Disturbing resting seafloor CO2 is yet another way humans are believed to be heating up the planet.<\/strong><\/p>\n\n\n\n

Only 1% of the seafloor has been molested by dragging nets through the sand (trawling) in an effort to retrieve the seafood staples we enjoy. But that\u2019s enough to wreak havoc on the Earth\u2019s climate at the top of the atmosphere, 100 km above the ocean surface, where CO2-induced global boiling<\/a><\/strong> is activated.<\/p>\n\n\n\n

According to a new study<\/a><\/strong> and its press release<\/a><\/strong>, trawling the ocean floor for shrimp and cod disturbs the \u201cplanet-warming carbon dioxide\u201d that had until then been peacefully reposed in sentiment. Dragging nets along the ocean floor \u201cunlocks more carbon from the seafloor than all the world\u2019s airplanes emit each year,\u201d some 370 million metric tons worth.<\/p>\n\n\n\n

And, of course, this acidifies the ocean too. When in its undisturbed state, the massive quantities of seafloor CO2 hadn\u2019t been causing ocean acidification. But then as soon as the nets were dragged along the seafloor by humans, the disturbed CO2\u2019s acidification potential was unleashed.<\/p>\n\n\n\n

In others news along this front, we are told (O\u2019Bryan et al., 2021<\/a><\/strong>) that \u201cwild pigs are having a bigger climate change impact than one million cars\u201d because they are now, for the first time (ever?) trampling over dirt outside of their \u201cnative range.\u201d<\/p>\n\n\n\n

Had they stayed in their confined wild pig area, their \u201cnative range,\u201d the CO2 they released from the soil as they trampled across it would not have had any climate impact. But the dirt these wild pigs are disturbing now has CO2 in its at-rest state in it, and thus \u201cthis soil disturbance results in median emissions of 4.9 million metric tonnes (MMT) CO2 per year (equivalent to 1.1 million passenger vehicles).\u201d<\/p>\n\n\n\n

Wild pigs are now classified as an \u201cinvasive species\u201d delivering a previously unrecognized global carbon footprint \u201cthreat\u201d by uprooting soil outside of their lane.<\/p>\n\n\n\n
