Study Warns California Continues to Face Threat of Megadrought [Video]

Study Warns California Continues to Face Threat of Megadrought

Study Warns California , Continues to Face , Threat of Megadrought. 'Newsweek' reports that California may not have cured the state's water woes, despite several years of snow-heavy winters. . According to NASA satellite data, recent snowfall has been insufficient to offset the impact of an ongoing megadrought across the western states. . A new paper published in the journal, 'Geophysical Research Letters', details how groundwater supplies remain concerning for both domestic and agricultural use. Gravity Recovery and Climate Experiment (GRACE) satellites revealed that the entire Great Basin groundwater supply has dropped by 16.5 cubic miles in the last 20 years. The data highlights that while snowmelt does help resupply groundwater levels, it is not enough to replenish the current diminished levels. In years like the 2022-23 winter, I expected that the record amount of snowfall would really help to replenish the groundwater supply. But overall, the decline continued, Dorothy Hall, Study co-author and University of Maryland earth scientist, via NASA statement. 'Newsweek' reports that the U.S. southwest has been facing a megadrought since the beginning of the millennium. . A megadrought is a drought that lasts two or more decades. , Jonathan Overpeck, Dean of environmental studies at the University of Michigan, via 'Newsweek'. The current southwest megadrought started in 1999 and has become the longest drought in U.S. history, and also the most severe in at least 1,200 years, Jonathan Overpeck, Dean of environmental studies at the University of Michigan, via 'Newsweek'. With the ongoing threat of drought, farmers downstream often can't get enough water. The ultimate solution will have to include wiser water management, Dorothy Hall, Study co-author and University of Maryland earth scientist, via NASA statement

NASA Discovers Mysterious Martian 'Hole' That Could Shelter Future Astronauts [Video]

NASA Discovers Mysterious Martian 'Hole' That Could Shelter Future Astronauts

NASA Discovers Mysterious , Martian 'Hole' That Could , Shelter Future Astronauts. 'LiveScience' reports that scientists have discovered a mysterious pit on the side of an ancient volcano on Mars. The discovery has generated excitement due to what it may reveal beneath the Red Planet's surface. Images of the pit were first captured by NASA's Mars Reconnaissance Orbiter. . The hole's origins and depth remain unknown. This pit, found on an extinct lava flow of Arsia Mons, appears to be a vertical shaft that scientists believe could lead to a much larger cavern. . The pit could also be a deep lava tube formed at a time when Arsia Mons was still active. Due to the thin atmosphere and lack of a magnetic field, scientists have looked to pits and caves to potentially shelter astronauts in the future. . 'LiveScience' reports that if Mars ever hosted life, those organisms may have sheltered in pits like this one, which could offer protection and even allow life to flourish. . If future missions reveal that the pit leads to a large open cave, it could provide the perfect landing site for crewed missions to Mars in the future.
