Major cuts to surging CO2 emissions are needed now, not down the road, study finds
Date:1/7/2013

Irvine, Calif., Jan. 7, 2013 Halting climate change will require "a fundamental and disruptive overhaul of the global energy system" to eradicate harmful carbon dioxide emissions, not just stabilize them, according to new findings by UC Irvine and other scientists.

In a Jan. 9 paper in Environmental Research Letters, UC Irvine Earth system scientist Steve Davis and others take a fresh look at the popular "wedge" approach to tackling climate change outlined in a 2004 study by Princeton scientists Stephen Pacala and Robert Socolow. They had argued that the rise of dangerous CO2 could be stopped using existing technologies by dividing the task into seven huge but manageable "slices."

Davis and his co-authors conclude that while the approach has great merit, it's not working, and it's not enough.

"We have enormous respect for that earlier work," he said. "But almost a decade after 'wedges' made a solution to climate change seem doable, we now know that holding emissions steady, difficult as it would be, is literally a half-measure and one that we have yet to take. Our emissions are not being held constant or even slowing; they're growing faster than ever."

The 2004 plan involved such tactics as doubling the number of nuclear reactors worldwide and increasing automotive fuel efficiency from an average of 30 mpg to 60 mpg. Each "wedge," if accomplished, would after 50 years avoid 1 billion tons of carbon per year and seven wedges combined, Pacala and Socolow estimated, would prevent the worst effects of climate change.

However, Davis and fellow authors of the new paper calculated that as many as 31 wedges could be required to stabilize Earth's climate at safe CO2 levels and that sharp reductions in total emissions would have to begin much sooner than half a century from now.

"We need new ways to generate the vast quantities of power that we now use worldwide," he said. "Current technologies and
