Democratization of Advanced Computing

• Putting complex models into the hands of
  researchers and educators who otherwise wouldnt
  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. Droegemeier Unidata
Summer Workshop 2006 Keynote

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

• 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.

• 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.

Addressing Public Skepticism By Reducing the
Mystery of the Techniques
BBC website blog - a typical day in July (2006)
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".

Computer simulations of the Earth based
on fundamental physics and empirical
parameterizations
