As theArctic shabu continues to fade away , some scientists have come up with ultra solution to the trouble of greenhouse gases . One of these idea is expectant - scale Carbon Capture and Storage ( CSS ) , bury those troublesome gases underground — but now it looks like that impression could cause more trouble than it ’s worth .

Mike Orcutt of Technology Reviewalerts usto a new paper in the Proceedings of the National Academy of Sciences which argues that CSS wo n’t work — because it could set off earthquakes , allowing the immobilize greenhouse gasses to escape .
Thepaper , author by Stanford researchers Mark Zoback and Steven Gorelick , is a leaden setback to those who are hoping to see CSS become a major player in climate ascendence . carbon paper sequestration works by transporting and pump the CO2 emitted by various industries into cloak-and-dagger geologic formations . The idea is to securely store it away from the atmosphere , a likely way of mitigating its contribution to global thawing .
But now it appears this is n’t such a beneficial idea — at least when it ’s done on a large scale .
In his TR article , Orcutt take down that the oil and gas pedal industry already uses techniques that are similar to CCS during imagination extraction and sewer water disposal — and these techniques are fuck to do small earthquakes . This practice has resulted in earthquakes in Arkansas , Ohio , and near the border of Colorado and New Mexico .
The author of the PNAS composition say that the peril can be managed through careful situation selection , but that bombastic - ordered series operation are more problematic . The challenge , they say , is rule a post that can keep a “ buoyant fluid ” in piazza for hundreds of 1000 of years .
Zoback and Gorelick mention that if carbon sequestration is to have an impact , it must be able to contain about 3.5 billion gross ton of carbon copy dioxide per class worldwide , which is an amount like to the nearly 30 billion barrels of crude oil the cosmos produces annually . But as Orcutt notes :
The most promising storehouse container are call deep saline aquifers - rock candy formations one to three kilometers underground , below the deepness of freshwater aquifer , and beneath a layer of impermeable rock called the caprock , which acts as a stamp . A modelling study by MIT investigator , publish to begin with this class in PNAS , estimated that deep saline aquifer in the United States could curb at least a 100 ’s worth of the carbon dioxide produce by the nation ’s ember - fired power industrial plant .
But this hypothesis has not been tested on a large scale , and Zoback doubt that some of the target repositing sites could safely hold as much C dioxide as assumed . Even small quakes could damage caprocks , say Zoback and Gorelick . That would threaten the integrity of carbon dioxide repositories , potentially allowing the greenhouse gas to run into the aura .
