The Toronto scientists say that as Earth’s temperatures cooled, oxygen was drawn into the ocean, where it oxidized organic matter, releasing the greenhouse gas carbon dioxide into the atmosphere.

Total BS. CO2 would have been "drawn into the ocean" as a result of the falling temperature, leaving less to participate in the mythical atmospheric greenhouse warming. Nature obviously published this because it supports the AGW hoax. If in fact there is evidence that the oceans did not completely freeze, a more sensible explanation is that it was due to the mass of the oceans and the enormous amount of heat required to be removed.

Actually the amount of CO2 they are talking about would actually warm the planet.
Right now we have 0.03% CO2 they are talking about +13% CO2 (toxic levels) or 350 times more CO2 then we have today.
