Democratization of Advanced Computing
• Putting complex models into the hands of researchers and educators who otherwise wouldn’t have advanced capabilities means the tools must be:
– Highly intuitive– Free of jargon, except where its intent is instructive– Usable on existing computing resources– Inexpensive– Responsive support– Applicable to real world problems (as opposed to “toy” problems)– Tied to current events and societal needs
Based on a concept by K. DroegemeierUnidata Summer Workshop 2006Keynote

Why the need for climate modeling in the classroom?
Climate models are the primary research tools used for assessing future climate change.
Public policy decisions rely heavily on climate model simulations.

EdGCM Project Objectives
1) Allow schools to run a global climate model on a desktop computer, encouraging students to participate in the full scientific process including: experiment design, running simulations, analyzing data and reporting on results.

EdGCM Project Objectives
1) Allow schools to run a global climate model on a desktop computer, encouraging students to participate in the full scientific process including: experiment design, running simulations, analyzing data and reporting on results.
2) Facilitate collaborations between the education community and research institutions and among secondary schools and universities. In this way, students will become familiar with the role that teamwork plays in scientific research.

2) Facilitate collaborations between the education community and research institutions and among secondary schools and universities. In this way, students will become familiar with the role that teamwork plays in scientific research.
3) To demystify some of the complexities of how scientists are making forecasts about future climate change.

While I am prepared to accept that there may be global warming, nothing I have seen shows a causal connection. Tim, UK
One of the most persistent arguments made by those who do not believe that climate change is caused by human activity is that there is "no consensus" amongst climatologists about this. Tim Dennell, Sheffield, United Kingdom
Five hundred years ago the scientific consensus was that the world was flat. Thirty years ago, we were about to enter another ice age. Twenty years from now we will all have a good laugh about "global warming". Thumper31
