  • The Case of the Missing Ice
    By modeling ice sheets in Antarctica, scientists have changed the way we think about Earth's transition 34 million years ago from warm 'greenhouse' to the current, cool 'icehouse'. The new study has important implications for how we understand climate change and its affects on the

    Scientists have shed new light on the processes behind the Ice Ages experienced by Earth over the past 2.5 million years. Research indicates that they are ultimately linked to shifts in solar radiation caused by changes in the Earth's rotation and axis.

  • Ancient Booms and Busts
    Research suggests that a period of global warming strongly influenced plants and animals some 53 million to 47 million years ago during the Eocene epoch. The study could help scientists understand the effects that climate change will have in Earth's future.

    'Geoengineering' refers to human-made changes to the Earth's land, seas or atmosphere that are intended to help slow climate change. However, some scientists are worried that geoengineering techniques may cause more harm than good.

    During the last ice age, glaciers advanced over much of the Earth's surface. Scientists have long wondered why the planet didn't freeze over entirely. New research shows that Earth may have been saved from a runaway 'icehouse' by plants.

    New research shows that a 'brief' ice age in Earth's past actually lasted for 30 million years. During the ice age, global warming was curbed by the natural burial of organic carbon underground. The study is helping scientists understand the historical connections between the biosphere

    Scientists have determined that the rise of oxygen on Earth may have caused the planet's first ice age. The research team believes that rising oxygen levels could have consumed atmospheric greenhouse gases, ultimately cooling the entire planet and profoundly influencing the evolution of life.

  • 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?
