ie. I added a couple of black lines on the left-hand side to show trends of the last few decades. I dropped the dust and methane graphs since I don't know numbers on them.
Note that the CO2 graph hasn't stopped heading up pretty much vertically on this plot, expected to hit at least 500 ppm by mid-century no matter what we do on energy alternatives. The temperature curve is lagging the CO2 curve by a few decades (at least) because of the ocean's thermal inertia - temperature is also going to keep heading up essentially vertically on this graph for several more degress at least, until we actually lower CO2 levels to pre-industrial amounts.
The 140,000 year graph isn't a hockey-stick, it's a delta-function pointing straight at human industrialization destabilizing the world.

How about this?
