FY02 and FY03 Climate and Global Change Interagency Inventory.  The Climate and Global Change Interagency Inventory Data Sheet (dtd August 2002)  is a working document that includes information provided by federal agencies regarding their climate and global change research activities.  The data differ in some respects from information reported in the Fiscal Year (FY) 2002 and FY 2003 editions of Our Changing Planet, the annual U.S. Global Change Research Program report to Congress. Some of these discrepancies are the result of differences between requested and enacted levels of funding. In addition, some programs in the President's FY03 request as part of CCRI were not labeled as CCRI programs in the inventory.
