350.org is a grassroots, international environmental organization started by founded by author Bill McKibben with the goal of building a global grassroots movement to raise awareness about human-driven climate change.
350.org takes its name from the research of Goddard Institute for Space Studies scientist James E. Hansen, who postulated that 350 parts-per-million (ppm) of CO2 in the atmosphere is a safe upper limit to avoid a climate tipping point. (Wikipedia)
The basic science of global warming can be summarized in three simple statements, which embody two indisputable scientific facts and the inevitable conclusion that follows from them:
Fact: Carbon dioxide is a greenhouse gas, by which we mean a gas that traps heat and makes a planet (like Earth or Venus) warmer than it would be otherwise.
Fact: Human activity, especially the use of fossil fuels — by which we mean coal, oil, and gas, all of which release carbon dioxide when burned — is adding significantly more of this heat-trapping gas to Earth’s atmosphere.
Inevitable Conclusion: We should expect the rising carbon dioxide concentration to warm our planet, with the warming becoming more severe as we add more carbon dioxide. [from Jeffrey Bennett's "A Global Warming Primer"]
Here's a 5-minute animation video that explains fracking.
Article explaining fracking by StateImpact, a Pennsylvania NPR collaborative between two stations. Thorough (but brief) article. Includes a link to Explore Shale: which has a very cool interactive page.
In Marcellus Shale sites in WV and PA, the average is 5 million gallons. (Between 2011 and 2013, drillers in Pennsylvania used about 11 billion gallons of water.)
That water is trucked to the site. How many truck loads? It depends of course on each truck’s capacity. The short answer: at least 1000 round trips to haul the water in, and then another 1000 round trips to haul the water out.
The long answer: see RESI's report, pages 93-100.)
When considering the water issue, remember that the people who live on the small local roads near fracking sites will be exposed to the persistent sounds and smells of these diesel trucks. Also, these small local lanes are not designed for the persistent volume and heavy loads.
In the fracking process, water is combined with chemicals and sand to make the hydraulic fracturing fluid. Under pressure, it is injected into the well. What happens to the water after the fracking occurs? It depends. Typically, the water is removed and hauled away from the fracking site.
Chemicals are used to reduce friction; biocides to prevent microorganism growth and to reduce biofouling of the fractures; oxygen scavengers and other stabilizers to prevent corrosion of metal pipes; and acids are used to remove drilling mud damage within the near‐wellbore area.
The fracking industry, in explaining the fracking process, will mention that chemicals are used, but they don't emphasize the quantity or type. They primarily emphasize that water and sand are used to do the fracking.
From marcelluscoalition.org: "...By setting a small charge, which perforates the casing and cement, we create the necessary opening in the casing to allow the hydraulic fracturing portion of the completions process to begin. The fracturing fluids – made up of more than 99.5 percent water and sand – is then injected under controlled high pressure to break open the formation, and expand and hold open the fractures, allowing the natural gas to flow to the well head."
Further on in the site “The number of chemical additives used in a typical fracture treatment depends on the conditions of the specific well being fractured. A typical fracture treatment will use very low concentrations of between 3 and 12 additive chemicals, depending on the characteristics of the water and the shale formation being fractured.”
"Very low concentrations" doesn’t sound so bad.
Do the math. 0.5% of 5 million gallons of water means 25,000 gallons of chemicals In another site, 2% is mentioned, which translates to 125,000 gallons of chemicals. ...pumped into the well under pressure.
What chemicals? “…additive chemicals” According to the EPA's briefing, Dec. 13, 2106 "Some chemicals in the hydraulic fracturing water cycle are known to be hazardous to human health. Of the 1,606 chemicals, 173 had chronic oral toxicity values..."
(See Chemicals Used in Pennsylvania)
Just a few from the list, in case you didn't click the link: Trimethylbenzene, Aromatic Ketones, Petroleum Naptha, Toluene, Xylene...) If you are curious about the potential hazards that these chemicals raise, here is link to the CDC's Pocket Guide to Hazardous Chemicals." Enter the chemical name, and the site returns a page of information.
If your household uses a well for its water, would you like these chemicals to be added to your water supply?
According to industry, fracking does not cause the earthquakes.
According to the U.S. Geological Survey, "...we do know that many earthquakes in Oklahoma have been triggered by wastewater fluid injection.” So not the actual fracking, but a separate part of the process. Maryland's proposed (but rejected) regulations had prohibited the injection of the wastewater, which takes us back to the trucking problem - the waste water has to be taken elsewhere. (Bloomberg)
Closer to home, on February 17, 2017, Pennsylvania's Dept. of Environmental Protection announced a correlation between eartquakes and fracing in Pennsylvania. Read more...

Sand is used in the fracking mix used to keep the fractures open. So what's wrong with using sand? Ask the people who live near sand mining operations. In Wisconsin and Michigan, a huge sand mining industry has developed to supply the fracking industry. During frac sand mining, crystalline silica is released into the air. It is a known carcinogen and can cause silicosis, an incurable lung disease that can lead to death.
Brief video from CBS News aired in 2014
OSHA Fact Sheet The people who live in areas where this sand mining occurs are physically impacted by this mining.
Some proponents of fracking argue that natural gas serves as a “bridge fuel” to use until we can use renewables more broadly. Burning carbon, whether coal or methane (natural gas), produces carbon dioxide (CO2) and water (H20). CO2 and H20 contribute to trapping heat in the earth’s lower atmosphere.
The problem is, whenever we burn, whatever we burn, we are increasing the amount of CO2 in the atmosphere.
Since industrialization, the concentration of CO2 has risen from about 280 parts per million (ppm) to over 400 ppm due to human activities. Many scientists, climate experts, and progressive national governments agree that 350 ppm is the “safe” level of carbon dioxide.  Watch a really good video from 350.org that explains the problem.
Whether climate change is man made or not is not the issue. More importantly, the question is, what can we do about it?

The Cove Point liquid natural gas (LNG) in southern Maryland is one of many LNG export facilities recently built or being built in the US. Financial analysts are optimistic that when these LNG export facilities come online, the domestic prices will rise.
Wouldn’t it be more sensible to keep the carbon source underground until we actually need it, instead of shipping it overseas?
Who benefits from this exporting? Not the residents of Cove Point, nor the residents throughout Maryland.
What happens when the fracked oil and gas is gone?
The owners of GAIL (India) Ltd. and ST Cove Point (a joint venture of units of Japanese trading company Sumitomo Corp and Tokyo Gas Co Ltd.) will surely benefit. Dominion sold the Cove Point project’s capacity for 20 years to them. Read more...
People with asthma who live near active unconventional natural gas wells operated by the fracking industry in Pennsylvania are 1.5 to four times likelier to have asthma attacks than those who live farther away, new Johns Hopkins Bloomberg School of Public Health research suggests.
The findings, published July 18 in JAMA Internal Medicine, add to a growing body of evidence tying the fracking industry to health concerns. Health officials have been concerned about the effect of this type of drilling on air and water quality, as well as the stress of living near a well where just developing the site of the well can require more than 1,000 truck trips on once-quiet roads. The fracking industry has developed more than 9,000 wells in Pennsylvania in just the past decade. Read more...
