Its not my SUV...it's the Ocean

About 13,000 and 18,000 years ago, carbon dioxide poured into the atmosphere in two giant belches that drove concentrations of the greenhouse gas from 180 to 265 parts per million, where it held relatively steady until the Industrial Revolution.

Thomas Marchitto, a marine geologist at the University of Colorado, Boulder, and a lead author of the new study, said matching the rise of old water to the atmospheric changes provides strong evidence that the gas came from the ocean.

The burps injected 700 billion tons of carbon dioxide into the atmosphere. They occurred at a time when Earth already was emerging from an ice age. What started the warming is unknown, but scientists said the release of the gas accelerated it.Over a 10,000-year span, global temperatures rose by more than 7 degrees Fahrenheit.

Since my Suburban was built in 2002, I am pretty sure it has nothing to do with Global Warming that occurred 18,000 years ago.
