The realclimate.org graph (https://www.realclimate.org/images/Hansen88_forc.jpg) shows B as off the chart by 2020, but 1988 is around .2 and 2015 is around 1.45. Extending another 5 years, should be about 1.45 deg C difference by 2020.

The NASA chart shows a rise of about .7 during that time.

That's not a graph of temperature. It's a graph of the emissions (expressed as a forcing) that define each scenario. You want the one below it.

So it is, my apologies.
