With growing concern about climatic changes that could result from increased atmospheric carbon dioxide, it is appropriate to use the improved statistics on the production and use of fossil fuels which are now available and to review the CO 2 dischar

Energy consumption models are useful in the analysis of many energy and resource problems. Fossil fuel consumption models are especially useful in forecasting future atmospheric CO 2 levels. Simple models are frequently used to develop scenarios. In

Appreciable amounts of the world's energy supply are lost through the flaring of gas, and environmental monitoring requires that quantitative information be avilable. From data reported or estimated for 1968–1971 a regression line was fitted to cor

Nearly all scenarios for future U.S. energy supply systems show heavy dependence on coal. The magnitude depends on assumptions as to reliance on nuclear fission, degree of electrification, and rate of GNP growth, and ranges from 700 million tons to 2

During 1983, global emissions of CO2 from fossil fuels continued to decline slightly, to a value of 4932 millions tons carbon compared to 4957 million tons carbon in 1982. This marked the 4th consecutive year that CO2 emissions from fuel use has decl

A reference scenario for CO2 emissions was developed using a model of world energy supply and demand. In the reference scenario, world GNP and world energy demand increase at average rates of 2.1 percent per year and 1.5 percent per year, respectivel

Wood continues to be a major fuel source for vast numbers of the world's people. Even in the highly industrialized countries, use of wood and wood wastes as fuel produces a small (in comparison to fossil fuels) but non-negligible amount of CO2. Altho

Of all the fundamental physical considerations that enter into the determination of personal and collective energy policy, only one can be quantitatively addressed through thermodynamics: this is the minimal use of energy resources to achieve conserv

In addition to carbon dioxide there are a number of gases (e.g., N/sub 2/O, CH/sub 4/, CF/sub 2/Cl/sub 2/, CFCL/sub 3/, etc.) which could affect the radiation balance of the earth's atmosphere. Recent measurements indicate that the atmospheric concen

Although the evidence is quite clear that the increase in atmospheric CO2 is at least to a large degree a result of fossil fuel burning, and it is equally clear that this increase will result in some change in the global climate, there are quantitati
