The Only Thing That Will Stop Global Warming Is A Massive Economic Downturn [View all]

A new report from the University of Michigan starts off its press release with a not so optimistic phrase: “It’s a message no one wants to hear.”

Just what message is this?

That it would take an extreme economic downturn to slow the effects of global warming.

The research conducted by José Tapia Granados and Edward Ionides of U-M and Óscar Carpintero of the University of Valladolid in Spain is considered the first to assess fluctuations in carbon dioxide based on measurable levels, instead of less accurate carbon emission estimates.

“If ‘business as usual’ conditions continue, economic contractions the size of the Great Recession or even bigger will be needed to reduce atmospheric levels of CO₂,” Tapia Granados, a researcher at the U-M Institute for Social Research, said in a statement (via Science Daily).

Global warming: New research emphasizes the role of global economic growth

Tapia Granados and colleagues found no observable relation between short-term growth of world population and CO₂ concentrations, and they show that recent incidents of volcanic activity coincided with global recessions, which brings into question the reductions in atmospheric CO₂ previously ascribed to these volcanic eruptions.

In years of above-trend world GDP, from 1958 to 2010, the researchers found greater increases in CO₂ concentrations. For each trillion in U.S. dollars that the world GDP deviates from trend, CO₂ levels deviate from trend about half a part per million, they found. Concentrations of CO₂ were estimated to be 200-300 ppm during preindustrial times. They are presently close to 400 ppm, and levels around 300 ppm are considered safe to keep a stable climate.

To break the economic habits contributing to a rise in atmospheric CO₂ levels and global warming, Tapia Granados says that societies around the world would need to make enormous changes.

"Since the 1980s, scientists like James Hansen have been warning us about the effects global warming will have on the earth," Tapia Granados said. "One solution that has promise is a carbon tax levied on any activity producing CO₂ in order to create incentives to reduce emissions. The money would be returned to the population on a per capita basis so the tax would not mean any extra fiscal burden."
