Numerous Methane Leaks Found On Atlantic Sea Floor
sciencehabit writes Researchers have discovered 570 plumes of methane percolating up from the sea floor off the eastern coast of the United States, a surprisingly high number of seeps in a relatively quiescent part of the ocean. The seeps suggest that methane's contribution to climate change has been underestimated in some models. And because most of the seeps lie at depths where small changes in temperature could be releasing the methane, it is possible that climate change itself could be playing a role in turning some of them on.
No this is naturally occurring seeps. We have known about them in the past but recent discoveries have shown that more exist than was thought and with methane being 30x more potent of a green house gas than CO2 it throws the models and calculations off.
There is however the hypothesis that we create the CO2 that causes the base warming and the because we are warming the oceans it may be causing more methane to be released.
However, this is not known for sure and the extent at which methane is being released from natural sources is still in question.
From TFA-
"Even in the more likely event that aerobic microbes devour the methane while still in the ocean, it is converted to carbon dioxide, which leads to ocean acidification."
And let's break from the summary and go to the article for an even more damning quote(emphasis mine):
Jens Greinert, who heads the deep-sea monitoring unit at GEOMAR, downplays the effect of the new seeps on the atmosphere or ocean chemistry because the magnitude of the releases is dwarfed by human-associated inputs, such as livestock, or even other marine sites. “These little bits of bubbling here or there will not make a memorable impact,” Greinert says. He is more interested in what will happen as the world warms. “It becomes interesting only if you have a catastrophic release,” he says.
Clearly a troll, but for the benefit of anyone who may miss that point, I will simply state that there is no known mechanism for farts causing rain, whereas the greenhouse effect is a thoroughly understood and experimentally verified mechanism for CO2 causing warming.
