A TransCanada natural gas pipeline exploded and caught fire in the Canadian province of Manitoba on Saturday, sending flames up to 300 meters into the sky and cutting off gas supplies for 4,000 residents during sub-zero temperatures.

Gas is cleaner only at the point of combustion. If you calculate the greenhouse gas pollution emitted at every stage of the production process— drilling, piping, compression—it’s essentially just coal by another name.
New measurements made on one day suggest a need for more direct data
Cooperative Institute for Research in Environmental Sciences, August 5, 2013
“We expected methane emissions would be detectable, but we did not anticipate levels as high as what we observed,” said Colm Sweeney, a scientist with the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder, who leads the aircraft group at NOAA’s Earth System Research Laboratory Global Monitoring Division.

A 2011 study from the National Center for Atmospheric Research concluded that unless leaks can be kept below 2 percent, gas lacks any climate advantage over coal. And a study released this May by Climate Central, a group of scientists and journalists studying climate change, concluded that the 50 percent climate advantage of natural gas over coal is unlikely to be achieved over the next three to four decades. Unfortunately, we don’t have that long to address climate change — the next two decades are crucial.
Chemical analysis links methane in drinking wells to shale-gas extraction
Nature, Jeff Tollefson, June 25, 2013
“Jackson’s team found methane in 115 of the 141 shallow drinking-water wells that it sampled. The results suggest that home owners living up to 1 kilometre from shale-gas wells probably have groundwater contaminated by gas from the Marcellus Formation.”
Losses of up to 9% show need for broader data on US gas industry’s environmental impact
Nature, Jeff Tollefson, January 2, 2013
“Scientists are once again reporting alarmingly high methane emissions from an oil and gas field, underscoring questions about the environmental benefits of the boom in natural-gas production that is transforming the US energy system. The researchers, who hold joint appointments with the National Oceanic and Atmospheric Administration (NOAA) and the University of Colorado in Boulder, first sparked concern in February 2012 with a study suggesting that up to 4% of the methane produced at a field near Denver was escaping into the atmosphere. If methane — a potent greenhouse gas — is leaking from fields across the country at similar rates, it could be offsetting much of the climate benefit of the ongoing shift from coal- to gas-fired plants for electricity generation.”
Natural-gas operations could leak enough methane to tarnish their clean image
Nature, February 9, 2012
“These numbers, which are higher than estimates from Cornell and the US Environmental Protection Agency (EPA), should serve as a red flag to the gas industry, policy-makers and the academic community.“

“The International Energy Agency has just issued a special report titled, “Are We Entering a Golden Age of Gas?” The answer to that question is “yes” only if you are a natural gas producer who doesn’t care much about humanity. For the rest of us, the report makes clear natural gas by itself does nothing to avert catastrophic climate change. Quite the reverse.”
