And, of course, a hybrid or fuel-efficient car emits less carbon dioxide than an SUV.
Earth warming: Yes, carbon dioxide in the atmosphere is considered a cause of earth warming.
Without any checks and balances the cost of stanching carbon dioxide will be practically unlimited.
Chu said it is only a matter of time before the U.S. regulates carbon dioxide emissions.

Between 1945 and 1977, atmospheric carbon dioxide levels jumped rapidly, yet global temperatures declined.
Most powerfully, global temperature trends during the twentieth century sharply defied atmospheric carbon dioxide trends.
Temperature and carbon dioxide sensors can allow bulbs to deliver data to building management systems.

Better yet, the carbon dioxide in the exhaust gases could potentially be captured and buried underground.
Obama's big initiative will be some sort of cap-and-trade scheme for carbon dioxide emissions.
When measurements of carbon dioxide were first taken in 1958, it measured 315 ppm.
Back then, it took 7, 000 years for carbon dioxide to reach 80 ppm, Tans said.
The Mauna Loa station is the oldest in the world to measure carbon dioxide.
Driving to work leads to traffic congestion, an outrageous carbon dioxide output, not to mention headaches.
In other words, modern humans have never seen carbon dioxide in these proportions before.
But too much carbon dioxide, which leads to too much overall warming, is bad.
