Human Population and Carbon Dioxide

A recently proposed model of human population and carbon utilization is reviewed. Depending on parameter values, one of three possible long-term outcomes obtains. 1. Atmospheric carbon, [CO2]atm, and human populations equilibrate at positive values. 2. The human population stabilizes, while [CO2]atm increases without bound. 3. The human population goes extinct and atmospheric carbon declines to...

Carbon dioxide kinetics and capnography during critical care

Greater understanding of the pathophysiology of carbon dioxide kinetics during steady and nonsteady state should improve, we believe, clinical care during intensive care treatment. Capnography and the measurement of end-tidal partial pressure of carbon dioxide (PETCO2) will gradually be augmented by relatively new measurement methodology, including the volume of carbon dioxide exhaled per breat...

Stationarity of Global Per Capita Carbon Dioxide Emissions: Implications for Global Warming Scenarios

Annual global CO2 emission forecasts at 2100 span 10 to 40 billion tonnes. Modeling work over the past decade has not narrowed this range nor provided much guidance about probabilities. We examine the time-series properties of historical per capita CO2 emissions and conclude that per capita global emissions are stationary without trend, and have a constant mean of 1.14 tonnes per person with st...
