• Changing climate: How dust changed the face of the Earth

    In spring 2010, the research icebreaker Polarstern returned from the South Pacific with a scientific treasure – ocean sediments from a previously almost unexplored part of the South Polar Sea. What looks like an inconspicuous sample of mud to a layman is, to geological

  • Ancient forests stabilised Earth’s CO2 and climate

    UK researchers have identified a biological mechanism that could explain how the Earth’s atmospheric carbon dioxide and climate were stabilised over the past 24 million years. When CO2 levels became too low for plants to grow properly, forests appear to have

  • Key species of algae shows effects of climate change over time

    Historical comparison of competition among algae in waters around the Pacific Northwest provides more evidence for increased ocean acidification.

    A study of marine life in the temperate coastal waters of the northeast Pacific Ocean shows a reversal of competitive

  • Meteorite minerals hint at Earth extinctions, climate change

    A huge asteroid that wiped out the dinosaurs may not have been the only cosmic event to cause mass extinctions or change Earth’s climate. Tiny minerals leftover from many smaller meteorites could provide the geological evidence needed to show how rocks falling
