According to Tim Garrett, an associate professor of atmospheric sciences, University of Utah, rising carbon dioxide (CO2) emissions - the major cause of global warming - cannot be stabilized unless the world's economy collapses or society builds the equivalent of one new nuclear power plant each day.
Giving Up Beef Can Drastically Slow Down Global Warming!
Reports say India has urged Western countries to stop eating beef in order to cut greenhouse emissions.

The study, which is based on the concept that physics can be used to characterize the evolution of civilization, indicates that energy conservation or efficiency doesn't really save energy, but instead spurs economic growth and accelerated energy consumption.
"Stabilization of carbon dioxide emissions at current rates will require approximately 300 gigawatts of new non-carbon-dioxide-emitting power production capacity annually - approximately one new nuclear power plant (or equivalent) per day," Garrett said.
Global Warming may Not be Slowed by Reducing Greenhouse Gases
Reducing greenhouse gases may not be enough to slow down global warming, new research by a scientist at the Georgia Institute of Technology has determined.

Garrett said that his study's key finding "is that accumulated economic production over the course of history has been tied to the rate of energy consumption at a global level through a constant factor."

Global Warming may Spur Increased Growth in Pacific Northwest Forests
A new study has suggested that global warming in the next century could cause a significant increase in the productivity of high-elevation forests of the Pacific Northwest.

So, if you look at economic and energy production at any specific time in history, "each inflation-adjusted 1990 dollar would be supported by 9.7 milliwatts of primary energy consumption," Garrett said.

Then, he investigated the implications for carbon dioxide emissions.
"Economists think you need population and standard of living to estimate productivity," he said.
"In my model, all you need to know is how fast energy consumption is rising. The reason why is because there is this link between the economy and rates of energy consumption, and it's just a constant factor," he added.
"By finding this constant factor, the problem of forecasting global economic growth is dramatically simpler. There is no need to consider population growth and changes in standard of living because they are marching to the tune of the availability of energy supplies," said Garrett.
To Garrett, that means the acceleration of CO2 emissions is unlikely to change soon because our energy use today is tied to society's past economic productivity.
