  • Turning Earth Into Venus
    A new study finds that prolonged heating of a planet's atmosphere can shut down plate tectonics. The study could have important implications for our understanding of climates on terrestrial planets like Earth and Venus.

  • Oceans Gasping for Breath
    During the Jurassic, global warming and severe environmental change led to the extinction of many species. One of the most intriguing effects was that the oceans became starved of oxygen.

  • A Question of Climate
    At its birth, our young planet was a ball of molten hot rock. How long did it take to cool down? The answer could indicate the conditions necessary for life to arise, and provide insight into the evolutionary history of life on Earth.

  • Snowball Melted
    New evidence shows that periods of warmth may have occurred during a time in Earth's history when scientists had thought the entire globe was frozen over. The new findings have implications in our understanding of how life interacted with the changing planetary environment of Earth.

  • Earth, She’s Hot and Cold
    New research concerning the transition of the Earth's climate 300 million years ago from an ice age to an ice-free planet has yielded new insights into the processes of climate change. The new findings will also tell us about how Earth's changing climate throughout history

  • Cyanobacteria Catch 22
    Two and a half billion years ago, photosynthetic organisms started releasing oxygen into the atmosphere, changing the balance of gases on Earth. But researchers have long been puzzled as to how the organisms could make that oxygen without poisoning themselves. Now, two groups of

  • Sick Earth?
    What caused the Permian-Triassic extinction, the largest mass extinction in Earth's history? The most likely explanation for the disappearance of up to 90 percent of species 250 million years ago, said David Bottjer of the University of Southern California, is that "the earth got

  • Earth’s Crazy Climate
    Ancient rocks from the bottom of the Pacific Ocean suggest dramatic climate changes during the dinosaur-dominated Mesozoic Era, a time once thought to have been monotonously hot and humid.
