POLES Fossil CCS may be in the wrong units

[gidden]

We noticed the following data for POLES

global_df.filter(variable='Carbon Sequestration|CCS|Fossil', model='POLES*').data

systematically reports significantly lower values for this variable than other SR15 scenarios. My guess is that values for this variable were reported in GtCO2/yr sequested rather than MtCO2/yr.

Here is an example from the SR15 low and no overshoot scenario set that includes a variety of other models (you can see POLES at the bottom)

Our best guess is that these are off (too low) by a factor of 100
