It is well documented that global temperature acceleration has significantly paused since 1998, despite the global CO2 emissions growth rate easily exceeding the business-as-usual (BAU) scenarios presented by NASA's James Hansen way back in 1988.
Yet the UN's Paris2015 proposed deep cuts in "dangerous" global CO2 emission growth rates will only delay "climate doomsday" by a laughable 8 months. And that would be accompanied by a likely debilitating economic impact of trillions of dollars - mostly suffered by the world's poor and most vulnerable.
The chart on left plots the most up-to-date 15-year average growth rates of CO2 emissions versus the global economy 15-year average growth rates. Surprisingly, as the GDP growth rate declines, on average, CO2 emissions growth just continues.
With that pointed out, it's also pertinent to point out that over the last 15 years the U.S. total emissions have actually shrunk, as well as those of the EU. In contrast, CO2 emissions for other major world economic regions have robustly increased over the last 15 years.
