Doom and gloom or realism?
Humanity is in trouble with climate change. A recent article in Vox by David Roberts came to that conclusion. It begins with "There has always been an odd tenor to discussions among climate scientists, policy wonks, and politicians, a passive-aggressive quality, and I think it can be traced to the fact that everyone involved has to dance around the obvious truth, at risk of losing their status and influence. The obvious truth about global warming is this: barring miracles, humanity is in for some awful shit." The basis for that conclusion? Total carbon emissions to date, which are closely following the RCP 8.5 curve from the IPCC. That black curve is emissions to date. We as a civilization are on track to take carbon dioxide levels to around 1000 ppm by 2100 AD. The 12-month moving average of atmospheric CO 2 levels shows that we're already at 398.83 and still accelerating upward. That locks us into at least 1.53ºC of total warming as of now,
