In fact the only upside of all this is that the massive slow-down in economic growth will rapidly cut the growth rates of CO2 emissions. Pollution is tightly linked to the level of economic activity, so that a few years of negative growth would lead to reductions in pollution levels not seen since the 1970s. It seems ironic that the greed of Wall Street may have inadvertently achieved what millions of well intentioned scientists, activists and politicians have failed to achieve – a slowdown in global warming.
