When countries began going into lockdown last winter and spring, clearer skies from reduced traffic and industry were hailed as a rare bright spot during a difficult time. But a study published in Geophysical Research Letters in December 2020 shows that those blue skies had an unexpected side effect: They made the Earth slightly warmer. […]
By Jeremy Deaton Shreya Ramachandran, 17, remembers witnessing California’s water crisis firsthand on a visit to Tulare County in 2014, when she was still a preteen. Tulare spans a large swath of farmland in California’s Central Valley, and at that time, locals were facing dire water shortages amid an ongoing drought made worse by climate […]
By Katherine Kornei Clear-cutting a forest is relatively easy—just pick a tree and start chopping. But there are benefits to more sophisticated forest management. One technique—which involves repeatedly harvesting smaller trees every 30 or so years but leaving an upper story of larger trees for longer periods (60, 90, or 120 years)—ensures a steady supply […]

The rate of worldwide ice loss has increased by more than 60 percent in the past three decades, a study published in The Cryosphere on Monday found. “The ice […]
By Aaron W Hunter A chance discovery of a beautifully preserved fossil in the desert landscape of Morocco has solved one of the great mysteries of biology and paleontology: how starfish evolved their arms. Starfish are one of the most recognizable animals on our planet. Most people probably associate them with trips to the beach, […]
New fossils uncovered in Argentina may belong to one of the largest animals to have walked on Earth. Scientists attribute the fossils, which so far consist of 24 tail vertebrae and parts of the pelvic and pectoral girdle, to a titanosaur, CNN reported. Titanosaurs are a kind of sauropod dinosaur that stood on four legs, […]
