Critics of the global warming have warned all along that the entire hypothesis is based on computer models that project coming catastrophe based on incomplete, unknown data and unproven theories. Here's one one example.
Trump, meanwhile is rumored to be planning on reneging on his promise to pull us out of the Paris Accord today. Sad.
Arctic waters absorbed vast amounts of carbon dioxide from the atmosphere, creating a cooling effect that’s 230 times greater than the warming from methane emitted from underwater seeps, according to a new study.
The findings are a complete reversal of what scientists previously believed — that methane seeps in the Arctic Ocean were contributing to global warming.
“If what we observed near Svalbard occurs more broadly at similar locations around the world, it could mean that methane seeps have a net cooling effect on climate, not a warming effect as we previously thought,” John Pohlman, a U.S. Geological Survey biochemist and lead author of the study, said in a statement Monday.
If the results hold, Pohlman’s study could have big implications for how scientists calculate the global carbon “budget” and for future projections of global warming.
“These areas of methane seepage may be net greenhouse gas sinks,” reads a summary of the work.
Methane is a more potent gas than carbon dioxide, and scientists have become increasingly worried about “methane bomb” from thawing permafrost and warming oceans. Methane hydrates from the ocean floor “a key cause of the global warming that led to one of the largest extinctions in the earth’s history,” Ryo Matsumoto, a University of Tokyo professor, said in 2008.
Scientists worry a huge release of methane from the sea floor could cause massive amounts of warming. One 2016 study warned “the release of methane from hydrate may be apocalyptic.”
But Pohlman’s research suggests there’s a lot more to learn about methane seeps and their role in global greenhouse gas inventories.
