More lunacy. A Washington policy outfit proposes that Americans work less to slow the progress of climate change.
A number of studies (e.g. Knight et al. 2012, Rosnick and Weisbrot 2006) have found that shorter work hours are associated with lower greenhouse gas emissions and therefore less global climate change. The relationship between these two variables is complex and not clearly understood, but it is understandable that lowering levels of consumption, holding everything else constant, would reduce greenhouse gas emissions.
This paper estimates the impact on climate change of reducing work hours over the rest of the century by an annual average of 0.5 percent. It finds that such a change in work hours would eliminate about one-quarter to one-half of the global warming that is not already locked in (i.e. warming that would be caused by 1990 levels of greenhouse gas concentrations already in the atmosphere).
It is worth noting that the pursuit of reduced work hours as a policy alternative would be much more difficult in an economy where inequality is high and/or growing. In the United States, for example, just under two-thirds of all income gains from 1973–2007 went to the top 1 percent of households. In this type of economy, the majority of workers would have to take an absolute reduction in their living standards in order to work less. The analysis in this paper assumes that the gains from productivity growth will be more broadly shared in the future, as they have been in the past.
The analysis uses four “illustrative scenarios” from the Intergovernmental Panel on Climate Change (IPCC), and software from the Model for the Assessment of Greenhouse-gas Induced Climate Change to estimate the impact of a reduction in work hours. As would be expected, the amount of global warming that could be mitigated by reducing work hours depends on the baseline scenario, as well as the range of sensitivity of global temperatures to greenhouse gas emissions.
The world will have to cope with some amount of climate change. Already, humans have released sufficient greenhouse gases into the atmosphere to raise the average surface temperature of the planet. Atmospheric concentrations will be high enough as to induce further warming for some time—even if emissions of greenhouse gases return to 1990 levels.
And so on. The zombie staggers on, everywhere you look.
