This can cause large - scale algae blooms that could pull carbon dioxide out of the atmosphere in proportions significantly greater than whatever the microbes in those holes could pull down, Anesio says.

But Anesio's team has also found that organisms in these holes can have a cooling effect on the planet by actively sucking carbon dioxide out of the atmosphere through photosynthesis.

While glaciers and ice sheets may physically plug large stores of buried methane hydrates or pull carbon dioxide out of the atmosphere through millions of small holes, their impacts reach much further than their physical footprint.

However, as I wrote recently, most of those scenarios rely heavily on «negative emissions» — ways of pulling carbon dioxide out of the atmosphere.

In the former, we try to suck carbon dioxide out of the atmosphere and get it back in the ground; or we shunt CO2 aside at the smokestack before it gets to the atmosphere, and bury or store it; or we promote algae blooms that absorb CO2 at the ocean surface and then die off and carry it to the ocean floor.
