    The Intersection of Population and Elevation Examined

    This map shows the estimated number of people in 2010 living at different elevation levels across several Southern Asian countries. The database it’s taken from lets users without specialized geospatial training or software compare populations in various environmental contexts in different countries.

    Fresh Evidence of Life on Mars?

    In a landscape shaped by wind and water, is it possible that microbial life was found on Mars in 1976? A new paper indicates life may be present, and a new mission to Mars may confirm the results.

  • New Salt Map of Seas Gives Scientists Taste of Discoveries Ahead

    After less than a month in operation, a new NASA satellite has produced the first map showing how saltiness varies across the surface of the world’s oceans. Salt influences how seawater and heat move around the globe and also tells oceanographers how much rain and evaporation is happening at the surface. Until now, salt measurements…

    The Indiana Jones of Climate Modeling

    By JD Capuano Benjamin Cook is a climate modeler at Lamont-Doherty Earth Observatory, part of the Earth Institute at Columbia University. Cook completed his Ph.D. in environmental science at the University of Virginia in 2007. He was among a select group of scientists awarded a Climate and Global Change Postdoctoral Fellowship by the National Oceanic…

    A new study led by James Hansen of NASA’s Goddard Institute for Space Studies, a part of The Earth Institute, finds that the world’s temperature is reaching a level that has not been seen in thousands of years. The study was published in the September 26, 2006 issue of the Proceedings of the National Academy…
