Glaciers are one of the main driving forces affecting Earth's climate and landscape. From Alpine, or Mountain, glaciers, to Tidewater glaciers and icebergs, these massive sheets of ice are constantly moving and changing, almost like a living being. Warming temperatures are causing most glaciers to recede, leaving a changed landscape in their wake. Located in some of the most inhospitable areas of the planet, scientists are venturing to glaciers to study them, looking for clues to climate changes from the past and in the present.
