Atmospheric carbon dioxide passes 400ppm
We are in deep shit.<p>We can change, or we can die. Continued emissions at our current rate <i>will</i> kill us. We&#x27;re already teetering at the precipice of feedback loops and may be committed to some.<p>At this point, we need a Manhattan-Project-level effort to end carbon emissions as we know them. Else we just have to hope that colonies on Mars and the Moon will be able to sustain the species while we nuke ourselves over resource wars here on Earth.<p>The problem is worse than most people know. It doesn&#x27;t help that we have a segment of the population here in the US that is willing to ignore all evidence on the issue.
