Scientists: Dinosaur Farts Caused Global Warming

Did Dinosaur Farts Cause Global Warming?

The Telegraph noted in 2010 that scientists believe that wooly mammoth farts helped create a warming period 13,000 years ago:

Mammoths helped to fill the atmosphere with methane and keep the Earth warm more than 13,000 years ago, scientists believe.

Together with other large plant-eating mammals that are now extinct, they released around 9.6 million tonnes of the gas each year, experts estimated.

When the ”megafauna” disappeared there was a dramatic fall in atmospheric methane which may have altered the climate.

Analysis of gases trapped in ice cores suggests that the loss of animal emissions accounted for a large amount of the decline.

”The changes in methane concentration at this time seem to be unique,” said the researchers, writing in the journal Nature Geoscience.

Not to be outdone, this week scientists said that dinosaur farts packed a much larger wallop.  As Reuters reports:

In a major new climate finding, researchers have calculated that dinosaur flatulence could have put enough methane into the atmosphere to warm the planet during the hot, wet Mesozoic era.

Just like big cows, their plant digestion was aided by methane-producing microbes.

“A simple mathematical model suggests that the microbes living in sauropod dinosaurs may have produced enough methane to have an important effect on the Mesozoic climate,” researcher Dave Wilkinson of Liverpool John Moores University said in a statement.

“Indeed, our calculations suggest that these dinosaurs could have produced more methane than all modern sources – both natural and man-made – put together,” Wilkinson said.

Methane is a potent greenhouse gas, with as much as 25 times the climate-warming potential as carbon dioxide.


Wilkinson and co-author Graeme Ruxton of the University of St. Andrews worked with methane expert Euan Nisbet at the University of London to make an educated guess about the degree to which gaseous emissions from sauropods could have warmed the atmosphere.


They reckoned that global methane emissions from sauropods were about 520 million tons per year, comparable to all modern methane emissions.

As we’ve repeatedly pointed out, both global warming “activists” and “skeptics” can agree on 6 things.

Perhaps we can agree on one more:  things probably smell better than they used to.

    The Telegraph noted in 2010 that scientists believe that wooly mammoth farts helped create a warming period 13,000 years ago” … “belief” as science?

    I noticed that there is no author for that piece, nor citations. It reminds me of the senate primary today in Indiana where Mourdock is running against Lugar in the republican primary. Mourdock calls himself a scientist, yet has only a master’s degree in geology. He is the state treasurer, not a working scientist.

    Good scientific papers list the scientists, the material, and the method used to reach a hypothesis.

    The Telegraph’s piece is an embarrassment. More methane is spewing daily into the Arctic now than was expected.

    The Reuters piece is likewise mere bloviation, beginning with “In a major new climate finding, researchers have calculated”, only to shortly thereafter “clarify” that with “A simple mathematical model suggests”. A mathematical model is not a researcher.

    As shown in my link above, even current mathematical models for methane have recently (within 6 months) been shown, by two scientific findings and reports, that they are grossly in error.

    Furthermore, remembering that the dinosaurs became extinct 65 million years ago during the K-T extinction event, and that speculation about their culinary and microbial internals is controversial, these two pieces are failures in terms of being scientifically credible.

    It was, in modern times anyway, a huge brain fart that caused current global warming induced climate change.

    Climate Science Goes Megalomaniacal

    A February 6 report in the Guardian describes budding efforts to displace decarbonizing with geo-engineering as the goal for reducing the predicted catastrophic effects of global warming. At present, these efforts are being funded by mega-wealthy private citizens like Bill Gates, but some traditional environmentalists as well as some decarbonizers are becoming worried that climate theory is setting off in a new direction. Perhaps that is why the story appeared in the Guardian of all places. Instead of its usual uncritical climate gushiness, the Guardian delves into the smarmier side of climate science — its dependence on money.

    The Whole World Has Chemtrail Alzheimers

    Alzheimer sufferers can’t remember things; can’t express themselves; and often sit and stare blankly. That is how we are all becoming. Look at people around you.

    Around the time the global Chemtrail spraying became severe (2000 to 2003) many people expressed how their memory had become poor. Now, people no longer seem to make the statement about having poor memory. This is why we need to pay attention. Once a change has happened, we take the new condition as being normal and our minds move on to looking for new things.

    We need to pay attention and we need to remember.

      Fill your vaporizer, humidifier with white vinegar …. watch the chemtrails evaporate. Build your personal negative ion plasma shield by evaporationg vinegar that has shown to neutralize decaying radiation, VOC’s, air pollution, dust, while providing positive health effects including restoration of brain neurons and lowering blood pressure.

    A human brain fart, i.e., deciding to become addicted to toxic, finite, fossil fuels, caused global warming.
