Climate

  • A Warm Breath of Carbon Dioxide
    When the sun was young, it didn't produce enough heat to unfreeze ice on our planet. So why was the early Earth covered in liquid water and not ice?

  • The Rise of Slime
    Human activities are having disastrous effects on the health of the world's oceans according to a new prognosis. Factors such as overfishing and climate change must be addressed in order to ensure the future health of one of our planet's most important biological resources.

  • A Swift Drop into Deep Freeze
    Scientists have discovered traces of fossilized plants and insects in an ice-free region of Antarctica. The finding is evidence of what Antarctica was like before an abrupt cooling of the Earth roughly 13.9 million years ago.

  • Greenhouse Earth
    New research shows that 40 million years ago the Earth was experiencing warmer seas with little or no ice on the planet. The finding could help scientists understand the effects of climate change on Earth today.

  • Extinction Followed Eruption
    A new study indicates that undersea volcanic activity may have triggered an extinction event in the Earth's oceans. The extinction occurred 93 million years ago and is responsible for creating some of today's major oil reserves.

  • 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.

  • Viruses Keep Us Breathing
    New research shows that viruses infecting microorganisms in Earth's oceans might ultimately be responsible for much of the oxygen produced on our planet. The study highlights important links between life and the global climate of Earth.

  • 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.
