For years, governments, industry, and TV ads told us natural gas is the safe bridge fuel while we move away from dirty coal and oil.
Cornell University scientist Robert Howarth wondered "Is that true?". When Howarth found no science to back up big claims for the gas industry, he and a team from Cornell went to work.
The results are startling. In the short-term, escaped methane from gas fracking threaten to tip us into catastrophic climate change. The total impact of the shale gas industry may be worse than coal. In the United States, where thousands and thousands of new gas wells are drilled, almost half of all greenhouse gas emissions may come from methane. The "natural" gas industry is the largest single source of methane emissions.
The frackers vent loads of gases for the first two weeks after drilling, before connecting pipes. They could collect (and sell) this "waste" methane (read "climate killer") but don't bother. Natural gas storage facilities also vent methane as part of their designed operation. Old leaking gas delivery systems complete the job.
Methane is rising in the atmosphere. New science from Dr. Drew Shindell shows in the first 20 years, methane is 105 times more powerful a greenhouse gas than CO2. Not 21, as determined in the 1990's by the IPCC. That old figure is still being used by industry and governments. Expect a change as Shindell becomes the new lead author of this section in the upcoming IPCC.
The industry insists we only calculate methane over a 100 year period. But the latest report from the International Energy Agency (generally a conservative source) says our climate future will be determined in the next 5 years. More new science suspects the burst of methane helped tip us into a mass extinction 250 million years ago.
The 20 year time frame for methane could be the jolt that tips other systems into positive feedback loops. Like igniting the peat in the Arctic. Or warming shallow seas enough to release frozen methane clathrates from the bottom (which started to happen last year). If either of those go, we are toast.
Robert Howarth has taken a lot of abuse for even daring to assemble a comprehensive look at the total greenhouse gas impact of the gas fracking industry, whether it is coal bed gas or shale gas. And we haven't even discussed the fact fracking is now known to cause earthquakes, uses incredible amounts of fresh water, and risks polluting whole watersheds with a single leak of the mass toxic chemicals pumped underground.
The United Kingdom may be next. With gas production from the North Sea fields down by 25 percent, there is a public relations push to get lots of gas fracking in the UK. This may be the next big environmental battle there.
Fracking mania has hit Canada and Australia as well. Everyone needs to know what the latest science says.
We add an interview promised last week, with Samuel Labudde, about the billion dollar scam ripping off carbon credits.
Companies in China are threatening to release powerful greenhouse gases, unless these fake credits are continued. Ratepayers in Europe are being blackmailed.
To honor the craziness of gas fracking in Australia, the theme music this week is "My Water's on Fire Tonight" written and performed by David Holmes, Andrew Bean, Niel Bekker. Australian compilation album: "Whole Lotta Frackin' Going On" at www.wholelottafrackingoingon.com

The new asbestos, government just letting it happen
This is the new asbestos and the government is just letting it happen. It's all about the money as usual. It makes me so sad. I read things like this and I really believe we all deserve to shrivel up - we are destroying our own backyards.
