Broken Links on – Global Climate Change Models

Here are some notes on broken links and bad practices.  I put notes on my search for climate models.  I do these rough searches to get started on a complete review of a topic group on the Internet.  Picking a hard enough problem at global scale is the only way to stay organized and keep all the issues and alternatives in mind.
At is says, “Please report any missing content”. and the “Report Issue” goes to which is not user friendly.  Just put a form.  From the sparce content at, it does not look used. Generally Github is NOT reliable issue handling system, too diffuse and too many single points of failure.
Your “About” pulldown has Overview, Staff, Location.  There should be a consistent “contact us” on every one of your pages.  I can suggest efficient ways to do that. shows 2,660 entry points on Google just now.
EVERY page should have a full title, not” but “Lawrence Livermore National Laboratory, Program for Climate Model Diagnosis and Intercomparison (LLNL PCMDI)”
I am looking for the source code of the models.  I know your group is only looking at a piece of the whole, but every node in the “global climate” modeling network should have complete context information to never leave anyone without a map to know where they are in the global model space.
As it is now, every page that mentions “global climate change” or “climate models” is designed, maintained and managed independently.  No uniform practices, much much duplication.  No two pages using similar styles, navigation, components, much duplication.  Every person trying to work on this topic, and every new person (there are about 2 Billion first time learners in the world now) has to sort through this mess on the Internet.  Adding new pages that no one can find is not the answer.
