Scientists make stunning discovery while studying the deepest lake in North America — here's what they found
The deepest lake in North America is recovering its water level after it reached a record low in 2024.
In February, Great Slave Lake in Canada's Northwest Territories was 20 centimeters (7.9 inches) higher than it was a year prior, as Cabin Radio reported. As of March 7, it had picked up another 5 cm to reach 9.8 inches.
The province's Department of Environment and Climate Change said Great Slave Lake's water level has been "slowly rising since mid-December," per the outlet, though the spring melt will determine where it goes from here.
The lake is named after a group of the Indigenous Dene people. The Dene also call themselves the Slavey when speaking English, per The Canadian Encyclopedia. It's the second-largest lake in the country, fifth-largest on the continent, and 10th-largest in the world.
Humans have lived around the lake, which reaches a maximum depth of 614 meters, for 7,000 years. It has a significant impact on the Mackenzie River and forms the basis of traditional livelihoods and economies, according to the Northwest Territories government.
In 2020, the lake reached its highest level since 1930. But it had been "extremely low" the year before, Cabin Radio reported. Since 2022, the area has been in a drought.
Both the water level fluctuations and dry conditions are common symptoms of the warming planet. The burning of dirty energy sources emits heat-trapping gases into the atmosphere, which envelop Earth like a blanket and contribute to more frequent and severe extreme weather as well as rising global temperatures that disrupt the water cycle.
In the Great Slave Lake basin, water levels are bouncing back but still low. That could again disrupt the barge resupply on the Mackenzie like last year, and higher-than-usual temperatures in January were cause for concern. Winter precipitation was average, and that was expected to continue for a few months for most of the NWT, Cabin Radio reported.
To help stabilize the lake and other climate conditions, we can turn to clean energy sources that don't pollute the environment or lead to planetary warming. Use or install electric lawn equipment and energy-efficient appliances, which can also save you money. Even small steps such as eating plant-based meals, using less plastic, and taking alternatives to personal vehicles can make a big difference.

The Fascinating Way Hurricanes Will Get Their Names in 2025
As hurricane season ramps up, we are always wondering how the names for hurricanes and tropical storms are picked. In the U.S., the Atlantic hurricane season is typically June through November. The National Oceanic and Atmospheric Administration is predicting an "above-normal" tropical storm season for 2025, with an estimated 13 to 19 storms that will reach winds high enough to be named. That means we'll be hearing these names on news reports in the coming months. A storm gets a name once it reaches tropical storm status (that is, it has a rotating circulation pattern and sustained winds of 39 miles per hour). The list is compiled by the United Nations' World Meteorological Organization. The list of 21 Atlantic hurricane names is alphabetical, and letters Q, U, X, Y, and Z are never used. Before 1978, names were exclusively female, but they have since alternated between male and female names. The WMO chooses names that are short and distinctive to help convey information with clarity, and they select a mix of English, French, and Spanish names. The names are planned out through 2028, but the lists actually repeat every six years. The names of the 2025 storms will be used once again in 2031. The only time the rotating lists of names changes is if a name is retired. Andrea Barry Chantal Dexter Erin Fernand Gabrielle Humberto Imelda Jerry Karen Lorenzo Melissa Nestor Olga Pablo Rebekah Sabastien Tanya Van Wendy Yes, according to the NOAA, a hurricane name will be retired if a storm is "so deadly or costly that the future use of its name for a different storm would be inappropriate for reasons of sensitivity." If that happens, the WMO will choose another name to take its place. Since 1954, a total of 99 hurricane names have been retired and replaced, including Andrew, Katrina, Sandy, Irma, Ivan, and Hugo. Prior to 2021, if the list of 21 named storms was exhausted in a given year, the remaining storms would be named according to the Greek alphabet (Alpha, Beta, Gamma, Delta, etc.). The WMO changed that procedure after the active 2020 season, when all 22 names and the first 9 letters of the Greek alphabet were used. The committee made the change "because it creates a distraction from the communication of hazard and storm warnings and is potentially confusing." Instead, a list of alternative names was compiled, and the WMO will choose names from that list if the need arises.

At the US-Mexico border, volunteers conduct a grim search Once a month, retiree Abbey Carpenter leads volunteers through a field of dunes near the border, searching for the remains of migrants. She has located 27 sites in southern New Mexico in under two years, artifacts of a wave of migration that has ebbed to a trickle. But the bones – femur, rib, jaw – take her breath away each time. In them, Carpenter, who taught English as a Second Language, sees the journeys made by her former students ‒ migrants who live and work in the United States and learned English in her classroom. Men in construction. Women in service industries. Another volunteer told USA TODAY: "Emotionally, it was more than I expected." Tourists run for their lives from erupting Mt. Etna Videos circulating online show people running as smoke from the side of Mount Etna, an active stratovolcano in Sicily, filled the air Monday. Europe's largest and most active volcano, Mount Etna, is located on the eastern coast of Sicily, Italy, in the province of Catania, according to the U.S. Geological Survey (USGS). The active stratovolcano is known for its frequent and persistent eruptions, and volcanic activity in the region can range from explosive eruptions to lava flows and ash emissions, USGS says.

Today's talkers Bill Clinton reveals key White House details in murderous new political thriller "We had this just gut-wrenching conversation because in the beginning, we were excited – what would it be like to write a book that was from the point of view of the first gentleman, the first woman president's husband? It had all kinds of fascinating ramifications. But then something happened while we were doing it, and I realized we hadn't created anybody you could like." ~ Former President Bill Clinton to USA TODAY about his partnership with bestselling author James Patterson. USA TODAY books reporter Clare Mulroy met the pair to discuss their third novel, "The First Gentleman." Photo of the day: Dread in the dugout History was made in the NCAA baseball tournament. After losing to Louisville on Saturday and Wright State on Sunday, the Vanderbilt Commodores became the first No. 1 overall seed to be eliminated in the NCAA baseball regionals altogether since UCLA in 2015 and the first No. 1 seed under the current format to fail to at least reach its regional final. The weekend's upsets serve as a black eye for the SEC.

Suddenly a hole appears: international finds himself stuck on the pitch
This article was translated into English by Artificial Intelligence. You can read the original version in 🇩🇪 here. It was supposed to be a magnificent football evening: floodlights, fans, flags, and a home game against Denmark. But instead, on June 6, 2022, the Austrian national team experienced a real drama in several acts. Advertisement Even before the kickoff, there was the first bizarre incident: before the ball could even roll, the power went out. It was as if the Ernst Happel Stadium had personally decided to indulge in romantic candlelight rather than provide a stage for Nations League football. A silent protest against the controversial UEFA format, so to speak. In any case, the match between Austria and Denmark was only kicked off after a 90-minute delay. The interim would have been enough for at least part of "Sissi"! Final whistle overshadowed by "hole incident" But anyone who thought it would finally be all about football was sorely mistaken. The 1-2 defeat of the Austrian team was quickly forgotten after the final whistle! Advertisement As soon as the game was over, Danish striker Andreas Skov Olsen couldn't believe his football boots: right in the center circle—where the game usually begins—a hole appeared out of nowhere. Not a harmless molehill, but a knee-deep crater, more commonly seen in the Salzburg region or Tyrol. Skov's half lower leg disappeared into it! Luckily, only the foot got stuck and not the entire team. TV cameras captured the spectacle and filmed some Danes descending into the newly formed abyss of the Ernst Happel Stadium. Meanwhile, other players stood around the hole like archaeologists at an excavation. The rain was to blame! The later explanation? Rain! Lots of rain. So much that the pitch apparently decided to slowly sink into the earth's core. Perhaps it had seen enough—and just wanted to hide in light of the weak performance of "red-white-red". Advertisement However, the Austrian Football Association reassured the public: The problem would be resolved, and specialized technicians would examine the pitch, according to the association. And indeed: a few days later, the second home game against France could take place as planned. The mysterious hole had disappeared just as quickly as it had appeared. 📸 Christian Hofer - 2022 Getty Images
