Seawater surges into low-lying communities from San Diego to San Francisco Bay Area, submerging streets, homes and businesses

Historic high tides have caused chaos up and down the California coast this week, as parts of the state were inundated by record-breaking water levels. Seawater surged into low-lying communities from San Diego to the San Francisco Bay Area, submerging streets, flooding homes and businesses, and jamming important transportation corridors and train routes.

Kayakers and paddle boarders could be seen gliding through typically busy thoroughfares in Marin county, north of San Francisco, on Monday and Tuesday. Several drivers had to be rescued from floating cars in the area, while cyclists who had attempted to cross the temporary lagoon that had formed quickly found themselves waist-deep. Further south, in cities such as Newport Beach, water pounded the emergency infrastructure set up to keep out the swelling sea, which seeped through berms, seawalls and sandbag blockades along the shoreline.

President has taken an axe to National Oceanic and Atmospheric Administration, stalling climate research on and response to extreme weather events

Sweeping cuts to the premier US climate agency under Donald Trump have severely hampered the country’s capacity to forecast, research and respond to extreme weather events, former government officials and scientists have warned, as the US faces a cascade of hazards fueled by a potentially historic El Niño this winter.

From the start of his second term, the president has taken aim at the National Oceanic and Atmospheric Administration (Noaa), slashing staff levels, canceling contracts and grants, and shutting down databases and research laboratories. The agency that has long been considered a global crown jewel in climate science and forecasting has lost roughly 20% of its staff since January 2025.

A modern-day prospector promised rural Imperial thousands of jobs and millions in tax revenue – but his plan has set off a firestorm of resistance

Sebastian Rucci zoomed in on a map in late 2024, looking closely at a large block of brown earth. The barren plot sandwiched between sprawling alfalfa fields and sleepy desert suburbs was exactly what he’d been searching for – the perfect place to realize his dream of building the largest artificial intelligence datacenter in California.

The dusty expanse wasn’t an obvious location. It was in the Sonoran desert, just north of the Mexican border, where temperatures regularly rose past 100F (37.8C). Water was scarce in the once-booming agricultural area, which gets its supply from the beleaguered Colorado River. And then, there was the city of Imperial – population 22,000 – to win over. As controversial datacenter projects have sprung up across the US, residents were naturally skeptical of a new, energy-guzzling neighbor.

Kaylub Giamanco, who was reportedly driving home when he heard gunshots, ‘not seeking recognition’, family says

Details are beginning to emerge about Kaylub Giamanco, the man who brought the deadly shooting at elementary school in Bend, Oregon on Thursday, to an end by fatally shooting the 16-year-old suspect in the midst of a violent rampage.

While police have declined to release the man’s identity, Giamanco’s family issued a statement on Friday confirming that he shot and killed the suspect, identified Friday as Griffin J John II, a former Silver Rail student.

The remains of Edward Lelburian Jackson were first discovered in 2022, and an initial autopsy revealed he was killed decades ago

After four years, a piece of the haunting mystery uncovered in the waning waters of drought-stricken Lake Mead has been solved.

Since the remains of an unknown homicide victim were discovered stuffed inside a barrel in 2022, Las Vegas investigators have been searching not for his killer – but for his identity. At a press conference on Thursday, Clark county coroner Melanie Rouse shared his name publicly for the first time: Edward Lelburian Jackson.

The US government could spend hundreds of thousands of dollars on a media campaign in South Africa to figure out why more white Afrikaners are not applying to become refugees to the US, as Donald Trump had hoped.

State department officials, according to an August proposal seen by the Guardian, outlined a roughly $335,000 research and advertising effort after applications to the refugee program “trended lower than expected” since Afrikaners were allowed to apply directly online in November 2025. The document, written by the US mission in South Africa with a department research unit for the embassy in Pretoria, admits officials know little about why.

The strongest El Niño recorded is expected to bring a cascade of hazards to a state still facing wildfire and heat risks, while budget cuts have weakened disaster response agencies

Before this year, the US National Weather Service had never issued a September coastal flood advisory for the San Francisco Bay Area. In the past month, it has had to issue two.

As flood water swallowed intersections and eroded beaches up and down the California coast last week, scientists and emergency managers warned that this is just an early signal of a coming tumultuous winter as an already exceptional El Niño continues to strengthen. It’s been called everything from “super” to “Godzilla”, as forecasters hammer home the message that conditions brewing in the Pacific Ocean could soon climb off the charts, and fuel extreme weather around the world.

A mix of natural disasters could all befall the state at once as it finds itself in the crosshairs of the climate phenomenon

On a cloudless autumn afternoon, sunlight sparkled on the water that had quietly swallowed a busy intersection to the north of San Francisco, as the surrounding rush-hour traffic slowed to a painful crawl.

There were no crashing waves or storm surges to blame for the flood. Marin county was one of many areas up and down the California coast affected by high tides last week, as parts of the Pacific swelled with excess warmth.

Hurricane Nolo is the latest storm to menace the islands as sees warming ocean temperatures fuel more severe weather

With Hurricane Nolo, the islands of Hawaii are grappling with the third major tropical storm in recent months.

Hurricanes Lala in August and Lowell in early September flooded homes and roads, downed trees and toppled electricity lines across the islands. Nolo, which strengthened to a hurricane on Thursday night, is expected to batter the islands with rain and high surf.

Flash flooding in Arizona tourist destination was probably triggered by compounding climate factors, such as drought and warming in Pacific Ocean

• Remote Grand Canyon lodge hit by deadly flash flood boasts fabled history

A deadly flash flood in the Grand Canyon over the weekend was probably driven by a confluence of climate factors, including drought, wildfire scarring and warming temperatures in the Pacific Ocean that can supercharge storms.

At least two people have died, nearly 80 people were rescued and one remained unaccounted for after a surge of water and debris swept through the immensely popular tourist destination on Saturday, fueled by torrents of rain that hit the national park’s Bright Angel Creek area.

A Las Vegas jury has found former South Side Compton Crips gang leader Duane Keith Davis guilty of the murder of Tupac Shakur, bringing the case to a close nearly 30 years after the famous rapper was gunned down.

The jury took about three hours to reach a guilty verdict in a case that relied heavily on multiple confessions from Davis himself, including his description of the killing in the 2019 memoir Compton Street Legend.

National Park Service confirms second death from weekend flash flood as area braces for more storms

A second death was confirmed by National Park Service officials on Monday after a flash flood sent a surge of water and debris through an area of the Grand Canyon over the weekend.

Dozens of visitors had to be evacuated by helicopter during the deluge, which consumed trails and infrastructure. Fifteen people are still missing or unaccounted for, as more heavy rain and thunderstorms in the forecasts threaten additional debris flows, flash floods or rock falls, the NPS said in a statement.

A Las Vegas court is hearing closing arguments in the trial of the South Side Compton Crips gang leader Duane “Keffe D” Davis, who is accused of ordering the murder of hip-hop legend Tupac Shakur.

Davis, 63, is accused of leading a group of men to kill Shakur in retaliation for the beating of his nephew, though not of pulling the trigger himself. Davis has pleaded not guilty.

Move by state department to limit access is part of Trump’s crackdown on both lawful and undocumented immigration

All US immigrant visa applications have been paused by the Trump administration as the state department moves to tighten restrictions and limit access to applicants who they deem could end up relying on US assistance, a state department official confirmed Tuesday.

The agency launched the initiative at all embassies and consulates in early August, according to the official and visa appointments had to be adjusted to accommodate “in-depth training”, according to the official. The state department has been working on updated guidance and training since early this year, “to ensure all consular officers are fully equipped to evaluate every visa applicant comprehensively and consistently”, they added.

One more day of testimony expected as closing arguments set for Thursday and jury likely begins deliberations Friday

Extreme conditions in Washington and Oregon have fueled fast-moving fires, leaving the region draped in toxic plumes – and the danger isn’t over

Piles of twisted metal and ashen debris line the cul-de-sacs where the tranquil suburbs of Spokane, Washington, once stood.

The scale of devastation from a historic fire season of wildfire in the Pacific north-west has come into sharper focus as firefighters wrangle a trio of blazes that consumed at least 846 structures on the eastern side of the state.

As US water wars rage, a tributary of the Colorado River faces unprecedented pressure. Visitors worry how long this aquatic ‘relict’ will last

On an early morning in mid-May, a group of near strangers shoved camping gear and clothes into waterproof bags, slathered on sunscreen, and ambled into the bright-yellow rafts that would carry them down one of the last free-flowing rivers in the American west.

Unhindered by large dams or diversions, the Yampa curves across 250 miles (400km) of alpine tundras, cottonwood forests and ancient red-rock canyons, rising from Colorado’s Rocky mountains to where it joins with the Green River in Utah, much in the way it has for millions of years.

Habitat destruction strongest driver of species loss, with legislation keeping 99% of listed species from going extinct

The Trump administration repealed a crucial part of the Endangered Species Act (ESA) on Friday, finalizing a new rule that will open habitats of imperiled wildlife to development, logging, mining and other uses.

For the last 50 years, the landmark environmental law included a broader understanding of the word “harm”, which ensured that not just the plants and animals themselves were protected but also the places that are critical to their survival. The inclusion of habitat in the “harm” definition was upheld by the supreme court in 1995, which ruled in support of old-growth forest protections relied on by endangered spotted owls.

Models show overwhelming chance that this year’s El Niño to rank among largest going back to 1950

El Niño is strengthening and the risks of a historic event with the power to supercharge extreme weather around the world are rising, according to the latest analysis from the US National Weather Service.

Models show there is now an 81% chance that a very strong El Niño “that would rank among the largest El Niño events in the historical record going back to 1950” will develop before the end of this year, forecasters said in an advisory released on Thursday. There is almost near certainty – a 97% probability – that the conditions will persist through spring 2027.
