Cornell University researchers factored in the carbon emissions over the course of natural gas's life cycle when it is extracted using hydraulic fracturing — which includes drilling the wells, erecting the construction sites, building pipelines to transport the gas, fueling the pumps that force the water underground, and transporting the wastewater — and concluded that natural gas is dirtier than coal.

These analyses indicate that it is likely that greenhouse gases alone would have caused more than the observed warming over the last 50 years of the 20th century, with some warming offset by cooling from natural and other anthropogenic factors, notably aerosols, which have a very short residence time in the atmosphere relative to that of well - mixed greenhouse gases (Schwartz, 1993).
