Global Sea Ice Reaches Record Low; Researcher Explores Lake Tahoe's Depths

Global sea ice extent hit a record low in early February, falling below the previous February 2023 record, according to the EU's Copernicus Climate Change Service. Arctic sea ice reached its lowest February extent, 8% below average. Antarctic sea ice was 26% below average, the fourth lowest on record. Meanwhile, in Lake Tahoe, an independent researcher is using a custom-built rover to explore the lake's depths. Chase Petley aims to uncover mysteries at the bottom of the lake, including a massive crevasse suggesting greater depth and a 400-foot-high rock formation. His discoveries, documented on the Instagram page Mysteries of the Deep, include unexpected aquatic life.
