This is a Iowa State University publication. It uses the IPCC data that dates back to 1994.
The point is there is dearly little anyone in the current administration is going to do or say that will change the minds of most Americans. The data is set, the records incredibly logged into archives and there are states in this United States that have already conquered the knowledge of the climate crisis. This did not happen yesterday. This is an extensively investigated aspect of life on Earth.
Rice cultivation was estimated at 5% of all methane emissions in 1994. I am sure it is more today. In a "Scientific American" article in 2002 it was estimated the percentage was more like 15% and dependent upon the success of the crop. (click here)
Central (click here) to any study of climate change is the development of and participation in an emission inventory process that identifies and quantifies a country's primary sources and sinks of greenhouse gases.(Endnote 1) This process is important because: (1) it provides a basis for the ongoing development of a comprehensive and detailed methodology for estimating sources and sinks of greenhouse gases, and (2) it provides a common and consistent mechanism that enables all signatory countries to the United Nations' Framework Convention on Climate Change (FCCC) to estimate emissions and to compare the relative contribution of different emission sources and greenhouse gases to climate change. Moreover, systematically and consistently estimating emissions at the national and international levels is a prerequisite for evaluating the cost-effectiveness and feasibility of pursuing possible mitigation strategies and adopting emission-reduction technologies.
This document provides information on green house gas sources and sinks, and estimates of emissions and removals for the United States for 1990 1993, as well as the methods used to calculate these estimates, and the uncertainties associated with them. Although estimates are provided for all four years, the 1990 estimates are considered the base year, since under the Framework Convention on Climate Change, countries are to submit inventories of greenhouse gas emissions for the year 1990.
The emission estimates presented here were calculated using the IPCC Draft Guidelines for National Greenhouse Gas Inventories (IPCC/OECD, 1994) to ensure that the emission inventories submitted to the FCCC are consistent and comparable across sectors and between nations. In order to fully comply with the IPCC Draft Guidelines, the United States has provided a copy of the IPCC reporting tables in Annex D of this report. These tables include the data used to calculate emission estimates using the IPCC Draft Guidelines. The United States has followed these guidelines, except where more detailed data or methodologies were available for major U.S. sources of emissions. In such cases, the United States expanded on the IPCC guidelines to provide a more comprehensive and accurate account of U.S. emissions. These instances have been documented, and explanations have been provided for diverging from the IPCC Guidelines (IPCC/OECD, 1994)....
