Global Circulation Models (GCMs) provide projections for future climate warming using a wide variety of highly sophisticated anthropogenic CO2 emissions scenarios as input, each based on the evolution of four emissions “drivers”: population p, standard of living g, energy productivity (or efficiency) f and energy carbonization c (IPCC WG III 2007). The range of scenarios considered is extremely broad, however, and this is a primary source of forecast uncertainty (Stott and Kettleborough, Nature… Expand

The implications of fossil fuel supply constraints on climate change projections: a supply-side analysis
Abstract Climate projections are based on emission scenarios. The emission scenarios used by the IPCC and by mainstream climate scientists are largely derived from the predicted demand for fossilExpand
Past world economic production constrains current energy demands: Persistent scaling with implications for economic growth and climate change mitigation
The contribution of inertia to future trends is described, finding a constant scaling between current rates of world primary energy consumption E(t) and the historical time integral W of past world inflation-adjusted economic production Y, which implies that current growth trends in energy consumption, population, and standard of living are determined by past innovations that have improved the economic production efficiency.

Identification of a 50-year scaling relating current global energy demands to historically cumulative economic production
Abstract. Global economic production, or the GDP, has risen steadily relative to world primary energy demands, suggesting technological change is driving a gradual decoupling of society from itsExpand

No way out? The double-bind in seeking global prosperity alongside mitigated climate change
Abstract. In a prior study (Garrett, 2011), I introduced a simple economic growth model designed to be consistent with general thermodynamic laws. Unlike traditional economic models, civilization isExpand

Global and regional drivers of accelerating CO2 emissions
Global emissions growth since 2000 was driven by a cessation or reversal of earlier declining trends in the energy intensity of gross domestic product (GDP) and the carbon intensity of energy (emissions/energy), coupled with continuing increases in population and per-capita GDP. Expand
Origins and estimates of uncertainty in predictions of twenty-first century temperature rise
It is found that, in the absence of policies to mitigate climate change, global-mean temperature rise is insensitive to the differences in the emissions scenarios over the next four decades and that in the future, as the signal of climate change emerges further, the predictions will become better constrained.
