Chicxulub Asteroid Dust Cloud Trapped Heat to Devastate Earth
New research shows the Chicxulub asteroid impact 66 million years ago generated an impermeable fine-dust cloud that trapped thermal radiation near Earth’s surface, creating extreme heat conditions and global wildfires that far exceeded earlier temperature models and devastated terrestrial life. When the roughly six-mile-wide asteroid struck Mexico’s Yucatán Peninsula 66 million years ago, it did … Read more
