GIS Makes the Picture Clearer on Climate Change

The Arctic environment is a leading indicator of climate change. The shifts that will eventually affect the entire globe are among the most visible there. A comprehensive understanding of the shifts occurring in this area are crucial now more than ever.

Traditional imagery of the Arctic was collected via aircraft, but is very limited due to the inhospitable and remote nature of the polar region. Now 3-D digital elevation models (DEMs) of the entire Arctic are scheduled for release by 2017. With a resolution of 2 m, these new DEMs are over one hundred times higher resolution than what has previously been available for the entire Arctic. This has been made possible through a unique public private partnership between Esri, the White House and several important partners by way of DigitalGlobe satellite imagery.

Today the first of these rich elevation models covering the State of Alaska is being released. They are the first deliverable of the ArcticDEM project, created after a January 2015 Presidential Executive Order calling for enhanced coordination of national efforts in the Arctic. Climate Change is one of the biggest threats we face, it is being driven by human activity, and it is disrupting Americans’ lives right now. President Barack Obama spoke about the project at an Arctic conference in Kotzebue, Alaska on September 3, 2015 and called for action to reverse the trend of climate change, an exponentially growing problem for the entire planet.
