Ancient Ecosystem Response To Mass Extinction

Ancient Ecosystem Response To Mass Extinction

As the planet faces the dawn of a sixth mass extinction, scientists are searching for clues about the uncertain road ahead by exploring how an ancient ecosystem collapsed and bounced back from traumatic upheavals. A new study follows the lengthy collapses and revival of South African ecosystems during one of the “big five” mass extinctions, the Permian-Triassic event, revealing unexpected […]

NASA Highlights Drought, Mars, Arctic Warming at Science Conference

Long ago, in the largest canyon system in our solar system, vibrations from “marsquakes” shook soft sediments that had accumulated in Martian lakes. The shaken sediments formed features that now appear as a series of low hills apparent in a geological map based on NASA images. The map was released today by the U.S. Geological Survey (USGS). This map of […]

Antarctica’s Balmy Past

When the atmosphere had much higher levels of carbon dioxide, Antarctica was as warm as California. New research has revealed that 430 million to 50 million years ago, temperatures on the frozen continent averaged 57 degrees Fahrenheit, with part of the surrounding Pacific Ocean reaching up to 72 degrees. In this ancient era, known as the Eocene epoch, carbon dioxide […]

A Changing Jet Stream

Climate Changes

Climate change appears to be affecting the jet stream, altering the weather patterns over the U.S. so that regions can get “stuck” in extreme weather for weeks, a new study has found. The jet stream is the fast-moving, high-altitude air current that shuttles weather from west to east over North America and Europe. But the pronounced warming of the Arctic—where […]
