I saw it coming and I loved it . Bravo ! <| sep |> You ' re good . I ' m using a fairly broad definition of posting history anyway . <| sep |> Dieses Kommentar hat mich extrem beunruhigt <| sep |> In true mexican Bienvenidos al club de los pitudos <| sep |> I travel north for Ikea in Montreal . I really need to swing over to Costco for the Poutine then . <| sep |> Expanding on the we don ' t know how to do that Removing CO 2 from the air requires energy . How much isn ' t entirely clear yet , but if we want to do it properly , it ' s a bit more than we received by burning trillions of tons of coal over the last centuries . All of this energy needs to go into the machines that convert CO 2 into rock or into synthetic coal . We haven ' t invented machines that can do that , but let ' s just assume that they can be built instantaneously , need no space or resources and their construction is completely free . The energy required just to catch all of the US emissions would cost as much as five Iraq wars . Every year . Without even starting to make a dent into the atmospheric CO 2 levels , just keeping them stable . And obviously you can ' t use fossil fuels to generate that energy . In fact , you ' ll need to build so many renewable power plants that even the emissions that come from building solar cells or wind turbines will become a huge problem . By the way , there isn ' t that much wind energy in the atmosphere about 400 TW in total , if I remember correctly . We ' re already extracting 0 . 5 % of that .
