I don't want to sound like I'm trivializing the scope of the problem, but there are articles about it almost every single day. There's only so much we can discuss as few of these seem to present genuinely novel information. At this point we know the science; the main barriers to action are political, and politics are generally considered beyond the scope of this forum. Again, I don't mean to trivialize it as I think that the subject should be getting much more attention, but let's face it, people come here for interesting discussion first and foremost.
