Earthquakes and Oklahoma: Wastewater Injection

The notion exists that "fracking" for natural gas or enhanced oil extraction directly caused the earthquakes observed in Oklahoma. There is some evidence for this, but by far the most likely cause is deep wastewater injection.

Sharp increase in central Oklahoma seismicity since 2008 induced by massive wastewater injection

K. M. Keranen, M. Weingarten, G. A. Abers, B. A. Bekins, S. Ge

Unconventional oil and gas production provides a rapidly growing energy source; however, high-production states in the United States, such as Oklahoma, face sharply rising numbers of earthquakes. Subsurface pressure data required to unequivocally link earthquakes to wastewater injection are rarely accessible. Here we use seismicity and hydrogeological models to show that fluid migration from high-rate disposal wells in Oklahoma is potentially responsible for the largest swarm. Earthquake hypocenters occur within disposal formations and upper basement, between 2- and 5-kilometer depth. The modeled fluid pressure perturbation propagates throughout the same depth range and tracks earthquakes to distances of 35 kilometers, with a triggering threshold of ~0.07 megapascals. Although thousands of disposal wells operate aseismically, four of the highest-rate wells are capable of inducing 20% of 2008 to 2013 central U.S. seismicity.

Some evidence and some publications have pointed to the simple act of fracking causing the problem, but the big culprit is wastewater injection. A similar cluster of earthquakes was seen in Denver in the late 1960s. http://earthquake.usgs.gov/research/induced/pdf/Healy-et-al-1968-Science-(New-York-NY).pdf

The distinction is important because if the US EPA quits giving the fracking industry a pass on deep wastewater injection, this all ends.

Discussionist is more ridiculous than I remembered.

Red-baiting:



Ok... but which of these men ever self-identified as a socialist? So, is it really "red-baiting"?

For most people, non-support for Sanders is a barometer of ...

... not fully embracing his policies.

Yes, he seems honest and consistent, but disagreeing with him is not an indication of mental illness*.

*EDIT: I'm not sure how one could misconstue this statement, but I am not suggesting Sanders is mentally ill. Please see this thread for context: http://www.democraticunderground.com/128010932

Climate Change Debate Fueled by ‘Echo Chambers,’ New Study Finds

Climate Change Debate Fueled by ‘Echo Chambers,’ New Study Finds

College Park, Md and Annapolis, Md — A new study from researchers at the University of Maryland (UMD) and the National Socio-Environmental Synthesis Center (SESYNC) demonstrates that the highly contentious debate on climate change is fueled in part by how information flows throughout policy networks.

The UMD and SESYNC researchers found that “echo chambers”—social network structures in which individuals with the same viewpoint share information with each other—play a significant role in climate policy communication. The researchers say that echo chambers may help explain why, despite a well-documented scientific consensus on the causes and drivers of global changes in climate, half of U.S. senators voted earlier this year against an amendment affirming that climate change is human-induced.

A peer-reviewed paper based on the study was published online May 25 in the journal Nature Climate Change.

“Our research shows how the echo chamber can block progress toward a political resolution on climate change. Individuals who get their information from the same sources with the same perspective may be under the impression that theirs is the dominant perspective, regardless of what the science says,” said Dr. Dana R. Fisher, a professor of sociology at UMD and corresponding author who led the research.

Keep in mind that it goes both ways -- denial as well as zealous declarations that every blip on the weather radar is due to climate change.

I would also submit that this kind of "echo chamber" approach exists for all environmental discussions -- GMOs, vaccinations, bees, whatever. Simple minded people will tend to keep the discussions "pure" by excluding those with different points of view, regardless of how valid they might be.

Marking Memorial Day

Who Invented Memorial Day?

As Americans enjoy the holiday weekend, does anyone know how Memorial Day originated?

On May 1, 1865, freed slaves gathered in Charleston, South Carolina to commemorate the death of Union soldiers and the end of the American Civil War. Three years later, General John Logan issued a special order that May 30, 1868 be observed as Decoration Day, the first Memorial Day — a day set aside “for the purpose of strewing with flowers or otherwise decorating the graves of comrades who died in defense of their country during the late rebellion, and whose bodies now lie in almost every city, village, and hamlet church-yard in the land.”

At the time, the nation was reunited politically, but it remained culturally divided, and so did Memorial Day observations. In the North, the federal government created national cemeteries for men who died in the war, while state governments from New York to Michigan gradually made Decoration Day an official holiday throughout the 1870s. In the South, from April to June, women dressed in white and knelt beneath statues of fallen Confederate leaders; they told stories about the men who appeared in portraits lining the walls of many Southern homes. By the early 20th century, as Americans faced enemies abroad, many of the surviving Civil War veterans recognized their shared wartime history and reconciled their differences — turning Memorial Day into a national holiday.

This is a good day to look past why wars were fought and to look to those who fell.

Does science have a liberal bias?

Everyone knows that the truth has a liberal bias.

---Stephen Colbert

Colbert's tongue-in-cheek declaration about the truth is too often taken literally by progressives. Partisanship being what it is, we often are convinced that the truth is on our side.

Is the same true of science? Do scientific facts support our liberal causes? Examples:
  • Global climate change (and the human influence)
  • Anti-GMO movement
  • Rejection of all pesticides
  • The dangers of nuclear energy
  • Anti-vaccinations

The answer, of course, depends upon your position on these issues. For example, although anti-vaxxers originate from within the left, progressives as a whole do not embrace the anti-vaccination stance, and the science tends to support vaccinations as being safe.

What is your attitude? Are you willing to accept scientific evidence -- scientific consensus -- when the science is contrary to the personal opinion that you passionately embrace?

Based on the dangers of GMOs discussed at DU, I see an opportunity:

From what I've read here at DU, we know for a fact that if we eat GMO food, the genetic modifications of the food can be transferred into our human genes and alter our DNA. We run the high risk of having unwanted traits passed on to us from Frankenfoods.

Actually, this isn't all bad, and it sounds like a fantastic opportunity. Let me tell you why: I recently saw a documentary about a young man who was bitten by a genetically modified spider. Some of the spider's genes were passed to the young man, and very soon he began developing spider traits like being able to cast webs, crawling up walls, and extraordinary strength and agility. I would like that to happen to me!

There is a dark side, and I guess that's the aspect that has everyone so frightened. In another instance, a man's DNA was fused with that of a fly, and the man eventually transformed into a six-foot tall fly. It was awful!

Anyway, I just wanted to thank everyone at DU for opening my eyes to the science of GMOs. Truly, a door has opened for me.

As if we needed a reminder: We are NOT in a post-racist America

From our sister site:

There are apparently still a sizable number of "N- - - - rs" out there..!!

Even though the vast majority of folks of African ancestry have successfully blended into our society, and have become responsible productive citizens, there appears a good deal of work still needing to be done !!
I suppose that it would be impossible to expect the total number of either race to act rationally..We whites have our own share of "scumbags" among our ranks, and expecting other races to not have their share also, would be irrational, but, both sides of the equation need to indeed work harder to try to reduce the numbers of the jerks that produce the mayhem we saw last night in Baltimore..

The perpetrators of such activities, truly still deserve to be referred to as the "N" word, regardless of their skin color!!

We've got a lot of work to do...Lets stop bickering about it, and get it FIXED...!!
