  • Mussels on Acid
    By studying how mussels adapt to acidic waters near underwater volcanoes, scientists are gaining a better understanding of how climate change could affect the ecology of Earth's oceans. Increasing carbon dioxide in the Earth's atmosphere is leading to acidic water in the oceans, which could

  • Permian Polluters
    At the end of the Permian, about 90 percent of all life on land became extinct. Scientists have now proposed a new theory as to what caused the largest mass extinction known, and it all comes down to gases from giant salt lakes.

  • Big Snake, Warm Climate
    Scientists have found fossil remains of a massive snake that may have measure 13 meters in length. By studying the snake's size, the team is yielding new information about the history of Earth's climate and its connections to the evolution of life.

  • When Diatoms Declined
    Diatoms are an abundant type of plankton in the ocean that play a big role in carbon cycling on Earth. Trends in diatom numbers throughout time can tell scientists a great deal about the climate history of Earth – a history that may need to

  • Dark Moon Cooling
    Scientists may have traced a link between a dark eclipsed moon and cold weather. The key is volcanic eruptions, highlighting the interconnections between the geology, climate and life on Earth.

  • Measuring the Weight of Ancient Air
    In the first study of its kind, researchers will measure the air pressure from nearly three billion years ago by using gas bubbles in lava and tiny craters made by raindrops. The results could indicate what sort of life may have existed on the

  • 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.

  • Signals from an Infant Earth
    Precise dating of zircon crystals suggests that Earth may have been conducive to life even before an epic influx of asteroids pummeled our planet 4 billion years ago.
