    Why are Past Surface Temperatures and CO2 Concentrations Important?

    By burning fossil fuels for heating, electricity, transportation and other purposes, humans add CO2 to the atmosphere. Yet, by comparing ways in which the Earth’s temperature, CO2 concentration, sea level and ice sheets have changed in the past, we are able to learn valuable lessons about the climate system of today and tomorrow.

    This Bird Flies South for the Winter

    Migrating south in the winter is a behavior that Antarctic scientists share with many species of birds, although the scientists fly just a bit further south. For the IcePod team it was time to join the migration so they could test their equipment in the most challenging environment the Earth has to offer.
