"Aboriginal Hotspot: 4000 Stone Artifacts Uncover Ice Age Secrets of Drowned Australian Land"

An analysis of over 4,000 stone artifacts on Barrow Island off northwestern Australia provides insights into Aboriginal life during the last ice age, revealing connections between the island and the mainland. The artifacts, dating back to 29,000-19,000 years ago, suggest a diverse range of tools and materials, indicating trade and exchange between different groups. The study sheds light on the ancient connections and landscape use by Aboriginal peoples during a time period that is virtually unknown elsewhere on the continent.

Ice Age World Map: A Glimpse into the Past.

A map created by cartographer Perrin Remonté shows what the world looked like during the Last Glacial Maximum (LGM), or the last ice age, which occurred roughly 26,000 to 19,000 years ago. During this time, sea levels fell more than 400 feet, exposing large areas of the continental shelf. The climate was cold and dry, with temperatures 6°C lower on average. The polar parts of continents were covered by massive ice sheets, and deserts expanded while rivers disappeared. Several large animals, including the woolly mammoth and saber-toothed tiger, roamed the world in extremely harsh conditions, but are now extinct. The article also discusses the possibility of another ice age and how current industrial activities may delay it.

The Accelerating Retreat of Antarctic Ice Sheets.

A new study has found that parts of the Eurasian ice sheet retreated at a rate of up to 2,000 feet per day at the end of the last ice age, far outpacing the fastest-moving glaciers studied in Antarctica. The finding raises concerns about how quickly ice in Greenland and Antarctica could melt and raise global sea levels in today’s warming world. If air and ocean temperatures around Antarctica were to increase as projected, researchers say ice marching backward hundreds of feet in a day could trigger a collapse of modern-day glaciers sooner than previously thought.
