Gas Well Blowout at Porter Ranch, California Sickening Residents

Posted by feww on December 29, 2015

Monster Gas Leak Spewing up to 50,000 kg/hr of  powerful GHG

The massive gas leak at a natural gas storage well at Aliso Canyon storage field in Northridge, California, operated by SoCalGas, has released about 75,000 metric tons of methane since it was discovered on October 23, 2015.

The leak is currently spewing about 33,000 – 50,000 kg/hr of the GHG, which is said to be the equivalent of a quarter of the state’s total methane emissions from all sources.

The emissions are making the residents sick. Thousands of the residents have experienced nausea, dizziness, vomiting, nosebleeds, and headaches among other symptoms from the hazardous gas.

Some 6,500 families have filed for help, but only about 2,250 have since been relocated, with another 100 or so staying with family or friends.


New video shot with a highly specialized Optical Gas Imaging camera shows time-lapse image of Southern California Gas Co.’s Aliso Canyon gas leak. Video depicts an ominous cloud of methane gas flowing down from the gas well over the community of Porter Ranch. The video shows the gas cloud at 60x speed. For more information visit: http://porterranchlawsuit.com/

Relocating Schools

The Board of Education took action last week to expedite the temporary relocation of Castlebay Lane Charter and Porter Ranch Community School, comprising a total of about 1,900 students, due to disruptions in teaching and learning caused by the methane leak in Aliso Canyon.

“When classes resume after the winter break, the 770 students in grades K-5 who attend Castlebay Lane will be relocated to Sunny Brae Avenue Elementary in Winnetka. Porter Ranch Community School, which has 1,100 students in grades K-8, will relocate to Northridge Middle School. Portable classrooms and available space at the host schools will be used to house the Castlebay Lane and Porter Ranch students, teachers and staff.”

SoCalGas in Aliso Canyon, outside of Los Angeles, has released the following in its latest report on the blowout.

Relief Well  [BPesque?]

Efforts to drill the relief well are progressing. Crews are actively working on Phase 3 of a 5 phase process. This potentially time consuming phase is critical to the overall success, and encompasses positively identifying the leaking well with active magnetic ranging technology. Once identified, the relief well will follow the leaking well to more than 8,000 feet deep and intercept it near its bottom. Once we intercept the well, we will pump heavy mud and fluids into the leaking well to stop the flow of gas from the reservoir and into the well. Once the flow of gas has been stopped, we will pump cement into the bottom of the well to permanently seal it. The drilling process continues around the clock, and is expected to be completed by late February to late March.

As of December 27, we have successfully located the leaking or target well using the active magnetic ranging tool and are preparing to resume drilling.  We have currently drilled approximately 3,800 feet of measured depth.  From this point on, we will be interchanging drilling and ranging equipment as needed to increase the precision of the relief well in relation to the target well’s location and to follow it down at the appropriate distance, angle and orientation.

We are also initiating a secondary relief well as backup to our ongoing drilling of the primary relief well. Grading of the drilling pad for the secondary well should be complete in early January.  At that point a drilling rig will be moved in and set up.  Drilling is slated to begin in late January.

Amazon Deforestation Climbed 28 Percent in 12 Months

Posted by feww on November 15, 2013

5,843 km² of Brazil forest denuded in 12 months to July 2013

Deforestation rate in Brazil rose to 5,843 km² between August 2012 and July this year, a staggering rise of 28%, compared with the previous period, according to provisional figures released by the government.

More than 600,000 km² of Amazon rainforest have been destroyed in the past 40 years to make room for cattle ranching, farming and extensive transportation projects.

Agriculture accounts for almost 5.5% of the Brazil’s GDP, and is responsible for the majority of Brazil’s greenhouse gas emissions.


Cattle rest in deforested jungle near Maraba, in Brazil’s central state of Para, May 3, 2009.  Soon thousands of cows will be chewing pasture on the freshly cleared land in Brazil’s Amazon state of Para, just a tiny part of Brazil’s 200-million-strong commercial cattle herd, the world’s biggest, that makes it a beef superpower. More than 70 million are in the Amazon area, three for every person. This is where the industry has grown fastest in recent years, a trend activists say is due to cheap land, widespread illegal clearing and weak government enforcement. REUTERS/Paulo Whitaker.

Total Atmospheric CO2e: 4,024.78 Gt

CO2 at Mauna Loa (weekly average)

Week of May 22, 2011: 394.97 ppm

  • Weekly value from 1 year ago:   393.06 ppm
  • Weekly value from 10 years ago:   373.93 ppm

Based on the above data, total atmospheric CO2 TODAY:

3,081,994,507,051.11 Mt [3,082Gt]

Combined impact of Nitrous Oxide (N2O), Methane (CH4) and CFC 12 ( CCl2F2) calculated at their full global warming potential: 30.59% of the CO2 Impact, or the CO2 equivalent of

942,782,119,706.94 Mt CO2e [942 Gt CO2e]

Effective Total: 4,024.78 GtCO2e

[MT: Metric Tons;  Gt: Gigatons; CO2e: Carbon Dioxide Equivalent; ppm: parts per million by volume]

Trends in Atmospheric Carbon Dioxide (ESRL)

The graph, updated weekly, shows as individual points daily mean CO2 up to and including the week (Sunday through Saturday) previous to today. The daily means are based on hours during which CO2 was likely representative of “background” conditions, defined as times when the measurement is representative of air at mid-altitudes over the Pacific Ocean. That air has had several days time or more to mix, smoothing out most of the CO2 variability encountered elsewhere, making the measurements representative of CO2 over hundreds of km or more. The selection process is designed to filter out any influence of nearby emissions, or removals, of CO2 such as caused by the vegetation on the island of Hawaii, and likewise emissions from the volcanic crater of Mauna Loa. For details, see ”How we measure background CO2 levels at Mauna Loa”. The same measurement principles also apply elsewhere. The weekly mean (red bar) is simply the average of all days in the week for which a background value could be defined. The average standard deviation of day to day variability, calculated as the difference from the appropriate weekly mean, equals 0.38 ppm for the entire record. As a visual aid, the blue lines present monthly means of background data as they are presented under Recent Monthly CO2 at Mauna Loa. These data are still preliminary, pending recalibrations of reference gases and other quality control checks. Image and Caption: ESRL.  Click images to enlarge.


This figure shows the atmospheric increase of CO2 over 280 ppm in weekly averages of CO2 observed at Mauna Loa. The value of 280 ppm is chosen as representative of pre-industrial air because it is close to the average of CO2 measured and dated with high time resolution between the years 1000 and 1800 in an ice core from Law Dome, Antarctica. [Etheridge et al., 1996]. Although the time resolution of old air locked in ice cores is not enough to preserve seasonal cycles, there is no doubt that the seasonal cycle, which is mostly caused by photosynthesis and respiration of ecosystems on land, was similar to what we observe today. Therefore, for the comparison with pre-industrial times the Mauna Loa weekly data have been first deseasonalized by subtracting the observed average seasonal cycle, and then subtracting 280 ppm. The enhancement of the CO2 mole fraction in the atmosphere over pre-industrial is expressed both as ppm and as a percentage change since the year 1800. Data are reported as a dry air mole fraction defined as the number of molecules of carbon dioxide divided by the number of all molecules in air, including CO2 itself, after water vapor has been removed. The mole fraction is expressed as parts per million (ppm). Example: 0.000400 is expressed as 400 ppm.  Image and Caption: ESRL 

CO2 emissions reach a record high in 2010

Energy-related carbon-dioxide (CO2) emissions in 2010 broke all previous records, according to the latest estimates by the International Energy Agency (IEA).

Recent Mauna Loa CO2

The graph shows recent monthly mean carbon dioxide measured at Mauna Loa Observatory, Hawaii.


The last four complete years of the Mauna Loa CO2 record plus the current year are shown. Data are reported as a dry air mole fraction defined as the number of molecules of carbon dioxide divided by the number of all molecules in air, including CO2 itself, after water vapor has been removed. The mole fraction is expressed as parts per million (ppm). Example: 0.000400 is expressed as 400 ppm.

In the above figure, the dashed red line with diamond symbols represents the monthly mean values, centered on the middle of each month. The black line with the square symbols represents the same, after correction for the average seasonal cycle. The latter is determined as a moving average of SEVEN adjacent seasonal cycles centered on the month to be corrected, except for the first and last THREE and one-half years of the record, where the seasonal cycle has been averaged over the first and last SEVEN years, respectively.

The last year of data are still preliminary, pending recalibrations of reference gases and other quality control checks. The Mauna Loa data are being obtained at an altitude of 3400 m in the northern subtropics, and may not be the same as the globally averaged CO2 concentration at the surface.   Image and Caption: ESRL

Full Mauna Loa CO2 record


Monthly mean atmospheric carbon dioxide at Mauna Loa Observatory, Hawaii –
The carbon dioxide data (red curve), measured as the mole fraction in dry air, on Mauna Loa constitute the longest record of direct measurements of CO2 in the atmosphere. They were started by C. David Keeling of the Scripps Institution of Oceanography in March of 1958 at a facility of the National Oceanic and Atmospheric Administration [Keeling, 1976]. NOAA started its own CO2 measurements in May of 1974, and they have run in parallel with those made by Scripps since then [Thoning, 1989]. The black curve represents the seasonally corrected data.

Data are reported as a dry mole fraction defined as the number of molecules of carbon dioxide divided by the number of molecules of dry air multiplied by one million (ppm).  Image and Caption: ESRL    -Data Set Available HERE

How Big is Your CO2 Dome?

Posted by feww on March 17, 2010

Urban CO2 domes increase deaths

Public release: Stanford University

Everyone knows that carbon dioxide, the main greenhouse gas driving climate change, is a global problem. Now a Stanford study has shown it is also a local problem, hurting city dwellers’ health much more than rural residents’, because of the carbon dioxide “domes” that develop over urban areas. That finding, said researcher Mark Z. Jacobson, exposes a serious oversight in current cap-and-trade proposals for reducing emissions of heat-trapping gases, which make no distinction based on a pollutant’s point of origin. The finding also provides the first scientific basis for controlling local carbon dioxide emissions based on their local health impacts.

“Not all carbon dioxide emissions are equal,” said Jacobson, professor of civil and environmental engineering. “As in real estate, location matters.”

His results also support the case that California presented to the Environmental Protection Agency in March, 2009, asking that the state be allowed to establish its own CO2 emission standards for vehicles.

Jacobson, director of the Atmosphere/Energy Program at Stanford, testified on behalf of California’s waiver application in March, 2009. The waiver had previously been denied, but was reconsidered and granted subsequently. The waiver is currently being challenged in court by industry interests seeking to overturn it.

Jacobson found that domes of increased carbon dioxide concentrations – discovered to form above cities more than a decade ago – cause local temperature increases that in turn increase the amounts of local air pollutants, raising concentrations of health-damaging ground-level ozone, as well as particles in urban air.

In modeling the health impacts for the contiguous 48 states, for California and for the Los Angeles area, he determined an increase in the death rate from air pollution for all three regions compared to what the rate would be if no local carbon dioxide were being emitted.

The results of Jacobson’s study are presented in a paper published online by Environmental Science and Technology.

The cap-and-trade proposal passed by the U.S. House of Representatives in June 2009 puts a limit on the amount of greenhouse gases that each type of utility, manufacturer or other emitter is allowed to produce. It also puts a price tag on each ton of emissions, which emitters will have to pay to the federal government.

If the bill passes the Senate intact, it will allow emitters to freely trade or sell their allowances among themselves, regardless of where the pollution is emitted.

With that logic, the proposal prices a ton of CO2 emitted in the middle of the sparsely populated Great Plains, for example, the same as a ton emitted in Los Angeles, where the population is dense and the air quality already poor.

“The cap-and-trade proposal assumes there is no difference in the impact of carbon dioxide, regardless of where it originates,” Jacobson said. “This study contradicts that assumption.”

“It doesn’t mean you can never do something like cap and trade,” he added. “It just means that you need to consider where the CO2 emissions are occurring.”

Jacobson’s study is the first to look at the health impacts of carbon dioxide domes over cities and his results are relevant to future air pollution regulations. Current regulations do not address the local impacts of local carbon dioxide emissions. For example, no regulation considers the local air pollution effects of CO2 that would be emitted by a new natural gas power plant. But those effects should be considered, he said.

“There has been no control of carbon dioxide because it has always been thought that CO2 is a global problem, that it is only its global impacts that might feed back to air pollution,” Jacobson said.

In addition to the changes he observed in local air pollutants, Jacobson found that there was increased stability of the air column over a city, which slowed the dispersal of pollutants, further adding to the increased pollutant concentrations.

Jacobson estimated an increase in premature mortality of 50 to 100 deaths per year in California and 300 to 1,000 for the contiguous 48 states.

“This study establishes a basis for controlling CO2 based on local health impacts,” he said.

Current estimates of the annual air pollution-related death toll in the U.S. is 50-100,000.

Three giant 8.5-meter (26ft) high waves bashed against a cruise ship in the Mediterranean, as if trying to rip it apart, killing two people and injuring  six others.

The Cypriot-owned Louis Majesty was sailing off the north-east coast of Spain when the “abnormally high” waves attacked, breaking ship windows,  shipowners were reported as saying.

“A wave broke the glass in the area of the saloon and water was taken on board,” a spokesman for the Spanish coast guard confirmed.

The dead weer identified as a German and an Italian male, both in their fifties.  There were 1,350 passengers and 580 crew onboard.

The Louis Majesty was on a 12-day Mediterranean cruise headed toward Genoa, Italy, but has since returned to Barcelona, Spain.

“Louis Cruises extends its sincere condolences to the families of the two victims and its full support to the injured passengers while expressing its deep sorrow for the incident,” a company spokesman said.

Winds of more than 100km per hour (60 mph) in the area may have been responsible for the incident a French Navy official was reported as saying.

Do you feel as if nature has put you on notice?

Who is afraid of melting ice sheets?

Posted by feww on April 18, 2009

Based on its outdated “one-dimensional” model, the U.N. Climate Panel has reported that seas could rise by 18-59 cm  (7-24 inches) by 2100. The model also excludes the threat from highly probable scenarios in which ice sheets in Antarctica and Greenland could melt at exponential rates.

Ian Allison, head of  the Australian Antarctic Division’s Ice, Ocean, Atmosphere and Climate program was asked by Reuters the following question: How great is the threat from melting ice sheets?

Allison who is a researcher within the Antarctic Climate and Ecosystems Cooperative Research Center, and who has been involved in Antarctic science for more than 4 decades, responded as follows.

HOW GREAT IS THE THREAT FROM ICE SHEETS MELTING?

I think it is now unequivocal that warming of the world is occurring and I think the last IPCC (Intergovernmental Panel on Climate Change) conclusively showed that a major cause of warming is greenhouse gas emissions from mankind.

We now know that the ice sheets are contributing to sea level rise and for the Arctic, at least, this is because the warming of this region is much greater than in other places on Earth.

We also know that glaciers in mountain areas are undergoing a very rapid retreat and they’re a major contributor of sea level rise, too.

WHICH IS OF MORE CONCERN? GREENLAND OR WEST ANTARCTICA?

Greenland is of more concern because of the warming of the Arctic. Greenland is at lower latitude than much of Antarctica and we’ve seen the direct effect of the melting.

We still don’t understand many things about the dynamic response of the ice sheets but we do see direct melt exceeding snowfall in Greenland.

This might not mean a runaway effect but it does mean Greenland is contributing to sea level rise and will continue to add to sea levels at the present temperatures for many hundreds of years.”

EXPLAIN THE THREAT FROM WEST ANTARCTICA

Ice shelves and floating ice tongues can buttress the flow of grounded ice from the interior of the ice sheets. We’ve seen examples in both Greenland and Antarctica of floating ice disappearing, and the ice that sits on the land then flowing more quickly into the ocean.

“In addition, the West Antarctic may be inherently unstable. The West Antarctic forms what is called the marine ice shelf. The ice is resting on bedrock but that bedrock is below sea level. It’s like if you load too many ice cubes in your gin and tonic, the bottom one touches the bottom of the glass even though it’s well below the water level.

Where the bedrock under a marine ice sheet slopes down toward the interior, such as under parts of West Antarctica, the ice sheet may be unstable. If it thins, it will start to float at the edges, becoming an ice shelf.

For a bedrock that slopes backwards and becomes deeper further in, continued retreat of the grounded ice sheet may proceed very rapidly. A small retreat could in theory destabilize the entire West Antarctica ice sheet, leading to rapid disintegration.

WHAT ARE THE MAIN GAPS IN OUR KNOWLEDGE?

There two areas. One, we need to improve our mathematical models of ice streams, ice sheets and ice shelves to be able to better project future changes. We also need more detailed measurements of how deep the bedrock is under the ice sheets to use in the models.

The other major gap in our understanding is what is happening at the bed of the ice sheets; how they react with liquid water at the base, what role water may have in sliding processes and the role of gravels and slurry at the base.

We now know there is a lot of liquid water under the ice sheets. But we don’t really know how changes in this may affect the ice flow. Knowing what’s under the ice sheets we really need to measure that with radar systems.

WHAT ARE YOUR MAIN MESSAGES TO POLICY MAKERS?

The main thing is monitoring what’s actually happening with sea level rise and the ice sheets. We’ve now got tools that can do that, we can improve those and make sure they keep going, particularly satellite-based systems.

We need better predictive tools to know just what is likely in the next 100 years. I don’t think we should be rushing into building up coastal defenses until we know what we could be defending against. So our biggest requirement is to be able to refine our projections for what may happen in the future. (Edited by David fox).

“The first action that people should take is to use the democratic process. What is frustrating people, me included, is that democratic action affects elections but what we get then from political leaders is greenwash.

“The democratic process is supposed to be one person one vote, but it turns out that money is talking louder than the votes. So, I’m not surprised that people are getting frustrated. I think that peaceful demonstration is not out of order, because we’re running out of time.” James Hansen, NASA climatologist, said.

Corporate lobbying is undermining democratic attempts to reduce CO2 pollution. “The democratic process doesn’t quite seem to be working,” he said.

4.5 times more NF3 in atmosphere than thought

Posted by feww on October 24, 2008

Scripps News Release
Scripps Institution of Oceanography

Potent Greenhouse Gas More Prevalent in Atmosphere than Previously Thought

NF3, a greenhouse gas used in manufacture of computer displays, flat panel televisions, microcircuits, solar panels is 17,000 times more powerful at warming the atmosphere than carbon dioxide

Scripps Institution of Oceanography/UC San Diego

Nitrogen trifluoride (NF3), a powerful greenhouse gas, is about 4.5 times more prevalent in the atmosphere than previously thought, say researchers at Scripps Institution of Oceanography at UC San Diego.

[A 3-d Space-filling model of nitrogen trifluoride. ]

Nitrogen trifluoride (NF3), a potent greenhouse gas used in the plasma etching of silicon wafers, has a global warming potential (GWP) 17,000 times greater than CO2 over a 100 year period, and with an estimated atmospheric lifetime of about 750 years.

Atmospheric measurements of nitrogen trifluoride (NF3) were made using new analytical techniques by a team at Scripps shows that the amount of the gas in the atmosphere in 2008 was about 5,400 metric tons, 4.5 times higher than previously thought,  and was increasing at about 11 percent per year.

Geochemistry professor Ray Weiss who lead the research team said: “Accurately measuring small amounts of NF3 in air has proven to be a very difficult experimental problem, and we are very pleased to have succeeded in this effort.”

The research will be published in Geophysical Research Letters, a journal of the American Geophysical Union (AGU) on October 31.

Previously, emissions of NF3 were considered too low to be a significant contributor to global warming and were therefore omitted from the Kyoto Protocol, the agreement to reduce greenhouse gas emissions signed by 182 countries in 1997.

Environmental Impact of NF3 Gas at Current levels

  • NF3 is about 17,000 times more effective a global warming agent than an equivalent mass of CO2.
  • Persists five times longer in the atmosphere than carbon dioxide.
  • [Fortunately] Contributes only about 0.04 percent [at its current application levels] to the overall global warming caused by the anthropogenic carbon dioxide emissions.

Nitrogen trifluoride has been the industries’ preferred alternative to perfluorocarbons, also potent greenhouse gases, as it was thought industrial applications broke down about 98 percent of the NF3 and only about 2 percent of the gas escaped into the atmosphere.  (Source)

“We thought that it was Jesus who had come back”

Folks, it ain’t Jesus; it’s Human-induced climate change. Ask your local teacher to tell you about the effects of GHG Emissions!

The ferocious storm in Busara, about 260 km northwest of the capital, Nairobi, turned parts of central Kenya white with a massive hailstorm.

“We thought a big white sheet had been spread, so we decided to come and see for ourselves. We thought that it was Jesus who had come back,” a villager said.

“The hailstones falling on the ground joined together to form expansive sheets of ice or snow flakes occupying a large area, 30 acres,” meteorologists said. the storm was caused “the convergence of cold air currents from the Indian Ocean and warm air currents from the Congo.”

“In fact this thing is very sweet, we have never seen anything like this. We like the ice so much because with the sun being hot, you take it and you feel satisfied,” another villager said.

Kenya straddles the equator. “The only snow to be seen in normally sunny Kenya is on top of the country’s highest mountain, 5,199-meter (17,057 ft) Mount Kenya.” Reuters said.

Global Warming Tolls the Death Knell for Tuvalu

Massive tides, high winds and rising sea levels are causing erosion to the four reef islands and five true atolls that comprise the tiny country of Tuvalu.


Map of Tuvalu

Formerly known as the Ellice Islands, the low-lying Polynesian islands are located in the Pacific Ocean midway between Hawaii and Australia. The nine-island cluster contains 600 sq km of ocean, but only a total of 25 sq km of land.

“The residents of Tepuka Savilivili, an island 10 kilometers away from Funafuti, also sense the crisis. One day in 1997, an uninhabited island simply vanished. The residents explained that gale winds blew and covered the island during the night. The next day, the coconut trees had vanished.” Wrote Nam Jong-yeong.

Drinking water is mixing with salty ocean water; the coconut trees are vanishing; during high tides seawater covers most parts of the islands.

Thousands of Tuvaluans have already left the shrinking islands, most of them arriving in what they believe to be a safe destination: New Zealand.

Their new home, however, could breakup and sink in the south-western Pacific Ocean as a result of massive earthquakes. It’s rather like jumping out of the frying pan into the fire!

Direct action protesters try to stop UK coal-fired power plant for a day

About a 1,000 climate protesters, who aimed to stop the output at Kingsnorth coal-fired power station for a day, demonstrated outside the plant in southeast England on Saturday.

Nearly 2,000 police and civilian security personnel surrounded the protesters. Police in riot gears brandishing batons charged at the protesters and arrested about 50 people.

“We just want to try and send a message to people that we don’t want any more new coal … it’s something that’s not going to help our future at all,” said Helen Atkinson, 26, a medical photographer from Cumbria, northwest England. (Source)

Southern Ocean Carbon Sink

Posted by feww on July 2, 2008

From NASA’s Earth Observatory:

Southern Ocean Carbon Sink

If you drove to work or school this morning or used electricity to power the computer on which you’re looking at this image, chances are you released carbon dioxide, a greenhouse gas, into the atmosphere. According to the Intergovernmental Panel on Climate Change, people released about 7.8 billion tons (7.8 gigatons) of carbon into the atmosphere in 2005 by burning fossil fuels and making cement, and that number grows every year. What happens to all of the carbon dioxide that people release into the atmosphere? About half stays in the atmosphere, where it warms Earth, and the other half is absorbed by growing plants on land and by the ocean.

As people have put more and more carbon dioxide into the atmosphere, the ocean has responded by soaking up more carbon dioxide—a trend scientists expected to continue for many years. But in 2007, a team of scientists reported in the journal Science that between 1981 and 2004 carbon dioxide concentrations in the Southern Ocean didn’t change at all, even though global atmospheric levels continued to rise. This graph shows the changes scientists expected to see (blue line) compared to their estimate of actual carbon dioxide absorption (red line). The results suggested that the Southern Ocean was no longer keeping pace with human carbon dioxide emissions.

Why has the Southern Ocean started to lag behind human emissions? The answer, believes Corinne Le Quéré, is in the wind. An ocean scientist at the University of East Anglia, Le Quéré led the study that discovered the Southern Ocean’s change of pace. Le Quéré modeled the mechanisms that influence how the ocean takes up carbon and found that winds increased between 1981 and 2004. Winds stirred the ocean and enhanced the upwelling of deep, carbon-rich water. The ocean releases carbon dioxide into the atmosphere in areas where deep water comes to the surface, so increased upwelling allowed the ocean to vent more carbon dioxide. This increased venting made it look like the Southern Ocean was no longer taking up carbon dioxide as quickly as people were pumping it into the atmosphere.

Is 350 ppm Safe? Hell, NO!

Posted by feww on June 24, 2008

Folks, don’t be fooled by the hype: 350 ppmv NOT safe!

  1. There is a 30-year time lag between the release of CO2e greenhouse gases to the atmosphere and the cumulative impact of heat-trapping mechanism taking effect.
  2. The positive feedback system whose impacts we are now witnessing started when the atmospheric CO2 concentration rose above the 330 ppmv in the mid 1970s.
  3. Any concentration level above the 330 ppm is clearly unsafe. To stabilize at levels below 330 ppm, we must aim for much lower levels of about 260-270 ppm.

Mississippi Levees Breached in 23 Places

Posted by feww on June 20, 2008

A Shrinking World Series

‘We are seeing a historic hydrological event taking place with unprecedented river levels occurring.’ —Brian Pierce, meteorologist, National Weather Service.

Mississippi river surges over at least 23 levees and another 30 barriers are at risk, as the Midwest floods move south.

In 1993, devastating floods, sweeping down Missouri and Mississippi rivers, surged levees and destroyed communities from St. Louis to northern Louisiana.

Midwest Flood Victims Feel Misled by Feds

“They all told us, `The levees are good. You can go ahead and build,”‘ said Parks, who did not buy flood coverage because her bank no longer required it. “We had so much confidence in those levees.”

“People put all their hopes in those levees, and when they do fail, the damage is catastrophic,” said Paul Osman, the National Flood Insurance Program coordinator for Illinois. “New Orleans is the epitome; a lot of those people didn’t even realize they were in a floodplain until the water was up to their roofs.”

“We reported to the president in ’94 that the levee system was in disarray, the levees were not high enough to take care of any potential problem. People didn’t understand their flood risk and there wasn’t good co-ordination across federal, state and local governments,” said Gerald Galloway, a professor of engineering and flood control expert.

“The same thing applies today,” Galloway said. “It’s amazing that in the face of [Hurricane] Katrina and now this particular challenge that we continue to relearn the same lessons.”

Galloway’s recommendations to improve the levee system were basically ignored. He said that he’s experiencing much the same response now from officials as in 1993.

Environmental Disasters: Too Close for Comfort?

Posted by feww on June 14, 2008

submitted by a reader

“You ain’t seen nothing yet!”

Beginning to feel that the environmental disasters are getting up close and personal?

One minute you are in your comfortable home near Paradise, north of Sacramento, the next minute you are being consoled by the firefighters as you stand in the front garden watching your home turn into blackened cinder. They apologize for failing to help you, but it wasn’t their fault. They ran out of water!

Wondering why?

Five hours and a dozen phonecalls later, you are finally heading to the calm of Wisconsin to stay with Cousin Thelma and her family. Turn the radio on. Homes on Lake Delton in central Wisconsin have been ripped apart by deadly storm and washed away by floodwaters. Chilly gooseflesh grow on your forearms. Something tingles deep inside your gut, that uncomfortable feeling something is wrong. And you are right! Well, It’s Friday the 13th, you hear yourself murmuring.

Back to Iowa to stay with an old classmate who lives in Marshal Town, Iowa, and who invited you to visit her last summer. A rain check is as good as … a rain check! Finally you arrive in Marshal Town. But the whole town has been evacuated and the power plants have been shut down!

Well, at least you have the good old, reliable SUV, and it’s not as if the world is running out of corn to make ethanol for you!

Bering Sea Drilling Revisited!

Posted by feww on June 13, 2008

Update: Bush to urge lifting of ban on offshore drilling
“With gasoline now over $4 a gallon, tomorrow he will explicitly call on Congress to also pass legislation lifting the congressional ban on safe, environmentally friendly offshore oil drilling,” White House spokeswoman Dana Perino said on Tuesday.

Offshore Drilling

The following post is a reply to Dan Daniels who recently visited this blog and left a comment at Bering Sea Drilling .

Dan Daniels wrote:

I was the District Manager for Sedco Forex responsible for exp[l]oration activities on the West Coast of the US including the Bering Sea. I had two semi-submersible drilling vessels working in the Bering Sea when environmental concerns required us to cease drilling activities.

In the 8 plus years we, as a company, operated in this area we NEVER had an environmental issue (not so much as a st[y]rofoam cup going over the side) – this with daily high scrutiny from the Department of the Interior. I even received an award on behalf of our company for this accomplishment.

I believe strongly that with proper controls, commitment from management, training and overview offshore drilling can be accomplished without detriment to the environment. The issue lies almost exclusively with shipping the product, not developing the field. We should make every effort to carry out the require exploration and focus our efforts on improving the transportation aspects of moving the petroleum products


An offshore Oil/Gas platform.

Mr Daniels,

We [the FEWW moderators] believe the problems are much more extensive than you have stated. The areas of greatest concern are

  1. Impacts of excessive energy consumption.
  2. Climate Change.
  3. Other impacts of excessive CO2 and other GHG pollution created by the consumption of fossil fuels, e.g., oceans acidification.
  4. Marine pollution, habitat destruction and other damage caused by offshore oil and gas drilling including
  • Exploration
  • Production
  • Transportation
  • Storage
  • Delivery

The specific items of concern include:

  • Flaring and venting
  • greenhouse gas emissions
  • Decommissioning of oil and gas installations
  • oil storage tank disposal
  • Pollution created by drill cuttings
  • Produced waters, muds and fluids
  • Subsidence
  • Spills
  • piping
  • Environmental impact of products
  • Health impact of processes in products
  • Spoilage of sensitive ecological areas and habitat destruction
  • Waste disposal
  • Health impact of processes in products
  • Impact on Marine Mammals and other life forms
  • Human Health Impact
  • Climate Change
  • Release of benzene, methanol, sulfur and other harmful chemicals to the environment
  • Discharge of ballast waters
  • Release of tank cleaning water
  • Impact on ecosystems

The following excerpts are from Sense and Nonsense:The Environmental Impacts of Exploration on Marine Organisms Offshore Cape Breton, by David Lincoln.

Sense and Nonsense

The environmental impacts of the Oil and Gas Industry’s exploration operations are pervasive. No country or province which has been exposed to a prolonged history of offshore hydrocarbon exploration has been left untouched by the inevitable accidents and unforeseen consequences of the petroleum industry.

The fishing industry is usually the first sector to be impacted by these exploration activities. This normally occurs when fishermen are told to remove their boats and gear from an area so that a seismic vessel can begin generating noises.

By far the loudest noises generated by the offshore petroleum industry are those produced by seismic survey equipment. This equipment is designed to create very loud noises, the echoes of which reflect off geological strata deep within the seabed and are used to locate likely places for drilling wells. The sounds were at one time made by explosives, which could kill fish at a range of some hundreds of meters, but the almost universal seismic equipment now used offshore is an array of “airguns”.

Seismic Effects on Fish and Marine Mammals

Experiments on the effects of seismic shooting on abundance and catch of cod and haddock were conducted in the Barents Sea. The Norwegian studies looked at the effects of an airgun using a combination of scientific-survey and commercial fishing techniques. The fish survey work extended across a circle 40 nautical miles in diameter (a maximum range of some 33 km from the airgun survey area) and continued until five days after the seismic work was completed..”

Since the fall of the Iron Curtain, information has begun to flow out about the Russian experience with decades of exploration activity in the Caspian and Barents Seas. These reports differ markedly from the rather subdued observations in Western Bloc countries. Dr Stanislav Patin in his 1999 book entitled “Environmental Impacts of the Offshore Oil and Gas Industry” recalls a catastrophic ecological situation in the Caspian Sea in the 1960’s. “I was a member of the Special Government Committee on this issue and witnessed firsthand the dramatic ecological consequences of the explosive use, including mass mortality of Caspian sturgeons (up to 200,000 large specimens).”

Exploration Drilling

Despite industry claims, the companies do not yet know for certain which type of hydrocarbon (oil, gas, condensate or a combination of these fluids. will be encountered). Vintage seismic data from the 1980’s cannot accurately distinguish between oil and gas and geochemistry, if available, is often difficult to interpret. Before drilling, the companies will conduct a hazard survey primarily to reduce the chances of encountering shallow gas which could be disastrous.

Shallow seismic surveys of the upper few hundred meters of the seabed are often carried out to determine the structure of the sediments and scan for potential hazards to drilling (e.g., shallow gas pockets). These hazards will be described in greater detail in the section on shallow gas blowouts.

The Drilling Phase

Under normal circumstances, the predominant discharges during drilling, would be the “cuttings”; small chips of rock cut by the drill in forming the well, and the “muds” used in the drilling process to cool and lubricate the drill, carry the cuttings out of the hole and counter-balance the pressure of gas, when that is reached. These discharges, their fates and their environmental effects have been the most intensively studied (and argued) aspect of the offshore petroleum industry’s environmental effect.

Mud and Cuttings Discharges: Water Based Muds (WBMs)

Besides their intended constituents, drill muds, both Water Based Muds (WBMs) and Oil Based Muds (OBMs), often contain high levels of heavy metal contamination. WBMs, despite their water base, also often contain appreciable amounts of oil: under some circumstances, it is necessary to add a “pill” of oil to the circulating WBM and this is usually left in the mud, gradually being dispersed through it and ultimately discharged
with it.

The overall quantities of WBM discharged can be high. While the water naturally disperses into the ocean, the other constituents represent substantial contamination. The eight exploratory wells drilled with WBM on Georges Bank in 1981-2, for example, resulted in some 4000 tons of barite and 1500 tons of bentonite clay being discharged.

Water-Based Mud

The composition of drilling mud may be changed often during drilling in response to conditions encountered. In practice, this usually means that mud weight is gradually increased by adding barite and other chemicals to control the natural pressure increase with depth. When this happens suddenly, the mud is dumped in bulk and a new batch is mixed (often with heavier properties in anticipation of increased pressure). Analysis of the drilling waste scenario data (volume density and weight) could yield a likely
composition. It is indeed strange that adult scallops are highly sensitive to barite but show relatively low sensitivity to used water based mud cuttings.

Furthermore, dozens of organisms have already been subjected to varying compositions of drilling mud and the toxicity results are known and well reported. Of 415 acute lethal bioassays lasting 48-144 hrs with 68 drilling muds involving 70 species, 8% showed 50% mortality (LC50) below 10,000 ppm.

Ecosystem Impacts

“There is concern that the routine discharge of wastes during drilling for oil and gas could impact valuable fishery resources. Recent studies have indicated that intensive drilling efforts in the North Sea have caused detrimental effects in adult and larval fish and benthic invertebrates at greater distances from drilling platforms than previously envisaged”.

Abundance of benthic organisms near one N.J. rig site plunged from 8011 animals /sqm before drilling to 1729 animals /sq m. during drilling. One year after drilling was completed, the number had risen to only 2638 animals /sq m. Diversity was also impacted from 70 to 38 species /0.02 sq m rebounding only to 53 species /0.02 sq m one year afterwards.

Discharges and Shellfish

Laboratory experiments have shown barium uptake, from WBM-contaminated sediments and foods, by both flounder and lobster juveniles but there does not seem to be any evidence for its biomagnification up the food chain. In the experimental setting, the contaminants suppressed growth of both species and enhanced lobster mortality but this was with concentrations of 9 g barium per kilogram of sediment and a 98 or 99-day …

Certainly, its finer grain size should ensure that it is at least as mobile as the barite and probably more so. Recent research has shown that scallops are peculiarly susceptible to barite and bentonite, prolonged exposure to even concentrations as low as 10 mgl-1 (less than 10 ppm) being fatal, while levels as low as 2 mgl-1 can affect scallop growth.

“As mush as 90% of the discharged solids settle directly to the bottom. (Brandsma 1980). The remaining 10% including clay-sized particles and soluble materials is diluted by the current and dispersed over large areas8. ” Furthermore “during the entire [one well] scenario a total of 468 MT of drilling mud and 2569 MT of cuttings are released to the marine environment.

Now that it has been shown that drilling eight wells spread detectable levels of barite over much of Georges Bank, the COPAN drilling near Sable Island spread flocculant material some kilometers from the source, Norwegian oil production has affected benthic communities over some 100 sq km around major platforms and that background sediment hydrocarbon levels seem to be rising in the United Kingdom sector of the North Sea, the relevance of such impacts can no longer be ignored.

Shallow Gas Blowouts

One of the greatest risks to the environment during the exploration phase is a shallow gas blowout. This is particularly true if the flow is associated with a condensate discharge which frequently occurs. […] Once flow has started, it is almost inevitable that a blowout will occur.

“Cratering occurs when flow outside the casing displaces large volumes of surface sediment. The eruptive force of blowouts can be dramatic and has been documented as lifting large boulders weighing several hundred pounds into the air and dropping them as much as 150 ft from the well site.

“Records show that if a shallow gas blowout does not bridge within the first one to two days, then the well will probably continue to blow for an extended period of time, i.e., weeks or months. Some have continued for years.”

Adams includes a chart condensed from a database of 950 shallow gas blowouts. Of the 56 rigs listed more than half suffered extensive damage or the total loss of the rig.

The truth is that the biological impacts of gas and condensate spills have been poorly studied until recently. Even the Uniacke gas blowout which released condensate in 1984 was not evaluated for biological impacts. Gas blowouts such as occurred in India in 1999 are poorly reported and not studied in detail. It is ludicrous for the industry to argue that gas wells have little impact on the ecosystem when they have not looked carefully at the marine organisms effected and no long-term studies on productivity or reproductive success following exposure are known to exist.

Oceans, Where Life Started, Are Dying – Part IV

Posted by feww on May 26, 2008

Wild Facts Series: Just when you thought the oceans were dying painlessly!

Carbon Emissions Make Oceans Corrosive!

‘Acidified’ Water Threatens Marine Life on the Continental Shelf from Canada to Mexico: NOAA

Researchers found evidence of corrosive water about 20 miles off the west coast of North America from Canada to Mexico last summer. The ocean water on the western North American continental shelf was previously thought not to be “acidified.”

“Ocean acidification” is caused by the ocean’s absorption of carbon dioxide (CO2) from the atmosphere, a process which makes water corrosive.

“Acidification of the Earth’s ocean water could have far-reaching impacts on the health of our near-shore environment, and on the sustainability of ecosystems that support human populations through nourishment and jobs,” said Richard W. Spinrad, NOAA assistant administrator for oceanic and atmospheric research. “This research is vital to understanding the processes within the ocean, as well as the consequences of a carbon-rich atmosphere.”

“Our findings represent the first evidence that a large section of the North American continental shelf is seasonally impacted by ocean acidification,” said Feely. “This means that ocean acidification may be seriously impacting marine life on our continental shelf right now.”

“While this absorption provides a great service to humans by significantly reducing the amount of greenhouse gases in the atmosphere and decreasing the effects of global warming, the change in the ocean chemistry affects marine life, particularly organisms with calcium carbonate shells, such as corals, mussels, mollusks, and small creatures in the early stages of the food chain,” said Feely.

NOAA said: “Previous studies found ocean acidification at deeper depths farther from shore. The researchers said that the movement of the corrosive water appears to happen during the upwhelling season during the spring and summer, when winds bring CO2 -rich water up from depths of about 400-600 feet onto the continental shelf. The water that upwells off of the North American Pacific coast has been away from the surface for about 50 years.

The field study collected samples from Queen Charlotte Sound, Canada, to San Gregorio Baja California Sur, Mexico. The closest they found corrosive water was about four miles off of the northern California coast.”

“We did not expect to see this extent of ocean acidification until the middle to the end of the century,” said Sabine. “Because of this effort, we have a baseline for future observations as we continue to study and monitor the relationship of biological and physical processes and their ability to respond to ocean acidification.”

“We did not expect to see this extent of ocean acidification until the middle to the end of the century,” said Sabine. “Because of this effort, we have a baseline for future observations as we continue to study and monitor the relationship of biological and physical processes and their ability to respond to ocean acidification.”

“When the upwelled water was last at the surface, it was exposed to an atmosphere with much less CO2 than today and future upwelled waters will probably be more acidic than today’s because of increasing atmospheric CO2,” said Hales, a professor of chemical oceanography, who is also funded by NASA.

“We don’t know how this will affect species living in the zone below the level of the lowest tides, out to the edge of the continental shelf,” said Ianson, an oceanographer. “We do know that organisms like corals or pteropods are affected by water saturated with CO2. The impacts on other species, such as shellfish and other juvenile fish that have economic significance, are not yet fully understood.”

“In Baja California, we have several Mediterranean-climate coastal lagoons where the main external physical and biogeochemical forcing is from the neighboring coastal ocean, strongly influenced by upwelling,” said Hernandez-Ayon, a coastal oceanographer. “We are concerned about these areas because they play an important role as nurseries and feeding grounds of juvenile fish populations but are also are ideal sites for shellfish aquaculture.” More …

What is Bleaching?

Corals are very sensitive to temperature change: a 1–2º C change in local temperature above their normal summer maximum can lead to a phenomenon called ‘bleaching’, whereby the corals expel their vital algal symbionts (algae which live in the cells of the coral), leaving the coral tissues translucent.


Bleached Coral (Pocillopora) NOAA’s Pacific Islands Fisheries Science Center of the National Marine Fisheries Service.

In 1998, a single bleaching event led to the loss of almost 20% of the world’s living coral. Corals can recover from these events but repeated episodes are likely to weaken the coral ecosystem, making them more susceptible to disease and causing a loss of biodiversity. (Source)

How will ocean acidification affect marine life?

Corals, calcareous phytoplankton, mussels, snails, sea urchins and other marine organisms use calcium (Ca) and carbonate (CO3) in seawater to construct their calcium carbonate (CaCO3) shells or skeletons. As the pH decreases, carbonate becomes less available, which makes it more difficult for organisms to secrete CaCO3 to form their skeletal material. For animals in general, including invertebrates and some fish, CO2 accumulation and lowered pH may result in acidosis, or a build up of carbonic acid in the organism’s body fluids. This can lead to lowered immune response, metabolic depression, behavioral depression affecting physical activity and reproduction, and asphyxiation. Since the oceans have never experienced such a rapid acidification, it is not clear if ecosystems have the ability to adapt to these changes (1,2). Effects of ocean acidification on organisms and ecosystems are still poorly understood. Over the last few years, research has intensified significantly to fill the many knowledge gaps. (Source)
