years."

Rafaela Drumond death a police officer in June 2023 was bullied relentlessly by her colleagues, was one of 152 suicides among Brazilian law enforcement agents last year, the highest number on record and a 13.4% increase from 2022, according to a new report released on Thursday.

“The number of public security officers who commit or attempt suicide is steadily rising,” says the report, produced by the Institute for Research, Prevention, and Studies on Suicide (IPPES) and the Public Labour Prosecution Office.

Among last year’s deaths, 9% were women – slightly below the proportion of female officers in the forces, which ranges from 12% to 16%. Twelve men and two women killed their wives, partners or exes before taking their own lives. Three of the murdered women had protective orders against their killers.

According to the researchers, the phenomenon is underreported, as some forces still refuse to share their statistics.

• A total of 2 million hectares (5 million acres) of forests, wetlands and grasslands will be razed to make way for a cluster of giant sugarcane plantations.

• And much of the sugar produced from the Merauke project won’t even be used for food. The government plans to develop sugarcane-derived bioethanol as part of its transition away from fossil fuels.

• Satellite imagery analysis shows that 30% of the concessions appear to fall inside a zone that the government previously declared should be protected under a moratorium program.

• A similar megaproject in Merauke, the Merauke Integrated Food and Energy Estate (MIFEE), initiated by Jokowi’s predecessor turned out to be a failure, used as cover to establish oil palm and pulpwood plantations instead.

Central Europe's devastating floods were made much worse by climate change and offer a stark glimpse of the future for the world's fastest-warming continent, scientists say.

Storm Boris has ravaged countries including Poland, the Czech Republic, Romania, Austria and Italy, leading to at least 24 deaths and billions of pounds of damage.

The World Weather Attribution (WWA) group said one recent four-day period was the rainiest ever recorded in central Europe - an intensity made twice as likely by climate change.

One reason Boris has produced so much rain is that the weather system got 'stuck', dumping huge amounts of water over the same areas for days.

There is some evidence that the effects of climate change on the jet stream - a band of fast-flowing winds high up in the atmosphere - may make this 'stalling' phenomenon more common. But this is still up for debate.

Even if we don't get more 'stalled' weather systems in the future, climate change means that any that do get stuck can carry more moisture and therefore be potentially disastrous.

“The [severity of the] flood events is going to increase considerably in the future, so if you keep the flood protections at the same level as they are today, the impacts may become unbearable for societies in Europe,” explains Francesco Dottori of IUSS in Pavia, Italy.

One day, Wayland will truly take over the Linux world, but it's not quite there yet with plenty still using X11 due to various problems some of which the new Frog Protocols aim to solve.

Announced by misyl, who does various work for Valve (like Gamescope), it certainly sounds like a good idea to give Wayland Protocols a swift kick to get into gear to improve things for users. Writing on their social media post :

Wayland Protocols has long had a problem with new protocols sitting for months, to years at a time for even basic functionality.

This is hugely problematic when some protocols implement very primitive and basic functionality such as frog-fifo-v1, which is needed for VSync to not cause GPU starvation under Wayland and also fix the dreaded application freezing when windows are occluded with FIFO/VSync enabled.

We need to get protocols into end-users hands quicker! The main reason many users are still using X11 is because of missing functionality that we can be shipping today, but is blocked for one reason or another.

The Amazon rainforest has lost an area about the size of Germany and France combined to deforestation in four decades, fueling drought and record wildfires across South America, experts said Monday.

The world's biggest jungle, spanning nine countries, is crucial to the fight against climate change due to its ability to absorb planet-warming carbon dioxide from the atmosphere.

However, researchers say a record spate of wildfires this year has instead released massive amounts of carbon dioxide back into the atmosphere.

Various scientific reports have laid out the grim links between forest loss and a changing climate and the devastation that can follow for humans and wildlife.

Deforestation, mainly for mining and agricultural purposes, has led to the loss of 12.5 percent of the Amazon's plant cover from 1985 to 2023, according to RAISG, a collective of researchers and NGOs.

This amounts to 88 million hectares (880,000 square kilometers, 339,773 square miles) of forest cover lost across Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, Suriname and French Guiana.

Typhoid, also known as enteric fever, is an infection caused by contaminated food or water. If left untreated, it kills one in five. But the cure is a simple course of antibiotics. Most people, if they get the drugs promptly, should start recovering within a few days.

But the antibiotics used to cure typhoid are now failing. The bacteria, Salmonella typhi, have developed resistance to the antibiotics meant to kill them. It’s a pattern repeated across the world; the problem of resistant infections is global and borderless. And children across the village – on the outskirts of Peshawar, northern Pakistan – had been falling ill.

The hospital was rammed. On the children’s ward, each single bed held four or five patients.

“Typhoid was once treatable with a set of pills and now ends up with patients in hospital,” says Jehan Zeb Khan, the clinical pharmacist at the hospital.

Infection was caused by extensively drug resistant (XDR) typhoid – a strain of “superbug” that emerged in Pakistan in 2016. XDR-typhoid is resistant to almost all of the antibiotics that are supposed to treat the disease, so options are limited and death rates are higher.

South Korea is projected to see its population drop significantly over the next 50 years, and its global population ranking fall by 30 notches over the ultra-low birth rate and rapid aging, data showed Monday.

The country's population is projected to come to 36 million in 2072, down 30.8 percent from this year's 52 million. Its population peaked in 2020 and has been on a decline, according to the data by Statistics Korea.

The world population, however, is forecast to continue to rise during the cited period to reach 10.22 billion in 2072, compared with an estimated 8.16 billion this year.

South Korea was the world's 29th most populous country in 2024, but the ranking is expected to fall to 59 in the 2072, the agency said.
