Laughable AGU Claim: 2011 Tōhoku earthquake and tsunami 'spurred global warming'

WASHINGTON, D.C. – Buildings destroyed by the 2011 Tohoku earthquake released thousands of tons of climate-warming and ozone-depleting chemicals into the atmosphere, according to a new study.

New research suggests that the thousands of buildings destroyed and damaged during the 9.0 magnitude earthquake and tsunami that struck Japan four years ago released 6,600 metric tons (7,275 U.S. tons) of gases stored in insulation, appliances and other equipment into the atmosphere.

Emissions of these chemicals, called halocarbons, increased by 21 percent to 91 percent over typical levels, according to the new study accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union.

First look

The study is the first to look at how the Tohoku earthquake affected the release of halocarbons into the atmosphere and likely one of the first to examine emissions of these gases following a natural disaster, according to the study’s authors.

“What we found is a new mechanism of halocarbon emissions coming from the earthquake,” said Takuya Saito, a senior researcher at the National Institute for Environmental Studies in Tsukuba, Japan, and lead author of the new paper.

Halocarbons released as a result of the earthquake include chemicals that deplete the ozone layer and contribute to global warming – including some gases that are no longer used because of those harmful effects on the environment. These include chlorofluorocarbons like CFC-11, a powerful ozone-depleting chemical used in foam insulation until it was phased out in 1996, and hydrochlorofluorocarbons like HCFC-22, an ozone-depleting refrigerant that is also a powerful greenhouse gas and is in the process of being phased out of use. Among other halocarbons released by the earthquake were hydrofluorocarbons, or HFCs, and sulfur hexafluoride, both potent greenhouse gases.

The emissions of the six halocarbons released from Japan in 2011 are equivalent to the discharge of 1,300 metric tons (1,433 U.S. tons) of CFC-11 alone — equal to the amount of CFC-11s found in 2.9 million refrigerators manufactured before the chemical was banned. The total emissions of the six chemicals are also equivalent to the release of 19.2 million metric tons (21.2 million U.S. tons) of carbon dioxide into the atmosphere – an amount equal to about 10 percent of Japanese vehicle emissions in 2011, according to the study’s authors.

Post-quake surprise

Saito and his colleagues decided to investigate halocarbon emissions and their relationship to the earthquake after ground-based air monitoring stations in Japan recorded surprising high levels of these chemicals. The stations are on Hateruma Island, east of Taiwan; Cape Ochiishi, on the east side of Hokkaido; and Ryori, north of Tokyo on Honshu.

The study’s authors combined these measurements with an atmospheric model and other mathematical methods to figure out that increased emissions from the earthquake were involved, how much of the emissions could be attributed to the disaster and how they compared to previous years.

They found that emissions of all six halocarbons were higher from March 2011 to February 2012, following the earthquake, than they were during the same time the year before the event and during the same period the year after it.

About 50 percent of the halocarbon emissions after the earthquake were of HCFC-22, likely due to damage to refrigerators and air conditioners. Emissions of the gas were 38 percent higher than the years before and after the earthquake. Emissions of CFC-11 were 72 percent higher than emissions before and after the earthquake, likely due to damage to insulation foams used in appliances and buildings, according to the study. Emissions of two types of HFCs — HFC-134a and HFC-32 — rose by 49 percent and 63 percent compared to the years before and after the disaster.

Impacts assessed

The new study also calculates the total impact of the increased emissions on ozone depletion and global warming. The earthquake-triggered surge of halocarbons increased ozone loss from Japanese emissions of those six gases by 38 percent* from March 2011 to February 2012 compared to the same time period in the years before and after the event. The amount of heat trapped in the atmosphere because of Japan’s emissions of those six gases rose 36 percent from March 2011 to February 2012 compared to earlier and later years because of the extra emissions from the earthquake, according to the new study.

Saito said the new study shows the importance of including the release of gases from natural disasters in emissions estimates. Although the global effect of one event is small — emissions associated with the Tohoku earthquake accounted for 4 percent or less of global emissions in 2011 — the cumulative effect could be larger, he said. Natural disasters accelerate the release of halocarbons and replacement of these gases could lead to the use of more halocarbons, according to the study.

National halocarbon emissions estimates by the Japanese government did not factor in the release of the chemicals due to the earthquake and are likely underestimating the amount of these substances in the atmosphere, according to Saito. Governments rely on inventories of chemicals and generic data about how they are used to estimate their amounts in the atmosphere – called a “bottom-up” approach” — whereas the new study uses actual measurements of the gases – called a “top-down” approach. “It is apparent that there are unreported emissions,” Saito said.

The new study shows that there could be a need to include the amount of halocarbons released by catastrophic events in emissions estimates, said Steve Montzka, a research chemist at the National Oceanic and Atmospheric Administration in Boulder, Colorado, who was not involved in the research. It also highlights the need for more measurements of halocarbons in the atmosphere, he added, rather than relying on bottom-up emissions estimates from inventories.

“Atmospheric scientists often say that relying solely on bottom-up inventories to tell you how greenhouse gas emissions change is like going on a diet without weighing yourself,” Montzka said.

Pope Pius XII excommunicated all Italians who vote for communists to save Italy for the establishment, so why can’t the modern-day Pope excommunicate all Catholics who breathe out more than they breathe in? It’s the out-breath that releases CO2, not the in-breath. It’s about time the planet was saved from those dirty Out-breathers! start with one group of people and spread the new planet-saving regime! Another plus would be politicians [and alarmists] who spoke less would be showing their genuine commitment to saving the planet!

There is very little difference between a metric tonne & an Imperial ton, around 16kg more for a metric tonne. 1 tonf (force) = 1.016 tonnes f (force). Personally I wouldn’t worry which landed on me, the outcome would be the same, a rather slimmer AtB! 😉

From http://vspages.com/ton-vs-metric-ton-6068
“Ton and metric ton are weight measure units. However, there is a difference. Metric ton is equal to 1000 kilograms and is SI unit. Hence, it is a megagram as it contains 1 million grams. The term ton is comes from Latin word tunna which means cask and in the past a cask filled with things usually weighed almost a metric ton.
A metric ton is not the same as short ton which is used in the United States. Ton used in the United States equals to 2,000 pounds, or approximately 907 kg. The long ton (tonne) is equals to 2240 pounds. However it is not commonly used in the United States.”

Me too. For some reason I reversed the cause and effect in the blog post title. I thought it was coming back to something from a few years ago claiming the force exerted by typhoons downward via storm surge on the seafloor could trigger earthquakes and global warming IF it was found to produce increased cyclonic storms COULD, POSSIBLY, MAYBE with a 97% confidence level trigger more earthquakes & tsunamis IF that effect were true.

As with most man made global warming scenarios it is not the direct emissions that is of importance. Obviously the direct input of greenhouse gases was very small in this case. It is the positive feedback that is an issue. The emissions from this earthquake will trigger another which will trigger another at an ever increasing rate, finally reaching the point it will tear the Earth apart. 🙂

As a comparison, equatorial volcanic eruptions can, if explosive enough, cause robust, season-dependent distinctive weather patterns across Europe. Compare that observed and modeled phenomenon to the present study and one might determine the voracity of this earthquake-linked claim.

March 26, 2015 12:19 pm

Anthony: You’ve failed to convert the 6,600 metric tons of emissions into CO2 equivalents. The press release does this for you. It says these 6,600 metric tons translate into 19.2 million metric tons CO2 equivalent (the IPCC assigns these gases very high global warming potentials). That’s roughly the same amount of CO2 about a half dozen coal plants would emit in a year. So the amount released during the earthquake is, on a CO2 equivalent basis, quite a bit larger than you suggest, but it is still very small in the grand scheme of things.

Rhee,
True, there’s no need to get the numbers correct when they’re all made up to begin with. Well, except for these numbers:comment image
First, this plot from NOAA and endorsed by the World Meteorological Organization (WMO) shows no uptick in CFC gases in 2011, suggesting that the effect of the Earthquake and Tsunami had no measurable global effect in atmospheric concentrations in 2011 or years afterwards through 2013.
Here’s some other stuff endorsed by the WMO: https://www.wmo.int/pages/themes/climate/causes_of_climate_change.php
This may or may not be a crowd-pleaser:
The main greenhouse gases include:
Water vapour. The most abundant greenhouse gas (GHG), however because it spends just a short time in the atmosphere, and humans have a very impact on the amount of water in the atmosphere, it is not considered the most important GHG.

Not so sure about the rest of it though.

March 27, 2015 3:32 pm

@ Saint…in the last 18 years atmospheric co2 has increased around 36 ppm, which equals 30% of the 120 ppm increase since the late 1700s. If the Tohoku Quake could cause a change that science was able to detect due to this tiny release, wouldn’t you think that science could detect the affect on the climate system from this enormous record setting addition of co2 over the last 18 years?

Dear J,
Tonight you can enjoy your first really good night’s sleep in years!
Re: “… the radio-isotopes leaking from the Fukashima plant” (you at 1:26pm today)
Here are the facts about Fukushima and nuclear radiation:
“At Fukushima a couple of weeks ago, some mildly radioactive water leaked into the sea. The volume of water was about equal to a dozen home swimming pools. In the ocean this really is a ‘drop in the ocean.’
The radiation content was so little that people could swim in the ocean without the slightest cause for concern. Any ocean naturally contains some radioactivity all of the time anyway. There is natural radiation around us all of the time and has always been there since the birth of the earth. ***
The water which is currently in the new Fukushima storage tanks has already been filtered to remove radioactive Cesium. All that is left is a bit of radioactive Tritium. Tritium is actually part of the water molecule. …
A rare hydrogen variation is … the Tritium form of hydrogen which has one proton plus two neutrons. … water molecules in which the Tritium isotope of the hydrogen atom is found are molecules referred to as ‘Heavy Water.’ … The Tritium heavy water is very mildly radioactive and is found normally in the sea all over the world all of the time. This Tritium concentration in the one thousand storage tanks at Fukushima is higher than that found naturally in the sea, but is still so low as to pose no real danger at all.”

But the heat isn’t quantified, so I have to assume that normally Japan’s emissions of those gasses cause 100 joules of heat to be trapped in the atmosphere but in the critical period 136 joules were trapped.
