Abstract:The Limits to Growth standard run scenario produced 40 years ago continues to align well with historical data that has been updated in this paper, following a 30-year comparison by the author. The scenario results in collapse of the global economy and environment, and subsequently the population. Although the modelled fall in population occurs after about 2030 – with death rates reversing contemporary trends and rising from 2020 onward – the general onset of collapse first appears at about 2015 when per capita industrial output begins a sharp decline. Given this imminent timing, a further issue this paper raises is whether the current economic difficulties of the global finan cial crisis are potentially related to mechanisms of breakdown in the Limits to Growth standard run scenario. In particular, contemporary peak oil issues and analysis of net energy, or energy return on (energy) invested, support the Limits to Growth modelling of resource constraints underlying the collapse, despite obvious financial problems associated with debt.

GAIA is a transdisciplinary journal for scientists and other interested parties concerned with the causes and analyses of environmental and sustainability problems and their solutions.
Environmental problems cannot be solved by one academic discipline. The complex natures of these problems require cooperation across disciplinary boundaries. Since 1991, GAIA has offered a well-balanced and practice-oriented forum for transdisciplinary research. GAIA offers first-hand information on state of the art environmental research and on current solutions to environmental problems. Well-known editors, advisors, and authors work to ensure the high quality of the contributions found in GAIA and a unique transdisciplinary dialogue – in a comprehensible style.
GAIA is an ISI-journal, listed in the Social Science Citation Index and in Current Contents/Social and Behavioral Sciences.
All contributions undergo a double-blind peer review.
