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.
Special keynote address, discussion panel, and reception to engage and enlighten scientists
- A keynote address by Margaret Leinen, Director of the Scripps Institution of Oceanography, current president of the American Geophysical Union, and a US State Department Science Envoy.
- A conversational reaction panel of GIScientists moderated by Mike Goodchild (UCSB Geography emeritus) with John Wilson (USC Spatial Sciences Institute), Marco Painho (U. Nova de Lisboa Geography), Ming Tsou (San Diego State Geography), and Cyrus Shahabi (USC Computer Science).
- Audience Q/A and discussion.

Recent innovations in information, analyses, and science-policy linkages can help guide the planet towards a more resilient future.
For many of us when we think about the ocean, it’s a situation of “out of sight, out of mind.” In our limited awareness of the ocean, we see only the surface and think only of vast expanses of lifeless water, not realizing all of the complexities at play.
In fact, the ocean provides over HALF of the oxygen that we breathe. It regulates ALL of our weather patterns, it feeds us, and it provides for our energy and economy.
The ocean is a champion at absorbing human-derived (anthropogenic) CO2. Around half of all carbon dioxide produced by humans since the industrial revolution has dissolved into the world’s oceans. Coastal habitats store five times more carbon than do inland tropical forests. This has all helped to slow global warming.
So in reality, the ocean is vital to all of us, no matter WHERE we live. Continue reading
“We, the people, still believe that our obligations as Americans are not just to ourselves, but to all posterity. We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations. Some may still deny the overwhelming judgment of science, but none can avoid the devastating impact of raging fires, and crippling drought, and more powerful storms.”
Thus spoke President Barack Obama in his 2nd inaugural address, to the delight of many, if not most in the scientific community. Indeed, there are many societal problems across the world that increasingly revolve around science. These include pollution and waste management, pandemics and biosecurity, access to clean air and clean drinking water, response to and recovery from natural disasters, choices among energy resources (oil and gas versus nuclear versus “alternative”), and the loss of open space in urban areas, as well as biodiversity in rural areas. And yet, there is a tension between the world of science, which is focused on discovery, and the world of policy making, which is focused on decisions.
Climate Change Is a Geographic Problem
Reducing the risks caused by climate change is an immense challenge. Scientists, policy makers, developers, engineers, and many others have used GIS to better understand a complex situation and offer some tangible solutions. Technology offers a means to assess, plan, and implement sustainable programs that can affect us 10, 20, and 100 years into the future. Continue reading
