Hiker accidentally stumbles upon 280-million-year-old discovery in Italian Alps: 'Very important'

A hiker in the northern Italian Alps came across an unexpected discovery pointing to some of the most mysterious aspects of nature — past and future. As explained by the Guardian, scientists said they believe Claudia Steffensen and her husband uncovered the first trace of an entire prehistoric ecosystem dating back 280 million years to the Permian period, which immediately preceded dinosaurs.  The discovery happened in Lombardy's Valtellina Orob…

Ancient Fossils Reveal Survival Secrets of Earth’s Worst Mass Extinction

Can plants uncover the survival secrets of Earth’s darkest days? A research team from University College Cork (UCC), the University of Connecticut, and the Natural History Museum of Vienna has uncovered how plants responded to catastrophic climate change 250 million years ago. Their study, published in GSA Bulletin, details the prolonged recovery of ecosystems following [...]

Plants that survived the worst ever mass extinction tell story of rapid global warming

Modelling of changes in vegetation during Earth’s most severe mass extinction event at the end of the Permian period could help explain how our planet’s biomes will change under conditions of another mass extinction amid current global warming. Known as the “Great Dying”, the end-Permian mass extinction saw the disappearance of about 90% of marine species and 70% of land-based vertebrates. Overall, 57% of all biological families and 80–95% of sp…

Permian mass extinction linked to 10°C global temperature rise that reshaped Earth's ecosystems

The mass extinction that ended the Permian geological epoch, 252 million years ago, wiped out most animals living on Earth. Huge volcanoes erupted, releasing 100,000 billion metric tons of carbon dioxide into the atmosphere. This destabilized the climate and the carbon cycle, leading to dramatic global warming, deoxygenated oceans, and mass extinction.

If you find 1.5 degrees of warming shocking, then be glad you didn't live at the end of the Permian. About 252 million years ago, a huge mass extinction occurred, which was accompanied by a temperature increase of no less than 10 degrees. During that period, there were large volcanic eruptions that released 100,000 billion tons of CO2 […] More science? Read the latest articles on Scientias.nl .
