Methane seeps may be slowing global warming
The water directly above methane seeps off the coast of Norway’s Svalbard archipelago absorb twice as much carbon dioxide (CO2) as surrounding waters, suggesting that release of the potent greenhouse gas may be slowing global warming. The same physical forces that are pushing the methane bubbles up are also pumping nutrient-rich cold waters from the sea bed to the surface, fertilising phytoplankton blooms that soak up CO2, according to a team led by John Pohlman of the US Geological Survey in Woods Hole, Massachusetts.
