https://www.vox.com/2016/10/4/13118594/2-degrees-no-more-fos... "This image should terrify you. It should be on billboards. As you can see, in either scenario, global emissions must peak and begin declining immediately. For a medium chance to avoid 1.5 degrees, the world has to zero out net carbon emissions by 2050 or so — for a good chance of avoiding 2 degrees, by around 2065. After that, emissions have to go negative. Humanity has to start burying a lot more carbon than it throws up into the atmosphere. ... Thus far, most demonstration plants of any size attaching [carbon capture] to fossil fuel facilities have been over-budget disasters. What if we can’t rely on it? What if it never pans out?" |
