Global Change Consulting Consortium, Inc.

Global change encompasses hundreds of issues, the number depending upon how fine a focus one brings to bear.  Here we present a selection of issues, as summaries of the body of knowledge to date, and for a number of topics we identify work that we see as of high value, often novel, and within our expertise in the consortium.  We present the issues in varying degrees of detail:

Three presentations are of significant length, combining detail and breadth:

            Forest issues

            Water issues

            Challenges for a renewable / low-C energy economy


These are not position statements of the GCCC on actions that are needed; rather, they present the known factual background and some of the positions that have been taken by various parties.  With these pages, we aim to demonstrate our grasp of the issues.  We also develop some novel viewpoints.  Within the page on forest issues, there is also a link to a list of projects that we foresee that clients may request the GCCC to do.  We are actively engaged on water issues on a current contract.


The two issues pages draw on our backgrounds and years of work in universities, national laboratories in 3 countries, and scientific agencies, plus our contacts with researchers, agency personnel, and private enterprises across the US and a number of other nations.  The pages contain links to many other Web pages, media pages, journal articles, and books for further exploration of the issues.

For a yet larger number of issues, we provide identifiers or simple outlines.   We will develop these into longer presentations, as time permits.  Our priority is to do the 'hands-on' work on issues for which clients engage us; the list here serves to demonstrate our awareness and our considerable interest in a wide variety of issues.
