Global sea ice reaches new record low
Global sea ice reached a new record low in February, according to the European Union's Copernicus Climate Change Service. This data, which combines the extent of sea ice from the Arctic and Antarctic, has records that date back to the late 1970s.
Previously, 2023 held the record low for global ice following decades of decline. Scientists blame an Arctic heat wave for the new record, which prevented the normal growth of ice in February.
Arctic sea ice reached its lowest monthly extent for February, at 8% below the historical average, Copernicus said. The Arctic had previously set a record low for minimum (summer) ice just last year in September.
According to NOAA, sea ice helps prevent further warming of the globe, and the loss of ice impacts natural ecosystems on land and below sea-level.

Colossal eruption carves 250,000-mile-long 'canyon of fire' into the sun (video)
When you buy through links on our articles, Future and its syndication partners may earn a commission. On July 15, a colossal filament erupted from the sun's northeastern limb, dramatically reshaping part of our star's surface, albeit briefly, and unleashing a coronal mass ejection (CME) into space. The outburst was so powerful that it carved a glowing trench of hot plasma more than 250,000 miles (about 400,000 kilometers) long, roughly the distance from Earth to the moon. The explosive event was captured in stunning detail by NASA's Solar Dynamics Observatory (SDO), showing the filament unraveling as solar material arcs and cascades through the sun's atmosphere. As the filament collapsed, it left behind what some call a "canyon of fire," with towering walls estimated to rise at least 12,400 miles (20,000 km) high, according to These glowing rifts form when the sun's magnetic field lines violently snap and realign after an eruption, leaving behind a searing hot trench of plasma that traces the reshaping magnetic field, according to NASA. This fiery chasm isn't just a visual spectacle. Filaments are cooler, dense ribbons of solar plasma that can hang suspended above the sun's surface by magnetic fields, according to NOAA. When these become unstable, they can erupt dramatically, sometimes launching coronal mass ejections (CMEs) into space — powerful blasts of solar plasma and magnetic fields that can trigger geomagnetic storms here on Earth. Coronagraph imagery from the Solar and Heliospheric Observatory (SOHO) and GOES-19 satellite suggests that while the filament eruption did release a CME, there is no Earth-directed component. "The CME is heading away from Earth," aurora chaser Vincent Ledvina wrote in a post on X. "Here is the CME in LASCO C2 (left) and CCOR-1 (right) which has a later frame of the CME further spread out. The front is traveling pretty slowly and away from Earth." You can keep up to date with the latest northern lights forecasts, alerts and geomagnetic storm warnings with our aurora forecast live blog.

Without weather forecasters, our canaries in the storm, expect disaster
Before modern forecasting, hurricanes were mass casualty events. The 1900 Galveston Hurricane killed over 8,000 people, wiping out an entire city with a 15-foot storm surge. Less than a century ago, Hurricane Okeechobee killed over 2,500 Floridians in a tragedy that today would be largely preventable. We've come a long way since the days when hurricanes struck without warning. I know, because I helped develop the systems that save countless lives and give communities time to prepare. That was my job until February, when I was terminated by President Trump and Elon Musk's Department of Government Efficiency alongside hundreds of other scientists at the National Oceanic and Atmospheric Administration. Since then, I have continued my work in hurricane forecasting through Cooperative Institute research; however, the cuts left deep holes across NOAA's forecasting teams that've not been filled. This purge isn't 'cutting waste' — it is dismantling America's hurricane monitoring systems. At the National Oceanic and Atmospheric Administration, I worked on the next-generation Hurricane Analysis and Forecast System. This system enabled emergency managers to issue timely evacuation orders during life-threatening hurricanes like Helene and Milton, helping prevent thousands of potential fatalities. Yet even with cutting-edge forecasting, Helene revealed new, urgent challenges. In the last decade, freshwater flooding surpassed storm surge as the leading cause of hurricane-related deaths. Helene's victims were coastal residents and mountain communities, caught unprepared by catastrophic inland flooding. Dozens more died — victims of power outages, delayed medical care and collapsed infrastructure in the days after the storm passed. If our warning systems don't evolve to keep pace with rapidly changing storms, Helene's damage may seem merciful compared to future disasters. Precisely when adaptation is most urgent, political decisions have systematically dismantled our protective infrastructure. Key vacancies remain across NOAA's local forecast offices, satellite operations and modeling teams — many of which are already stretched thin this hurricane season. Without continuous investment in modeling and surveillance, hurricane season, which officially began June 1, will become even deadlier and harder to predict. DOGE's decimation of the forecasting workforce unravels a century of progress in hurricane survival rates. While the full impact of these cuts won't be seen overnight, the damage will compound the longer these positions go unfilled. The National Oceanic and Atmospheric Administration isn't just a research agency; it's America's first line of defense against natural disasters. Forecasting is the foundation of all response efforts. While scientists aren't knocking doors with evacuation orders ourselves, we're the ones telling first responders when, if, and whose doors they should knock on. When NOAA functions at full capacity, emergency managers have the tools they need to prepare their communities. NOAA's remaining scientists and National Weather Service forecasters will give their all this hurricane season to deliver the most accurate forecasts possible, but dedication can't make up for a system that's been hollowed out, and grit can only hold together this critical system for so long. Privatizing these forecasting services creates a dangerous 'pay-to-play' model for life-saving information. This approach wouldn't just create barriers for low-income families; it would hamstring small municipalities and volunteer emergency services trying to protect their communities. The private sector cannot fill this void. The National Weather Service processes over 6 billion observations daily and issues approximately 1.5 million forecasts and 50,000 warnings annually. No private entity possesses infrastructure that can match this scale and reliability. There is a better path forward. By recommitting to public science and restoring forecasters' positions, we can build systems that adapt to changing storms, accurately track flood zones and storm paths, and provide both inland and coastal communities with the advanced warning they need to stay safe. We owe this to every family who will face the next Helene or Milton. Congress must act urgently to restore NOAA's full operational capacity and reject all efforts to privatize these essential services. The FY26 federal budget proposes a $1.3 billion cut to NOAA's core operations, such as satellite programs essential to forecasting, programs supporting climate modeling and even public education. NOAA can't issue life-saving warnings if its data stream has gone dark. And the research that drives improvements in modeling and forecasting is threatened if some of the budget proposals come to fruition. There have been some positive developments from Congress. The House Republicans' fiscal 2026 Commerce-Justice-Science spending bill, announced on Monday, proposes a much-smaller cut of $387 million, bringing the NOAA budget to $5.8 billion. While it's a modest improvement, it still does not fully cover the financial needs of an agency tasked with protecting hundreds of millions of Americans. Hurricane forecasting shouldn't be treated like a luxury or a political football. It's public infrastructure that's as essential as our power grids or water systems. Storm surges don't check voter registrations before flooding homes, and hurricanes won't stop based on who occupies the White House. Without urgent action in this year's budget, we risk turning the worst-case scenario into reality. The question isn't whether the storms are coming. It's whether we'll be ready when they do.

Underwater expedition unveils new imagery of sunken World War II destroyer
HONIARA, Solomon Islands - Maritime experts on an expedition around the Solomon Islands in the South Pacific recently explored the wreckage of the USS Laffey, a destroyer sunk during a pivotal series of battles in World War II. According to the USS Laffey Association, the ship went down on Nov. 13, 1942, during the Naval Battle of Guadalcanal and currently rests upright about half a mile beneath the surface in a region known as the Iron Bottom Sound — a graveyard for dozens of ships and hundreds of planes lost during the six-year-long global conflict. The latest mission, expedition NA173, was conducted by the nonprofit Ocean Exploration Trust and supported by NOAA. Over a stretch of 21 days, researchers used a remotely operated vehicle and sophisticated imaging technology to survey the wreckage and other historic sites. War Trophy From George Washington's Army Discovered Amid British Shipwreck Photos released by the team show the Laffey still sitting upright on the seafloor with much of her bow and midsection intact despite more than 80 years underwater. Among the discoveries was a plaque that is still legible, showing the ship's name and builder information despite decades of exposure on the bottom of the Pacific. The ship's wreckage was originally discovered in 1992 during a National Geographic Society expedition led by renowned oceanographer Dr. Robert Ballard, who is most famous for locating the Titanic in 1985. Since that initial discovery, the Laffey has been explored less than a handful of times, making this latest adventure a unique opportunity to document the wreckage's condition. According to the USS Laffey Association, a torpedo led to the ship's demise after sailors engaged several Japanese battleships in a ferocious battle. Historical records indicate that 59 sailors were killed or lost during the attack on the ship, with more than 100 wounded. Noaa Mission Finds Unexpected Discovery At Site Of Sunken Uss Yorktown Historians say during the broader conflict, located more than 1,000 miles northeast of Australia, some 20,000 lives were claimed from both the Axis and Allied powers. Researchers believe at least 111 ships and 1,450 planes were lost in the region during the war, but only a small fraction of these wrecks have been thoroughly explored or documented. During the three-week-long exploratory mission, experts also investigated the wrecks of Australia's HMAS Canberra - the largest warship ever lost in battle by the Royal Australian Navy - and several other sites belonging to the U.S. and article source: Underwater expedition unveils new imagery of sunken World War II destroyer
