Western Sahara is the largest disputed territory in the world, designated by the United Nations as a non-self-governing territory, despite Morocco controlling about 80% of it.

San Sebastián, the capital of La Gomera, served as Christopher Columbus's provisioning point in 1492, with historical sites like the Columbus House Museum and Torre del Conde nearby.

The Wasteland Nomad is built from biochar and seeds of indigenous plants, which are both biodegradable materials. Biochar works like a sponge inside the soil, as it holds water, gives microbes a surface to live on, and locks carbon into the ground instead of letting it escape into the air.

Before state Route 62 was built, there was seamless 95-mile-long habitat connectivity between the San Bernardino and Little San Bernardino mountain ranges, extending from the I-10 south of Joshua Tree National Park to the I-15 near the Cajon Pass. Now, plans for two new wildlife crossings across the highway aim to bring back some of that connectivity, while potentially saving a local population on the brink of extinction in the process.

In Turkana, the land is rugged, roads disappear into dust, and villages are scattered across vast distances in a county of just more than a million people. Despite it being the rainy season, weather experts warn that Turkana and other arid regions may receive little relief. Authorities say drought is once again taking place, with 23 of Kenya's 47 counties affected.

For 2025, there was good news and bad news: overall, these areas were visited 323 million times over the course of the year. That's the good news; the bad news is that this figure was down ever so slightly - specifically, 2.7% - from a record-setting 2024.

The Colorado River is an interconnected system, sustained by Rocky Mountain snowpack, rainfall and groundwater. It is fragile, and under increasing stress. Two and a half decades into this century, the river that built the modern West has 20% less water flowing through it than it did on average in the last century. As heat and drought intensify, so do the stakes: Failure to recognize the severity of changing conditions, managing the river in parts without considering needs of the whole and inadequate planning for long-term shortages put the future of all the basin at risk.

An unnamed tourist saw it and told Aidan Moore, who works for Alcatraz City Cruises. Moore told SFGATE that he was initially skeptical, but the guest's iPhone footage left little room for doubt. The video shows, not a sea lion or an otter, but an actual Canis latrans, doggedly dogpaddling, then clambering out of the water, noticeably shaky and struggling to settle tired paws on the craggy rocks.

As a SoCal resident, I visit Anza-Borrego at least once a year to explore the sandstone Slot canyon and surrounding desert, keeping an eye out for animals like chuckwalla lizards and bighorn sheep. Despite its incredibly dry environment (the park averages just four to eight inches of rain a year, and summertime temps routinely hit the hundreds), Anza-Borrego teems with life and opportunities to explore one of the nation's most unique ecosystems.

Because we're homeotherms, we assume all mammals work the way we do. But in recent years, as improvements in technology allowed researchers to more easily track small animals and their metabolisms in the wild, we're starting to find a lot more weirdness.

Over time, the water evaporated to form the smaller, brinier Owens Lake. Indigenous Paiute people call the Owens Valley Payahuunadü, 'the land of the flowing water'. Today, Owens Lake is a 'Dusty Vestige of the Old West', as NASA described a photograph of the lake taken from space.

To capture the biological impact of this extreme environment, I used a comprehensive suite of sensors and biomarker analyses. I wore a wireless electroencephalograph (EEG) system to monitor brain activity, sleep stages and neural signatures of stress and adaptation; the Oura Ring to continuously track sleep patterns, heart-rate variability and circadian-rhythm shifts; and the glucose monitor to follow metabolic responses in real time.

The most beautiful places in Oman are diverse, stark, and staggering. With ancient ruins, fragrant souks, and picturesque mountain villages, there is no shortage of man-made wonders. But it is the country's geology that delights best. In this desert nation, beauty is defined by water: the white sands of surf-battered beaches, gurgling wadi streams, and cloud-shrouded massifs where pomegranates hang heavy.

Western water law is based on the prior appropriation doctrine, which gives the first entity to make "beneficial use" of water the right to keep on using that amount, even if that means that upstream "junior" users' spigots will get shut off. By the early 1900s, a rapidly growing California was enthusiastically diverting the Colorado River, with huge irrigation districts gobbling up the senior water rights.

A global research team has analyzed the prospects for biomineralization on Mars, a process in which bacteria, fungi, and microalgae can create minerals as part of their metabolism, offering a byproduct that could be useful to prospective Martian explorers by providing the raw materials needed to produce aggregates such as concrete. With an extremely thin and mostly carbon dioxide atmosphere, air pressure less than 1 percent of Earth's,

Wildlife populations are in decline. Recreation sites are crowded and often underfunded. Wildfires are larger, more destructive and harder to control. Climate change is reshaping natural systems, from ocean fisheries to mountain snowpacks, faster than institutions can respond. At the same time, communities are being asked to host new energy projects, transmission lines and mineral development - often without clear processes, adequate resources or trust that decisions are being made in the public interest.

The body is a shifting landscape transformed by surfaces and sensations. Each look captures a different tactile world: the heat of blood, the cool weight of metal, the yielding drift of water. The result is a sculptural study of how the elements carve, shield, and release the self. The materials we embody become the emotions we carry, and the body becomes a materialised exhibition of our emotions, from the pulse of Blood to the discipline of Metal to the surrender of Water.

Researchers have discovered the naturally mummified and skeletal remains of 61 cheetahs, which were hidden deep inside caves in northern Saudi Arabia for hundreds, and in some cases thousands, of years. The find indicates that these big cats roamed the Arabian Peninsula for millennia before they disappeared from the landscape between 49 and 188 years agoevidence that bolsters an effort to rewild the region with modern-day cheetahs, according to Ahmed Boug, general director of the National Center for Wildlife in Riyadh.

In the pristine High Arctic sits the Kitsissut island cluster, also known as the Carey Islands, nestled between northwest Greenland and northeast Canada. The surrounding seas are perilous, and traveling there is difficult even with modern boats. But new archaeological evidence suggests ancient humans managed to sail to the islands, too. Early settlers lived on the islands between 4,500 and 2,700 years ago.

Each city was scored across five weighted factors using publicly available data sources: average winter temperatures (NOAA), trail accessibility, average number of reviews, average trail ratings (AllTrails), and the number of campgrounds in the state (Camping USA). After looking at all the available information, Extreme Terrain named Tucson as the No. 1 destination for a nature getaway this winter. According to the findings, it won out thanks to its "excellent trail access and highly rated hikes."

After experiencing one of the wettest holiday seasons on record, still soggy California hit a major milestone this week - having zero areas of abnormal dryness for the first time in 25 years. This data, collected by the U.S. Drought Monitor, is a welcome nugget of news for Golden State residents, who in the last 15 years alone have lived through two of the worst droughts on record, the worst wildfire seasons on record and the most destructive wildfires ever.

It was a race against nightfall. As he hurried across the sandy, bristling landscape of California's Carrizo Plain, ecologist Ian Axsom stopped every 10 yards to place an aluminum live trap on the ground, eventually distributing traps over an area the size of two baseball fields. Against the rolling playas and tawny mountains, the traps glinted with golden remnants of the September dusk.

If they survived the summer and reached adulthood, they would become some of the fastest land animals on Earth. Adult pronghorn, a bit smaller than deer, can run seven miles in just 10 minutes, achieving short bursts of nearly 60 mph, much faster than horses or wolves. With their long thin legs and oversized hearts and lungs, they are built to cover ground in the wide-open sagebrush basins of Wyoming, my home state.

In the small town of Chipaya, everything is dry. Only a few people walk along the sandy streets, and many houses look abandoned some secured with a padlock. The wind is so strong that it forces you to close your eyes. Chipaya lies on Bolivia's Altiplano, 35 miles from the Chilean border. The vast plateau, nearly 4,000 metres above sea level, feels almost empty of people and animals, its solitude framed by snow-capped volcanoes. It raises the question: can anybody possibly live here?

When the category-5 storm Hurricane Melissa struck Jamaica in October, its path crossed communities that had varying levels of preparedness. Many with maintained coastal protections, upgraded drainage and reliable early-warning systems had power and water restored in days. Others were immobilized for weeks.

Polar bears are the poster children of climate changeand for good reason. These giant bears hunt, mate and spend their days hanging out on Arctic sea ice, which is rapidly disappearing as the climate warms. But some polar bears, it seems, are far more resilient than we realized: new research suggests that in one region, the bears are adapting to the declining sea ice.
