Sorry but...so what? Oil has been around for millions of years - we just didn't posess the technology to use it or see it's value.
I have discussed this subject a few times when I've had the opportunity to talk to a friend's son - who works as a geologist for a major oil company. The last time I spoke to him on this subject, his perspective was that the only areas of the world where there are large tracts that have not been mapped for oil and gas development, are in the Arctic Ocean and the Antarctic Continent (and even much of those regions are already explored). The imaging or mapping technology available to geologists is getting more accurate, and able to provide clearer projections of how large oil and gas fields are; but development has waited until more accessible oil and gas was recovered.
Once again, it's a matter of going after the low-hanging fruit first. Development of oil and virtually all other natural resources, becomes dirtier and more energy-intensive as extraction continues to the less desirable product.
But, then there is the point that I forgot to advance yesterday, which also should be addressed by everyone with the "live for today" attitude: if oil and other natural resources are used up in a few short decades by an increasingly rapacious civilization, what are the moral implications for leaving future generations with nothing but a hotter, polluted and degraded world to deal with and fight for survival?
No thanks. Though the movie is well regarded from an artistic point of view, it's well known that it is also scientifically inaccurate and agenda -driven.
All I know is that when I hold a match up to water coming out of my kitchen tap, it doesn't catch fire!
This is all very interesting but I wasn't discussing natural gas as a transportation fuel. I said "energy source." It is a viable source of energy with many uses. And it's natural - unlike nuclear energy, for instance.
And abundant.
The first time I heard of fracking was when T Boone Pickens was running around promoting windmills and running cars and trucks on natural gas. It's as a transportation fuel that most of the fracking-promoters push for development....and in the few applications so far where natural gas has been used to power trucks and buses, it's been an expensive waste of time.
And, how is nuclear not as "natural" as gas?
Maybe some people are shocked, but I'm not. With my husband's career depending on oil and gas, he and I stay as informed as possible.
In fact, he's currently working in the Marcellas shale. If you are truly interested in how oil and gas companies implement policies and practices in order to protect the environment, maybe you could write out your specific questions and I can pass them along to him to address. As an oilfield consultant with over 30 years of experience in fracking, he is a good source of first hand information.
Okay, maybe you could ask him if he's familiar with
this study published by two Cornell University professors - reported in Scientific American a few days ago, which claims that hydraulic fracking releases uncontrollable amounts of "fugitive" methane into the air:
Robert Howarth, an ecologist and evolutionary biologist, and Anthony Ingraffea, a civil and environmental engineer, reported that fracked wells leak 40 to 60 percent more methane than conventional natural gas wells. When water with its chemical load is forced down a well to break the shale, it flows back up and is stored in large ponds or tanks. But volumes of methane also flow back up the well at the same time and are released into the atmosphere before they can be captured for use. This giant belch of "fugitive methane" can be seen in infrared videos taken at well sites.
Add to the equation, the fact that methane levels in the atmosphere are also rising.
Level of Heat-Trapping CO2 Reaches New High, Growth Rate Speeds Up, Methane Levels Are Rising Again
This may be due largely from the burning of tropical forests and the progressive melting of Arctic permafrost, but a massive push into natural gas fracking will add even more methane to the atmosphere. Add to this that we are learning - thanks to Dr. Drew Shindell of NASA's Goddard Space Institute - that the greenhouse effects of methane gas in the atmosphere are greater than the standard projection used in the IPCC reports, and last much longer than projected in the IPCC, because of what happens as methane combines with other air pollutants. Even at 100 years, Shindell finds methane is combining with other air pollution to generate an impact 33 times more powerful than CO2:
Aerosols make methane more potent: NatureDrew Shindell, at NASA Goddard Institute for Space Studies, New York, and colleagues ran a range of computerized models to show that methane's global warming potential is greater when combined with aerosols atmospheric particles such as dust, sea salt, sulphates and black carbon.
The International Panel on Climate Change (IPCC) and treaties such as the Kyoto Protocol assume methane to be, tonne-for-tonne, 25 times more potent than carbon dioxide at warming the planet. But the interaction with aerosols bumps up methane's relative global warming potential (GWP) to about 33, though there is a lot of uncertainty around the exact figure. In the Kyoto Protocol, GWPs are used to govern emissions trading. "This study is saying those GWPs should be revisited because they're leaving out an important thing," says Shindell.
Technology continues to advance, and supply and demand will continue to force us to develop and implement new innovations for energy sources, including but not limited to tar sands, gas shales, etc.
The "forcing" is done by economic expectations, which it needs to be added, have not improved the wellbeing of the vast majority of people. It's interesting to note that polls on personal satisfaction have shown a steady drop since the 1950's, along with a steady rise in dissatisfaction, depression over the years....all at a time when prosperity was supposed to be increasing! So, who is benefiting from the frenzy of increased consumption and increasing resource and energy use? A step back reveals the modern way of life to resemble a crack addict, who is being sickened and will eventually die from his addiction, yet wants more and more of the drug!
For the record, I agree that our research and development of energy sources should NOT be limited to what we know to be a finite energy source (fossil fuels). That would be incredibly stupid and short sighted.
Certainly! But I would propose that ALL energy and economic development needs to be weighed through the lens of how they impact the environment. Everything we do, all of the new inventions, political theories about how to run a government, are all a waste of time if they continue the path to destruction.
Be cautious when reading up on this topic - there's lots of hyperbole and exxageration out there from a wide variety of sources.
I am cautious; but most of the disinformation has come from the side that wants to develop potentially lucrative energy sources. While on a conservative forum, I was treated to one report after another coming from oil-funded front groups that picked at parts of IPCC reports on climate change. On average, most IPCC projections have been overly conservative, and have underestimated the increase in greenhouse gas levels, average global temperatures, the melting of permafrost and sea ice in the Arctic etc. (that new analysis on effects of methane mentioned earlier would be yet another example), yet a small number of climatologists who work on behalf of oil, and the expensive effort to propagate their confusing message in the media, has successfully stopped any serious attempts by the U.S., Canadian, and Australian governments as well as many others, to take action.
There is a lot of money in oil and gas extraction, as can be witnessed from last years' income statements that put seven large oil conglomerates among the top ten most profitable corporations in the world. The disinformation campaigns run by the oil companies, starting back in the 80's, have wasted precious time to steer our world away from turning into a hotter planet that will be difficult for future generations to adjust to and survive.
There are huge advances in ecological protection. For instance, my husband is working with a research and development company that is developing a method to clean and recycle the water used in fracking operations. I can't say more about it at this point, but let's just say it's very exciting and will probably be implemented in 2012. This is a huge step toward continuing to improve safety standards and practices and typical of the ongoing focus on protecting our environment, which is, contrary to some "sources" actually very important to the vast majority of oil and gas companies.
That sounds good! But, while cleaning water used in fracking would lessen the environmental impacts locally, that methane problem is still hanging over this development....let alone the fact that natural gas is merely "the cleanest" of fossil fuels, not devoid of having a carbon footprint itself. A switch from oil and coal to mostly natural gas would slow the rates of human-caused greenhouse gas increases, but it would not serve as a permanent solution to the problem.
